Abstract

A sensor system that provides an adjustable threshold level for the sensed quantity is described. The adjustable threshold allows the sensor to adjust to ambient conditions, aging of components, and other operational variations while still providing a relatively sensitive detection capability for hazardous conditions. The adjustable threshold sensor can operate for extended periods without maintenance or recalibration. A portable monitoring unit working in communication with the sensor system provides immediate communication of conditions detected by the sensors. The portable monitoring unit allows building or complex management to be in communication with a sensor system at all times without requiring someone to be physically present at a monitoring site. The portable monitoring unit can be equipped with an auditory device for alerting management or a screen for displaying pertinent information regarding an occurring situation so that management can quickly identify and resolve the problem. In addition, the portable monitoring unit can also be equipped with function keys that allow the portable monitoring unit to send instructions back to the sensor system. In one embodiment, the portable monitoring unit also includes a second transceiver for communications over a short wave radio frequency, or with a cellular phone system.

Description

PORTABLE MONITORING SYSTEM FIELD OF THE INVENTION The present invention is concerned with a detector in a wired or wireless detector system for monitoring potentially dangerous or costly conditions such as for example smoke, temperature, water, gas and the like. It is also concerned with a portable monitoring unit to monitor conditions present in a building or complex.

BACKGROUND OF THE INVENTION The maintenance and protection of a building or complex and its occupants is difficult and expensive. Some conditions, such as fires, gas leaks, etc. It is a danger to the occupants and the structure. Other malfunctions, such as water leaks on roofs, plumbing, etc., are not necessarily dangerous for the occupants, but can nonetheless cause considerable damage. In many cases, an adverse condition such as water leakage, fire, etc., is not detected in the early stages when the damage and / or danger is relatively small. This is particularly true for apartment complexes where there are many individual units and supervisory and / or maintenance personnel that do not have unrestricted access to the apartments. When a fire or other dangerous condition, the occupant may be away from home, asleep, etc., and the fire alarm system may not signal an alarm in time to prevent further damage or loss of life. Detectors can be used to detect such adverse conditions, but the detectors have their own set of problems. For example, adding detectors such as for example smoke detectors, water detectors and the like in an existing structure can be prohibitively expensive due to the cost of installing the wiring between the remote detectors and a central monitoring device used to monitor the detectors. The addition of wiring to provide power to the detectors further increases the cost. In addition, with respect to fire detectors, most fire departments do not allow automatic notification of the fire department based on data from a smoke detector alone. Most fire departments require that a specific temperature rise rate be detected before an automatic fire alarm system can notify the fire department. Unfortunately, the detection of fire by the rise in temperature in general means the fire is not detected until it is too late to prevent further damage. Complicating this problem, alarm systems do not provide real measured data (eg, measured smoke levels) to a remote monitoring panel. Typical fire alarm system is set to detect a threshold level of smoke (or temperature) and trigger an alarm when the threshold is reached. Unfortunately, the threshold level must be set relatively high to avoid false alarms and to allow natural aging of components and to allow natural variations in the environment. Setting the threshold to a relatively high level avoids false alarms, but reduces the effectiveness of the detector and can unnecessarily put people and property at risk. Such a system is simple to operate but does not provide sufficient "early warning" capability to allow supervisory personnel to respond to a fire at very early bases. In addition, even in a system with central or remote monitoring capabilities, someone must be present at all times in the monitoring site to see what happens, increasing the cost of monitoring.

BRIEF DESCRIPTION OF THE INVENTION These and other problems are solved by providing a detector system that provides detector information to a portable monitoring unit ("PMU") to alert the administration of the building or complex or other responsible parties to a problem potential detected by the system of detector. The PMU allows the administration of the building or complex to be in communication with the detector system without requiring that someone be physically present at a monitoring site. In this regard, when a detector communicates an alarm or other warning, the administration of the building or complex will quickly take over the situation. The premature warning allows the administration to determine the situation and take premature action, thereby reducing the danger to the structure and to any present occupant. In one modality, the PMU operates in communication with the detector monitoring system of a building, apartment, office, residence, etc. If the detector system determines that the condition is an emergency (for example, smoke has been detected), then the detector system sends an alert message to the PMU. If the detector system determines that the situation guarantees a report but it is not an emergency (for example, low battery), the detector system may send a warning message to the PMU or may record the data for later reporting. Non-emergency information reported by the detectors can later be sent to the PMU upon request or after the presence of a predefined event. In this way, the building administration can be informed of the conditions around the building without having to be present at a central site. In one mode, the detector system detects and reports conditions such as, for example, smoke, temperature, humidity, humidification, water, water temperature, carbon monoxide, natural gas, propane gas, other flammable gases, radon, poisonous gases, etc. . In one embodiment, the PMU may be small enough to be carried in one hand, carried in a pocket, or fastened to a belt. In one mode, the PMU has a screen to display communications. In one mode, the PMU has one or more buttons or function keys to assist in communication with the monitoring computer, repeaters or detectors. The function keys can be communicated to communicate one or more of the following: acknowledgment of message from the monitoring computer, OK - it has been taken from the situation or is a false alarm, to carry out diagnostic verification - that verify the status work detectors and repeaters, call the fire department, call the occupant, alert others; turn on / off power, talk to others or the owner, scroll through the screen, adjust the volume, as well as any other communication or instruction that may be useful in a PMU. The PMU may also include a tranceptor in communication with a controller. The tranceptor can be configured to send and receive communications between a monitoring computer and the controller. The controller can be configured to send an electrical signal to a screen or an audio device in order to alert management that a condition occurs. The controller may be configured to send and / or receive an electrical signal from a microphone, user input keys, detector programming interface, a location detector device or a second tranceptor for secondary communication channels (eg telephone). cellular communication from walkie talkie). The controller can also be connected to a computer interface, such as, for example, a USB port, in order to communicate via wiring with a computer. In one mode, the PMU can be configured to receive and send communication with a monitoring computer, repeaters or detectors. For example, the monitoring computer may send an alert message indicating that a serious condition is occurring. The PMU can display the message on the screen or sound an alarm or cause a previously recorded message to be played. The screen may include any and all relevant information required to determine the situation such as the type of alert (eg, fire) any relevant information about the alert (eg, smoke rise speed or temperature), the number of apartment or unit, the specific room where the detector is located, the number telephone of the occupants, if others have been notified or have recognized the alert, as well as any other relevant information to determine the situation. In one embodiment, the PMU may be configured to receive and communicate warning messages. For example, the monitoring computer may send a message to the PMU that warns that a battery is low in a particular detector, that a detector has been tampered with, that a heating unit or air conditioning unit needs maintenance, that A leak of water or any other relevant information has been detected that may be useful for the maintenance of a complex or building. In one embodiment, the PMU may be configured to receive a diagnostic check of the detectors. The diagnostic verification can verify the battery level of the detectors and repeaters, as well as verify the work status of each detector or repeater or see if one needs repair or replacement. The diagnostic verification can also verify the status of the heating, ventilation and air conditioning systems. Diagnostic verification can also be used to monitor any other conditions useful in the maintenance of a building or complex. In a modality, depending on the severity of the alarm, when the monitoring computer communicates a message To the PMU such as an alert, the monitoring computer can wait for an acknowledgment communication to be sent from the PMU to the monitoring computer. If an acknowledgment is not received, the monitoring computer may attempt to contact other PMUs or may attempt to contact the administration through other communication channels, for example, through a telephone communication, a cell phone or another wireless communication, a radiolocator or through the Internet. If the monitoring computer is still not able to contact the administration, the monitoring computer can alert the fire department directly that a situation is occurring in the building or complex. In one mode, the monitoring computer can also alert nearby units that a situation near them is occurring. If an acknowledgment is received, depending on the severity of the alert, the monitoring computer may also wait for additional instructions from the PMU. These instructions may include an OK communication that alerts the monitoring computer that has been taken of the situation or is simply a false alarm; an instruction to call the fire department, an instruction to call the owners; an instruction to alert others or any other instruction useful to deal with the situation. If additional instructions are not received, the monitoring computer may resend the alert, request additional instructions to the PMU, try to contact other PMUs or you can try to contact the administration through other channels, for example, through a telephone, cell phone or other communication wireless, a radiolocator or through a network. If the monitoring computer is still not able to contact another administration and fails to receive additional instructions, the monitoring computer may alert the fire department directly to a situation in the building or complex. In one mode, the severity or priority of the alarm may be based on the level of smoke, gas, water, temperature, etc., detected, the amount of time the detector has been alerting, the rate of rise of the substance detected, the number of detectors that alert the situation or any other detector information useful to determine the security or priority level of the situation. In one embodiment, an adjustable bran allows the detector to adjust to environmental conditions, aging of the components and other operational variations while still providing a relatively sensitive detection capability for hazardous conditions. The adjustable threshold detector can operate for an extended period of operability without maintenance or recalibration. In In one embodiment, the detector is self-calibrated and runs through a calibration sequence at the beginning or at periodic intervals. In one embodiment, the adjustable threshold detector is used in an intelligent detector system that includes one or more intelligent detector units and a base unit that can communicate with the detector units. When one or more of the detector units detects an anomalous condition (eg, smoke, fire, water, etc.) the detector unit communicates with the base unit and provides data regarding the anomalous condition. The base unit may be contacted by a supervisor or other responsible person by a technical plurality; such as by means of a PMU, telephone, pager, cell phone, Internet (and / or local area network), etc. In one embodiment, one or more wireless repeaters are used between the detector units and the base unit to extend the range of the system and allow the base unit to communicate with a larger number of detectors. In one embodiment, the adjustable threshold detector adjusts a threshold level according to an average value of the detector reading. In one modality, the average value is a relatively long-term average. In one embodiment, the average is a time-weighted average where the recent detector readings used in the premediation process are weighted differently than the readings of the less recent detector. The average is used to adjust the threshold level. When the detector reading rises above the threshold level, the detector indicates an alarm condition. In one embodiment, the detector indicates an alarm condition when the detector reading rises above the threshold value for a specified period of time. In one embodiment, the detector indicates an alarm condition when a statistical number of detector readings (e.g., 3 of 2, 5 of 3, 10 of 7, etc.) are above the threshold level. In one mode, the detector indicates several levels of alarm (for example, notification, alert, alarm) on the basis that, when operating above the threshold, the detector reading has risen and / or how quickly the detector reading has risen. In one embodiment, the detector system includes a number of detector units located throughout an orifice that detect conditions and report anomalous results back to a central reporting station. The detector units measure conditions that could indicate a fire, water leak, etc. The detector units report the data read to the base unit whenever the detector unit determines that the measured data is sufficiently anomalous to be reported. The base unit can notify a responsible person such as, for example, the building administrator, building owner, security service private, etc. In one embodiment, the detector units do not send an alarm signal to the central location. Rather, the detectors send quantitative measured data (eg, smoke density, temperature rise rate, etc.) to the central reporting station. In one embodiment, the detector system includes a battery-operated detector unit that detects a condition such as, for example, smoke, temperature, humidity, wetting, water, water temperature, carbon monoxide, natural gas, propane, other flammable gases, radon, poisonous gases, etc. The detector unit placed in a building, apartment, office, residence, etc. In order to save battery power, the detector is normally placed at a low power consumption. In one embodiment, while in the low power consumption mode, the detector unit takes regular reader readings, adjusts the threshold level and evaluates the readings to determine if an animal condition exists. If an abnormal condition is detected, then the detector unit "wakes up" and begins to communicate with the base unit or with a repeater. At programmed intervals, the detector also "wakes up" and sends status information to the base unit (or repeater) and then hears commands for a period of time. In one embodiment, the detector unit is bidirectional and is configured to receive instructions from the central report station (or repeater). Thus, as for example, the central reporting station can instruct the detector to: perform additional measurements; advance to standby mode; that wakes up; to report the status of the battery; to change the interval of awakening; to perform self-diagnosis and report results; to report your threshold level, change your threshold level, change your threshold calculation equation, change your alarm calculation equation, etc. In one embodiment, the detector unit also includes a tamper switch. When tampering is detected with the detector, the detector reports such tampering to the base unit. In one mode, the detector reports its general health and status to the central reporting unit on a regular basis (eg, self-diagnosis results, battery health, etc.). In one embodiment, the detector unit provides two wake-up modes, a first wake-up mode for taking measurements (and reporting such measurements if deemed necessary) and a second wake-up mode for listening to commands from the central reporting station. The two modes of awakening or combinations thereof may occur at different intervals. In one embodiment, the detector units use spread spectrum techniques to communicate with the base unit and / or the repeater units. In one modality, the Detector units use spectrum spread hopping frequency. In one embodiment, each detector unit has an identification code (ID) and the detector units append their ID to the outgoing communication packets. In one embodiment, when receiving wireless data, each detector unit ignores data that is intended for other detector units. The repeater unit is configured to relieve communications traffic between a number of detector units and the base unit. The repeater units commonly operate in an environment with several other repeater units and thus, each repeater unit contains a database (eg, a look-up table) of the detector ID. During normal operation, the repeater only communicates with the designated wireless detector units whose IDs appear in the repeater database. In one embodiment, the repeater is put into battery operation and saves energy by maintaining an internal radius of when its designated detectors are expected to transmit and advance to a low power consumption mode when none of its designated detector units is programmed to to transmit. In one embodiment, the repeater uses spread spectrum to communicate with the base unit and the detector units. In one embodiment, the repeater uses frequency bank spread spectrum to communicate with the base unit and the detector units.

In one embodiment, each repeater unit has an ID and the repeater unit append its ID to the outgoing packets that originate in the repeater unit. In one embodiment, each repeater unit ignores data that is designated to other repeater units or to detector units that are not serviced by the repeater. In one mode, the repeater is configured to provide bidirectional communication between one or more detectors and a base unit. In one mode, the repeater is configured to receive instructions from the central (or repeater) reporting station. Thus, as for example, the central reporting station can instruct the repeater to: send command to one or more detectors; move forward to a standby mode; that "wake up"; to report the status of the battery; to change the interval of awakening; to run self-diagnosis and report results; etc. The base unit is configured to receive detector read data from a number of detector units. In one embodiment, the detector information is relayed through the repeater units. The base unit also sends commands to the repeater units and / or detector units. In one embodiment, the base unit includes PCs without a floppy disk running from a CD-ROM, flash memory, DVD, or other read-only device, etc. When the base unit receives data from a wireless detector that indicates that it can If there is an emergency condition (for example, a fire or excessive smoke, temperature, water, flammable gas, etc.) the base unit will try to notify a responsible party (for example, the building manager) through several channels of communication (for example, telephone, Internet, pager, cell phone, etc.). In one embodiment, the base unit sends instructions to place the wireless detector in an alert mode (inhibiting the low power consumption mode of the wireless detector). In one embodiment, the base unit sends instructions to activate one or more additional detectors near the first detector. In one embodiment, the base unit maintains a database of health, battery status, signal strength and current operating status of all detector units and repeater units in the wireless detector system. In one mode, the base unit automatically performs routine maintenance by sending commands to each detector to run a self-diagnosis and report the results. The base unit collects such diagnostic results. In one embodiment, the base unit sends instructions to each detector telling the detector how much to wait for the "wake up" interval. In one mode, the base unit schedules different wake-up intervals to different detectors based on the health of the detector, battery health, location, etc. In one mode, the base unit sends instructions to repeaters to channel detector information around a failed repeater.

DETAILED DESCRIPTION OF THE PREFERRED MODE Figure 1 shows a detector system 100 including a plurality of detector units 102-106 communicating with a base unit 112 by means of a number of repeater units 110-111. The detector units 102-106 are located throughout a building 102. The detector units 102-104 communicate with the repeater 110. The detector units 105-106 communicate with the repeater 111. The repeaters 110-111 communicate with each other. with the base unit 112. The base unit 112 communicates with a monitoring computer system 113 by means of a network connection of computer such as, for example, Ethernet, wireless Ethernet, security server port, main serial port of universal serial (USB), bluetooth, etc. The computer system 113 can all be put together with the building administrator, maintenance service, alarm service or other responsible personnel 120 using one or more of several communication systems such as, for example, PMU 125, telephone 121, pager 122, cell phone 123 (for example, direct contact, voice mail, text, etc.), and / or via the Internet and / or local area network 124 (e.g., via email, instant messaging, network communications, etc.). In one embodiment, multiple base units 112 are provided to the monitoring computer 113. In one embodiment, the monitoring computer 113 that is provided to more than one computer monitor, thus allowing more data to be displayed than can be conveniently displayed on a single monitor. In one embodiment, the monitoring computer 113 is provided to multiple monitors located at different sites, thereby allowing data from the monitoring computer 113 to be displayed at multiple sites. The detector units 102-106 include detectors for measuring conditions such as, for example, smoke, temperature, humidity, water, water temperature, humidity, carbon monoxide, natural gas, propane gas, alarm security, instructional alarms (for example, open doors, broken windows, open windows, and the like); other flammable gases, radon, poisonous gases, etc. Different detector units can be configured with different detectors or combinations of detectors. Thus, for example, in one installation the detector units 102 and 104 could be configured with smoke and / or temperature detectors while the detector unit 103 could be configured with a humidity detector. The discussion that follows generally refers to the detector unit 102 as an example of a detector unit, with the understanding that the description of the detector unit 102 can be applied to many detector units. Similarly, the discussion generally refers to repeater 110 by way of example and not limitation. It will also be understood by that ordinarily in the art that repeaters are useful for extending range of detector units 102-106 but are not required in all modes. Thus, for example, in one embodiment, one or more of the detector units 102-106 can communicate directly with the base unit 112 without going through a repeater. It will also be understood by one of ordinary skill in the art that Figure 1 shows only five detector units (102-106) and two repeater units (110-111) for purposes of illustration and not as limitation. An installation in a large apartment or complex building would commonly involve many detector units and repeater units. In addition, one of ordinary skill in the art will recognize that a repeater unit can service relatively many detector units. In one embodiment, the detector units 102 can communicate directly with the base unit 112 without going through a repeater 111. When the detector unit 102 detects an abnormal condition (e.g., smoke, fire, water, etc.). ) the detector unit communicates with the repeater unit 110 and provides data with respect to the anomalous condition. The repeater unit 110 sends the data to the base unit 112, and the base unit 112 sends the information to the computer 113. The computer 113 evaluates the data and takes the appropriate action. If the computer 113 states that the condition is an emergency (eg, fire, smoke, large amounts of water), then the computer 113 contacts the appropriate personnel 120. If the computer 113 determines that the situation warrants reporting but it is not an emergency, then the computer 113 can record the data to report later or it can send a warning message to the PMU 125. In this way, the detector system 100 can monitor the conditions in and around the 101 building. In one embodiment, the detector unit 102 has a Internal power source (for example, battery, solar cell, fuel cell, etc.). In order to save energy, the detector unit 102 is normally placed in a low power consumption mode. In one embodiment, using sensors that require relatively little power, while in the low power consumption mode, the detector unit 102 takes regular detector readings and evaluates the readings to determine if an abnormal condition exists. In one embodiment, using the detectors that require relatively more energy, while in the low power consumption mode, the detector unit 102 takes and evaluates detector readings at periodic intervals. If an abnormal condition is detected, then the detector unit 102"wakes up" and begins to communicate with the base unit 112 by means of the repeater 110. At scheduled intervals, the detector unit 102"wakes up" and sends status information ( for example, energy levels, self-diagnosis information, etc.) to the base unit (or repeater) and then listen to command for a period of time. In one embodiment, the sensor unit 102 also includes a tamper detector. When tampering with the detector unit 102, the detector unit 102 reports such tampering to the base unit 112. In one embodiment, the detector unit 102 provides bidirectional communication and is configured to receive data and / or instructions from the base unit 112. Thus, for example, the base unit 112 can instruct the detector unit 102 to perform additional measurements, advance to a standby mode , that wakes up, that reports the status of the battery, that it changes the interval of awakening, that it runs self-diagnosis and reports results, etc. In one embodiment, the detector unit 102 reports its general health and its status on a regular basis (eg, result of self-diagnosis, battery health, etc.). In one embodiment, the detector unit 102 provides two wake-up modes, a first wake-up mode for taking measurements (and reporting such measurements if deemed necessary) and a second wake-up mode for listening to commands from the central reporting station. The two modes of awakening or combinations thereof may occur at different intervals. In one embodiment, the detector unit 102 uses spread spectrum techniques to communicate with the repeater unit 110. In one embodiment, the detector unit 102 utilizes frequency hopping spread spectrum. In one embodiment, the detector unit 102 has an address or identification code (ID) that distinguishes the detector unit 102 from the other detector units. The detector unit 102 append its IDs to the communication packets outgoing, such that the transmissions of the detector unit 102 can be identified by the repeater 110. The repeater 110 append the ID of the detector unit 102 to data and / or instructions that are transmitted to the detector unit 102. In one embodiment, the detector unit 102 data and / or instructions that are intended for other detector units. In one embodiment, the detector unit 102 includes a reset function. In one embodiment, the reset function is activated by the reset switch 208. In one embodiment, the reset function is active for a prescribed time interval. During the reset interval, the tranceptor 203 is in a reception mode and can receive the identification code of an external programmer. In one embodiment, the external programmer wirelessly transmits a desired identification code. In one embodiment, the identification code is programmed by an external programmer that is connected to the detector unit 102 by means of an electrical connector. In one embodiment, the electrical connection to the detector unit 102 is provided by sending modulated control signals (energy line carrier signals) through a connector used to connect the power source 206. In one embodiment, the external programmer it provides signals of energy and control. In one modality, the External programmer also programs the type of detector (s) installed in the detector unit. In one embodiment, the identification code includes an area code (e.g., apartment number, zone number, floor number, etc.) and a unit number (e.g., unit 1, 2, 3, etc.). ). In one embodiment, the PMU is used to program the detector unit 102. In one embodiment, the detector communicates with the repeater in the 900 MHz bands. This band provides good transmission through walls and other obstacles normally found in and. around a construction structure. In one embodiment, the detector communicates with the repeater in bands above and / or below the 900 MHz band. In one embodiment, the detector, repeater and / or base unit listens to a radio frequency channel before transmitting. on that channel or before the transmission begins. If the channel is in use (for example, by another device such as another repeater, cordless telephone, etc.) then the detector, repeater and / or base unit changes to a different channel. In one embodiment, the detector, repeater and / or base unit coordinates the frequency hop to listen to radio frequency channels for interference and use an algorithm to select a next channel for transmission that emits interference. In one mode, if the detector detects a dangerous condition and advances to a continuous transmission mode, the detector will test (for example, listen to) the channel before transmission to avoid channels that are blocked, in use or stuck. In one mode, the detector continues to transmit data from a base reality acknowledgment that the message has been received. In one embodiment, the detector transmits data that have normal priority (e.g., status information) does not seek an acknowledgment and detector transmits data that has high priority (e.g., excess smoke, temperature, etc.) until a signal is received. accuse The repeater unit 110 is configured to relieve communications traffic between the detector 102 (and similarly, the detector units 103-104) and the base unit 112. The repeater unit 110 commonly operates in an environment with several units of repeater (such as repeater unit 111 in FIG. 1) and thus, repeater unit 110 contains a database (e.g., a look-up table) of ID of the detector unit. In Figure 1, the repeater 110 has database entries for the IDs of the detectors 102-104, and thus the detector 110 will communicate with the detector units 102-104. In one embodiment, the repeater 110 has an internal power source (eg, battery, solar cell, fuel cell, etc.) and saves energy by maintaining an internal schedule of when the detector units 102-104 are expected to transmit. In one embodiment, the repeater unit 110 to a low power mode of energy when none of its designated detector units is programmed to transmit. In one embodiment, the repeater 110 uses spread spectrum techniques to communicate with the base unit 112 and the detector units 102-104. In one embodiment, the repeater 110 utilizes frequency hopping spread spectrum to communicate with the base unit 112 and the detector units 102-104. In one embodiment, the repeater unit 110 has an address or identification code (ID) and the repeater unit 110 append its address to outgoing communication packets that originate in the repeater (ie, packets that are not sent ). In one embodiment, the repeater unit 110 ignores data and / or instructions that are intended for other repeater units or repeater units that are serviced by the repeater 110. In one embodiment, the base unit 112 communicates with the detector unit 102 when transmitting a communication packet destined to the detector unit 102. Both of the repeaters 110 and 111 receive the communication packet destined to the detector unit 102. The repeater unit 111 ignores the communication packet. allocated to the detector unit 102. The repeater unit 110 transmits the communication packet destined to the detector unit 102 to the detector unit 102. In one embodiment, the detector unit 102, the repeater unit 110 and the unit of base 112 it communicate using frequency hopping spread spectrum (FHSS), also known as channel hopping. Wireless frequency hopping systems offer the advantage of avoiding other interfering signals and avoiding collisions. In addition, there are regulatory advantages given to systems that do not transmit continuously on a frequency. Channel skip transmitters change in frequency after a period of continuous transmission or when interference is encountered. These systems can have a higher transmission power and relaxed limitations in the band spurious. FCC regulations limit the transmission time on a channel to 400 milliseconds (averaged in 10-20 seconds depending on the channel bandwidth) before the transmitter needs to change frequency. There is a minimum frequency stage when changing channels to resume transmission. If there are 25 to 49 frequency channels, the regulations allow an effective radiated power of 24 dBm, the repudios must be -20 dBc and the harmonics must be -41.2 dBc. With 50 or more channels, the regulations allow the effective radiant power to be up to 30 dBm. In one embodiment, the detector unit 102, the repeater unit 110 and the base unit 112 communicate using FHSS where the frequency hopping of the detector unit 102, the repeater unit 110 and the base unit 112 do not they are synchronized in such a way that in anyAt any given moment, the detector unit 102 and the repeater unit 110 are in different channels. In such a system, the base unit 112 communicates with the detector unit 102 using the hopping frequency synchronized to the repeater unit 110 in place of the detector unit 102. Then the repeater unit 110 sends the data to the unit. of detector using hopping frequencies synchronized with the detector unit 102. Such a system extensively avoids collisions between the transmissions by the base unit 112, the PMU 125 and the repeater unit 110. In one embodiment, all the detector units 102- 106 use FHSS and the detector units 102-106 are not synchronized. Thus, at any given time it is unlikely that any of two or more detector units 102-106 will transmit on the same frequency. In this way, collisions are avoided widely. In one embodiment, the collisions are not detected but tolerated in the system 100. If collisions occur, the data loss due to the collision are effectively retransmitted the next time the detector units transmit detector data. When the detector units 102-106 and the repeater units 110-111 operate in asynchronous mode, then a second collision is highly unlikely because the units causing the collisions have treated different channels. In one mode, the detector units 102-106, repeater units 110-111, PMU 125 and the base unit 112 use the same ratio of tazo. In one embodiment, detector units 102-106, repeater units 110-111, PMU 125 and base unit 112 use the same pseudo-random algorithm to control channel hopping but with different starting speeds. In one embodiment, the seed starting for the hopping algorithm is calculated from the ID of the detector units 102-106, repeater units 110-111, PMU 125 or the base unit 112. In an alternative embodiment, the unit The base unit communicates with the detector unit 102 when sending a communication packet to the repeater unit 110, wherein the packet sent to the repeater unit 110 includes the address of the detector unit 102. The repeater unit 102 extracts the address of the detector unit 102 to the packet and creates and transmits a packet destined to the detector unit 102. In one embodiment, the repeater unit 110 is configured to provide bidirectional communication between its detectors and the base unit 112. In In one embodiment, the repeater 110 is configured to receive instructions from the base unit 112. Thus, for example, the base unit 112 can instruct the repeater because: I sent command to one or more detectors; of advance to the standby mode; "wake up"; report of battery status; change the interval of awakening; execute self-diagnosis and report results; etc.

The base unit 112 is configured to receive data from the attached detector of a member of detector units either directly or by means of the repeaters 110-111. Base unit 112 also sends commands to repeater units 110-111 and / or detector units 102-106. In one embodiment, the base unit 112 communicates with a computer 113 without a disk running from a CD-ROM. When the base unit 112 receives data from the detector units 102-106 which indicate that there may be an emergency condition (e.g., fire or excessive smoke, temperature, water, etc.) the computer 113 will attempt to notify the Responsible party 120. In one embodiment, the computer 112 maintains a database of health, energy status (e.g., battery charge) and current operating status of all detector units 102-106 and units of repeater 110-111- In one embodiment, computer 113 automatically performs routine maintenance by sending commands to each detector unit 102-106 to perform a self-diagnosis and report the results. Computer 113 collects and such results diagnose. In one embodiment, computer 113 sends instructions to each detector unit 102-106 that tell the detector how much to wait between "wake-up" intervals. In one embodiment, the computer 113 schedules different wake-up intervals to different detector units 102-106 based on health, energy status, detector location, etc. In one embodiment, the computer 113 schedules different wake-up intervals to different detector units 102-106 based on the type of data and urgency of the data collected by the detector unit (for example, the detector units may have smoke detectors). and / or temperature producing data that must be verified relatively more frequently than detector units having humidity detectors or wetting detectors). In one embodiment, the base unit sends instructions to repeaters to route the detector information around a failed repeater. In one embodiment, computer 113 produces a screen that tells maintenance personnel which detector units 102-106 need repair or maintenance. In one embodiment, computer 113 maintains a list that shows the status and / or location of each detector according to the ID of each detector. In one embodiment, the detector units 102-106 and / or the repeater units 110-111 measure the intensity of the received wireless signals (eg, the detector unit 102 measures the intensity of the signals received from the repeater unit. 110, the repeater unit 110 measures the signal strength received from the detector unit 102 and / or the base unit 112). The detector units 102-106 and / or the repeater units 110-111 report such signal strength measurement back to the computer 113. The computer 113 evaluates the signal strength measurements to inquire into the health and robustness of the detector system 100. In one embodiment, the computer 113 it uses the signal strength information to re-route the wireless communications traffic in the detector system 100. Thus, for example, if the repeater unit 110 goes offline or is having difficulty communicating with the detector unit 102, the computer 113 can send instructions to the repeater unit 111 to add the ID of the detector unit 102 to the database of the repeater unit 111 (and similarly, send instructions to the repeater unit 110 to remove the ID of the detector unit 102), thereby routing the traffic for the detector unit 102 by means of the router unit 111 in place of the router unit 110 In one embodiment, a PMU 125 communicates with the detector system 100. It will be understood by the person skilled in the art that the PMU 125 can communicate with various detector systems. The following description of the PMU 125 is proposed by way of communication and not by way of limitation. In one embodiment, the monitoring computer 113 sends any required communication to the PMU 125 that transports the information to the 120 administration.

The monitoring computer 113 can send the communication through the base unit 112 or through any communication channels. Optionally, the detector units and repeater units can communicate directly with the PMU 1. In one embodiment, one or more PMUs can communicate with the monitoring computer 113 at the same time. The PMU 125 may be individually configured such that only certain PMUs can communicate with the system or PMU 125 may be configured to communicate with multiple systems. The PMU 125 may also be configured to identify the user. Different levels of authorization can be given to different users to allow different levels of access to the detector system. In one embodiment, the PMU 125 uses spread spectrum techniques to communicate with the detector units, repeater units or base unit 112. In one embodiment, the PMU 125 utilizes frequency hopping spread spectrum. In one embodiment, the PMU 125 has an address or identification code (ID) that distinguishes it from the PMU 125 of the other PMU. The PMU 125 can append its ID to the communication packets also in such a way that the transmissions of the PMU 125 can be identified by the database 112, detector units or repeater units. In one mode, the detector units, the repeater units, the base unit and the PMU 125 communicate using FHSS where the frequency hopping of the detector units, the repeater units, the base unit and the PMU 125 are not synchronized in such a manner at any given time , the detector units and the repeater units are in different channels. In such a system, the base unit 112 or PMU 125 communicates with the detector units using the hopping frequencies synchronized with the repeater units at locations of the detector units. The repeater units send the data to the repeater units using hop frequencies synchronized with the detector units. Such a system extensively avoids collisions between the transmissions by the base unit 112, the PMU 125 and the repeater units. In one embodiment, the detector units communicate with the repeater, base 112 or PMU 125 units in the 900 MHz band. This band provides good transmission through walls and other obstacles normally encountered in and around a structure of building. In one embodiment, the detector units communicate with the repeater, base 112 or PMU 125 units in bands above and / or below the 900 MHz band. In one embodiment, the detector units, repeater units, unit of Base 112 and / or PMU 125 listen to a radio frequency channel before transmitting on that channel or before starting transmission. If the channel is in use (for example, with another device such as another repeater unit, a cordless telephone, etc.) then the detector units, repeater units, base unit 112 and / or PMU 125 change to a different channel. In one embodiment, the detector units, repeater units, base unit 112 and / or 125 combine the frequency hop to listen to radio frequency channels for interference and using an algorithm to select a next channel for transmission that avoids interference. Thus, for example, in a mode, if a PMU 125 is instructed to send a communication, the PMU 125 will test (eg, listen to) the channel before transmission to avoid channels that are blocked, in use or stuck. Figure 2 is a block diagram of the detector unit 102. In the detector unit 102, one or more detectors 201 and a tranceptor 203 are provided to a controller 202. The controller 202 commonly provides power, data and control information. to the detector (s) 201 and the tranceptor 202. A power source 206 is provided to the controller 202. An optional tamper detector 205 is also provided to the controller 202. A reprocessing device (e.g. is tested to the controller 202. In one embodiment, an audio output device 209 is provided.In one embodiment, the detector 201 is configured as a plug module that can be replaced relatively easily. In one embodiment, a temperature detector 220 is provided to the controller 202. In one embodiment, the temperature detector 220 is configured to measure the ambient temperature. In one embodiment, the tranceptor 203 is based on a tranceptor chip TRF 6901 from Texas Instruments, Inc. In one embodiment, the controller 202 is a conventional programmable microcontroller. In one embodiment, the controller 202 is based on a field programmable gate array (FPGA), such as, for example, provided by Xilinx Corp. In one embodiment, the detector 201 includes an optoelectric smoke detector with a smoke chamber . In one embodiment, the detector 201 includes a thermistor. In one embodiment, the detector 201 includes a humidity detector. In one embodiment, the detector 201 includes a detector, such as, for example, a water level detector, a water temperature detector, a carbon monoxide detector, a humidity detector, a water flow detector, a natural gas detector, propane detector, etc. The controller 202 receives data from the detector 201. Some detectors 201 produce digital data. However, for many types of detectors 201, the detector data is analogous data. The analog data of the detector are converted to digital format by the controller 202. In a mode, the controller evaluates the data received from the detector (s) 201 and determines if the data is to be transmitted to the base unit 112. The detector unit 102 generally saves energy by not transmitting data within a normal interval. In one embodiment, the controller 202 evaluates the detector data by comparing the values of the data with a threshold value (e.g., a high threshold, a low threshold or a high-low threshold). If the data is outside the threshold (for example, above a high threshold, below a low threshold, outside a threshold of an internal interval or within a threshold of an external interval), then the data is considered to be they are anomalous and are transmitted to the base unit 112. In one embodiment, the data threshold is programmed into the controller 202. In one embodiment, the data threshold is programmed by the base unit 112 when sending instructions to the controller 202. In one embodiment, the controller 202 obtains data from the detector and transmits the data when it is commanded by the computer 113. In one embodiment, the tamper detector 205 is configured as a switch that detects the tampering / removal of the detector unit. 102. Figure 3 is a block diagram of the repeater unit 110. In the repeater unit 110, a first tranceptor 302 and a second tranceptor 302 are provided to a controller 302. The controlled r 303 commonly provides energy information, data to the transducers 302, 304. A power source 306 is provided to the controller 303. An optional tamper detector (not shown) is also provided to the controller 303. When data from the detector is relayed to the unit base 112, the controller 303 receives data from the first tranceptor 302 and provides the data to the second tranceptor 304. When instructions from the base unit 112 are relieved to a detector unit, the controller 303 receives data from the second tranceptor 304 and provides the data to the first tranceptor 302. In one embodiment, the controller 303 saves energy by turning off the tranceptors 302, 304 during periods when the controller 303 is not expected to receive data. The controller 303 also monitors the power source 306 and provides status information, such as, for example, self-diagnosis information and / or information about the health of the power source 306 to the base unit 112. In one embodiment, the controller 303 sends status information to base unit 112 at regular intervals. In one embodiment, the controller 303 sends status information to the base unit 112 when requested by the base unit 112. In one embodiment, the controller 303 sends status information to the base unit 112 when a defective condition is detected (for example, low battery). In one embodiment, the controller 303 includes a table or list of identification codes for the wireless detector units 102. The repeater 303 sends received packets of sent to the detector units 102 in the list. In one embodiment, the repeater 110 receives inputs for the list of detector units of the computer 113. In one embodiment, the controller 303 when a transmission of the detector units 102 is expected in the table of detector units and places the repeater 110 (e.g., tranceptors 302, 304) in a low power consumption mode when transistor transmissions are not expected in the list. In one embodiment, the controller 303 recalculates the times for the operation with low power consumption when a command is sent to change the reporting interval to one of the detector units 102 in the list (table) of detector units or when a New detector unit is added to the list (table) of detector units. Figure 4 is a block diagram of the base unit 112. In the base unit 112, a tranceptor 402 and a computer interface 404 are provided to a controller 403. The controller 303 commonly provides data and control information to the controllers. tranceptors 402 and the interface. The interface 404 is provided to a port on the monitoring computer 113. The interface 404 can be a standard computer data interface, such as, for example, Ethernet, wireless Ethernet, server port of security, main serial port of universal serial (USB), bluetooth, etc. Figure 5 shows an embodiment of a communication packet 500 used by the detector units, repeater units, base unit and PMU. The packet 500 a preamble portion 501, an address portion (or ID) 502, a data targe portion 503 and an integrity portion 504. In one embodiment, the integrity portion 504 includes a checksum. In one embodiment, detector units 102-106, repeater units 110-111 and base unit 112 communicate using packets such as packet 500. In one embodiment, packets 500 are transmitted using FHSS. In one embodiment, the data packets traveling between the detector unit 102, the repeater unit 111, the base unit 112 and the PMU 125 are encrypted. In one embodiment, the data packets traveling between the detector unit 102, the repeater unit 111, the base unit 112 and the PMU 125 are encrypted and an authentication code is provided in the data packet, in such a way that the detector unit 102, the repeater unit and / or the base unit 112 can verify the authenticity of the package. In one embodiment, the address portion 502 includes a first code and a second code. In one embodiment, repeater 111 only examines the first code for determine if the package should be sent. Thus, for example, the first code can be interpreted as a building code (or complex of buildings) and the second code interpreted as a subcode (for example, an apartment code, area code, etc.). A repeater that uses the first code to send, thus, sends packets that have a first specified code (for example, corresponding to the building or building complex of the repeater). Thus, it alleviates the need to program a list of detector units 102 to a repeater, since a group of detectors in a building will commonly have all the same first code but different second codes. A repeater configured here only needs to know the first code to send packets for any repeater in the building or building complex. However, this raises the possibility that two repeaters in the same building could try to send packets for the same detector unit 102. In one embodiment, each repeater waits for a programmed delay period before sending a packet. Thus producing the packet collision priority of the base unit (in the case of detector unit to base unit packets) and reducing the packet collision priority of the detector unit (in the case of unit packet of base to detector unit). In one mode, a delay period is programmed in each repeater. In one modality, delay periods are pre-programmed in the repeater units in the factory or in the installation. In one embodiment, a delay period is programmed in each repeater by the base unit 112. In one embodiment, a repeater randomly chooses a delay period. In one embodiment, a repeater randomly chooses a delay period for each packet sent. In one mode, the first code is at least 6 digits. In one mode, the second code is at least 5 digits. In one embodiment, the first code and the second code are programmed into each detector unit in the factory. In one embodiment, the first code and the second code are programmed when the detector unit is installed. In one embodiment, the base unit 112 may re-program the first code and / or the second code in a detector unit. In one embodiment, collisions are further avoided by configuring each repeater unit 111 to begin transmission on a different frequency channel. Thus, if two repeaters attempt to start the transmission at the same time, the repeaters will not interfere with each other because the transmissions will start on different channels (frequencies). Fig. 6 is a flow chart showing a mode of operation of the detector unit 102 where relatively continuous monitoring is provided. In Figure 6, an ignition or energization block 601 is followed by an initialization block 602. After initialization, the Detector unit 102 checks a defective condition (eg, activation of the tamper detector, low battery, internal fault, etc.) in a block 603. A decision block 604 checks the fault status. If a failure has occurred, then the process proceeds to a block 605, where the fault information is transmitted to the repeater 110 (after which, the process proceeds to a block 612); otherwise, the process proceeds to a block 606. In block 6060, the detector unit 102 takes a reading from the detector (s) 201. The detector data is subsequently evaluated in a block 607. If the data of the detector are abnormal, then the process proceeds to a transmission block 609, where the detector data is transmitted to the repeater 110 (after which, the process advances to a block 612); otherwise, the process proceeds to a finished time decision block 610. If the completed time period has not elapsed, the process subtracts the fault verification block 603; otherwise, the process advances to a transmission status block 611, where the normal status information re-elected to the repeater 110. In one embodiment, the normal status information transmitted is analogous to a "simple metallic sound" indicating that the detector unit 102 is functioning normally. After block 611, the process proceeds to block 612, where detector unit 102 momentarily listens instructions of the monitoring computer 113. If an instruction is received, then the detector unit 102 performs the instructions, otherwise, the process returns to the status verification block 603. In one embodiment, the tranceptor 203 is turned off or de-greenized usually. The controller 202 powers the tranceptor 203 during the execution of the blocks 605, 609, 611 and 612. The monitoring computer 112 can send instructions to the detector unit 102 to change the parameters used to evaluate the data used in block 607, the listening period used in block 612, etc. Relatively continuous monitoring, as shown in Figure 6, is appropriate for detector units that detect relatively high priority data (eg, smoke, fire, carbon monoxide, flammable gas, etc.). In contrast, continuous monitoring can be used for detectors that detect relatively lower priority data (for example, humidity, wetting, water uses, etc.). Figure 7 is a flow chart demonstrating an operation mode of the detector unit 102 where periodic monitoring is provided. In Figure 7, an ignition or energization block 701 is followed by an initialization block 702. After initialization, the detector unit 102 enters a sleep mode of low power consumption. Your failure occurs during sleep mode (for example, the tamper detector is activated), then the process enters an awakening block 704 followed by a block transmitting fault 705. But a failure occurs during the sleeping period, then when the specified sleeping period has expired, the process enters a block 706 in where the detector unit 102 takes a detector reading from the detector (s) 201. The detector data is subsequently sent to the monitoring computer 113 in a report block 707. After report, the detector unit 102 enters a listening block 708, wherein the detector unit 102 for a relatively short period of time instructs the monitoring computer 708. If an instruction is received, then the detector unit 102 performs the instructions, otherwise, the process returns to the sleep block 703. In one embodiment, the detector 201 and the tranceptor 203 are normally turned off or de-normalized. The controller 202 energizes the detector 201 during the execution of the block 706. The controller 202 energizes the tranceptor during the execution of the blocks 705, 707 and 708. The monitoring computer 113 may send instructions to the detector unit 102 to change the sleep period used in block 703, the listening period used in block 708, etc. In one embodiment, the detector unit transmits data where it detects until a handshake-type acknowledgment is received. So, instead of sleeping on no instructions or acknowledgments not received after transmission (for example, after block 613 or 709) the detector unit transmits its data and awaits an acknowledgment. The detector unit 102 continues to transmit data and awaits a receipt until an acknowledgment is received. In one embodiment, the detector unit accepts an acknowledgment from a repeater unit 111 and then it becomes the responsibility of the repeater unit 111 to ensure that the data is sent to the base unit 112. In one embodiment, the unit repeater 111 does not generate the acknowledgment, but rather sends an acknowledgment from the base unit 112 to the detector unit 102. The bidirectional communication ability of the detector unit 102 provides the ability for the base unit 112 to control the operation of the detector unit 102 and also provides the robust handshake communication capability between the detector unit 102 and the base unit 112. Without regard to the normal operation module of the detector unit 102 (for example, using the flow diagrams of Fig. 6, 7 or other modes) in one embodiment, the monitoring computer 113 can instruct the detector unit 102 to operate in a relatively continuous mode in where the detector repeatedly takes the readings from the detector and transmits the readings to the monitoring computer 113. Such mode may be used, for example when the detector unit 102 (or nearby detector unit) has detected a condition potentially dangerous (for example, smoke, rapid rise in temperature, etc.). Figure 8 shows the detector system used to detect water leaks. In one embodiment, the detector unit 102 includes a water level detector 803 and / or a water temperature sensor 804. The water level detector 803 and / or water temperature sensor 804 are placed for example in a tray under a water heater 801 in order to detect leaks of the water heater 801 and thereby prevent water damage of a leaking water heater. In one embodiment, a temperature sensor is also provided to provide the temperature near the water heater. The water temperature (temperature) detector can also be placed under a sink, in a floor drain, etc. In one embodiment, the safety of a leak is investigated by the detector unit 102 (or the monitoring computer 113) by measuring the elevation coloration at the water level. When placed near hot water tank 801, the severity of a leak can also be determined partly by measuring the temperature of the water. In one embodiment, a first water flow detector is placed in an inlet water line of hot water tank 801 and a second water detector is placed in an outlet water line for the hot water tank. Leakage in the tank can be detected when Observe the difference between the water that flows between the two detectors. In one embodiment, a remote shut-off valve 810 is provided, such that the monitoring system 100 can shut off the water supply to the water heater when a leak is detected. In one embodiment, the shut-off valve or shut-off valve is controlled by the detector unit 102. In one embodiment, the detector unit 102 receives instructions from the base unit 112 to shut off the water supply to the heater 801. In one embodiment, mode, the responsible party 120 sends instructions to the monitoring computer 113 instructing the monitoring computer 113 to send water supply shutdown instructions to the detector unit 102. Similarly, in one embodiment, the detector unit 102 controls a gas shut-off valve 811 for closing the gas supply to the water heater 801 and / or to an oven (not shown) when dangerous conditions are detected (such as, for example, gas leaks, carbon monoxide, etc.). In one embodiment, a gas detector 812 is provided to the detector unit 102. In one embodiment, the gas detector 812 measures the carbon monoxide. In one embodiment, the gas detector 812 measures the flammable gas, such as, for example, natural gas or propane. In one embodiment, an optional temperature sensor 818 is provided to measure the row temperature.

Using data from the temperature detector 818, the detector unit 102 reports conditions, such as, for example, excess battery temperature. Excess battery temperature is often indicative of poor heat transfer (and thus deficiency) in the water heater 818. In one embodiment, the optional temperature sensor 819 is provided to measure the water temperature in the water heater 810. Using the data of the temperature detector 819, the detector unit 102 reports conditions such as, for example, excess temperature or water temperature deficit in the water heater. In one embodiment, an optional current probe 821 is provided to measure the electrical current provided to a heating element 820 in an electric water heater. Using the data of the current probe 821, the detector unit 102 reports conditions, such as for example no current (a burned heating element 820 is indicated). An excess current condition often indicates that the heating element 820 is embedded with mineral deposits and needs to be replaced or cleaned. By measuring the current supplied to the water heater, the monitoring system can measure the amount of energy provided to the water heater and thus the cost of hot water and the efficiency of the water heater.

In one embodiment, the detector 803 includes a humidity detector. Using data from the humidity detector, the detector unit 102 reports humidity conditions, such as, for example, excess moisture which would indicate a water leakage, excessive condensation, etc. In one embodiment, the detector unit 102 is provided to a humidity detector (such as the detector 803) located near an air conditioning unit. Using data from the humidity detector, the detector unit 102 reports humidity conditions, such as, for example, excess moisture which would indicate a water leakage, excessive condensation, etc. In one embodiment, the detector 201 includes a humidity detector. The humidity detector can be placed under a sink or toilet (to detect plumbing leaks) or an attic space (to detect roof leaks). Excess moisture in a structure can cause severe problems such as mold, fungal growths, mildew and fungi, etc. (hereinafter referred to generically as mushrooms). In one embodiment, the detector 201 includes a humidity detector. The humidity detector can be placed under a sink, in an attic space, etc. To detect excess moisture (due to leaks, condensation, etc.). In one embodiment, the monitoring computer 113 compares the moisture measurements taken from different detector units in order to detect areas that have excess moisture. Thus, for example, the monitoring computer 113 may purchase moisture readings from a first detector unit 102 in a first attic area, with a humidity reading from a second detector unit 102 in a second area. For example, the monitoring computer can take humidity readings from a number of attic areas to establish a reference humidity reading and then compare the specific humidity readings of several detector units to determine if one or more of the units are measuring excess moisture. The monitoring computer 113 would indicate excess moisture areas for further investigation by maintenance personnel. In one embodiment, the monitoring computer 113 maintains a history of humidity readings for various detector units and indicates areas that show an unexpected increase in humidity for investigation by maintenance personnel. In one embodiment, the monitoring system 100 detects favorable conditions for fungi (e.g., mold, mildew, fungi, etc.) that grow by using a first moisture detector located in a first building area to produce first moisture data and a second humidity detector located in a second building area to produce second humidity data. The areas of the building can be for example, areas near a sink drain, accessory of plumbing, plumbing, attic areas, external walls, a ballast area in a boat, etc. The monitoring station 113 collects moisture readings from the first humidity detector and the second humidity detector and indicates favorable conditions for fungal growth by comparing the first moisture data and the second humidity data. In one embodiment, the monitoring station 113 establishes a reference humidity by comparing moisture readings of a plurality of moisture detectors and indicates possible conditions of fungal growths in the first area of the building when at least a portion of the first data of moisture exceed the reference humidity by a specified amount. In one embodiment, the monitoring station 113 establishes a reference humidity by comparing the humidity readings of a plurality of moisture detectors and indicates possible conditions of fungal growths in the first area of the building when at least a portion of the first moisture data exceeds the reference humidity by a specified percentage. In one embodiment, the monitoring station 113 establishes a reference humidity history by comparing the moisture readings of a plurality of moisture detectors and indicates possible fungal growth conditions in the first area of the building when at least a portion of the the first moisture data exceed the humidity history of reference for a specified amount in a specified period of time. In one embodiment, the monitoring station 113 establishes a reference humidity history by comparing the humidity readings of a plurality of moisture detectors over a period of time and indicates possible fungal growth conditions in the first area of the building when by at least a portion of the first moisture data exceeds the reference humidity by a specified percentage of a specified period of time. In one embodiment, the detector unit 102 transmits moisture data when it determines that the data data fail a threshold test. In one embodiment, the humidity threshold for the threshold test is provided to the detector unit 102 by the monitoring station 113. In one embodiment, the humidity threshold for the threshold test is calculated by the monitoring station from of a reference humidity set at the monitoring station. In one embodiment, the reference humidity is calculated at least in part as an average of moisture readings of a number of moisture detectors. In one embodiment, the reference humidity is calculated at least in part as an average in time of moisture readings of a number of humidity detectors. In one embodiment, the reference humidity is calculated at least in part as an average of the humidity readings time of a humidity detector. In a mode, the reference humidity is calculated at least in part as the lowest of a maximum moisture reading of an average of a number of moisture readings. In one embodiment, the detector unit 102 reports humidity readings in response to an interrogation by the monitoring station 113. In one embodiment, the detector unit 102 reports moisture readings at regular intervals. In one embodiment, a humidity range is provided to the detector unit 102 by the monitoring station 113. In one embodiment, the calculation of the conditions for fungal growth is to compare moisture readings of one or more moisture detectors with the reference humidity (or base). In one embodiment, the comparison is based on comparing moisture readings with a percentage (for example, commonly a percentage greater than 100%) of the reference value. In one embodiment, the comparison is based on comparing moisture readings with a specified delta value above the reference humidity. In one modality, the calculation of the probability of conditions for the growth of fungi is based on a history of the time of moisture readings, in such a way that the longer favorable conditions exist, the greater the probability of fungal growth. In one embodiment, relatively high humidity readings over a period of time indicate a Higher likelihood of fungal growth than relatively high moisture readings by short period time. In one embodiment, a relatively sudden increase in humidity compared to a baseline or reference humidity is reported by the monitoring station 113 as a possibility of a water leak. If the relatively high humidity continues over time then relatively high humidity is reported by the monitoring station 113 as it is possible for a water leak and / or a likely area to have fungal growth or water damage. Relatively more favorable temperatures for fungal growth increase the probability of fungal growth. In one embodiment, the temperature measurements of the building areas are also used in fungi growth probability calculations. In one embodiment, a threshold value for the fungal growth probability is calculated at least in part as a function of temperature, such that the temperature relatively more favorable to fungal growth results in a relatively lower threshold than relatively less favorable temperatures for fungal growth. In one embodiment, the calculation of the probability of fungal growth depends at least in part on temperature such that temperatures relatively more favorable to fungal growth indicate a relatively high probability Higher fungal growth than relatively less favorable temperatures for fungal growth. Thus, the one mode a maximum and / or minimum moisture threshold of a reference humidity is relatively lower for the temperature more favorable to fungal growth than the maximum and / or minimum humidity threshold above a reference humidity for relatively less favorable temperatures for fungal growth. In one embodiment, a water flow detector is provided to the detector unit 102. The detector unit 102 provides water flow data from the water flow detector and provides the water flow data to the monitoring computer 113. Then the monitoring computer 113 can calculate the use of water. Additionally, the monitoring computer can observe or monitor water leaks, for example by observing the flow of water when there should be little or no flow. So, for example, if the monitoring computer detects the use of water throughout the night, the monitoring computer can raise an alert that indicates that a possible water leak has occurred. In one embodiment, the detector 201 includes a water flow detector provided to the detector unit 102. The detector unit 102 obtains water flow data from the water flow detector and provides the water flow data to the computer of monitoring 113. Then the computer Monitoring can calculate the use of water. Additionally, the monitoring computer 113 can monitor water leaks, for example by observing the flow of water when there should be little or no flow. So, for example, if the monitoring computer detects the use of water throughout the night, the monitoring computer can raise an alert that indicates that a possible water leak has occurred. In one embodiment, the detector 201 includes a tamper detector of a fire extinguisher provided to the detector unit 102. The tamper detector of the fire extinguisher reports tampering or the use of a fire extinguisher. In one embodiment the tamper detector of the fire extinguisher reports that the fire extinguisher has been removed from its assembly, that a compartment of the fire extinguisher has been opened and / or that a safety lock on the fire extinguisher has been removed. In one embodiment, the detector unit 102 is configured as an adjustable threshold detector that calculates a threshold level. In one embodiment, the threshold is calculated as an average number of detector measurements. In one modality, the average value is a relatively long-term average. In one mode, the average is a time-weighted average, where the detector readings are used in the averaging process, weighted differently which readings of the less recent detector. In one embodiment, the most recent detector readings are weighted relatively more strongly than the less recent detector readings. In one embodiment, the most recent detector readings are weighted relatively less strongly than the less recent detector readings. The average is used to establish the threshold level. When the detector readings rise above the threshold level, the detector indicates a notification condition. In one embodiment, the detector indicates a notification condition when the detector readings rise above the threshold value for a specified period of time. In one embodiment, the detector indicates a notification condition when a statistical number of detector readings (e.g., 3 of 2, 5 of 3, 10 of 7, etc.) are above the threshold level. In one embodiment, the detector unit 102 various levels of alarm (eg, warning, alert, alarm) based on how far the threshold has risen from the detector reading. In one embodiment, the detector unit 102 calculates the notification level according to which both the detector readings have risen above the threshold and how quickly the detector readings have risen. For example, for the purpose of explanation, the level of readings and the speed of elevation can be quantified as low, medium and high The combination of detector reading level and elevation speed can be shown as a table, as shown in table 1. Table 1 provides examples and is provided by way of explanation, not limitation.

Table 1 That of ordinary skill in art will recognize that the level of notification N can be expressed as an equation N = f (t, v, r), where t is the threshold level, v is the detector reading and r is the speed of the reading of the detector. In one embodiment, the detector V reading and / or the elevation speed r are used in low pass in order to reduce the effects of noise in the detector reading. In one embodiment, the threshold is calculated by filtering steps of the detector readings using a filter with a relatively low cutoff frequency. A filter with a relatively low cutoff frequency produces a relatively long-term averaging effect. In one modality, separate thresholds are calculated for reading of the detector and for the lifting speed. In one embodiment, a calibration procedure process is provided when the detector unit 102 is energized. During the calibration period, the detector data values 201 are used to calculate the threshold value, but the detector does not calculate notifications, warnings, alarms, etc., until the calibration period is complete. In one embodiment, the detector unit 102 uses a fixed threshold value (eg, pre-programmed) to calculate notifications, warnings and alarms during the calibration period and then uses the adjustable threshold value once the calibration period is over . In one embodiment, the detector unit 102 determines that a detector failure 201 has occurred when the adjustable threshold value exceeds a maximum adjustable threshold value. In one embodiment, the detector unit 102 determines that a detector failure 201 has occurred when the adjustable threshold value falls below a minimum adjustable threshold value. The detector unit 102 can report such failure of the detector 201 to the base unit 112. In one embodiment, the detector unit 102 obtains a number of data readings from the detector 201 and calculates the threshold value as a weighted average using a weighting vector. The weighting vector weighs some Detector data readings relatively more than other detector data readings. In one embodiment, the detector unit 102 obtains a number of detector data readings from the detector unit 201 and filters the detector data readings and calculates the threshold value from the filtered detector data readings. In one embodiment, the detector unit 102 obtains a number of detector data readings from the detector unit 201 and filters the detector data readings and calculates the threshold value from the filtered detector data readings. In one embodiment, the detector unit applies a low pass filter. In one embodiment, the detector unit 201 uses a Kalman filter to remove unwanted components from the detector's data readings. In one embodiment, the detector unit 201 discards detector data readings that are "external" (these fall too much or too much below a normative value). In this way, the detector unit 102 can calculate the threshold value even in the presence of noise receiver data. In one embodiment, the detector unit 102 indicates a notification condition (e.g., alert, warning, alarm) when the threshold value too quickly. In one embodiment, the detector unit 102 indicates a notification condition (e.g., alert, warning, alarm) when the threshold value exceeds a specified maximum value. In one embodiment, the detector unit 102 indicates a notification condition (e.g., alert, warning, alarm) when the threshold value falls below a specified minimum value. In one embodiment, the detector unit 102 adjusts one or more operation parameter of the detector 201 according to the threshold value. Thus, for example, in the example of an optical smoke detector, the detector unit 201 can reduce the energy used to drive the LED in the optical smoke detector when the threshold value indicates that the optical smoke detector can be put on. in operation by a lower energy (for example, low ambient light conditions, clean detector, low air particle content condition, etc.). The detector unit 201 may increase the energy used to drive the LEDs when the threshold value indicates that the optical smoke detector should be operated at a higher power (eg, high ambient light, dirty detector, particle content). higher in the air, etc.). In one embodiment, an output of a heating and / or air conditioning (HVAC) heating system 350 is optionally provided to the detector unit 102 as shown in FIG. 2. In one embodiment, an output of the HVAC system 350 is optionally provided to repeater 110 as shown in figure 3 and / or monitoring system 113 as shown in figure 4. In this way, system 100 becomes aware of the operation of the HVAC system. When the HVAC system turns on or off, the airflow patterns in the room change and so the manner in which one or other materials (eg, flammable gases, toxic gases, etc.) change so well. Thus, in one embodiment, the threshold calculation takes into account the effects of airflow caused by the HVAC system. In one embodiment, an adaptive algorithm is used to allow the detector unit 102 (or monitoring system 113) "learn" how the HVAC system affects the detector readings and thus the detector unit 102 (or monitoring system 113) can adjust the compliance threshold level. In one embodiment, the threshold level is temporarily changed for a period of time (eg, raised or decreased) to avoid false alarms when the HVAC system is turned on or off. Once the airflow patterns in the room have been readjusted to the HVAC state, then the threshold level can be re-established for a desired system sensitivity. Thus, for example, in one embodiment, where an averaging or low pass filter type processes are used to set the threshold level, the threshold level is temporarily set to desensitize the detector unit 102 when the HVAC system is turned on or it turns off thus allowing the process of averaging or low pass filtering to establish a new threshold level. Once a new threshold level is established (or after a specified period of time), then the detector unit 102 returns to its normal sensitivity based on the new threshold level. In one embodiment, the detector 201 is configured as an infrared detector. In one embodiment, the detector 201 is configured as an infrared detector for measuring the temperature of objects within the division field of the detector 201. In one embodiment, the detector 201 is configured as an infrared detector. In one embodiment, the detector 201 is configured as an infrared detector to detect flames within the division field of the detector 201. In one embodiment, the detector 201 is configured as an infrared detector. In one embodiment, the detector 201 is configured as an image formation detector. In one embodiment, controller 202 is configured to detect flames by processing image data from the image formation detector. Figure 9 shows an example of a mode of a PMU. The PMU 125 includes a PMU housing 905 that covers electronic components (not shown). A 903 screen is attached to the front of the PMU 905 box. The PMU 905 box can also optionally have function keys PMU, such as, for example, ACUSE 907 button, OK 909 button, DIAGNOSTIC 911 VERIFICATION button, 913 CALL TO FIRE DEPARTMENT button, 915 CALL TO OCCUPANT button, ALERT TO OTHERS button 917, ON / OFF 919 SPEAK button 921 also as cursor driver 923 and volume controller 925. Screen 903 can be color or monochrome. The screen 903 may have backlight in order to allow viewing in the dark. Screen 903 can be any screen used to display an electronic signal, such as LCD, LED, color LCD, etc. The 903 screen can replace one or all of the buttons through the use of a contact screen. In one embodiment, the PMU 125 may use speech recognition in addition to or in place of the buttons. In one embodiment, the PMU 125 may use a combination of contact screen, buttons and speech recognition. In one mode, the function keys of the PMU can include a CUSE 907 button, an OK button 909, a 911 DATE CONTROL button, a 913 CALL TO FIRE DEPARTMENT button, a CALL TO OCCUPANT button 915, an ALERT TO OTHERS 917 button, an ON / OFF button 919 or a SPEAK button 921. The PMU function keys may also include other control keys and would be useful in a building or complex monitoring system. The PMU function keys can be located in Any convenient place in the box of the PMU 905, and can be of any color, shape, size or material. In addition, any combination, in which they include one or more PMU function keys may be incorporated into a PMU 125. The ACUSE button 907 instructs the PMU 125 that I sent a response to the monitoring computer 113 that the user has acknowledgment of receipt of the communication. The OK button 909 instructs the PMU 125 that I sent a response back to the monitoring system 113 that the user has investigated the situation has determined that the situation is a false alarm or is resolved. Button 913 of CALLING THE FIRE DEPARTMENT instructs the PMU 125 to send a response back to the monitoring computer 113 that instructs the monitoring computer 113 to call the local fire department and ask for help. In one embodiment, button 913 of CALLING TO THE FIRE DEPARTMENT can also instruct the PMU 125 to connect the user directly to the fire department through a secondary trance receiver 1313 configured to make regular telephone calls or cellular call. In one mode, button 913 of CALLING TO THE FIRE DEPARTMENT can instruct the PMU 125 that I sent a response to the monitoring computer 113 to call the fire department and to connect the PMU 125 to the fire department, in such a way that the user can speak directly to the fire department without the need for a secondary trancecptor 1313 in the PMU 125. In this mode, the monitoring computer 113 acts as a repeater between a telephone connection with the fire department and a radio frequency transmission or other transmission of the PMU 125. The button 915 of CALLING THE OCCUPANT can instruct the PMU 125 to send an instruction to the monitoring computer 113 to call the occupant or occupant of the unit in which the detector is located to see if the unit has occupants. In one mode, the 915 CALL OCCUPANT button instructs the monitoring computer to call the occupants of the unit and then connect the PMU 125 device directly to the owners via the 1309 tranceptor. In one mode, the button 915 CALL THE OCCUPANT instructs the PMU 125 to call the owner directly through the secondary tranceptor 1313, thereby allowing the PMU to speak directly with the owner. The ALERT TO OTHERS button 917 can instruct the PMU 125 to send an instruction to the monitoring computer 113 to contact other PMUs or other administration through other devices (eg, telephone, cell phone, facsimile, Internet , etc.) . In one embodiment, the ALERT OTHERS button 917 may also instruct the monitoring computer 113 to connect the user of the PMU to others (e.g., nearby apartments, other users of PMU, administration using other devices) that the monitoring computer contacts in order to discuss the situation. In one embodiment, the ALERT TO OTHERS button 917 can instruct the PMU 125 to directly contact another administration through the use of the secondary tranceptor 1313. The ON / OFF button 919 can instruct the PMU 125 to turn on when it has been turned off or alternatively turn off when it has been turned on in order to save energy. The SPEAK 921 button works in conjunction with a walkie talkie system that can be incorporated into the PMU 125. The TALK 919 button can either work in conjunction with the 1309 tranceptor or the secondary 1300 tranceptor. The SPEAK 921 button instructs the PMU 125 to send an electrical signal from the microphone 1303 to other local transceivers configured to receive the signal. The CURSOR CONTROLLER button 923 can instruct the PMU 125 to move the cursor on the screen either up or down or from side to side in order to navigate through every message sent from the monitoring computer 113 Furthermore, the CURSOR CONTROLLER button 923 may also allow the user to select certain information on the screen for additional use. The (the) button (en) 925 VOLUME can be used to adjust the volume of the PMU 125.

The DIAGNOSTIC VERIFICATION button 911 instructs the PMU 125 to send a message to the monitoring computer 113 to perform a diagnostic check on the detector system. When the diagnostic verification has been completed, the monitoring computer 113 then sends a communication to the PMU 125 containing the results of the diagnostic verification. One mode, the PMU 125 may require the user to enter a password or pass code to identify the user. One mode, the PMU 125 may require the user to enter a password or pass code to identify the user. In this way, multiple users can use the same PMU. In addition, the monitoring computer 113 can also be optionally used to keep track of the user's movement throughout the day, as well as to keep track of what the user is doing. In one modality, different tasks may require different levels of clearance. For example, a separate password or pass code may be required to program the detectors using the PMU 125. Although Figure 9 shows specific buttons, that of ordinary skill in the art will recognize that other buttons and / or a general keyboard may be provided. In one embodiment, the 903 screen is used to provide menu options and the 923 cursor driver is used to navigate between the menu items and select menu items. In one embodiment, the PMU 125 can be used to read the threshold level of several detectors and / or the readings of the detectors. In one embodiment, when a detector alert is sent to the PMU 125, the PMU 125 shows the detector threshold level and the detector reading level (and / or the number of detector readings that is above the detector level). threshold) . In one embodiment, the PMU 125 shows a map of other detectors of the detector's viticity that sends the alert and the readings of the detectors in the vinicity of the detector that sends the alert. In one embodiment, the user of the PMU 125 may select a detector and change the threshold value of the detector. Thus, for example, if the detector is giving false alerts, the user of the PMU 125 can adjust the threshold level of the detector to reduce the sensitivity of the detector.

Alternatively, if a first detector is in an apartment is sending an alert, the user of the PMU 125 can use the PMU 125 to change the threshold level (for example, increase the sensitivity) of other detectors in the apartment or in nearby apartments . In one modality the PMU 125 can show a map (for example, a contour map, colored map, etc.) of the detectors in the detector system showing sensitivity, threshold value, battery value, detector readings, etc. And thus provide the user with a global image of detector system. Figures 10-12 show examples of various communication modalities received by the PMU 125. Figure 10 graphically shows one modality of an alert message. The alert message is displayed on the 1003 screen of the PMU 125 and may include any relevant information about the alert. The relevant information may include any of the following: temperature or smoke elevation rate, apartment number or unit number, which rooms in the apartment the detector is located, the number of detectors that indicate an alert, the telephone number of the occupants, if others have been notified or not and / or others have acknowledged receipt of the notification, as well as any other relevant update information to determine the situation. Figure 11 shows graphically one modality of a warning communication. The warning message may be displayed on screen 1103 of PMU 125. The warning message may contain information such as a warning from the detector that a new battery is needed, a warning that has been tampered with with a detector, a warning that the heating, air conditioning or ventilation system needs maintenance or that a particular unit is not functioning properly, a warning that a water leak has been detected or any other relevant information to maintain a building or complex. Figure 12 graphically represents a communication in which a diagnostic check has been executed. The diagnostic verification can be shown on the 1203 screen of the PMU 125. The diagnostic verification communication may contain information such as the working status of each detector, if some maintenance is required in a detector (for example, it needs a new battery). or it is not working properly and needs repair or replacement). The diagnostic verification may also contain information about the repeaters, the ventilation and conditioning system, as well as diagnostic information of any other relevant system in the maintenance of a building or complex. Referring to Figures 10-12, the PMU 125 may indicate an alarm, warning, notification or other communication. For example, in one embodiment, an emergency alarm message may cause the PMU 125 to sound a loud buzzing, a series of sounds, a siren or any other noise designed to attract the user's attention. In one mode, the PMU 125 can vibrate or flash lights to catch the user's attention. In a mode, the PMU 125 may give an audible message such as "SMOKE DETECTED IN APARTMENT 33". Other types of communications, such as a warning, may be indicated in different ways, for example, a different type of audible sound. The volume of auditory alerts may change depending on the severity of the condition. Different colors of lights can flash or more or less lights can flash. In addition, the duration of the message indicators can be prolonged or shortened depending on the level of priority of the condition. The text displayed on the PMU 903 screen can also be configured at will to transport the necessary information to the building administration. For example, some or all of the words used on the screen may flash. Keywords can be highlighted. For example, the key information can be enlarged, highlighted, displayed in different colors or configured in another way to attract the attention of the user of the PMU. In one mode, the screen may be too small to display all the text of the message at the same time. In such cases, a cursor controller, such as the cursor controller 923, can be used to scroll through the entire message. You can also display graphics on the screen along with the text or as an instant screen that indicates the type of message that has been received before the user searches in the text of the message In one embodiment, the user may be required to press a function key, such as an ACUSE 907 button before the full text of the message is displayed on the screen. In addition, any advantageous changes to the text or graphic that can be displayed can be incorporated into the screen. Figure 13 is a block diagram of a PMU 125. In one embodiment, the PMU 125 includes a tranceptor 1309 for communication between the detector system and the 1311 controller. The 1311 controller commonly provides energy, data and control information to the tranceptor 1309. A power source 1315 is provided to controller 1311. Controller 1311 may also receive and / or optionally send electronic signals from a microphone 1303, user inputs 1305, a programming interface of detector 1301, an interface computer 1321, a location detector 1307 or a second tranceptor 1313. The microphone 1303 can be a microphone of any type that receives old noises and transmits a historical signal representing the auditory noise. The user inputs 1305 may include any button or user input device for communicating an instruction to the controller 1311. The computer interface 1321 is used to provide communication between the PMU 125 and a computer system (e.g., the monitoring computer 113). The interface of computer 1321 can be a standard computer data interface, such as Ethernet, wireless Ethernet, security server port, master serial port (USB), bluetooth, etc. A location detector 1307 can provide location details and / or movements of the PMU 125. The location detector 1307 can be any location or motion detection system, such as for example a global positioning system (GPS) or an accelerometer. to detect movement. A second transceiver 1313 may be provided for secondary communication channels. The second transceiver 1313 can communicate with any known communication network such as, for example, wireless Ethernet, cell phone or bluetooh. The programming interface of the detector 1301 can be used to enter or read programming information of the detector units, such as for example ID code, location code, update of programming elements, etc. In one embodiment, the programming interface of PMU 1301 can be designed to communicate all the detectors in a detector system at the same time. In one embodiment, the programming interface of the detector 1301 can be designed such that the PMU 125 can communicate with a selected detector or a group of detectors. For example, the detector interface 1301 can be designed in such a way that the PMU 125 must be closed to the detector in order to communicate with the detector. This can be carried out by designing the detector programming interface 1301 with optical communications, such as for example an infrared (IR) transmitter or designating the programming interface of the detector 601 with a wired communication, such as by wire connection directly. with a detector Figure 14 is a flow chart of a mode showing how the PMU 125 communicates with the detector system. The operation of the detector system in communication with the PMU 125 begins at block 1401 where the PMU 125 is energized. Then the PMU 125 advances to block 1403 where the PMU 125 advances through an initialization (eg, establishes communications with the monitoring computer 113, updates programming elements, etc.). Then the PMU 125 advances to block 1405 in which it listens for any communications from the monitoring computer 113. In block 1407, the PMU 125 decides whether the information has been received. If information has been received, the PMU 125 advances to block 1409, otherwise, the PMU 125 returns to block 1405 and listens for any communication. If information is received and the PMU 125 advances to block 1409, the PMU processes the information. In decision block 1411, the PMU 125 decides whether the information is an alert. If the information is an alert, then the PMU 125 advances to decision block 1419, from another In this manner, the PMU 125 proceeds to block 1413. In block 1413, the PMU 125 decides whether an abnormal condition communication or no diagnostic verification communication was required. If there is an abnormal condition or diagnostic check, the PMU 125 proceeds to block 1421. Otherwise, the PMU 125 advances to the decision block 1415. In the decision block 1415, the PMU 125 decides whether the user has entered an instruction or not . If there has been an instruction entered by the user then the PMU 125 moves to block 1417, otherwise, it returns to block 1405 and listens to the instruction. In block 1417, the PMU 125 performs the instruction or transmits the instructions back to the monitoring computer 113. Returning now to block 1419, in block 1419 the PMU 125 sounds an alarm or shows an alarm and then advances to the block of decision 1427, where it is searched to see if an acknowledgment has been received. If an acknowledgment has not been received, the PMU 125 proceeds to decision block 1433 where it shows to see if a timeout has elapsed. If a timeout has not elapsed, the PMU 125 moves back to block 1419 where it sounds the alarm and waits for an acknowledgment. If a timeout has elapsed, the PMU 125 returns to block 1405 where it listens to instructions from the monitoring computer 113. If in block 1405 an acknowledgment has been received, the PMU 125 advances to block 1429 where it transmits the acknowledgment and then advance to block 1423.

Returning now to block 1421, if it receives an abnormal condition or diagnostic condition, then the PMU 125 shows the abnormal condition or diagnostic verification message on the PMU screen 903 and then proceeds to block 1423. In block 1423, the PMU 125 awaits instructions. In decision block 1425, if an instruction is received, then PMU 125 advances to block 1417. Otherwise, PMU 125 advances to block 1431 where it is monitored in terms of movement as well. If there is no movement in the PMU 125, the PMU advances to block 1435 where it transmits a "no movement" alert to the monitoring computer and then returns to block 1405. If there has been movement, the PMU 125 returns to block 1423 and wait for instructions. Figure 15 is a graphic representation of alert priority responses by the monitoring computer 113. In one embodiment, different responses are assigned to different conditions. Priority levels may be based on the level of smoke, gas, water, etc., the amount of time that a detector has been pointing, the rate of smoke rise, temperature, gas, water, etc., the number of detectors that point or any other measurement that would be useful in determining the priority level of the situation. For example, as shown in block 1502, if a low priority condition occurs, the monitoring computer 113 sends information about the condition to the PMU 125 and no further action is taken by the monitoring computer 113 with respect to communication with the PMU 125. In a high priority condition, as shown in block 1503, the monitoring computer 113 sends information as to the condition to the PMU 125 and then wait for the acknowledgment and / or response. If the monitoring computer 113 does not receive an acknowledgment or response, it will attempt to contact another PMU or may attempt to contact the administration through other channels (eg, telephone, cell phone, fascimil, email, etc.). ). If the monitoring computer 113 receives an acknowledgment, but then receives a "no movement" alert from the PMU 125, the monitoring computer 113 will attempt to contact another PMU or may attempt to contact the administration through other channels. . In a high priority condition, as shown in block 1505, the monitoring computer 113 can immediately send information to multiple PMUs and can immediately attempt to contact the administration through other channels (eg, telephone, cell phone) , fascimil, email, etc.) and can wait a relatively short period for the acknowledgment and response before contacting the fire department directly. In a severe priority condition, as shown in block 1507, the monitoring computer can call the fire department directly and immediately.

You can immediately try to contact all the PMUs and all the other contacts in the administration. It will be understood by that of skill in art that the answers and conditions of Figure 15 are only an example and are not made by way of limitation. In addition, those skilled in the art will recognize that in one modality all conditions can be sent with the same priority level. In one mode, neighboring occupants will also be notified of a situation that arises. For example, in the case of a water leak, the occupants of units located under the unit indicates a water leak would be notified that a unit above them has a water leak so that they can take precautions. Occupants of other units located above, below, adjacent or near a unit with a detector that indicates a situation may also be notified, so that they can take appropriate precautions and / or provide more immediate assistance or assistance (eg, leakage of water, fire / smoke detected, carbon monoxide detected, etc.). In one embodiment, the monitoring computer includes a database indicating the relative locations of the various detector units 102, such that the monitoring computer 113 knows to which units to notify in the event of a situation occurring. So, for example, the computer monitoring can be programmed such that it knows units 201 and 101 are below unit 301 or that unit 303 is adjacent to unit 301 and unit 302 is passing through the lobby, etc. In one embodiment, the monitoring system 113 knows which detectors are in which apartments and the relative locations of several apartments (for example, which apartments are on top of each other, adjacent to each other, etc.). In one embodiment, the database of the monitoring system 113 includes information about detector locations in several apartments in relation to other apartments (for example, detector 1 in apartment 1 is in sector 3 opposite the wall in the apartment 2, etc.). It will be apparent to those skilled in the art that the invention is not limited to the details of the above illustrated embodiments and that the invention can be increased in other specific ways without departing from the spirit or essential attributes thereof; in addition, several omissions, substitutes and changes that can be made without departing from the spirit of the invention. For example, although specific embodiments are described in terms of the 900 MHz frequency band, that of ordinary skill in the art will recognize that frequency bands above and below the 900 MHz band can also be used.

SUMMARY OF THE INVENTION A detector system is described that provides an adjustable threshold level by the amount detected. The adjustable threshold allows the detector to adjust to environmental conditions, component aging and other operational variations while still providing a relatively sensitive detection capability for hazardous conditions. The adjustable threshold detector can operate for extended periods without maintenance or recalibration. A portable monitoring unit that works in communication with the detector system provides immediate communication of the conditions detected by the detectors. The portable monitoring unit allows the administration of the building or complex to be in communication with a detector system at all times without requiring that someone is physically present at a monitoring site. The portable monitoring unit can be equipped with an auditory device to alert management or a screen to display pertinent information regarding a situation that is presented in such a way that management can quickly identify and resolve the problem. In addition, the portable monitoring unit can also be equipped with function keys that allow the portable monitoring unit to send instructions back to the detector system. In one embodiment, the portable monitoring unit also includes a second transceiver for communications in a shortwave radio frequency or with a cell phone system.
