Description

The claimed technical solution as a utility model relates to the alarm industry, namely to alarms with an alarm system using radio communications.

The mobile alarm device is designed for automatic remote notification via GSM-mobile communication about the operation of sensors that monitor the parameters of the equipment or premises of industrial or household facilities. It can be - a house, a summer residence, an apartment, an office, a production room, a warehouse, a retail outlet, a garage, etc. As sensors can be used sensors of fire and burglar alarms or sensors of important technological parameters, exceeding which can lead to an emergency, for example - sensors of temperature, pressure, humidity, gas, mechanical vibration or other sensors.

The technical result of the application of the proposed technical solution is to expand the capabilities of alarms, increase the reliability, efficiency and ease of use, reduce the cost of their installation and maintenance.

The key problem of any alarm system is the transmission of an alarm signal from a triggered sensor to a control room or security control panel, i.e. link. Previously, cable communication channels were traditionally used, the laying of which, especially at considerable distances in a large city, significantly increased the cost of the entire alarm system. In cases of impossibility to lay cable channels, radio channels were used with the appropriate transceiver equipment, specially designed for specific operating conditions in terms of ensuring the required range, namely, they should take into account: allowed frequency channels, type of modulation, transmitter power, receiver sensitivity and others options. The big problem was protecting the radio channel from unauthorized access. At the same time, along with the high cost of the system, it was difficult to ensure high noise immunity of the alarm system in conditions, for example, of a large industrial area with saturated industrial radio interference.

The situation has changed markedly with the advent and widespread use of GSM cellular mobile communications, in which the above problems of radio channels have been successfully resolved (GSM - Global System of Mobile communication). High noise immunity and protection against unauthorized access are provided with almost unlimited range of cellular communications; its range is limited only by the coverage areas of the selected mobile operator.

Along with the main function, voice telephony - GSM-mobile communication also provides transmission of non-speech information, using the following technologies: SMS (Short Message Service) - for short text messages, GPRS (General Packet Radio Service) - for packet transmission of digital data. Recently, these technologies have been used in instrumentation systems for collecting information and control, including for alarms; at the same time, they are implemented using the corresponding devices of cellular modules, modems and terminals.

The most complete information about these cellular communication devices produced by various companies and their application can be found on the Internet on the website of Euro Mobile LLC (Euro Mobile, St. Petersburg) at:

http://www.euromobile.ru/documents.php

Summarizing the results of the analysis of this information, the following main features of these devices can be noted:

- Cellular modules are a compact core of a cellular modem, suitable for mounting on a board;

- Cellular modems are devices with interfaces (for example, RS-232) for communication with a computer;

- cellular terminals - complete fully functional devices, to

which can connect various sensors and actuators.

These cellular communication devices are universal and can be used to create remote telemetry systems, dispatching and monitoring, remote control, process parameters control, security systems or alarm systems. The use of cellular terminals, complex multi-channel devices is economically impractical for most alarm systems due to the excessive redundancy of their designs and capabilities.

To implement a specific alarm system based on a cellular module or cellular modem - in addition to one of these devices, additional devices, equipment, sensors, and software will be required. For example, to create a remote security system based on a cellular modem, you will need:

1) in a secure room -

- intrusion sensor (for example, a volumetric motion sensor infrared, ultrasonic or microwave type),

- board interface intrusion sensor with a microcontroller control,

- cellular modem,

- SIM card with a selected cellular tariff,

- external antenna

- uninterruptible power supply in case of power failure,

- patch blocks, wires, cables and fasteners;

All these devices must be located and mounted in a secure room;

2) in the control room -

- dispatcher computer,

- cellular modem,

- SIM card with a selected cellular tariff,

- external antenna

- uninterruptible power supply in case of power failure,

- patch blocks, wires, cables and fasteners.

In addition to all of the above, software will be required for programming the control microcontroller and for working with a dispatch computer, on the monitor of which information on the state of the system should be displayed, including alarming information when the intrusion sensor is triggered in a guarded room.

XITAL GSM is a cellular monitoring and control system developed by XITAL LLC. Detailed information about this system can be found on the company's website on the Internet at: http://www.ksytal.ru

On the basis of an ordinary cell phone, this company developed three cellular control and management kits for a different number of control zones covered: 4, 8 and 12.

The minimum system kit for 4 monitoring zones XITAL GSM-4 (PROTOTYPE - http://www.ksytal.ru/k 4 01.htm) is schematically shown in figure 1 and consists of:

a) base kit, including:

1 - XITAL controller,

2 - power adapter,

3 - reader of electronic keys Touch Memory,

4 - master key Touch Memory;

b) additional equipment purchased separately:

5 - electronic keys Touch Memory,

6 - cell phone,

7 - backup lead battery 12 V,

8 - control sensors

9 - actuators,

Controller 1 is mounted vertically on the wall of the guarded room, external devices are connected to it using appropriate cables, connectors and terminal blocks. To power the controller, adapter 2 is used, which is plugged into a 220 V power outlet and feeds the controller with a constant voltage of 21 V. For authorized access to the system, Touch Memory electronic key technology is used. Their reader 3 is mounted at the entrance door of the controlled room and is connected to the controller with a cable no longer than 15 meters. The reader has one LED indicator, by the nature of the glow of which you can determine the current mode of the system; in this case, three glow colors are used (red, green, yellow) and three glow modes - constant, blinking and shimmering from one color to another. For setting and removing the system from control, Touch Memory 5 electronic keys (up to 6 pieces) are used, for registration of which a master key 4 is used. Cell phone 6 is connected to the controller 1 with a short adapter cable and placed in a special controller pocket. One of the models is used as a cell phone: Siemens C35, M35, S35, C45, ME45, S45, MT50 or Siemens C55, M55, A60, C60, A62, A65, A75 depending on the type of controller connector. In the event of a power failure of 220 V, a lead battery of 7 by 12 Volts with a capacity of up to 7.2 A / h is used as a backup power source. At the bottom of controller 1 are two groups of terminal blocks. One group, consisting of 4 terminal blocks, is designed to connect various control sensors 8, which can be connected in series as a loop for one control zone, while the loop resistance should be within 2-5 kOhm; the maximum number of control zones is 4. The second group with relay outputs, consisting of 3 terminal blocks, is designed to connect various actuators 9 in an amount of up to 3 pieces. To control the actuators, normally open or closed relay contacts with a maximum current of 5A and an alternating current voltage of 220V are used. The built-in thermal sensor can ensure that relay No. 2 turns on when the controller temperature drops below 0 ° C and turns it off at a temperature above + 2 ° C.

Before operating the system, it is necessary to carry out appropriate installation work, observing the requirements for the installation of fire alarm systems. Then you need to make all the prescribed connections between the devices of the system and configure it. First, you must provide access to the system. To do this, according to the instructions, using the master key 4, the required number of Touch Memory 5 electronic keys is registered (up to 6 pieces). Further, in view of the fact that the XITAL GSM-4 monitoring and control system works on the basis of receiving and transmitting SMS messages, it is necessary to program the SIM card of the cell phone 6. To do this, follow the appropriate instructions to fill in the proposed control SMS command templates on the SIM card , a list of cell phone numbers (up to 10 numbers) for sending SMS messages and SMS messages about the activation of

or another sensor, a loop of sensors in one or another controlled area. It is possible to program 10 dialers to cell phone numbers with a direct Moscow number or to MGTS phone numbers with a voice message.

The work of the configured system is as follows. When leaving the controlled room by touching the Touch Memory reader with a registered electronic key, the preliminary setting “monitoring” is activated, which is indicated on the reader by a continuous green light with rare yellow indicator flashes. This starts the timer for 90 seconds. During this time, it is necessary to leave the controlled room. After this time, the “on control” mode is automatically activated, which is indicated by short yellow flashes of the indicator on the electronic key reader. In this mode, the system recharges the backup battery and cell phone battery as necessary, executes the commands contained in the incoming SMS messages, reports a 220 V mains failure and discharges the backup battery, and, most importantly, monitors the resistance of signal loops with sensors.

Typically, the sensors operate “open” and all sensors in the same zone are connected in series. In this case, when any sensor is triggered, the total loop resistance becomes infinitely large, which means a zone violation. A message about this with the number of the violated zone is sent to all phones on the mailing list. After 4 times the sensors of a zone are triggered and the corresponding SMS messages are sent, the violated zone is disconnected from the control and subsequent triggering of the sensors in this zone does not lead to the sending of messages. Control over this zone is restored only when the system is subsequently put under control.

Upon entering the controlled room, the entrance door sensor is activated, connected to zone No. 1, and the temporary “de-monitoring” mode is activated, while the indicator on the electronic key reader starts flashing red. After recognizing the code of the registered electronic key attached to the reader, the system switches to the “control taken” mode, which is accompanied by two short beeps and a change in the indicator blinking frequency. If the intruder enters through the door and the system is not taken out of control, then after some time delay will be sent messages about violation of zone No. 1. The delay time for sending messages is pre-programmed in the range from 1 to 99 seconds.

The disadvantages of the XITAL GSM-4 monitoring and control system related to the fact that it works on the basis of receiving and transmitting SMS messages are noted by the development company as system features and they are as follows.

System settings and the list of distribution phones are stored on the SIM card. Therefore, when changing the SIM card, it is necessary to re-create the list of phones and edit the settings as at the initial start of the system.

If you delete the primary phone number “recorded in the 10th cell” in the notebook, then with the subsequent initialization of the system, the mailing list will be replaced by empty templates. To restore the “default” settings, you must erase all SMS on the SIM card of the cell phone connected to the controller, and then restart the system by turning it off and then turning on the power of the controller again (to restart the system, the corresponding button is not provided !?).

For greater reliability and speed of SMS delivery - you must try to use one mobile operator to send and receive SMS. If you need to use the services of various operators, you must first make sure that there are appropriate agreements between them. You also need to practically check the stability of delivery and the absence of distortion in SMS messages.

When writing SMS commands, you must use only Latin text encoding (for example, an alarm message will look like "trevoga"). Otherwise, the sent SMS message may not be recognized by the controller as an executable command.

A common feature of the prototype and the claimed technical solution is the notification of the activation of control or security sensors via GSM-mobile cellular communication.

The differences of the proposed technical solution from the prototype are:

- the proposed alarm is intended only to alert triggered sensors; there is a control of the alarm itself, control of external devices is not provided;

- the cell phone, which is part of the alarm system, adapts to the control and management scheme;

- instead of SMS-messages, ordinary phone calls are used to control the alarm and alarm notification;

- instead of a programmable controller, a board with a control and control circuit is used on the basis of “hard” (non-programmable) logic implemented on microcircuits of digital CMOS series;

- control or protection sensors are integrated (combined) on one board with a control and management circuit;

- access to the alarm is not carried out using electronic keys such as Touch Memory, but by means of a normal call and the standard filter function of the telephone directory of the cellular telephone alarm;

- for power from a 220 V network, a standard cell phone power adapter is used;

- when using CMOS series of microcircuit microcircuits that consume current in units of microamperes for sensors, monitoring and control circuits, and using pulsed power supply for the sensors, not an external additional large-capacity lead battery is used as backup power in case of a 220 V power failure, but a battery cell phone;

- the entire alarm system is located in one compact unit, inside which an alarm board with two connectors is attached: for connecting a cell phone and a power adapter;

- on the front wall of the alarm unit there are LED indicators showing the current status of the alarm and its operation;

- settings for a cell phone alarm are carried out within the framework of standard functions provided for in its technical description;

- the cell phone is mounted on the rear wall of the alarm unit using a magnetic “suction cup”;

- there is no installation work to install an alarm in a controlled area; all you need to do is put the alarm unit on a flat horizontal surface and plug the power adapter into a 220 V power outlet.

The purpose of the claimed utility model is to expand the capabilities of alarms, increase the reliability, efficiency and ease of use, reduce the cost of their installation and maintenance.

The technical task was to create a compact, one-block alarm with GSM-mobile cellular communication, which does not require preliminary programming, without installation work for installation and is easy to manage.

The essence of the proposed technical solution lies in the fact that in one alarm unit, on one printed circuit board, a control and control circuit with rigid, non-programmable logic and a security and security sensor are combined, and -

alarm management and notification of sensors triggering are carried out using a GSM cell phone, adapted to the alarm and connected to it by cable. The sensor can be of any type - technological, security or fire. In the alarm system several sensors can be combined, for example, a security microwave motion sensor and a fire smoke detector; in this case we get a fire alarm.

Particular consideration is required to adapt the cell phone to the alarm system, to the logic of its operation. To do this, first consider the proposed logic of the alarm. Take a variant of a two-channel, for example, fire and security alarm system, which has two sensors: a security microwave motion sensor and a fire smoke sensor. Let us agree to call people who have their own mobile phones and access to work with alarms - “owner” and “trustee”; the person who illegally entered the guarded premises is a “violator”.

Consider a block diagram of a mobile fire alarm, presented in the drawing of figure 2, where:

10 - block alarm

11 - cell phone,

12 - AC adapter ~ 220 V,

13 - microwave motion sensor,

14 - smoke detector,

15 - trigger on-off alarm

16 - clock generator

17 is a control circuit,

18 - bus switching power sensors

19 - alarm trigger

20 - analog key for the button "quick call-1",

21 is an analog key for the button "quick call-2",

22 - an analog key for the end button (reset),

23 - voice messaging module,

24 - network indication LED ~ 220 V,

25 - node control the connection of a cell phone,

26 - LED indicating the disconnection of the cell phone,

27 - LED indicating the operation of the smoke sensor,

28 - LED indication of the operation of the microwave motion sensor,

29 - bus button "quick call-1"

30 - a common bus digital buttons of the phone,

31 - bus button "quick call-2",

32 - bus signal call-call,

33 - voice message bus,

34 - bus power cell phone

35 - bus charging battery cell phone

36 - common power bus, "ground".

To control the alarm unit 10, a normal call-call from the cell phone of the owner (or proxy) to the cell phone 11 (“alarm phone”) is used. When the alarm telephone is called, the appearance of the signal on the bus 32 is perceived by the trigger 15 as an “on” or “off” command, depending on the current alarm condition. For example, if before the call the alarm was in the “off” state, then the arrival of the call will be perceived as a “turn on” command and vice versa, i.e. a series of individual calls will be perceived according to the principle of operation of a two-stable trigger as a series of “on-off-on-off ...” commands. With such management, control over the appointment and execution of the team is important. It is carried out for some

analogies with most car alarms, when the execution of a command given from a car owner’s key fob is sounded by short beeps: one beep — the alarm turned on, two beeps — turned off. In the proposed alarm control during its control is carried out by listening to the calling phone the response of the telephone alarm. The following response signals were received: when the alarm is turned on, after one long beep of the call, short beeps of the end (reject) of the call sound; when the alarm is turned off - short hang-up beeps sound after three long beeps of a call. This order of the end of calls is provided by the control circuit 17, clocked from the generator 16; to end the call - briefly turns on the key 22, closing the bus 30 on a common bus, "ground".

When turned on, the alarm goes to the “security” mode not immediately, but after the preliminary “security” mode, which lasts 1 minute. This mode without alarm calls is provided as a test mode, in order to be able to visually check the operation of sensors 13 and 14 using the LED indicators 27 and 28. In this mode, the sensors are switched on via bus 18 and the alarm trigger 19 is disabled. After the end of the “guard” mode, the “guard” mode is automatically turned on - the alarm trigger 19 is unlocked.

Three long beeps of a call when the alarm is turned off are selected in order to be able to verify that the alarm is turned on (“check” mode for forgetful hosts); in this case, after two long beeps of the call, you need to disconnect the call of the alarm phone, the alarm will remain on. To turn off the alarm, you must wait for three long beeps to pass, after which short hang-up beeps will mean that the alarm is turned off. In this case, the control circuit 17 is blocked and the power to the sensors 13 and 14 is turned off.

When one of the alarm sensors 13 or 14 is triggered in the “guard” mode, without delay, in sequence with a minute interval, two ring-calls are made to the phones of the owner and authorized person. The first call to the owner is carried out by the control circuit 17 by means of a long (~ 4 second) switching on of the key 20; in this case, the bus 29 closes on the common bus of the digital buttons 30, causing the “quick call-1” button to be triggered, for which the host phone number is pre-assigned. This, as a rule, can be any digital button from “2” to “9”. Buttons of “quick call (dialing)” - a standard function of any cell phone, which can be found in the instructions for its use. In the same way, after 1 minute, measured by the control circuit 17, a second call occurs, a call to an authorized person. At the same time, when the tires 30 and 31 are closed for a long time through the key 21, the “quick call-2” button is activated, for which the telephone number of the authorized person is assigned. The second call also lasts 1 minute. In case of disturbing calls, the name of the calling subscriber (alarm telephone) is displayed on the screen of the called telephone as the name of the protected object, for example, “cottage”, “garage”, etc. When answering an alarm call - on the telephone of the owner (or authorized person), first a voice message is heard about the sensor that worked at the guarded object, for example, “intruder in the garage” or “smoke at the cottage”, after which you can listen to the room with the help of cell phone microphone (listening mode). Two voice messages are entered into the permanent memory of the voice message module 23, each of which is activated according to the operation of a particular sensor. After the end of the second call - the alarm automatically returns to the "guard" mode.

For sensors and alarm unit circuits, it is necessary to use micropower microcircuits of the CMOS series, consuming current in units of microamps. But, most importantly - pulse power is used to power the sensors with a large duty cycle of the supply pulses. These measures can significantly reduce the overall

alarm current consumption up to tenths of a milliampere. In this case, for signaling, you can take power + Upit from the power bus 34 of the cell phone, practically without loading it, since, for example, in standby mode, the cell phone consumption is usually several milliamps (3 ... 4 mA). Typically, the power bus 34 has a stabilized voltage of about +2.9 V, so it is necessary to use micropower low-voltage microcircuits having a power range of +2 V, for example, microcircuits of the series 74Нсххх, 74АСххх and the like. In addition, importantly, these microcircuits have high-impedance (tens and hundreds of MOhm) inputs and outputs (off) and do not create a noticeable additional load on the cell phone circuit when it is connected to the alarm unit and does not interfere with its operation.

The battery of a cell phone is the only power source for a mobile alarm in the event of a power failure of ~ 220 V. Depending on its condition, it will be able to provide an alarm for several days. To charge the battery, the power adapter 12 supplied with the cellphone is used, which is not connected directly to the cellphone, but via the signaling unit in order to monitor the voltage of ~ 220 V using the LED 24. In addition, if the cellphone is disconnected by for another reason, it is necessary to provide power to the connection control unit of the cellular telephone 25, which, using the red flashing LED 26, will inform about the disconnection of the cellular telephone. The selected type of alarm power provides automatic battery maintenance, which is included in the standard feature set of any cell phone.

Now, having determined the required logic of the alarm in different modes and having considered its block diagram, we will return to the issue of adapting a cell phone. In general, the essence of adaptation is as follows. Cell phone covers are removed to access the phone circuit board. To its nodal points necessary for the joint interaction of the telephone and the alarm unit, the conductors of a thin flat short cable are soldered. In our version, an 8-conductor flat cable is required. The second ends of these conductors are connected to the connector for the telephone to communicate with the alarm unit. To lead the cable out - a corresponding hole is made in the bottom of the plastic case of the phone. The phone is going again.

The search for the nodal points of the telephone circuitry on its printed circuit board, to which it is necessary to connect the conductors of the communication cable, does not cause special difficulties for a specialist electronics technician of average qualification. Where to look for these points? Firstly, the connection points of the buses 35 and 36 are easily determined by tracing the conductors from the corresponding contacts of the standard connector of the cell phone to connect the power adapter. Bus connection points 29, 30 and 31 are defined next to the contacts of the selected “quick call” buttons, which can be any two buttons with numbers from “2” to “9”. The connection point of the call signal bus 32 may be one of the conductors going to the speaker of the telephone. A point for voice bus 33 (for example, microphone amplifier input) can be found next to the microphone wires of the cell phone. The power bus of the cell phone 34 is determined using a tester. Firstly, the voltage on it should be about +2.9 V. Secondly, its load ability is determined; For this, a load resistor of the order of 300 Ohms is temporarily connected to it and to the common bus 36 - while the voltage on it +2.9 V should not noticeably decrease.

In the variant of a single-channel alarm, for example, only of a security type, with one microwave motion sensor, the following elements are excluded: smoke detector 14, voice message module 23 and bus 33. In a single-channel

the alarm option eliminates the need for a voice message, since all the necessary alarm information is contained in the name of the ringing cell phone alarm, which may be the name of the protected object; for example, displaying the name of the caller “summer cottage” on the screen of the receiving telephone of the owner (or proxy) - will mean the operation of a microwave motion sensor installed in the country - and, therefore, the intruder has penetrated the country.

A description of the design of the signaling unit and the general layout of the nodes of the claimed technical solution using the example of a two-channel signaling option is illustrated schematically in the drawings of Fig. 3 (rear view of the alarm unit) and Fig. 4 (type of alarm assembly), where:

37 - the back cover of the box of the alarm unit,

38 - printed circuit board of the alarm unit,

39 - socket connection cell phone

40 - connector for a 220 V power adapter,

41 - bodies settings or adjusting sensors

42 - suction magnet for attaching a cell phone,

43 - screws securing the back cover,

44 - cell phone

45 - cable with connector for connecting the phone to the alarm unit,

46 - box alarm unit,

47 - LED indicators

48 - holes for the smoke detector,

49 - AC adapter 220 V.

The printed circuit board of the alarm unit 38 is attached to the back cover of the box of the alarm unit 37 from the inside with the screws. The control and monitoring circuit of the alarm is located in its lower part. At the top of the board are alarm sensors. Two connectors are located at the bottom rear of the printed circuit board: 39 - for connecting a cell phone and 40 - for a 220 V power adapter. Above can be located the settings or adjustments of sensors 41 (potentiometers or microswitches) - for changing parameters of installed sensors, for example, their sensitivity or range of operation in specific conditions. To access the connectors and adjustments - the back cover has corresponding holes. On the outside of the back cover 37, a flat suction cup magnet 42 is attached (glued) to fix the cell phone 44, for which either a flat magnet or a strip of magnetic material is glued to the back wall of the phone. On the box of the alarm unit 46, LEDs 47 are placed to indicate the current alarm status. On the sides of the box (possibly on top) are openings 48 for the smoke detector. In the case of using a microwave motion sensor - the box must be plastic, transmitting microwave radiation from the sensor. When assembling the alarm - LED indicators 47 using conductors and two-pin connectors are connected to the printed circuit board; the back cover 37 with the printed circuit board 38 mounted thereon is attached to the box 46 using screws 43; a cellular telephone 44 with a flat cable 45 is connected to the unit through a connector 39 and is fixed to the unit with a suction magnet 42; power adapter 49 is connected to the alarm unit through connector 40.

Alarm settings before starting operation are as follows. To protect against unauthorized access to the alarm system, the standard “filter” function is used, for which only telephone numbers from which the alarm can be controlled are recorded in the telephone directory of the alarm telephone. On the alarm telephone, the two buttons of the “quick call” are selected (when the telephone is adapted) —the corresponding numbers of cellular phones are fixed (recorded), the calls of which must be made

when the alarm sensors are triggered, for example, the phone numbers of the owner and proxy. In turn, on these phones, the name of the alarm telephone number should be recorded in telephone directories as the name of the protected object, for example, “cottage”, “garage”, etc. To simplify and speed up the alarm management process - on the phones approved for management, select the “quick call” button of the alarm telephone and assign its number to it.

When choosing a location for installing alarms in a guarded room, you can be guided by the rules generally accepted when installing fire and security alarms with similar sensors. After setting the alarm, it is necessary to check the operation of its sensors in this particular place; if necessary, the sensors can be set using the appropriate controls (41).

The alarm phone is served in the same way as a regular cell phone. A SIM card is inserted into it, purchased together with the selected tariff of one or another mobile operator. Naturally, it is advisable to use a tariff without a monthly subscription for signaling. It should be borne in mind that some tariffs do not allow the use of paid services for 180 days - in this case, the tariff may be blocked by the mobile operator. To eliminate this, with prolonged inactivity of the alarm or in the absence of its operation (there are no intruders and no fires), it is necessary from time to time to conduct full alarm tests with the reception of alarm calls in the “listening” mode for at least 1 minute. During operation of the alarm system, it is necessary to monitor the status of the account (balance) of the cellular telephone alarm system and not to allow its blocking. If necessary, you can disconnect the cell phone from the alarm unit and use it like a regular cell phone (though with a “tail” below).

The mobile alarm device operates as follows. To turn on the alarm, the owner (authorized person) on his phone presses and holds the “quick call” button of the alarm phone. When the call goes, as can be seen on the phone screen - you need to listen to the ringing tone. After one long beep, short hang-up beeps will go - which means that the alarm has turned on in the “security” mode, which lasts 1 minute; upon its expiration, the “guard” mode is automatically activated. To turn off the alarm, you must also press and hold the “quick call” button of the alarm phone until the call goes. When listening after three long beeps, short hang-up beeps will go - that means the alarm has turned off. When the alarm sensor, for example, a security microwave motion sensor, is triggered in the “guard” mode, an alarm call is made to the first telephone within 1 minute, the number of which in the alarm telephone is assigned to the “quick call-1” button, for example, the telephone number of the host. The owner sees an alarm on the screen of his phone the name of the protected object, for example - "cottage". Answering a call, he can listen to the room where the sensor has triggered before 1 minute has passed. Then also within 1 minute there is an alarm call to the second telephone, the number of which in the alarm telephone is assigned to the “quick call-2” button, for example, the telephone number of the authorized person, which may be, for example, a neighbor in the country. He also sees the name of the guarded object on his phone, for example, “neighbor’s cottage,” and, answering a call, he can listen to the room where the sensor worked. After the second call, the alarm returns to the “guard” mode again. In case of multi-channel alarm, with several sensors, when answering an alarm call, first a voice message is heard about the sensor that worked, then, if necessary, you can listen to the room in which the specified sensor worked.
