Description

The present invention relates to an alarm device for detecting and alarming an abnormality such as a fire or a gas leak.

  2. Description of the Related Art Conventionally, residential alarms (hereinafter referred to as “residential alarms”) that detect and warn of fires in houses have become widespread.

  These home alarms operate using batteries as the power source and monitor the fire with smoke detectors or heat sensitive parts. When a fire is detected, a voice message such as "It is a fire is a fire." Is output and the indicator lamp is driven.

  The automatic test function regularly monitors sensor failure and battery voltage drop, and issues a failure alarm when a failure is detected. When the inspection switch is operated in the monitoring state, an inspection message corresponding to the state at that time is output.

  Furthermore, by reducing the current consumption for operating the circuit unit, the battery life exceeding 10 years is guaranteed even with a battery power source.

JP 2007-094719 A

  However, in such a conventional home alarm, the operation with a battery life exceeding 10 years is guaranteed using a limited battery capacity, so that the current consumption should be reduced as much as possible. In particular, the functions such as alarm output and display are set to the minimum necessary configuration.

  For example, a fire alarm when a fire is detected is set to emit an alarm sound at a predetermined volume or higher. However, since the current consumption increases as the volume is increased, the predetermined alarm is required for alarm recognition. Current consumption is suppressed by setting the minimum necessary volume that satisfies the volume or by intermittently outputting the output pause period. However, it is desirable to increase the volume of alarms that are installed in places where there are no people at all times, such as hallways and stairs, compared to those installed in places where people are present, such as living rooms and bedrooms. If the alarm volume is increased, the battery life cannot be guaranteed.

  Also, as a fire alarm, a voice message such as “It is a fire is a fire” is repeatedly output from the speaker at a predetermined volume or more. However, because the alarm sound output by the voice message from the speaker increases current consumption, A buzzer with low current consumption is also considered. However, it is expected that the buzzer sound alone as an alarm sound may be inappropriate depending on the installation location, but there is a problem that changing the voice message affects the battery life.

  Such a problem is not only an alarm sound, but if you try to expand the basic fire monitoring function of the home alarm, the current consumption will always increase, and if you expand and use the various functions of the home alarm Has become a major obstacle.

SUMMARY OF THE INVENTION An object of the present invention is to provide an alarm device that enables function expansion with an increase in current consumption without impairing the battery life for fire monitoring.

  According to the present invention, in addition to a main battery that supplies power to a load that performs an original function of an alarm device that performs abnormality monitoring such as a fire including a sensor unit, a notification unit, and an alarm processing unit, the main battery is connected via a backflow prevention element. Since a detachable auxiliary battery that supplies power in parallel to the load is provided, the consumption current increased by the auxiliary battery even if a function expansion accompanied by an increase in the current consumption, such as an alarm sound enhancement or an alarm by voice message, is added. As a result, it has the great advantage that the appropriate expansion of functions can be freely constructed without affecting the life of the main battery with respect to the basic function of abnormality monitoring by the main battery. It is possible to open up various ways to use the residential alarms and various alarms that are widely used. That is, various options can be provided according to the user's application.

  In addition, since the auxiliary battery is connected to the main battery power line via a backflow prevention element, when the main battery approaches the battery life and the battery voltage decreases, the auxiliary battery supplies power in parallel to the load of the main battery. The battery life can be further extended by backing up the main battery with an auxiliary battery.

  In addition, since the auxiliary battery is provided on the premise of replacement by the user, even if the auxiliary battery runs out of battery due to the extended function, it can be easily handled by replacing the auxiliary battery by the user. Since the driving power of the extended function is supplied from the auxiliary battery, even if the extended function is operated, the life of the main battery related to the monitoring alarm operation which is a basic function is not affected.

In addition, by detecting the voltage drop when the auxiliary battery approaches the battery life and stopping the operation of the extended function unit itself, it is possible to prevent the main battery from being consumed by the operation of the extended function unit without backup by the auxiliary battery. The battery life of the battery can be guaranteed.

  FIG. 1 is an explanatory view showing an embodiment of a residential alarm (house fire alarm) according to the present invention, with a perspective view shown in FIG. 1 (A) and an auxiliary battery removed in FIG. 1 (B). A front view is shown.

  In FIG. 1, the housing of the residential alarm 10 according to this embodiment includes a cover 12 and a main body 14. In the center of the cover 12, a smoke detecting section 16 having a smoke inlet is opened around it so that a fire is detected when smoke from the fire reaches a predetermined concentration.

An acoustic hole 18 is provided on the lower left side of the smoke detector 16 provided in the cover 12, and a buzzer or a speaker is built in behind this so that an alarm sound or a voice message can be output. An alarm stop switch 20 is provided below the smoke detector 16. The alarm stop switch 20 also has a function as an inspection switch for instructing a functional inspection of the house alarm. For example, when the alarm stop switch 20 is operated at the time of a fire alarm, the alarm is stopped, and when the alarm stop switch 20 is operated in a normal state, its own function check is performed and the result is notified.

  The alarm stop switch 20 includes a switch cover formed of a translucent member and a tact switch (not shown) arranged inside the switch cover. In the vicinity of the tact switch inside the switch cover, as shown by a dotted line, an LED 22 for displaying an alarm is arranged. When the LED 22 is lit, the LED 22 is lit through the switch cover portion of the alarm stop switch 20. It is understood from the outside.

The rear upper portion of the main body 14 is provided with mounting hook 15 may be screwed and bis on the wall of the room to be installed, installing a home alarm 10 to the wall by passing the mounting hook 15 bis.

  In addition to the construction of the house alarm 10 as described above, in the present embodiment, the battery cover 26 is provided inside the cover 12 with an auxiliary battery that is detachably provided on the top of the cover 12 for supplying operating power to the extended function. It is stored in.

  FIG. 1B shows a state in which the battery cover 26 at the top of the cover 12 is removed and disassembled. An auxiliary battery storage portion 28 opened forward and upward is formed in the upper portion of the cover 12, and two battery storage holes 28 a having contact terminals are formed in the auxiliary battery storage portion 28. As shown in the right side of the battery storage hole 28a, two auxiliary batteries 30 using button batteries are stored, and the battery cover 26 is slid from above with the auxiliary battery 30 stored. By fitting, the auxiliary battery 30 is closed with the battery cover 26 closed as shown in FIG. In this housed state, the auxiliary battery 30 is connected to the main body via each part of the auxiliary battery part 76 and supplies power as shown in FIG. The two auxiliary batteries 30 illustrated here may be connected in series or in parallel depending on the circuit to which power is supplied, but FIG. 2 shows only one auxiliary battery 30.

  In addition, in the residential alarm 10 of FIG. 1, although the residential alarm which detects the smoke by the fire provided with the smoke detection part 16 is taken as an example, the thermistor etc. which detect the heat by a fire other than this are taken. House alarms and alarms with temperature detectors, house alarms and alarms that detect other physical phenomena associated with fires, alarms that detect gas leaks in addition to fires, intruders, earthquakes, and other abnormalities Various types of alarm devices and combinations of these alarm devices are also included in the scope of the present invention.

  FIG. 2 is a block diagram showing an embodiment of a circuit configuration in the residential alarm of FIG. In FIG. 2, the residential alarm 10 includes a processor 60 known as a one-chip CPU. For the processor 60, a sensor unit 62, a notification unit 64, an operation unit 66, a transfer unit 68, a memory 70, and a main battery. 34 is provided.

  The sensor 62 is provided with a smoke detector 16 that detects smoke and outputs a smoke detection signal. In addition to the smoke detector 16, the sensor unit 3462 may be provided with a temperature detection element such as a thermistor for detecting a temperature due to a fire, and various elements for detecting other physical phenomenon changes accompanying the fire.

  The notification unit 64 is provided with a speaker 65 that outputs an alarm sound and an LED 22 that performs display associated with the alarm. The speaker 65 outputs a voice message and an alarm sound from a voice synthesis circuit (not shown) via the voice amplifier 82. The LED 22 displays an abnormality such as a fire by blinking, blinking, lighting, or the like.

  The operation unit 66 is provided with an alarm stop switch 20. The alarm stop switch 20 is effective as an alarm stop switch only when an alarm sound is output from the notification unit 64 through the speaker 65 or a display accompanying the alarm is performed through the LED 22. If the alarm stop switch 20 is operated while the alarm sound is being output, the alarm sound is stopped. At this time, if the fire detection continues, the display associated with the alarm is lit or blinked.

  On the other hand, the alarm stop switch 20 functions as an inspection switch in a normal monitoring state in which no fire alarm is performed. When the alarm stop switch 20 is pressed in this state, a predetermined inspection operation is performed, and the inspection result is output from the speaker 65 of the notification unit 64. A voice message or the like indicating is output. Voice messages such as inspection results are output with the gain of the voice amplifier 82 set to G1.

  The memory 70 stores unique information such as the serial number of the house alarm, various setting information necessary for operation, inspection result data, and the like, and is read out and processed by the processor 60 as necessary.

  The processor 60 is provided with an alarm processing unit 72 including an event detection unit 73 and an event processing unit 74 as functions realized by executing the program. The event detection unit 73 detects an event such as a fire detection by the sensor unit 62, an alarm stop by the operation unit 66, a fire recovery in which the fire detection of the sensor unit 62 disappears.

  When the event detection unit 73 detects a fire, the event processing unit 74 outputs an alarm sound from the speaker 65 and drives the LED 22 to display the fire.

  More specifically, when the event processing unit 74 detects a fire in the event detection unit 73 based on the smoke detection signal from the smoke detection unit 16 provided in the sensor unit 62, an alarm sound such as “ “It ’s a fire, it ’s a fire” is repeatedly output, and the LED 22 blinks, for example, to display an alarm.

  Further, if the interlocking destination home alarm device or interlocking device is connected to the signal line or wireless communication, the transfer unit 68 transmits a transfer signal indicating a fire alarm to the other home alarm devices. The event processing unit 74 stops the alarm sound from the speaker 65 when the event detection unit 73 detects an alarm stop operation of the alarm stop switch 20 provided in the operation unit 66 during the output of the fire alarm sound. The display of the LED 22 is stopped.

  In addition, when the event processing unit 74 detects a failure of the sensor unit 62 or a low battery failure approaching battery exhaustion due to a drop in the battery voltage of the main battery 34 in the event detection unit 73, the event processing unit 74 notifies the notification corresponding to the detected failure event. 64.

  For example, when a sensor failure is detected, a process of continuously outputting “pick, failure” from the speaker 65 of the notification unit 64 a predetermined number of times and then outputting “pick, failure” a predetermined number of times every predetermined time. repeat. When the inspection operation by the alarm stop switch 20 is detected in the normal monitoring state, for example, “pick, please contact the dealer” is output once based on the sensor failure.

  As for the main battery 34 being out of battery, when the event detecting unit 73 first detects a decrease in out-of-battery battery capacity, for example, the speaker 65 outputs “beep, out of battery” a predetermined number of times, and thereafter at regular intervals. Repeat the process of outputting “beep, battery exhausted” a predetermined number of times. In addition, when an inspection operation by the alarm stop switch 20 is detected in a state where the battery of the main battery 34 is detected, “beep, battery is out of place. Replace the main battery” is output once.

  In addition to such basic functions for fire monitoring and alarming of the house alarm device 10, in the present embodiment, an auxiliary battery unit 76 and an extended function unit for changing and controlling the alarm sound are provided. The auxiliary battery unit 76 is provided with the auxiliary battery 30, and the positive side of the auxiliary battery 30 is connected to the positive-side power supply line via diodes 78 and 79 as backflow prevention elements. Therefore, the processor 60, the sensor unit 62, the notification unit 64, the operation unit 66, the transfer unit 68, and the memory 70 that are loads of the main battery 34 are supplied with parallel power supply by the main battery 34 and the auxiliary battery 30. .

  Further, the positive side of the auxiliary battery 30 is pulled down and connected to the input port of the processor 60 by a signal line 80. Based on the voltage from the positive signal line 80 of the auxiliary battery 30, the processor 60 determines whether or not the auxiliary battery 30 is attached, and changes the alarm volume when the power supply voltage from the auxiliary battery 30 is detected. Enable the extended function. As control for changing the alarm sound, for example, an auxiliary alarm sound may be added or the output pattern may be changed. In this embodiment, the original alarm volume is increased.

  That is, in this embodiment as an extended function unit that operates by parallel power supply by the auxiliary battery 30, the sound amplifier 82 and the gain control unit 84 are provided in the notification unit 64, and the volume output from the speaker 65 is changed by gain control. It is possible.

  The gain control unit 84 sets a gain G1 necessary for outputting a warning sound with a predetermined volume, but as an extended function, the gain control unit 84 is controlled to change to a gain G2 that is a higher value than the gain G1 that outputs a warning sound with a larger volume. Can do.

  Along with the extended function for increasing the alarm volume, the processor 60 is provided with an extended function processing unit 85 as a function executed by a program. The extended function processing unit 85 includes a volume control unit in this embodiment. 86 is provided.

Volume control unit 86, for example, operates the power supply at the start by the main battery 34, if the read ports to the positive power supply voltage is input from the auxiliary battery 30, the power supply voltage of the auxiliary battery 30 enabled is obtained In this case, the alarm volume control provided as an extended function is enabled, and the volume control unit 86 changes the gain of the audio amplifier 82 by the gain control unit 84 from G1 to G2 so far, and the audio signal with the increased gain G2 is output. An alarm sound is output from the speaker 56 by amplification.

  In this state, when a fire event is detected by the event detection unit 73 from the smoke detection signal of the sensor unit 62 and the voice signal of the voice message is output by the event processing unit 74, the loudspeaker 56 is greatly amplified by the amplification of the voice signal by the gain G2. A warning sound is output.

  Although the current consumption of the audio amplifier 82 and the speaker 65 increases due to the output of a large alarm sound due to such an extended function, since it operates by receiving a parallel power supply from the main battery 34 and the auxiliary battery 30, it relates to the basic function. For example, a battery life of 10 years can be guaranteed.

  Further, when the battery voltage of the main battery 34 is lowered, power is supplied from the auxiliary battery 30 to the power line of the main battery 34, so that the battery failure of the main battery 34 is compensated by the power supply from the auxiliary battery 30. Even if the main battery 34 drops below a predetermined voltage before the battery runs out during long-term use, if the battery capacity of the auxiliary battery 30 is sufficient at that time, the auxiliary battery 30 moves toward the main battery 34 side. The battery life can be substantially extended with the parallel power supply.

  That is, since the capacity detection (battery voltage reduction) of the main battery 34 is monitored by the event detection unit 73 and a fault alarm is output when the capacity is reduced, the user is informed that it is time to replace the main battery 34. On the other hand, even if it is not exchanged until the monitoring and alarm function of the home alarm device 10 with the main battery 34 is lost after that, if the capacity of the auxiliary battery remains over a predetermined amount, the operation can continue. The effect of extending the grace period until the exchange is obtained.

  Further, the extended function for increasing the alarm volume does not need to guarantee the battery life of 10 years by the original main battery 34 of the home alarm device 10, and the auxiliary battery 30 has the battery cover 26 as shown in the embodiment of FIG. For example, a button battery or the like that can be easily replaced by the user is removed. When the auxiliary battery 30 runs out of battery, the battery cover 26 is removed and the auxiliary battery 30 is replaced with a new one. Thus, it is possible to easily cope with a battery exhaustion of the auxiliary battery 30.

  Further, the extended function processing unit 85 of the processor 60 can monitor whether the auxiliary battery 30 has run out of battery. That is, the battery voltage on the plus side of the auxiliary battery 30 is input to a specific port of the processor 60 through the signal line 80, and the processor 60 assists by periodically reading the port to which the battery voltage of the auxiliary battery 30 is input. It is possible to recognize the battery voltage of the battery 30 and output an alarm indicating that the auxiliary battery 30 has run out when the voltage drops below a predetermined voltage. For example, the alarm of battery exhaustion of the auxiliary battery 30 may be output by using the speaker 65 of the notification unit 64, for example, “Beep, battery of auxiliary battery is exhausted” or the like.

Further, the extended function unit 85 has a function of increasing the volume of the alarm sound by the volume control unit 86 when the battery exhaustion in which the power supply voltage of the auxiliary battery falls below a predetermined voltage is detected. The function of changing the gain of 82 to G2 is stopped, and the gain of the audio amplifier 82 is held at G1. As a result, the auxiliary battery 30 approaches the battery life, and the consumption of the main battery 34 due to the operation of the extended function in the absence of backup by the auxiliary battery 30 is prevented, and the battery life of the main battery is guaranteed.

  FIG. 3 is a flow chart showing the fire monitoring process by the residence guard of FIG. In FIG. 3, in the fire monitoring process, initialization and self-diagnosis process are executed as the main battery 34 is turned on in step S1, and if there is no abnormality, the process proceeds to step S2 to determine whether or not the extended function is detected. .

  At this time, if the auxiliary battery 30 is stored as shown in FIG. 2, the battery voltage of the auxiliary battery 30 with respect to the processor 60 is read from the specific port to detect the extended function, and the process proceeds to step S3, where the extended function is provided. Enable alarm volume control.

  Subsequently, when the smoke detection signal output from the sensor unit 62 in step S4 exceeds a predetermined fire level, a fire alarm event is detected and the process proceeds to step S5, where an alarm sound from the speaker 65 and the LED 22 is lit, flashing, or blinking. A fire alarm is output when

  At this time, if the extended function of the alarm sound control is enabled in step S3, that is, if the attachment of the auxiliary battery 30 is detected, as an output of the fire alarm in step S5, the notification unit is instructed by an instruction from the processor 60. The setting gain of the gain control unit 84 provided at 64 is changed from G1 to G2 so far, and an audio signal is amplified by the audio amplifier 82 with the gain G2 to output an alarm message with a large volume from the speaker 65.

  Subsequently, in step S6, it is determined whether or not there is a fire recovery event in which the smoke detection signal from the sensor unit 62 decreases and the fire disappears. When a fire recovery event is detected, the fire alarm is stopped in step S7.

  If no fire recovery event is detected during the fire alarm, it is determined in step S8 whether or not there is an alarm stop event by operating the alarm stop switch 20, and if an alarm stop event is determined, an alarm is generated in step S9. If it is determined that it is, the process proceeds to step S10, and the fire alarm is stopped.

  On the other hand, when the alarm stop event by the alarm stop switch 20 is determined in the normal monitoring state where the fire alarm is not performed, it is determined in step S9 that the alarm is not in progress and the process proceeds to step S11. In this case, the alarm stop switch 20 Since the operation is an operation as an inspection switch, a predetermined inspection process is executed and an inspection message indicating the result is output.

  That is, if the result is normal, for example, an inspection message for confirming an alarm sound such as “Beep, normal” is output. If a sensor failure is detected, the message “Beep, failure. Please contact your dealer” is output. If the battery of the main battery 34 is detected as being out of power, the message “Beep, battery is out of service. Replace the main battery” is output once. Further, when the auxiliary battery 30 has an inspection function, when a voltage drop of the auxiliary battery is detected, “pick, auxiliary battery is exhausted” is output once.

  FIG. 4 is an explanatory view showing another embodiment of a residential alarm according to the present invention in which an auxiliary battery is detachably provided on the back side. FIG. 4 (A) is a front view, and FIG. The figure is shown. In FIG. 4, the house guard 10 of the present embodiment is basically the same as the embodiment of FIG. 1, but the auxiliary battery 30 is screwed at the center lower side as shown in the rear view of FIG. As in the embodiment of FIG. 1, an auxiliary battery 30 using two button batteries is housed inside a battery cover 36 fixed by, for example.

  A battery cover 32 is provided above the battery cover 36, and a main battery 34 using a lithium battery, an alkaline battery, or the like is accommodated therein. The main battery 34 is pre-installed at the factory manufacturing stage of the home alarm device 10, whereas the auxiliary battery 30 is removed when the user or the user wants to use the extended function by removing the battery cover 36 and the auxiliary battery 30. By storing the alarm volume can be increased.

  FIG. 5 is an explanatory view showing another embodiment of a residential alarm according to the present invention in which an extended function unit is detachably provided. FIG. 5 (A) is a perspective view, and FIG. 5 (B) is an extended function unit. The front view which took out and showed is shown.

  In FIG. 5, the basic configuration of the residential alarm 10 is the same as that of the embodiment of FIG. 1, but in this embodiment, a detachable auxiliary battery unit 38 is provided on the top of the cover 12. As shown in the right side of FIG. 5B, the auxiliary battery unit 38 stores two auxiliary batteries 30 using button batteries, and the auxiliary battery 30 is stored by the user as needed. It is possible to exchange. Moreover, the connector 40 is provided in the lower part of the unit, and the connector 40 is electrically connected to the internal circuit of the home alarm device 10 by being fitted into a unit housing provided in the upper portion of the cover 12 of the home alarm device 10. That is, the auxiliary battery 30 is connected to the internal circuit of the home alarm device 10.

  The auxiliary battery unit 38 includes, for example, a circuit including a diode 78 as a backflow prevention element for supplying the power of the auxiliary battery 30 shown in the circuit diagram of the home alarm device 10 in FIG. A circuit for supplying 30 positive battery voltage detection signals to the processor 60 through a signal line 80 is integrated.

  In this way, by providing the auxiliary battery unit 38 that is detachable from the home alarm device 10, when the user selects the extended function, the auxiliary battery unit 38 shown in the figure is mounted, and for users who do not need the extended function. In this case, the auxiliary battery unit 38 may be attached without inserting the auxiliary battery 30.

  FIG. 6 is an explanatory view showing another embodiment of a residential alarm according to the present invention provided with an auxiliary battery unit for storing a large-capacity large battery. FIG. 6 (A) is an exploded view of the auxiliary battery unit. 6B is a front view, and FIG. 6C is a side view.

  In FIG. 6, the house guard 10 of the present embodiment is basically the same as that of the embodiment of FIG. 1, but here, a detachable auxiliary battery unit 42 is provided on the top of the cover 12. As shown in the right side, the auxiliary battery unit 42 is provided with a battery housing portion 46 having a cylindrical hole in the upper portion of the unit main body 44.

  In the present embodiment, for example, two AA batteries can be stored in the battery storage unit 46. Thus, since the battery storage unit 46 can store a large-sized dry battery, a sufficient battery as an auxiliary battery can be obtained as compared with the case where a button battery is used as the auxiliary battery 30 shown in the embodiment of FIGS. Capacity can be secured easily.

  Two switches 50 are provided in the center of the unit main body 44. Further, a connector 48 is provided at the lower part of the unit main body 44 so that it can be electrically connected to an internal circuit when the extended function unit 42 is attached to the home alarm device 10.

  The switch 50 provided in the unit main body 44 can be used to give an appropriate instruction operation to the extended function, such as selection operation, start operation, and stop operation of the extended function provided to the auxiliary battery unit 42. For example, when an alarm volume control is provided as an extended function, the alarm volume is switched between high and low by turning on and off with the right switch 50, and the sound quality of the voice message (switching between male and female voices) is switched with the left switch 50. 7) Operations such as switching the contents are possible.

  FIG. 7 is a block diagram showing another embodiment of a residential alarm circuit according to the present invention provided with an extended function for changing an alarm sound from a beep sound to a voice message.

  In FIG. 7, the circuit configuration on the processor 60 side and the configuration of the auxiliary battery unit 76 serving as the load of the main battery 34 in the home alarm device 10 are the same as those in the embodiment of FIG. Instead of the volume control unit 86, an audio conversion unit 88 is provided.

  The sound conversion unit 88 is configured to emit a beep sound through the speaker 65 of the notification unit 64 as a basic alarm function by the event processing unit 74, but as a beep function as an extended function when it is determined that the auxiliary battery 30 is attached. Change the alarm by sound to output by voice message sound.

  For example, if the alarm sound due to a beep sound is “pip pip pip pip”, for example, it is changed to a voice message sound such as “pip pip pip, fire. When such an extended function is provided, the current consumption is increased by the output by the voice message sound changed by the extended function, compared to the current consumed by the beep sound before the extended function is provided.

  In the present embodiment, the auxiliary battery 30 provided in the auxiliary battery unit 76 is connected to the main battery 34 side via the diode 78 as a backflow prevention element in response to the increase in current consumption due to such an extended function. Therefore, even if the current consumption increases due to the extended function by changing from the buzzer sound to the voice message sound, the increase in the current consumption should be compensated by the parallel power supply by the auxiliary battery 30. Even if the current consumption increases, the battery life of the main battery 34 is not affected.

Further, when the extended function unit 85 detects a battery exhaustion in which the power supply voltage of the auxiliary battery drops below a predetermined voltage, the extended function unit 85 stops the function of making the alarm sound by the voice conversion unit 88 a voice message and outputs a beep sound. The main battery 34 is prevented from being consumed by the operation of the extended function in the state where there is no backup by the battery 30, and the battery life of the main battery is guaranteed.

  FIG. 8 is a flow chart showing the fire monitoring process by the residence guard of FIG. In FIG. 8, when the power supply by the main battery 34 in the home alarm device 10 is started, initialization and self-diagnosis are performed in step S21, and then whether or not the extended function is detected based on the mounting of the auxiliary battery 30 is determined in step S22. When the extended function is determined, the process proceeds to step S23, and the extended process by the voice conversion unit 88 that changes the warning beep sound to the warning message sound is validated.

  Thus, if the setting of the extended processing function is completed in step S23, fire monitoring processing is performed in steps S24 to S31. The processes in steps S24 to S31 are the same as steps S4 to S11 in FIG.

  The extended function processing unit 85 including the volume control unit 86 and the audio conversion unit 88 shown in the above embodiment may be mounted on the auxiliary battery unit 76 side. Also in this case, the extended function processing unit 82 operates by supplying power from the auxiliary battery, and is connected to the processor 60 through a signal line. When the connection of the auxiliary battery is detected, the processor 60 controls the extended function processing unit 85 via the signal line, and also controls the audio amplifier 82, the gain control unit 84, and the speaker 65. Of course, the gain controller 84 can also be incorporated on the auxiliary battery side.

  In the above embodiment, the alarm volume is controlled as an extended function and the buzzer sound is changed to the voice message sound. However, the present invention is not limited to this, and the house alarm is basically used. The present invention can be similarly applied to appropriate extended functions that can be added to the processing functions that the user has.

  For example, in the case of a residential alarm or the like that does not require a display associated with an alarm, the display using the LED 22 can be an extended function.

  Examples of other extended functions include, for example, a function for converting commercial power to a predetermined DC power source and supplying it to the house alarm device 10, and a microphone to record alarm data and audio data output during various announcements. Function, lighting function, clock function, human body detection using human sensor, brightness detection using lighting sensor, environmental detection such as temperature and humidity, earthquake detection by seismic sensor, gas detection by gas sensor, For example, a function of monitoring an abnormality other than the main monitoring target of the alarm device, such as detecting and processing a fire using a different type of fire phenomenon sensor different from the monitoring target of the sensor unit 62, can be considered.

  Of course, the functions described here are examples of extended functions, and the present invention is not limited to these.

  In the above embodiment, an alarm device is used as an example when it can be interlocked with another resident alarm device by wired connection from the transfer unit. However, by providing a wireless communication unit, another resident alarm device can be connected wirelessly. It can also be applied to alarm devices that are linked to alarm devices.

  Further, the above embodiment is not limited to residential use, but can be applied to various types of alarm devices such as buildings and offices.

  Moreover, although said embodiment has taken the case where a sensor part and a process part are integrally provided in the alarm device as an example, as another embodiment, the alarm device which made the sensor part and the process part separate may be sufficient. .

The present invention is not limited to the above-described embodiments, includes appropriate modifications that do not impair the objects and advantages thereof, and is not limited by the numerical values shown in the above-described embodiments.
