Description

The present invention relates to an alarm device that is installed in a general house or the like and detects an abnormality such as a fire or a gas leak by driving a battery.

  Conventionally, alarm devices that detect and warn of abnormalities such as fires and gas leaks in homes have become widespread. Of these, residential disaster alarms are referred to as residential alarms.

  In such a house alarm, a sensor unit and an alarm unit are integrated in the house alarm, and when a fire is detected by the sensor unit, a fire alarm is output from the alarm unit by voice message, etc. Because it is possible to perform fire monitoring and alarm with a single resident alarm without requiring a receiving facility, the installation is simple and inexpensive, and it is widely spread along with the obligatory installation in ordinary houses.

  On the other hand, by communicating between multiple home alarms, if a fire alarm is given by any home alarm, another type of home alarm system is also proposed, in which other home alarms also give an alarm. Has been.

  In such a home alarm system, when a fire is detected by the home alarm, the home alarm that detected the fire, for example, sends a voice message saying “Wu Wu fire alarm has been activated”. I am trying to output. When an alarm is issued by the house alarm, the alarm is stopped by operating an alarm stop switch provided in the house alarm.

  On the other hand, when the alarm stop switch is operated in the normal monitoring state, the inspection is executed and the inspection result is output by a voice message.

  In recent years, as a result of efforts to reduce the power consumption of residential alarms, a long battery life of, for example, 10 years or more is guaranteed, and no battery replacement is required during that period. When the battery life is approached after a long period of use, and a decrease in battery voltage is detected, a battery warning notice (hereinafter referred to as a battery dead warning) is periodically output to prompt battery replacement.

  After the start of the battery exhaustion alarm output (after the battery voltage drop is detected), it is sufficient that the intermittent battery exhaustion alarm output can be continued for a predetermined time (for example, 72 hours) or more, that is, within the predetermined time. There is no problem if the battery is replaced. Generally, since it is designed so that a normal monitoring operation can be performed during this period, the battery exhaustion alarm is not a highly urgent alarm like a fire alarm.

  Therefore, as a battery exhaustion alarm, a conventional fire alarm that outputs a battery exhaustion alarm from a speaker after a lapse of a predetermined time after detecting a decrease in battery voltage to avoid as much as possible an acoustic alarm output from night to early morning, which is a bedtime period. When the alarm device (Patent Document 1) or the battery voltage is lower than a predetermined voltage, the battery lamp is turned on or blinked in order to notify the battery decrease, and the switch is operated in this state. A battery-type alarm device (Patent Document 2) is known that outputs a voice message including contents for prompting replacement from a speaker.

In addition, if a battery voltage drop is detected while the user is absent for a long time, a battery low alarm is output continuously for as long as possible with the minimum power consumption, and the user returns home. In addition, an alarm device has also been proposed in which a battery is surely noticed and a battery operation is known by a switch operation (Patent Document 3).

  By the way, in such a conventional house alarm, when a battery low is detected, a battery exhaustion alarm is output, and thereafter, a battery exhaustion alarm is output periodically or when a switch is operated. As described above, the threshold voltage for detecting the voltage drop is set so that a sufficient margin time can be secured from the time when the battery warning is detected to the time when the operation of the residential alarm is actually stopped.

  However, the battery exhaustion alarm only repeats the same alarm, such as an alarm message such as “Beep battery exhausted” and the temporary lighting of the indicator lamp, and the battery voltage further decreases after the user notices it. I don't know how much time I can afford to stop the house alarm, and even if I ask a dealer to replace the battery, I have an uneasy situation that I do not know when it will run out . In addition, the fact that the house alarm becomes inoperable as a result of the delay in battery replacement and there is a period during which the fire cannot be monitored has a serious safety problem.

An object of the present invention is to provide an alarm device capable of outputting more detailed information as necessary when a battery exhaustion alarm is issued.

The present invention
A battery for supplying power;
A sensor unit that detects a physical phenomenon in the monitoring area and outputs a detection signal;
A notification unit for outputting an abnormality alarm;
An operation unit for instructing predetermined processing from the outside;
An alarm processing unit that outputs an abnormality alarm from the notification unit when an abnormality is detected from the detection signal of the sensor unit; and
An alarm stop unit that stops an abnormality alarm from the notification unit when an operation of the operation unit is detected during output of an abnormality alarm by the alarm processing unit;
In a house alarm equipped with
After detecting a battery voltage drop and outputting a battery exhaustion alarm by the notification unit, a first battery exhaustion alarm is output when an operation of the operation unit is detected, and a first battery exhaustion alarm is detected when a push operation by the operation unit is detected. A battery voltage drop monitoring unit that outputs a second battery exhaustion alarm with detailed information added thereto is provided.

  Here, when the battery voltage drop monitoring unit detects a long press operation of the operation unit as the push operation, the battery voltage drop monitoring unit outputs a second battery exhaustion alarm from the notification unit.

The battery voltage drop monitoring unit outputs a message that prompts for battery exhaustion and battery replacement as the first battery voltage drop alarm, and the remaining operation is possible for the message that prompts battery replacement and battery replacement as the second battery voltage drop alarm. Output a message with time added.

According to the present invention, after a battery voltage drop is detected and a battery exhaustion alarm is given, a user who knows that the battery has run out by a periodic battery exhaustion alarm or the like can perform a switch operation, for example, a normal operation. For example, you can check the battery deadline warning and the battery deadline warning that prompts the user to replace the battery. Attached information and detailed information such as the contents indicating the elapsed time from the start or detection of the battery exhaustion alarm, etc. are output.For example, even if a battery exhaustion alarm is issued, the operation of the alarm stops and stops functioning It is possible to know how much time is available, and even when a dealer or the like is requested to respond to a battery exhaustion, it is possible to take appropriate measures with the aim. In addition, even if the power supply of the house alarm device is turned off as a result, the user can clearly recognize the fact, which leads to alerts such as fire prevention.

  FIG. 1 is an explanatory view showing the appearance of a home alarm device according to the present invention. FIG. 1 (A) shows a front view and FIG. 1 (B) shows a side view.

  In FIG. 1, the housing of the residential alarm 10 according to this embodiment includes a cover 12 and a main body 14. A plurality of smoke inlets are opened in the center of the cover 12, and a smoke detector 16 is disposed inside the cover 12, 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 and a speaker are built in behind this so that an alarm sound and a voice message can be output. A multifunction switch 20 is provided below the smoke detector 16.

  The multi-function switch 20 functions as an alarm stop switch, an inspection switch, or a battery exhaustion alarm switch according to the operating state of the home alarm device 10 when the switch is operated.

  For example, when the multifunction switch 20 is operated at the time of a fire alarm of the residential alarm 10, it functions as an alarm stop switch that stops the alarm. Further, when the multifunction switch 20 is operated in the normal monitoring state of the home alarm device 10, it functions as an inspection switch that executes a predetermined inspection operation and outputs an inspection result by a voice message.

  Further, for example, when the multi-function switch 20 is operated after a battery voltage drop is detected and a battery exhaustion alarm is given, it functions as a battery exhaustion alarm switch and a battery exhaustion alarm is output. In other words, if the battery voltage is low, the home alarm automatically outputs a periodic battery warning by display and / or sounding, and when the user operates the multifunction switch in that state, However, it outputs a battery exhaustion alarm by display and / or pronunciation. In this case, in the present embodiment, the first operation of the multi-function switch 20 outputs a first battery warning that prompts battery replacement and a second battery warning that prompts battery replacement. Is output. Here, in the present embodiment, for example, the second battery exhaustion alarm is a content in which attached information and detailed information such as the remaining operable time are added to the first battery exhaustion alarm.

  In another embodiment, the first battery warning is output in the normal operation, and the second battery warning is output in the push operation such as a long press. Here, in the present embodiment, for example, the second battery exhaustion alarm is a content in which attached information and detailed information are added to the first battery exhaustion alarm. The details of this battery warning will be clarified later.

    Thus, the multi-function switch 20 functions as an alarm stop switch, an inspection switch, or a battery exhaustion alarm switch according to the operation state of the home alarm device 10 at that time, and it is necessary to provide a plurality of switches according to the function. In addition, the user can easily make a confirmation based on a necessary operation without being aware of switch selection or unnecessary pushing operation.

  The multifunction switch 20 includes a switch cover formed of a translucent member and a tact switch (not shown) disposed inside the switch cover. In the vicinity of the tact switch inside the switch cover, an LED 22 for displaying an alarm is arranged as indicated by a dotted line. When the LED 22 is turned on, blinks, or blinks, the operation light is transmitted through the switch cover portion of the multifunction switch 20. Thus, the operating state of the LED 22 can be seen from the outside.

  A mounting hook 15 having an insertion hole in the substantially central portion is provided at the upper part on the back side of the main body 14, and a screw or the like is screwed into the wall surface of the room to be installed, and the screw is passed through the insertion hole of the mounting hook 15. The residential alarm 10 can be fixedly installed on the wall surface or the like.

  In the residential alarm 10 of FIG. 1, a smoke detector 16 is provided as an example, and a residential alarm that detects smoke due to fire is taken as an example. However, the temperature of a thermistor or the like that detects heat due to fire is also taken as an example. House alarms with detection elements, house alarms that detect other physical phenomena associated with fires, alarms that detect gas leaks in addition to fires, various alarms that detect intruders, earthquakes, and other abnormalities, etc. An alarm device formed by combining these is also included in the scope of the present invention.

  FIG. 2 is a block diagram showing an embodiment of the residential alarm shown in FIG. In FIG. 2, the residential alarm 10 includes a processor 24 known as a one-chip CPU. For the processor 24, a sensor unit 26, a notification unit 28, an operation unit 30, a memory 34, a transfer circuit unit 36, and a battery power source. 38 is provided.

  The sensor unit 26 includes a smoke detector 16 that detects smoke and outputs a signal. As described above, the sensor unit 26 may be provided with a temperature detecting element such as a thermistor for detecting the temperature due to a fire, and various elements for detecting other physical phenomenon changes accompanying the fire, instead of the smoke detecting unit 16.

  The notification unit 28 is provided with a speaker 44 that outputs an alarm sound and an LED 22 that displays an alarm. The speaker 44 outputs a voice message and an alarm sound from a voice synthesis circuit unit (not shown) via an amplification unit (not shown). The LED 22 displays an abnormality such as a fire by blinking, blinking, or lighting. A buzzer or the like may be used instead of the speaker 44. Further, instead of the LED 22, a two-color LED, a liquid crystal display, or the like may be provided. Of course, an LED and a liquid crystal display may be provided together.

  The operation unit 30 is provided with a multi-function switch 20. The multi-function switch 20 functions as either an alarm stop switch, an inspection switch, or a battery exhaustion alarm switch according to the operation state of the home alarm device 10 at that time.

  The memory 34 stores a battery voltage drop flag 40 and a remaining operable time 42. The battery voltage drop flag 40 is set when the processor 24 detects a battery voltage drop due to consumption of the battery power supply 38 (battery capacity drop), and the multifunction switch 20 is operated based on the set state of the battery voltage drop flag 40. Sometimes, when this flag is set, a first battery exhaustion alarm or a second battery exhaustion alarm is output according to the order of operation or the manner of operation.

  The remaining operable time 42 stores in advance the standard estimated time from when the battery voltage drop is detected (for example, when the battery voltage drop flag is set) until the operation of the house alarm stops. When the battery voltage drop monitoring unit 50 detects a battery voltage drop, it reads the remaining operable time 42 stored in the memory 34 as an initial value, and sequentially subtracts the elapsed time thereafter, thereby allowing the remaining operation. The time can be obtained in real time. Further, after that, it is also possible to check the voltage value of the battery power supply in a timely manner, set the corresponding operable time 42 (reset of the initial value), and sequentially subtract the elapsed time from that point.

  When the fire is detected, the transfer circuit unit 36 outputs a transfer signal to other devices to perform a linked operation when a fire is detected, and the output transfer signal is, for example, a no-voltage contact signal.

  The battery power supply 38 uses, for example, a lithium battery or an alkaline dry battery having a predetermined number of cells, and as a battery capacity, for example, guarantees a battery life of 10 years by reducing the power consumption of the entire circuit unit in the residential alarm 10. Yes.

  The processor 24 is provided with functions of an alarm processing unit 46, an alarm stop unit 48, a battery voltage drop monitoring unit 50, and an inspection processing unit 52 as functions realized by executing the program.

  The alarm processing unit 46 outputs an alarm sound indicating a fire from the speaker 44 when the fire is detected based on the smoke detection signal from the sensor unit 26 and drives the LED 22 to display an alarm.

  Specifically, the alarm processing unit 46 compares the smoke detection signal of the smoke detector 16 provided in the sensor unit 26 with a predetermined threshold value, and detects and detects a fire when the smoke detection signal level exceeds the threshold value. In some cases, an alarm sound such as “Woo Woo is a fire” is repeatedly output from the speaker 44 of the notification unit 28, and the LED 22 is turned on to display an alarm.

  When the alarm stop unit 48 detects the operation of the multi-function switch 20 during the output of the fire alarm, the alarm stop unit 48 stops the output of the fire alarm by the voice message from the speaker 44 and the alarm display of the LED 22. At this time, the alarm display by the LED 22 may be stopped after continuing for a predetermined time.

  The battery voltage drop monitoring unit 52 reads the power supply voltage of the battery power supply 40 at a predetermined measurement time interval T1, for example, T1 = 4 time intervals by A / D conversion via a battery voltage detection unit (not shown), and outputs a predetermined threshold voltage. Compared with Vth1, a battery voltage drop is detected when the voltage is lower than the threshold voltage, and when the battery voltage drop is continuously detected for a predetermined number of times, the battery voltage drop is confirmed (determination detection). The lowering flag 42 is set.

  The battery low alarm from the notification unit 28 by the battery voltage drop monitoring unit 52 outputs, for example, three times “battery dead” when the battery voltage drop is determined, and simultaneously flashes the LED 22 in synchronization with the alarm sound. . After that, based on the set state of the battery voltage drop flag 42, for example, a warning sound such as “Battery is dead” is output three times as a regular ringing every hour.

Further, when the battery voltage drop monitoring unit 52 detects an operation of the multi-function switch 20 in a state where the battery voltage drop flag 42 is set, the battery voltage drop monitoring unit 52 outputs a battery exhaustion alarm from the speaker 44 of the notification unit 28. There are the following two battery exhaustion alarms based on the operation of the multifunction switch 20.
(1) The first operation of the multi-function switch 20 outputs a first battery warning that prompts the user to run out and replace the battery, and the second and subsequent operations output a second battery warning.
(2) The first battery exhaust warning that prompts battery exhaustion and battery replacement by normal operation of the multi-function switch 20 is output, and the second battery exhaust alarm is output by push operation such as long press.
Here, the second battery exhaustion alarm can be a content in which detailed information such as the remaining operable time and attached information are added to the first battery exhaustion alarm, or contents indicating only the attached / detailed information.

FIG. 3 shows a list of examples of the notification contents of the battery exhaustion alarm corresponding to the operation of the multi-function switch in the set state of the battery voltage drop flag. When the first operation or normal operation of the multi-function switch 20 is detected in a low battery voltage state, the first battery exhaustion alarm is displayed as “Contact your dealer.”
Is output from the speaker 44 as a voice message.

In addition, when the second or subsequent operation of the multi-function switch 20 or a separate push operation such as a long press is detected, the second battery exhaustion alarm is displayed. Please contact your dealer. ○ It's time. ''
Is output from the speaker 44 as a voice message.

  FIG. 4 is a graph conceptually showing the battery voltage drop characteristic due to the battery capacity drop of the battery power supply 38 used in the present embodiment. In FIG. 4, the horizontal axis represents the operating time under standard conditions, and the vertical axis represents the voltage of the battery power source.

  The battery capacity is reduced due to the power consumption of the battery power source due to the use of the home ward, and the voltage of the battery power source is also lowered accordingly. In the battery voltage drop monitoring unit 50 in FIG. 2, assuming that a predetermined threshold voltage Vth1, for example, a rated voltage of the battery power supply, is 3.0 volts in order to detect a battery voltage drop, Vth1 = 2.35 volts is set in advance. The battery voltage drop is detected when the voltage of the battery power supply falls below the threshold voltage vth1 at time t1, and the battery voltage drop is detected when the battery voltage drop is detected, for example, twice consecutively in a predetermined detection cycle. Is determined (determination is detected), and the battery voltage drop flag 40 is set.

  On the other hand, the reset voltage Vth2 at which the processor 24 of FIG. 2 stops operating is, for example, Vth2 = 2.0 volts. Therefore, the remaining operable time T is from the time when the battery voltage drop is detected at time t1 until the time t2 when the voltage of the battery power supply drops to the reset voltage Vth2 at which the operation of the processor 24 stops, which is the memory 34 in FIG. Is stored in advance as a value of the remaining operable time 42.

  For this reason, when a battery voltage drop is detected at time t1, the value T of the remaining operable time 44 stored in the memory 34 is set as an initial value in a counter on software realized by executing a program, for example. The remaining operable time that changes in real time can be acquired by subtracting the time unit in units of 1 hour, for example, 1 hour. Alternatively, the remaining operable time corresponding to the detection value of the battery voltage is held as the remaining operable time 42 in the memory 34 in a table format, and the remaining operable time is acquired from this table based on the detected voltage value at the appropriate time. May be.

  When the multifunction switch 20 detects a second or subsequent operation after the battery voltage drop determination is detected or a push operation such as a long press, the second battery exhaust warning can be output as a voice message.

  Referring to FIG. 2 again, the inspection processing unit 52 performs a predetermined internal inspection and outputs the inspection result from the notification unit 8 when detecting the operation of the multifunction switch 20 provided in the operation unit 30 in the normal monitoring state. Let As for the output of the inspection result, if there is no abnormality, an inspection result message including, for example, “normal” is output, and if a failure is detected, an inspection result message such as “pick failure” is output. The contents to be inspected in the inspection process include presence / absence of smoke detector 16 (sensor) failure, presence / absence of circuit failure, presence / absence of sensitivity abnormality, presence / absence of other failures, and the like. Here, the presence or absence of a battery voltage drop can also be included in the contents of the inspection.

  For example, for the detection of sensor failure, the inspection processing unit 52 reads the smoke detection signal output from the smoke detector 16 of the sensor unit 26 at a predetermined measurement time interval T2, for example, T12 = 1 second by A / D conversion, and stores the memory. 34, for example, every predetermined time interval T3 = 10 minutes, the average value of 10 minutes of detection data (stored data) held in the buffer area of the memory 34 is obtained, and this average value is When the output level is below a predetermined reference level (referred to as the zero point level), it is determined that the smoke detector 16 has failed. When the multi-function switch 20 is operated, an inspection result message such as “pick failure” is output from the speaker 44. Output.

  The reason why the 10-minute average value of the smoke concentration detection signal falls below the zero point level in this way may be that a failure such as disconnection of the light receiving element provided in the smoke detector 16 or stop of the light receiving amplifier has occurred. Is expensive. Even when a temperature detection element such as a thermistor is provided in the sensor unit 16, a sensor failure or failure can be detected in the same manner.

  When the multifunction switch 20 is operated while a failure (including a failure) is detected, a failure alarm stop process may be performed after performing a predetermined internal inspection and informing the result. In this way, for example, the failure alarm stop process is performed after rechecking the sensor failure or the like, so that the user can be more clearly aware of the failure state. If the failure state has been resolved at this time, for example, a message such as “The failure has been resolved” may be output, and the processing may proceed to failure alarm stop processing.

  FIG. 5 is a flow chart illustrating the processing operation in the residential alarm 10 of FIG. 2, and distinguishes between battery warnings by the first operation of the multifunction switch 20 after the battery voltage drop determination detection and the second and subsequent operations. The processing embodiment is taken as an example.

  In FIG. 5, when the power supply by the battery power source 38 of the mortgage alarm device 10 is started, initialization and self-diagnosis are executed in step S1, and if there is no abnormality, the process proceeds to step S2 to determine the presence or absence of fire detection, If fire detection is discriminated, the process proceeds to step S3, and a fire alarm is output by a voice message from the speaker 44 and an alarm display by turning on the LED 22.

  Subsequently, in step S4, it is determined whether or not the multifunction switch 20 is operated. When the switch operation is determined, the alarm sound from the speaker 44 is stopped in step S6, and the alarm display by turning on the LED 22 is turned off. Stop the alarm. That is, at this time, the multi-function switch 20 functions as an alarm stop switch. In the alarm stop process, the LED 22 may be turned off after a predetermined time has elapsed.

  If the switch operation is not determined in step S4, the presence or absence of the fire recovery is monitored in step S5. When the smoke detection signal from the smoke detector 16 is lowered and the fire condition is resolved, the fire recovery is determined. In step S6, the fire alarm is stopped as described above.

  Subsequently, in step S7, it is determined whether or not the battery voltage drop determination is detected. If the battery voltage drop determination is detected, the process proceeds to step S8, where the battery voltage drop flag 40 in the memory 34 is set, and at the same time, the periodic ring timer. Then, the process proceeds to step S9, where, for example, “battery is out of battery” is output three times as a battery exhaustion alarm, and at the same time, the LED 22 blinks in synchronization with the alarm sound.

  Subsequently, in step S10, it is determined whether or not the multifunction switch 20 is operated. If it is determined that there is an operation, the process proceeds to step S11, and it is determined whether or not the battery voltage drop flag 40 is set. If it is determined that the battery voltage drop flag 40 is set, the process proceeds to step S12, and it is determined whether or not the operation is the second or later operation. If the first operation is determined, the process proceeds to step S13. Please contact your dealer. ”Is output.

  If it is determined in step S12 that the operation has been performed for the second time or later, the process proceeds to step S14. As a second battery exhaustion alarm, for example, “Please contact your dealer. Output.

  On the other hand, if the operation of the multi-function switch 20 is not determined in step S10, the process proceeds to step S15, where it is determined whether it is a periodic ringing timing by the periodic ringing (alarm) timer started in step S8, and the periodic ringing timing is determined. At that time, the process proceeds to step S16, and for example, an alarm sound “battery exhausted” is output three times as an alarm for every hour, for example.

  In step S10, the switch operation of the multi-function switch 20 is determined and the process proceeds to step S11. However, when the reset of the battery voltage drop flag 40 is determined in step S11, it is regarded as the operation of the inspection switch because it is in the normal state. Proceeding to S17, inspections such as the presence / absence of failure of the smoke detector 16, the presence / absence of a circuit failure, the presence / absence of sensitivity abnormality, and the presence / absence of other failures are performed, and the inspection result is output at step S18.

  FIG. 6 is a flowchart illustrating the processing operation in the residential alarm 10 of FIG. 2, and an embodiment of the residential alarm processing for distinguishing the battery exhaustion alarm by the normal operation and the push operation of the multifunction switch after the battery voltage drop determination is detected. For example.

  6, steps S21 to S31 are the same as steps S1 to S11 in FIG. 5, steps S35 to S38 are the same as steps S15 to S18 in FIG. 5, and steps S32 to S34 are the same as those in the present embodiment. This is a battery low warning process.

  In step S30 of FIG. 6, it is determined whether or not the multifunction switch 20 is operated. If it is determined that there is an operation, the process proceeds to step S31, and it is determined whether or not the battery voltage drop flag 40 is set. When it is determined that the battery voltage drop flag 40 has been set, the process proceeds to step S32, where it is determined whether or not a push operation such as a long press such as 2 to 3 seconds is performed. When a normal operation is determined, the process proceeds to step S33. For example, “Please contact the store” is output.

  If it is determined in step S32 that the push-down operation has been performed, the process proceeds to step S34, and for example, “beep battery is out of service. Please contact your dealer. The remaining operable time is about XX hours” is output.

  In this embodiment, there is an advantage that the remaining operable time can be known at any time by pressing the multifunction switch 20 in the state where the battery voltage drop is detected.

  In a state where the long press operation can be accepted, the LED 22 can be blinked for a longer time period than other blinking operation states so that the user can recognize that the long press operation can be accepted.

  In addition, although said embodiment took the example of the residence alarm device which detects and alarms a fire, it is the same also about the alarm system which has arrange | positioned the gas leak alarm device, CO alarm device, and various security alarm devices. Applicable to.

  In the above embodiment, the voltage of the battery power source is compared with the threshold voltage every predetermined time to detect a battery voltage drop. However, the test current corresponding to the operating current at the time of an abnormality alarm to the battery power source every predetermined time. It is also possible to provide a battery test circuit for testing by connecting a dummy resistor that conducts current, and to detect a battery voltage drop by comparing the battery voltage during the test with a threshold voltage. Thus, it is possible to accurately detect whether or not the home alarm is at a battery voltage capable of alarm operation, and to accurately determine the remaining operable time until the operation of the processor stops. In this case, when the battery voltage drop is detected, the operation of the battery test circuit is stopped to suppress the battery voltage drop.

  In addition, the attached information and detailed information included in the second battery low alarm are not limited to the remaining operable time, but can be other information, or the other information can be added to the first battery low alarm. . Here, it is not prevented that there are a plurality of attached information and detailed information. In short, the contents of the first battery warning and the second battery warning need not be the same.

  Further, both the first battery exhaustion alarm and the second battery exhaustion alarm are not limited to voice message output, and may be identified by various output means such as a buzzer sound and display, or a combination thereof.

  Further, the content of the battery low alarm at the time of detecting the battery voltage drop may be the same as or different from the content of the first battery low alarm when the multi-function switch 20 is operated with the battery voltage low flag set. It may be content.

  In the above-described embodiment, the battery exhaustion alarm has been described as an example, but similar alarm processing can be performed for other urgent alarms. That is, the present invention can also be applied to output of inspection results.

  In addition, the above embodiment is an example of a stand-alone type that is installed and used by a resident alarm alone, but includes a wireless communication unit, and transmits and receives event signals to and from other resident alarms. It can also be applied to a wireless interlocking house warning device that performs interlocking alarms.

  Further, the operation means shown as the multi-function switch 20 in the above embodiment does not necessarily need to be a switch, and any operation means such as instructing alarm history output by external communication using a remote control device or the like. Means and methods may be applied, and the “operation unit” in the scope of the utility model registration claim includes these other means and methods.

  In addition, the flowcharts in the above-described embodiments have described a schematic example of processing, and the order of processing is not limited to this. Further, it is possible to provide a delay time between each process or between processes, insert another determination, or the like.

  In addition, depending on the standard of the alarm device, the display by the LED of the above embodiment may not be recognized as “alarm”, but in the present invention, the alarm display is performed regardless of whether it is included in the “alarm” in the standard. It is described as a display accompanying an alarm or simply as a display. Any display means may be used as long as the object of the present invention can be achieved.
