In such a wireless interlocking warning system, when a fire is detected by a certain Smoke detector, the interlocking source Smoke detector that detects the fire, for example, sends a voice message saying "Woo Woo Fire! On the other hand, the interlocking Smoke Detector outputs a voice message saying "Woo, another fire alarm has been activated. Please check." In addition, the operation indicator light of the interlocking source Smoke detector is lit, the operation indicator light of the interlocking destination Smoke detector is blinking, and it is possible to distinguish between the interlocking source and the interlocking destination from the display of the operation indicator light. ..

In addition, the fire alarm can be stopped by operating the test switch of the fire alarm while the fire alarm is being output. At this time, the alarm stop interlocking signal is transmitted to the other fire alarm and the fire alarm is stopped in conjunction with it. To.

In addition, if the fire alarm outputs a fire alarm due to a factor other than the fire, the fire may be restored during the fire alarm. In this case as well, the fire alarm is stopped and another fire alarm is fired. A recovery interlocking signal is sent and the fire alarm is interlocked and stopped.

Furthermore, when the Smoke Detector detects a failure such as a dead battery, a communication test error, or a device failure, it outputs a battery dead alarm, a communication test error alarm, and a device failure alarm, and also outputs a failure interlocking signal corresponding to each. Is sent to other resident police to output a failure alarm.

The alarm function of such a housing alarm is to output a fire alarm, an alarm stop, a fire recovery, a failure alarm of a dead battery and a device failure in the same way even for a stand-alone fire alarm that does not have an interlocking function. I have to.
