FIG. 5: is a flowchart which shows an example of the interlocking alarm process of the fire alarm for wireless houses (200-227).
In this system, when the fire alarm 1 for the wireless home that is the source of the fire generates an alarm output, a wireless signal including a fire signal is transmitted to the nearby fire alarm 1 for the wireless home, and then it is used as a relay point. The other wireless house fire alarm 1 is subjected to a process of transmitting a radio signal including an interlock signal, and an alarm is output from the entire system.

  That is, when any of the wireless home fire alarms 1 detects a fire factor, the alarm device 1 sets a fire detection flag, outputs an alarm, and transmits a radio signal including a fire signal. In response to this, the neighboring fire alarm 1 for the wireless house outputs an alarm and transmits a radio signal including a fire interlocking signal when an alarm stop timer to be described later is not set. The other wireless residential fire alarm device 1 that has received a wireless signal including such a fire interlocking signal outputs an interlocking alarm when an alarm stop timer to be described later is not set.

  In addition, when the alarm stop button 13C is operated on the fire alarm 1 for the wireless home that is the source of the fire while the entire system is outputting an alarm, the alarm of the alarm 1 is stopped and other alarm devices A reset signal is transmitted to 1, and all alarms of the system are stopped for a predetermined time. On the other hand, when the alarm stop button 13C is operated on the fire alarm 1 for the wireless house other than the fire source, the alarm of the alarm 1 is stopped and a reset signal is transmitted to the other alarms 1. The source alarm device 1 ignores the reset signal and continues the alarm output, and the alarm device 1 other than the fire source receives the reset signal and stops the alarm output for a predetermined time.

  That is, when each of the fire alarms 1 for a wireless house receives a reset signal from any of the fire alarms 1 for a wireless house, if the fire detection flag is set, the alarm output is continued as it is. On the other hand, when the fire detection flag is not set, the alarm output is stopped for a predetermined time. As a result, the alarm output is not stopped only at the source of the fire, and the alarm output other than the source of the fire is stopped, so that it is easy to identify the fire source.

When the alarm stop button 13C is operated, if the fire detection flag is set, the alarm detection button 13C is reset to stop the alarm and transmit a radio signal including a reset signal.
On the other hand, if the fire detection flag is not set, the alarm is stopped for a predetermined time and a reset signal is transmitted.
Here, the alarm stop timer does not output an alarm even if it receives a fire signal or a fire-linked signal for a predetermined time after receiving the reset signal or after the alarm stop button 13C is operated. Until the timer is reset, even if the fire-source wireless residential fire alarm 1 outputs an alarm again, the alarm is not interlocked.
