Then, the electric lock 7 is unlocked by the control signal.

  In addition, when the response button 22a is operated for a long time (for example, for 3 seconds) while the alarm sound and the alarm message are sounded from the speaker 12, the operation input receiving unit 19 performs an operation input for stopping the alarm sound. The operation signal for stopping the alarm sound is output to the base unit control unit 10. The master control unit 10 that has received the alarm stop operation signal stops the alarm sound and alarm message from the speaker 12 and the display of the fire alarm message by the display device. Further, the base control unit 10 generates a locking instruction command for instructing the electric lock control device 8 to lock the electric lock 7 and outputs the lock instruction command to the second wired communication unit 24. The second wired communication unit 24 transmits a locking instruction signal including a locking instruction command output from the parent device control unit 10 via a signal line.

  When the locking instruction signal transmitted from the second wired communication unit 24 of the base unit 1 is received by the wired communication unit 81 of the electric lock control device 8, the control unit 80 of the electric lock control device 8 outputs the locking instruction signal. In accordance with the included lock instruction command, a control signal for locking the electric lock 7 is transmitted from the control signal transmitter 82 via the control line Lc. Then, the electric lock 7 is locked by the control signal.

  As described above, according to the present embodiment, when a fire is detected by the fire detector 4, the electric lock 7 installed on the entrance door D of the dwelling unit H is automatically unlocked, so no operation by the resident is necessary. Thus, there is an advantage that usability and safety are improved. As shown in FIG. 13, an alarm message “It is a fire” and an alarm sound “Pipo, Pipo” and a voice message for notifying that the electric lock 7 of the entrance door D is unlocked (for example, “ The main unit control unit 10 may be caused to alternately ring from the speaker 12 ”. If it does in this way, it can alert | report that the electric lock 7 was unlocked automatically and can evacuate a resident smoothly.

  Here, in the base unit control unit 10 of the base unit 1, as described above, when the first wired communication unit 23 receives the fire detection signal, the first operation mode that outputs the unlock instruction command, When the first wired communication unit 23 receives the fire detection signal, it operates alternatively according to any one of the second operation modes in which the unlock instruction command is not output and is received by the operation input receiving unit 19. One of the first and second operation modes is alternatively selected according to the operation input. Furthermore, base unit control unit 10 stores in memory unit 20 which of the first operation mode and the second operation mode is selected, and the operation mode stored in storage unit 20 is the first operation mode. When the mode is the mode, the light emitting diode of the display unit 21 is turned on. When the operation mode stored in the storage unit 20 is the second operation mode, the light emitting diode of the display unit 21 is turned off to Is displayed on the display unit 21. Therefore, one of the first operation mode in which the electric lock 7 is automatically unlocked when a fire occurs and the second operation mode in which the electric lock 7 is not automatically unlocked when a fire occurs. In addition, it is possible to check on the display unit 21 which operation mode is being operated.
