Lighting that sent the above detection signal
The turn-off determination circuit 5 determines that one heat sensor 1 has been heated and has operated, and operates the solenoid plunger 42 via the wireless device press circuit 6.

When the solenoid plunger 42 is operated, the talk button 32 of the transmitting radio 8 is pressed,
The transmission wireless device 8 enters a voice standby state. At this time, the sound generation circuit 7 having the sound generation board outputs, for example, the sound of the “warning area No. 1 alarm” including the number corresponding to the warning area, based on the operation signal from the lighting / light-off determining circuit 5. I do. The sound output from the sound generation circuit 7 is converted into a radio wave by the transmitting wireless device 8 and transmitted to the receiving wireless device 9 carried by the worker. The receiving radio 9 is the same as the transmitting radio 8.
It receives the transmitted radio wave and converts it into voice.

When the sound generation circuit 7 terminates the sound output of, for example, the "alarm zone No. 1 alarm" as described above, the sound generation circuit 7 outputs an end signal to the radio press circuit 6 to operate the solenoid plunger 42. Cancel. When the operation of the solenoid plunger 42 is released, the talk button 32 of the transmission radio 8 is released, and the transmission from the transmission radio 8 stops. When the worker working in the guard area confirms the sound of the “warning area No. 1 alarm” emitted from the receiving radio device 9, the one heat sensor 1
Is stopped and the cooling of the heat detector 1 is waited.

Then, when the one heat sensor 1 is cooled and the operation is stopped, the display lamp 12 which has been lit in the receiver 2 is turned off. The fact that the display lamp 12 has been turned off is determined by the light-on / light-off determination circuit 5 via the optical sensor 13 as being that the one heat sensor 1 has cooled down and has stopped operating. The on / off determination circuit 5 that has determined that the operation of the one heat sensor 1 has been stopped operates the solenoid plunger 42 via the wireless device press circuit 6 and causes the talk button 32 of the transmission wireless device 8 to operate. Is pressed to bring the transmission radio 8 into a standby state.

At this time, the sound generation circuit 7 outputs, for example, the sound of "restoration area No. 1 recovery" including the number corresponding to the warning area in response to the stop signal from the light-on / off judgment circuit 5. As described above, the sound output from the sound generation circuit 7 is converted into a radio wave by the transmitting wireless device 8 and transmitted to the receiving wireless device 9 carried by the worker. The receiving radio 9 is the same as the transmitting radio 8.
Receives radio waves transmitted from and converts them to voice. When the sound generation circuit 7 terminates the sound output of the “recovery area No. 1 recovery” as described above, the sound generation circuit 7 outputs an end signal to the radio press circuit 6 and the solenoid plunger 4
Release the operation of 2. By releasing the operation of the solenoid plunger 42, the talk button 32 is released, and the transmission from the transmission wireless device 8 stops. When the worker confirms the sound of the “recovery area No. 1 restoration”, the worker judges the inspection result and ends the inspection of the one heat sensor 1,
The inspection of other heat sensors is repeated in the same manner as described above.

The alarm unit 11 of the fire alarm inspection and notification device according to the present invention is, as shown in FIGS.
A radio insertion section 46 into which the transmission radio 8 is inserted in the vertical direction may be provided in the outer housing. In this case, the transmission radio device 8 is simply inserted into the radio device insertion portion 46, and the talk button 32 is pressed by the inner wall of the radio device insertion portion 46.
