Abstract

PROBLEM TO BE SOLVED: To ensure periodic replacements of a sensor by adding a reporting function of replacement time period of the sensor inside each house and a management room master unit to a house information panel. SOLUTION: Upon detecting an abnormality at the time of monitoring by a sensor 2, the sensor outputs a state signal f1 composed of a sensing signal f11 of an output voltage different from that at the time of monitoring to a reception circuit 11, while the reception circuit which receives and detects the state signal (sensing signals) outputs a security signal f2 to a control circuit CPU 1. The control circuit which receives and detects the security signal allows an alarm sound to be emitted from a speaker SP1 of an alarm sound emission part 12 and allows an alarm display lamp LED(light emitting diode) 1 to be lighted. Also, when a timer circuit 15 detects the lapse of a prescribed time which is the replacement time period of the sensor, the control circuit sends out timing end signals f20 through a transfer circuit 17 to the management room master unit 20, allows a timing end notifying sound to be emitted from the speaker of the alarm sound emission part and allows a timing end display lamp LED2 to be lighted.

It can be confirmed that the sensor 2 is in an emergency where a gas leak and / or carbon monoxide has been detected. Further, when the timer circuit 15 measures a predetermined time (five years), which is the time to replace the sensor 2, and outputs a data signal f7 indicating that the time measurement has ended to the control circuit CPU1, the control circuit which has detected the input of the data signal f7 The CPU 1 outputs a (high-level) transfer signal f19 from the transfer output terminal T12.

It is possible to reliably determine that it is time to replace each sensor 2. At this time, the user of the house information panel 1 occupying the dwelling unit, the manager using the management room base unit 20, or the like issues the time-out end notification sound in the house information panel 1 and the time-out end indicator light LED2. When the stop switch SW2 of the switch unit 13 is depressed by confirming the lighting and the input of the clock end signal f20 in the control room base unit 20, the control circuit CPU1 notifies the H level output from the notification sound output terminal T6. The output of the signal f4 is stopped to stop the timing end notification sound. When the reception switch SW1 is opened and the sensor 2 is replaced, and the reception switch SW1 is closed again and the light-off switch SW3 is pressed, the control circuit CP
U1 stops outputting the H-level notification signal f6 output from the second display terminal T11, turns off the timer end indicator LED2, sends out the timer reset signal f8 via the reset circuit 16, and turns the timer circuit 15 on. Since the reset is performed, the timer circuit 15 starts measuring the predetermined time (five years) again.
