Title: Interruption monitoring device for fire alarm equipment
Inventor: TAKAHASHI KAORU
IPC: G08B29/06
Filed: 1989-06-29
Abstract: PURPOSE:To monitor interruption without fail by discriminating the presence and absence of the interruption in a power supply and signal line corresponding to difference between voltages before and after the interruption. CONSTITUTION:When the time of calling from a receiver RE to a repeater T1 reaches the time set in advance, a microcomputer MPU reads the voltage of an A/D converter 10 just before the interruption. Afterwards, by setting an OUT 1 to H, transistors Tr1 and 2 are turned-OFF and a constant current circuit CC1 for charge is turned-OFF. Then, power supply to a power supply and signal line L is interrupted. After the lapse of prescribed time, the voltage of the converter 10 just after the interruption is read and an OUT2 is set to H. Then, a constant current circuit CC2 for discharge is turned-OFF and the OUT1 is set to L. Afterwards, the circuit CC1 is activated. The differential voltage, for which the voltage after the interruption is subtracted from the voltage before the interruption, is calculated. When the differential voltage is less than a reference for the discrimination of the interruption, it is judged that the interruption is not generated. When the differential voltage is more than the reference, it is judged that the interruption is generated.
