ステムのアナログ中継器。 Power is supplied via the line from a monitoring means such as a receiver or trunk repeater, and the line voltage is lowered to a certain level and a transmission signal is sent in the set spacing band, and the address data of the received transmission signal is When the address matches the unique address set in advance, the analog data from the connected analog sensor is taken in based on the control data of the transmission signal, and the sensed data converted by the A/D converter is used as a return signal to send the transmission signal back. In an analog repeater of a self-fire alarm system that sends the signal back to the monitoring means during a waiting period, there is provided means for detecting the reception timing of a start pulse of a scan band transmission signal, and an A/D converter in synchronization with the detection signal of the means. 1. An analog repeater for a self-fire alarm system, comprising means for operating the A/D converter and latching the output data of the A/D converter.
