視電流を低く押えるようにした、電圧の変動する電源を
備えた受信機に接続１．て使用する定電圧火災感知器。When the fire detection section (including its amplification circuit) is under constant load, a constant current circuit can be connected in series with the fire detection section between a pair of power supply lines. By connecting a constant voltage circuit in parallel with the fire detection section and connecting a constant current circuit in series with the reference voltage element in the constant voltage circuit between a pair of power supply lines, the monitoring current of the fire detector can be lowered. Connect to a receiver equipped with a variable voltage power supply that is designed to hold down 1. Constant voltage fire detector used in
