摘要
The electronically controlled fire detection system is designed to operate various warning elements and or protection devices by relays controlled by variable resistance surveillance detection. The system has a first transistor whose base and emitter are connected to the terminals of the detector circuits and which control the conductivity of a second transistor. The second transistor controls the supply of one or several relays controlling the warning and or protection elements. A third transistor controls the supply of a supplementary relay designed to control a fault signalling element when a fault occurs in the circuit of the detectors.
