ABSTRACT:
In a fire detection system having at least one fire sensor, a receiver including a power source connected to the fire sensor for supplying a power source voltage to the fire sensor and a receiving relay for receiving a fire detection signal from the fire sensor, and at least one power/signal line for coupling the fire sensor to the receiver, the receiver comprises a timer for producing a clock signal over the time of day and command means for providing predetermined detection sensitivity change commands of the fire sensor which are programmed according to the time of day in response to the clock signal from the timer, and the fire sensor comprises sensitivity change control means for changing the detection sensitivity of the fire sensor in response to the detection sensitivity change command from the command means. The fire detection sensitivity of the fire sensor is varied in accordance with predictive fire damage conditions predetermined in view of the activities of people during the time of day. The system can realize an early discovery of fire to minimize the fire damage.
