てなる火災感知器の状態区分回路。The output of the detection unit, which detects changes in the brightness of the space due to flickering of flames or changes in illuminance due to smoke, is guided through a correction circuit to two frequency detection circuits with different set values, respectively.
A that receives the output of the frequency detection circuit in a fire detector that calculates the output frequency and amplitude of the detection unit and the number of pulses within a certain period of time, and also detects fire from the duration of the signal.
In the ND circuit, a time comparator with a short duration (a set time comparator and a time comparator with a long duration set) are connected in parallel, and a b contact relay of the output circuit connected to the time comparator is interposed between the time comparator and the output circuit.
