Fire detector |
摘要 |
Fire detection apparatus includes a fire detector panel and an accumulation-type control panel in which the fire detection element is non-latching but the fire voltage detection circuit includes a fire indicator which is latched when a fire signal is detected for longer than a predetermined time. The circuit for latching is controlled by an accumulation circuit in the control panel that controls a relay closing that generates a fixed voltage suitable for the fire indicator.
