FIRE MONITORING SYSTEM OF SELECTING EARLY FIRE ALARM MODE FOR CONNECTING SERIALLY HEAT SENSOR TO SMOKE SENSOR

摘要

Purpose: a fire monitoring system enhances the alarm function and a fault alarm prophylactic function of an early stage by being selectively arranged to using the alarm mode of an early stage and a fault alarm control models. Construction: a fixed plate (10) is fixed on a piece of ceiling and the connecting terminal including being connected to a power supply. One controller (20) includes a control flow (21), it is used to control a heat-sensitive sensor (51) and a cigarette sense (31), one fault alarm control models, it is used to be continuously connected heat-sensitive sensor to cigarette sense, the alarm mode of one early stage, its be used for connect is parallel to mutual heat-sensitive sensor and cigarette sense and a mode selection switch (24), be used for disconnect or connecting fault alarm control models from or to early stage alarm mode. One mist detecting device (30) includes cigarette sense for feeling cigarette. One cover board (40) is coupled to fixed plate, and mist detecting device is escaped in order to prevent. One heat detection unit (50) includes the heat-sensitive sensor for sensing heat.
