The ADDRESSABLE MULTISENSORY DETECTOR is an attractively - styled, low profile combined photoelectric smoke and heat detector for use with the fire alarm control panel of NFU - 7000 series. This detector is an analog detector that has enabled each detector address to provide exact detector locations. The smoke sensitivity of this detector can be programmed using the control panel software to suit the environment. The detector sensitivity is continuing ally monitored and reported to the panel. The ADDRESSABLE MULTISENSORY DETECTOR has a new sophisticated smoke chamber design and an orange sensor LED which can provide the same sensitive detection regardless of the type of smoke. This detector has a chemically etched, stainless steel insect screen therefore reducing the ingress of insects and airborne contaminants. The ADDRESSABLE MULTISENSORY DETECTOR initiates an alarm in response to both rapid rate - of - rise conditions and fixed heat (57 ° C). Heat portion incorporates a highly linear thermistor circuit, with the thermistor mounted externally. The specially designed cover protects the thermistor while allowing maximum air flow.
