Mircom Photoelectric Smoke Detector The MIR-1400A ionization type smoke detector is specially designed to meet the stringent performance requirements of industrial and municipal fire detection/alarm systems. The design of the detector emphasizes ease of installation and field maintenance. All MIR-1400A ionization smoke detectors contain a unique dual source, dual unipolar chamber detection design which will sense the presence of smoke particles produced by fast combustion as well as slow smouldering fires. This chamber exhibits increased stability, significantly reduces nuisance alarms and provides better performance at higher air velocities. The MIR-1400A is designed to meet the performance criteria required by U.L.C. Additional key features include a blinking LED standby status indicator, an easily visible alarm indication and provision for convenient field test and metering. The MIR-1400A ionization detector is designed to be compatible with all Mircom Fire Alarm Control Panels. It is a low voltage detector and can be intermixed on the same detection circuits. It is recommended that no more than 30 detectors of any combination or type be used on any one (1) circuit. The detector is ULC listed and may be used where incipient products of combustion can be anticipated as a source, dependent on the particular environmental conditions. It is recommended that good engineering judgement is applied regarding location and spacing ** Please note that this product is a final sale and is not eligible for returns, refunds, or exchanges. ** Shop PureFilters PureFilters was founded with one mission - to improve the quality of indoor water and air by providing affordable filtration solutions that Canadians can trust.
