Bosch D273THCS Four-Wire Smoke Detector with a 135F Heat Sensor, Auxiliary Relay, Sounder 85 dB at 10 ft. Horn, Photoelectric


  • Also known as: DS-D273THCS, BOS-D273THCS

    • The Bosch D273THCS four-wire photoelectric smoke detector uses an infrared (IR) LED light source and a silicon photodiode to measure light in a chamber. A fine screen covers the chamber to deter insects and to reduce dust accumulation and nuisance alarms.

    During a fire, smoke particles reflect light onto the photodiode. When the photodiode measurements exceed the alarm threshold, the D273THCS signals an alarm condition. After the alarm condition clears, interrupt power at the control panel to reset the detector.

    The D273THCS is equipped with a 135F (57C) heat sensor, an auxiliary relay and a sounder.    		Features:
    • Fourwire smoke detector with a 135F (57C) heat sensor, an auxiliary relay, and a sounder
