Bosch D273THS Four-Wire Smoke Detector with a 135F Heat Sensor, Sounder


  • Also known as: DS-D273THS, BOS-D273THS

    • The Bosch D273THS 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 D273THS signals an alarm condition. After the alarm condition clears, interrupt power at the control panel to reset the detector.

    The D273THS is equipped with a 135F (57C) heat sensor and a sounder.    		Features:
    • Fourwire smoke detector with a 135F (57C) heat sensor and a sounder
