Bosch D273THE Four-Wire Smoke Detector with a 135F Heat Sensor, EOL Relay


  • Also known as: DS-D273THE, BOS-D273THE

  • The Bosch D273THE 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 D273THE signals an alarm condition. After the alarm condition clears, interrupt power at the control panel to reset the detector.

    The D273THE is equipped with a 135F (57C) heat sensor and an EOL relay.

    These detector models measure light within a chamber using an infrared (IR) LED light source and a silicon photodiode. The chamber is covered with a fine screen to deter insects, reduce dust accumulation, and prevent nuisance alarms. Smoke particles reflect light onto the photodiode during a fire. When photodiode measurements exceed the alarm threshold, the detector triggers an alarm. After the alarm condition has been resolved, power must be cut at the control panel in order to reset the detector.
