Bosch D273 Fire & Intrusion Detector

Bosch D273 Fire & Intrusion Detector

The D273 Series Detector models use 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 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 detector signals an alarm condition. After the alarm condition clears, interrupt power at the control panel to reset the detector. When a D132B Reversing Relay Module is used, the LED does not latch on alarm.
