D263TH BOSCH 2-WIRE PHOTO/HEAT DETECTOR
D263TH Two+Wire Smoke/Heat Detector Two+wire photoelectric smoke detector with a 135°F (57°C) heat sensor.
These 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 to reduce dust accumulation and nuisance alarms.
D263TH 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.
Use a D132B Reversing Relay Module to activate the sounder (85 dB at 10 ft [3 m]). When using a D132B, the LED does not latch on alarm.
