D263TH BOSCH
D263TH 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.
- 12 V or 24 V input
- Designed for commercial or residential use
- Two-wire application
- Light-emitting diodes (LEDs) indicate the status of the chamber, power, and alarm
- Removable terminal block to simplify wiring connections
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.
D263TH Chamber Calibration
Tests Check the sensitivity and calibration of any of these detectors using a visual check, a magnet test, or a voltage measurement test. Visual check: When the detector’s calibration is within the factorylisted range, the red alarm LED flashes once every 3.5 sec. If the detector’s calibration is out of range for more than 24 h, the red alarm LED flashes once a second.
D263TH Magnet test:
Hold a magnet horizontally against the detector for about 10 sec and observe the LED.
- If the detector is within the factory-listed calibration range, it goes into alarm and the Alarm LED latches on.
- If the detector is too sensitive, the LED rapidly flashes six times (once every half second) and the detector signals an alarm.
- If the detector is not sensitive enough, the LED slowly flashes four times, once every 2 seconds, and the detector signals an alarm.
- If the detector does not operate, it does not signal an alarm.
