This auction is for one BOSCH D282A Photoelectric Smoke Detector Head RADIONICS Fire Alarm
D282A/D283A Photoelectric Smoke Detector Heads ? 24 VDC input ? Mounts on low-profile base ? Easy head removal for cleaning and servicing ? Two-wire and four-wire base options ? Flashing Power-On LED ? Steady-On Alarm LED ? Remote annunciation ? Tamper-resistant locking base www.boschsecurity.com The D282A and D283A detectors detect the large smoke particles which typically result from wood, paper, and fabric combustion. The D283A is a smoke detector that also has a +135?F (+57?C) fixed temperature heat sensor. Use in areas where the ambient temperature does not exceed +100?F (+38?C). These detectors are compatible with 24 VDC circuits. These detectors have two components: the detector base and the detector head. The base is permanently attached and wired to a back box. The interchangeable heads quickly detach for replacement and cleaning without affecting circuit wiring. Functions Detection chamber operation The D282A and D283A Smoke Detectors use an infrared (IR) LED light source and a silicon photodiode to measure light in a chamber. In normal conditions the light is absorbed in the chamber. The presence of a significant number of particulates reflects the light to the photodiode. After two consecutive measurements exceeding the basic level, the unit signals an alarm condition. The detector can be reset from the control panel, after an alarm condition clears, by interrupting power. The detection chamber, designed for reliable smoke entry characteristics, is protected by a micro-fine insect screen to reduce dust accumulation and insect penetration and minimize nuisance alarms. Internal diagnostic test These heads have moisture-proof reed switches that react to an external magnet for testing. The magnet test simulates a 4% to 6% smoke obscuration that places the detector in an alarm condition. This test results in specific LED and alarm circuit responses indicating the: ? detector is within calibration standards ? detector settings are outside sensitivity standards ? detector is not operational This test is especially useful in environmentally unstable or unclean areas. LEDs The D282A and D283A have two built-in bicolor LEDs that flash once every 3 sec: ? Green indicates the device is within calibration standards ? Red indicates the detector is outside its sensitivity limits Technical Specifications Environmental Considerations Relative Humidity: Up to 93%, non-condensing Temperature (operating): +32?F to +100?F (0?C to +38?C) Mechanical Properties Color: Bone white Material: PC/ABS blend (polycarbonate/polyacrylonitrile butadiene styrene) Good Condition, It may work with other Models  Check out my other items!
