Optical Smoke Detector Dealers in Meerut (1 products available)

We have come up with highly effective Optical Smoke Detectors. This Optical Smoke Detector uses the same outer case as the ionization smoke detector and is distinguished by the indicator LED which is clear in standby and red in alarm. Within the case is a printed circuit board which has the light proof labyrinth chamber with integral gauze surrounding the optical measuring system as well as the address capture, signal processing and communications electronics. Our Optical Smoke Detectors are offered in the brand name of Context Plus XP95 optical detector. Functioning An infrared light emitting diode within its collimator is arranged at an obtuse angle to the photo-diode. The photo-diode has an integral daylight-blocking filter. The IR LED emits a burst of collimated light every second. In clear air the photo-diode receives no light directly from the IR LED because of the angular arrangement and the dual mask. When smoke enters the chamber it scatters photons from the emitter IR LED onto the photo-diode in an amount related to the smoke characteristics and density. The photo-diode signal is processed by the optical ASIC and passed to the A/D converter on the communications ASIC ready for transmission when the device is interrogated. Download
