Discovery Photoelectric Smoke Sensor: VF5601-0M SLC Devices USCG Type Approved 161.002/A53/0 Standard Features - Compatible with Elite and Elite RS-M control panels - 5 operating modes - Drift compensation - Two status LEDs - Address is set by X-Pert card and is stored in base - User memory - Alarm flag for fast alarm reporting - Conventional false safe mode - Polarity insensitive The VF5601-0M Discovery Photoelectric detector uses the same outer case as the ionization smoke detector and is distinguished by the indicator LEDs which will flash when the detector is in standby state and steady red in alarm. The housing is white polycarbonate and will not fade. Terminals are nickel plated stainless steel. Bases and cards are not included with detectors, please order separately. Top View - Photoelectric Smoke Detector Within the case is a printed circuit board which, on one side, has the light-proof chamber with integral gauze surrounding the optical measuring system and, on the other, the signal processing and communications electronics. An infrared light emitting diode is arranged at an obtuse angle to the photodiode. The photo-diode has an integral daylight-blocking filter. The IR LED emits a burst of light every second. In clear air the photodiode receives no light directly from the IR LED, because of the angular arrangement and the chamber Baffles. When smoke enters the chamber it scatters light 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 to provide an analog value for transmission when the detector is interrogated. 30 Second Alarm Delay Photoelectric Detector Operating Modes Fireboy-Xintex, Inc.
