FDO500 Low profile digital optical smoke detector. complete with self-learning circuit. EN54 part 7-17 certification N.1293-CPD-0340
Low profile photo-optical smoke detector, complete with self-learning circuit and short-circuit isolator. Smoke detectors work on the principle of light diffusion caused by smoke particles in the air. The detector has the function of automatic gain control; a microcontroller calculates the reading compensation to maintain constant sensitivity over time, correcting any increase in level caused by the deposit of dust inside the analysis chamber. Smoke detectors must be installed in places where there are no air currents that could divert the flow of particles produced by combustion and in places where normal activities do not produce fires of gaseous materials. Power supply voltage: 20Vcc (modulated voltage from -15% to + 10%) Average absorption at rest: 250 uA@20Vcc Absorption in alarm: 2mA@20Vcc Two-colour LED: red alarm - green normal operation Max relative humidity: 93% Operating temperature : 0 ÷ 50°C Weight: 70 g Dimensions: ø 90 x 31 (H) mm Certified EN 54 part 7 and 17 (1293-CPD-0138)
