EST-BK901 Conventional Reflective Beam Detector has built in Laser beam pointing and Digital guide display for real user friendly alignment method. The Laser beam pointing accurately point the exact location where to mount mirror and with additional digital guide display allows to monitor and guide on the actual light intensity between the mirror and detector which cannot be seen by our naked eye making it more easy and convenient in alignment commissioning. The AW-BK901 has four adjustable operational ranges of between 8 to 20, 20 to 40, 40 to 70 and70to100meters beside with three adjustable sensitivity setting ranges from 2.6dB, 3.8dB and 5.8dBtomeetthespecific environmental requirement. The EST-BK901 works on the principle of reflective infrared beam obscuration. Used in conjunction with a reflector, it will notify the fire alarm panel when the infrared beam is obscured by smoke.
