Tanda Conventional Reflective Optical Beam Smoke Detector – Relay Output for Large Spaces

The 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 beam detector has four adjustable operational range of between 8 to 20, 40, 70 and 100 meters beside
with three adjustable sensitivity setting ranges from 2.6dB to 4.8dB to meet the specific environmental
requirement. The detector works on the principle of reflective infrared beam obscuration. Used in conjunction
