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 

with a reflectors, it will notify the fire alarm panel when the infrared beam is obscured by smoke. Secure and 

quick communication through the onboard processor enables the detector to make its own decision and drift 

compensation resulting in greater automation. 

The detector is ideal for use high ceiling and wide areas such as warehouses, large storages, shopping malls, 

leisure centres, exhibition halls, hotel lobbies, printing houses, garment factories, museums and prisons, as well 

as places where slight smoke particles or corrosive gas exist.
