Introduction
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 *0, *0, *0 and **0 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.
