70 Meter Conventional Reflective Beam Detector AW-BK901-70
AW-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 points to the exact location where to mount the mirror and with an additional digital guide, the 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, 40, 70 and 100 meters beside three adjustable sensitivity settings range from 2.6dB to 4.8dB to meet the specific environmental requirement. The AW-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. Secure and quick communication through the onboard processor enables the detector to make its own decision and drift compensation resulting in greater automation.
The AW-BK901 is ideal for use high ceiling and wide areas such as warehouses, large storages, shopping malls, leisure centers, exhibition halls, hotel lobbies, printing houses, garment factories, museums, and prisons, as well as places where slight smoke particles or corrosive gas exist.
