Asenware AW-BK901-70 70 Meter Range Conventional Reflective Beam Detector

AW-BK901-70 is a reflective beam-type smoke detector with transmitter and receiver integrated into a single housing; it detects the presence of smoke by measuring the attenuation of the light beam reflected from a reflector mounted on the opposite surface. It connects to conventional fire detection panels, operates at 20-28 V DC with a standby current of 18 mA. The range is adjustable in three steps: 8-20, 40 and 70 meters; this variant is positioned in openings up to 70 meters, and sensitivity is selectable in three steps within the range of 2.6-4.8 dB. This operating principle within the EN 54-12 scope is suitable for scanning reservoir, atrium and sports hall volumes at heights unreachable by point detectors through a single line. During installation, the transmitter housing and reflector must be firmly fixed to vibration-free surfaces in direct line of sight; you may inquire with us prior to ordering whether the reflector set is included with the device or procured separately.
