Asenware AW-BK901-25 25 Meter Range Conventional Reflective Beam Detector

The AW-BK901-25 is a conventional beam-type smoke detector that continuously measures the infrared beam returning from the reflector mirror placed on the opposite surface to detect the presence of smoke. Since the transmitter and receiver are housed in a single unit, wiring is run to only one end; the reflector mirror supplied as a separate component is mounted on the opposite wall. This version is set for short spans in the 8-25 m range; other selectable stages of the same family with encoder cover the 8-100 m range in four steps. During commissioning, alignment is performed using the internal laser sight and digital alignment indicator; three-level sensitivity adjustment, automatic compensation against contamination and aging, self-diagnostic capability with fire and fault relay outputs are provided. The manufacturer declares that the device is manufactured to EN 54-12 compliance.
