1:The AW-BK901 reflective optical beam smoke detector incorporates a light transmitter and the detector on the

same unit. The light path is created by reflecting light emitted from the transmitter off a retro-reflector, meaning

it is reflects light back to its source with a minimum of scattering, which is placed opposite the detector.

2:In a fire, when smoke falls within the path of the beam detector, some of the light is absorbed or scattered

by the smoke particles. This creates a decrease in the received signal, leading to an increase in optical obscuration.

This unit decodes or analyzes received signals and compares to the pre-programmed algorithm stored on the processor.

3: Through this algorithm the detector will decide whether fire is defined or not and lead to enablement the

corresponding relays and LED indicators. The unit on the operating mode maintaining continually emitting light,

care should be taken that the activities in the space do not obstruct the beam or move the device to avoid false

operation of the detector.

ASENWARE was established in 2005. We have focused on the Fire Alarm and BMS

(Building Management System) over 11 years. Our headquarter is in London, UK.
We develop and manufacture addressable fire alarm system, conventional fire alarm system,

fire extinguisher, CCTV camera and DVR, and DDC for HVAC system.
