Introduction
Overview
AW-BK901 Conventional Reflective Beam Detector has built-in laser beam pointer and digital guide display for real user-friendly alignment method. The Laser beam pointer accurately points 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 AW-BK901 has an ideal usage for 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.
Feature and Benefits
1. Manufacturing in compliance with EN54-12
2. Hassle free alignment, built with digital guide display and laser beam pointing
3. Employ single-ended design through reflective mirror.
4. Four ranges wide monitoring from 8-100 meters via encoder
5. Three users programming sensitivity adjustment
6. Built-in microprocessor
7. Self-diagnostic function to monitor internal faults
8. Automatic compensation for factors weakening received signals, such as dust intruder, positional movement and aging of the transmitter.
9. Fire and Fault interfacing relays
10. Attractive and pleasing appearance
11. Special user-friendly alignment method
