The ANWETECH AT-B01 Linear Beam Smoke Detector is a reflective beam-type smoke detector designed for large open spaces where point smoke detectors may be difficult to install or maintain.
The detector transmits an infrared beam to the reflector and monitors the reflected signal. When smoke enters the beam path, the light intensity is reduced. The detector analyzes the attenuation and provides fire alarm or fault signals through LED indication, buzzer, relay outputs and RS485 communication.
AT-B01 is suitable for warehouses, shopping malls, museums, archives, large workshops, aircraft hangars, power plants, halls, historical buildings and other high-ceiling or wide-area applications.
Built-in laser module for fast aiming and commissioning.
5m to 100m detection distance for large open spaces.
Reflective beam design with detector and reflector.
8 built-in sensitivity levels for different site environments.
Automatic light compensation for environmental changes.
Fire alarm relay output and fault relay output.
RS485 communication interface.
Red, yellow and green LED status indication.
Buzzer indication for commissioning and alarm status.
Suitable for warehouses, halls, malls, hangars and large buildings.
