CATALOGUE NUMBER DESCRIPTION
5751LWE PIR indoor occupancy sensor-learn
5751LWE
The indoor occupancy sensors are surface mounted, input units used to detect movement by sensing natural
thermal radiation emitted from any moving body. When movement is detected, the unit issues commands over the
C-Bus network to control C-Bus output devices. In addition, the unit features a light level sensor to automatically switch
lighting on, under low light conditions.
The sensor has a detection eld that covers an area up to 8.5 metres from the unit, with a eld of view of 90 degrees.
The unit features a ‘lens less’ design with 12 overlapping zones forming a continuous detection eld, therefore resulting
in uniform sensitivity across the whole of the detection eld, with no dead zones. This features allows the sensor to be
ceiling or wall mounted.
The sensor features learn mode, which permits the unit to be programmed without the need for a PC connected to the system.
The sensor features an environmental rating of IP44 and is suitable for indoor applications. The sensor is designed for
surface mount applications, and located in the corner of the room where detection is required.
