The C-Bus® Outdoor PIR Occupancy Sensor is a C-Bus input unit 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.

The sensor is suitable for controlling lighting in homes, apartments, offices, corridors, conference rooms, etc. The sensor incorporates the C-Bus ‘Learn Mode’ feature. Learn mode allows the units to be programmed without the need for a PC connected to the system. Alternatively, the units can be programmed via a PC using the installation software.

The sensor has a detection field that covers an area up to 18 metres from the unit, with a field of view of 110 degrees. Advanced microprocessor circuit technology and a flat multi-segmented lens drives the field of view into 48 zones located at four different levels. This ensures immediate reaction to body movement and reduces the number of ‘dead zones’ that can be penetrated.

The sensor is capable of controlling up to four C-Bus ‘Group Addresses’, with each being controlled for a different period if required.

An added feature is that each sensor includes an ambient light level sensor (Sunset Switch) feature, which automatically turns lights on when the ambient light level falls below the threshold level (at sunset), and then turning the lights off again at sunrise. Alternatively, the lights can be programmed to automatically turn off at a set time after sunset.A light emitting diode (LED) on the sensor head can be programmed to turn on when movement is detected. This enables easy positioning and commissioning of the sensor.

The outdoor models rugged construction ensures that it meets an IP66 rating, enabling it to be used in severe weather conditions
