The PIR (passive infra-red) detector senses movement of warm bodies against a cooler background. The detection pattern is broadly rectangular at 7.4m x 5.6m when fixed at a ceiling height of 2.5m (longest length of detection aligning with the spring clips). For further details see occupancy detection pattern.
3 types of Sensor Heads are available:
Occupancy Sensor Head
Occupancy Sensor Head with Light Level Sensing
Slave Occupancy Sensor Head

Note: A Sensor Link Lead will be required to connect your Sensor Head
