PIR Sensor Heads
PIR Sensor Heads need to be used in conjunction with a Control Module. A Sensor Lead is needed to connect the Sensor Head to a Control Module. The PIR (Passive infrared) sensor detects moving bodies of hear that are different (warmer or cooler) to the background temperature. The detection pattern is broadly rectangular at 9m x 7m when fixes at a ceiling height of 2.5m (longest length of detection aligns with the spring fixing clips).
PIR Absence/Occupancy & Light Level Sensor Head (Primary)
- Use (in conjunction with appropriate Control Module) for occupancy or absence with daylight dependency/linking. Once a target light level has been set, the Sensor Head will monitor ambient light and turn on/off or dim/brighten luminaires as required.
- The integral infra-red receiver accepts commands from either the Setup or User Remote Control. An LED provides indication of operation.

PIR Auxiliary Sensor Head
- Use to increase the area of detection. Up to 5 Auxiliary Heads can be used in conjunction with 1 ‘Primary Head’, effectively increasing detection range by 6-fold. Ideal for use in corridors or large/irregular shaped rooms.
- Can be used with PIR or Microwave Sensors (excl. 230V version).
- Supplied with a ‘Y’ adaptor to allow plug-in connection of 2 Sensor Leads (in/out).
- Requires a ‘Primary’ Sensor Head, Control Module and Sensor Lead to operate.
