Sensor Head is a passive infrared (PIR) device that detects movement within a defined area – 9m x 7m each when mounted at a height of 2.5m.

PIR Sensor Head also includes an integral light sensor that can measure variations in the available ambient light.

PIR Sensor Head operates at Protected Extra Low Voltage (PELV) – nominally 12V.

Luminaires are all automatically turned on when movement is detected by the PIR Sensor Head.

The integral light sensor measures the available ambient light and maintains the area’s set target level by decreasing or increasing the light output of the luminaires adjacent to the window.

Non-dimming luminaires will be unaffected by the light cell’s operation and remain on.

Once the area is vacated and the PIR Sensor Head has completed its timeout sequence the luminaires will automatically switch off.

Luminaires adjacent to the window must have DALI drivers/control gear.

1. Install the Distribution Box using the fixing kit provided.
2. Terminate the fixed wiring into the Distribution Box terminals – see adjacent schematic.
3. Fit the PIR Sensor Heads – each requires a 32mm hole.
4. Plug the Control Pack into any outlet on the Distribution Box.
5. Plug one end of the Sensor Lead into the Control Pack.
6. Plug one end of the Sensor Lead into the PIR Sensor Head.
7. Plug the luminaires into any outlet on the Distribution Box.
8. Using a Setup Remote Control (FRC/SET) enable presence.
9. Using a Setup Remote Control (FRC/SET) set the desired target light level.

Luminaires will always turn on at full output before daylight linking commences.

One of our Setup Remote Controls (FRC/SET) is required to set the desired target light level – instructions are provided.
