Control Device Properties

Switch is a 2-position retractive type ie. it can be pulsed up/down but when released always returns to the centre position.

Sensor Heads are passive infrared (PIR) devices that detect movement within a defined area – 9m x 7m each when mounted at a height of 2.5m.

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

Switch and PIR Sensor Head both operate at Protected Extra Low Voltage (PELV) – nominally 5V and 12V respectively.

Operation

Luminaires are all turned on manually using the flex7 Switch. Pulse in one direction to send an on signal.

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.

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

Alternatively, pulsing the switch to send an off signal will turn all the luminaires off before the timeout sequence has elapsed.

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

Installation

  1. Install the Distribution Box using the fixing kit provided.
  2. Terminate the fixed wiring into the Distribution Box terminals – see schematic above.
  3. Fit the Switch – it mounts onto a standard 25mm deep single box with 60.3mm centres.
  4. Fit the PIR Sensor Head – it requires a 32mm hole.
  5. Plug the Control Pack into any outlet on the Distribution Box.
  6. Plug both Y Connectors into the Control Pack.
  7. Plug one end each Switch Drop Lead into the Y Connector.
  8. Plug one end of the Switch Drop Lead into a Switch.
  9. Plug one end of the Sensor Lead into the Y Connector.
  10. Plug one end of each Sensor Lead into a PIR Sensor Head.
  11. Plug the luminaires into any outlet on the Distribution Box.
  12. Using a Setup Remote Control (FRC/SET) set the desired target light level.

Tips and Tricks

One of our Setup Remote Control (FRC/SET) can be used to disable the Absence function if desired. This will mean the luminaires turn on immediately the PIR Sensor Head detects movement – the Switch doesn’t need to be pulsed first.

The Switches can however still be used to temporarily override the PIR (either on/off) but when the timeout period elapses everything will return to normal operational state again
