Control Device Properties

Scene Set Plate is a push button device.

Sensor Head is a passive infrared (PIR) device that detects movement within a defined area – 9m x 7m 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.

The Scene Set Plate and PIR Sensor Head both operate at Protected Extra Low Voltage (PELV) – nominally 12V.

Operation

Luminaires are all turned on at a particular light level by pushing one of the buttons marked 1-4 on the Scene Set Plate. By default these are factory set at 100%, 75%, 50%, 25% but each can be reprogrammed at any time to any desired value.

Regardless of the scene selected, the PIR will monitor the area for occupancy. Once the area is vacated and the PIR Sensor Head has completed its time-out sequence the luminaires will automatically switch off.

Alternatively, pushing the master button at the top right hand corner of the Scene Set Plate will turn all luminaires off.

All luminaires 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 Scene Set Plate – 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 the Y connector into the Control Pack.
  7. Plug one end of the Switch Drop Lead into the Y connector.
  8. Plug one end of the Switch Drop Lead into the Scene Set Plate.
  9. Plug one end of the Sensor Lead into the Y Connector.
  10. Plug one end of the Sensor Lead into the PIR Sensor Head.
  11. Plug the luminaires into any outlet on the Distribution Box.

Tips and Tricks

Do not set target light level for FHN400 as incorporating daylight linking or daylight dependency with scene set/recall applications is not advisable.

The PIR Sensor Head’s default 20 minute time period can be changed to 2, 4, 10 or 40 minutes if required. One of our Setup Remote Controls (FRC/SET) will be needed for this task.

Although the flex7 Scene Set Plate looks like a switch, it uses similar software to our PIR Sensor Heads. As such, the Switch Drop Lead must be plugged into the sensor port at the Control Pack
