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.

Switch operates at Protected Extra Low Voltage (PELV) – nominally 5V.

Operation

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

Installation

  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 Switch – it mounts onto a standard 25mm deep single box with 60.3mm centres.
  4. Plug the Control Pack into any outlet on the Distribution Box.
  5. Plug one end of the Switch Drop Lead into the Control Pack.
  6. Plug one end of the Switch Drop Lead into the Switch.
  7. Plug the luminaires into any outlet on the Distribution Box.

Tips and Tricks

When using the Switch a ‘pulse’ should be ≤1 second.

Holding the Switch in one position > 1 second will have no effect in this particular scenario – if the lights are on they’ll remain on and vice versa.

Because flex7 controls operate at Protected Extra Low Voltage, compliance with IET Wiring Regulation (BS 7671:2018+A2:2022) 522.6.204 is met in most cases without the need for earthed mechanical protection covering/enclosing the Switch Drop Lead or the addition of RCD protection of the particular circuit at the distribution board.

Installers must ensure compliance with BS 7671 in every instance.
