Control of the luminaires is from 1 location via a flex7 plug-in switch operating at PELV. The luminaires are manually switched on or off with a short pulse of the switch.

The use of flex7 control modules negate the need for RCD and/or earthed mechanical protection of the switch drop.

Additionally, installation time is dramatically reduced as everything plugs-in, meaning only the 4 conductors at the Distribution Box require on-site termination.

Note: emergency luminaires are tested via a hard-wired 230V key switch, often located in close proximity to the distribution board.
