Control of the luminaires is from 2 locations via flex7 plug-in switches operating at PELV. The luminaires are manually switched on or off with a short pulse of either of the switches.

The use of flex7 control modules negates the need for RCD and/or earthed mechanical protection of the switch drop. The installation of strappers, usually required for 2-way / intermediate switching, is not necessary. Both switches simply plug into the control module.

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.
