Shop floor, 3000sqft sales area. Approx. 70-80 x 4 tube 14w T5 fittings.
Approx. 8-10 of these are integrated EM fittings.
All the fittings are plugged into 8 KLIK boxes, on 8 circuits, all run through 4 x 4 pole contactors - two for SL and two for L.
At the front door is a switch and a keyswitch.
The switch controls the normal on/off of the lights, controls 2 contactors.
The keyswitch controls the other 2 contactors, which isolate the ceiling lights conpletely, causing the EM lights to come on. These two contactors are normally permenantly engaged.
The regs require 3 hour test of the EM lights. How is this to be accomplished during normal trading hours? It cant be. How SHOULD the EM lights have been wired? On a seperate circuit? Were they being too clever with their wiring?
In the back areas of the store, every room has a EM switch, which knocks out the lights completely in that room and illuminates the EM. Even where the EM is seperate to the ceiling lights.
Again, 3hr test anyone?
