Help with wiring keycard switch??!!

[rollonfriday]

Got to price job for local hotel to install key card switches in every room, but could do with some help in the best way to wire these (Which will allow me to price accordingly!)!

Currently there is 1 DB on each floor which serves all the rooms on that floor, the DB board is layed out with 6amp mcbs on the left and 32amp mcbs on the right. (Each room is served by 2 seperate mcbs 1 for lights (6amp) and 1 for sockets (32amp)

The hotel is requiring that the keycard switch will knock of all the power to the room (Sockets and lights).. which is what is causing me a few issues (if just switching the lights or sockets that would be easy but not sure of the easiest way to do 2 circuits as never fitted one of these beforel!)

Any help/suggestions greatly appreciated!

Contactor with one pole for lights and one for sockets? If keycard switch is rated for ELV only, contactor will need ELV coil and stepdown transformer to suit. Any fridges etc in room that need to be on 24h supply? If so you might have to split S/O circuits...
