Staircase timer module & press switches

I need to replace some pneumatic time lag switches in a stairwell as they're constantly failing and am looking at installing one of these - http://www.tlc-direct.co.uk/Main_In...tum_Old_Range_Index/CMD_Controls_3/index.html - and 4 of these - http://www.tlc-direct.co.uk/Products/MKK4878P.html - instead.
How are they wired up, is it simply a matter of a switched line to each press switch then the module installed on the load side of the circuit with a permanent line?

Cheers

As far as I know, you just feed 240v to all 4 switches, then wire the outputs from the switches to the timer module. Each time you press a switch while it is on, it resets the timer to its full programmed time.

Dont forget an enclosure for the timer.

It's not rated for a very big inductive load, so you might need to use a contactor with it too.
