Hi,
Looking for info on how to control access to a light switch in a communal hall. It is 2 way and fed from one flat only. The flat owner wants to control use of the light. I have seen a keypad used but no idea who made it.
Anyone got any ideas?
Thanks
 
I would have thought the better option would be to replace the existing switches with time-lag switches so that light only stays on for pre-set time.

By creating such an override switch as you are suggesting there is the potential for accidents to happen as a result of the light having been switched off, which then leads to questions of liability and all that stuff.
 
Time-lag switches for use if needed during daytime.
Photocell over-ride so lights are on at night. That's the normal way I have done it for several apartment developments/.
 
Thanks everyone for the replies. The house has been converted into two flats hence the reason why lights are fed from one. I think at some point each flat had a light that they could switch on in the hall but looks like someone has been altering things.
I will look at the time lag switch option and see what I can find.
Can anyone recommend a manufacturer?

Just stay away from the vacuum type as people tend to smack them in or wedge something down the side. I personally think time lag switches are a little old hat and would probably just change the fittings to something with an integrated PIR and isolate the switch drops.
 
You can get a switch PIR for your situation it does not require a neutral so easy to replace ordinary switch. The problem with them on a two way circuit is that they want to be wired a different way to two way switching.They have to be daisy chained type of wiring.

I didn't know about no-neutral pir, so I had a look in TLC and link is below. The unit draws power by passing a small current through the load when in the off state. When it turns the load on, there is a little rechargeable battery that takes over. Interesting ...

Danlers make them as well.
