[mdibb2009]

Hi guys, as the title says, im wanting to fit a 12v drop bolt lock to my loft hatch, with a push to exit switch wired up in the cupboard below the loft space.

But.. im unsure of how to wire it up so im after some help please.

Obviously im going to need the lock and the push to exit switch, but will I need one of these :

And if so, how would I get power to that unit ?
And what cable should I use to connect up everything ?

Im fine with wiring it all up, just unsure of the best way to do it and the best material to use

Thanks very much for any help

Thanks for the replies.

The reason is that im wanting to store some quite expensive equipment up there and if anybody did manage to get into the house, I would want to make it as hard as possible for them to get into the loft which is why I thought this would be a good idea as obviously the lock would be hidden, aswell as the push button to open the hatch.

Thanks very much

Why not use a simple cable ( as in bicycle brake cable ) released bolt with the pull handle out of sight in a bedroom, perhaps in a fitted wardrobe.

As has been said take care to consider the situations which could result in someone being trapped in the loft in the dark. Lights in the loft should not be on the same MCB and/or RCD as the light lighting the are beneath the loft hatch.

Do burglars go into lofts?

Unless you're known to have good stuff to attract the attention of professionals (in which case they will get into the loft), aren't 99% of the rest twitching opportunist junkies looking for a very quick in and out with cash or something easily sold, not the sort who want to risk getting trapped in the loft whilst looking for expensive equipment?

Can this equipment be secured to the joists, or placed in locked enclosures secured to the joists?

Fit a fused spur beside a local socket and connect using 2.5 T&E cable. From the spur run a 1.5 T&E to the power supply. The negative of the power supply will got to one side of the lock, and the positive will go via your switch to the other side of the lock, you can use telephone cable or similar.

And a battery back up just in case.

If the intruders don't know about what is stored there, they won't even go into the loft.

If they do know and therefore are breaking in to steal the equipment, they will take the easiest and quickest option, which is to break a hole in the ceiling.

If the house is otherwise secure it's not impossible (especially in a bungalow) they'll go on the roof, lift a few tiles, and get in that way.

I agree - the OP has asked for advice on wiring not to be quizzed on if he is over engineering the situation , if you cant help with his query then just move onto the next topic..
