Alarm Siren box connected to lighting circuit

Hi All

Need some advice, i am looking to power my burglar alarm siren box by hard wiring to the lighting circuit in the attic. The siren came with a ac/dc 12v plug but i was thinking of spurring off the light, adding a fused spur and then connecting to a 240v to 12v transformer (cutting the plug off and using the wire to connect to the transformer).

Is this at all doable? or just a recipe for disaster. Is there any other way i could get around connecting the siren box? I want to avoid running wires down the front of the house and also drilling into the bedroom to plug into a socket. The attic seems the most effective way 

Any help/suggestions would be much appreciated

they are usually hard wired to the alarm control panel...

Hi, thanks for the reply, I forgot to mention it's a wireless alarm system

then a suitable fused spur from lighting circuit as you describe would be adequate. you could just fit a socket and plug it in, but mark the socket as being for transformer only and connected to lighting circuit

Thanks Andy, that's an idea actually. Would I be able to wire the socket on a 1.5mm cable? As far as I understand only a 2.5 should be used on sockets but not sure how that would work off a lighting circuit using 1.5 cable. I could possibly run a 2.5mm up the hollow wall from the bedroom sockets and spur off that too

What you do is get an electrician to install a socket where you need it. 

Wouldn't have come on here if that was going to be the case

So you want step by step instructions from people who are trying to earn a living doing this work............

no mention of a step by step, perhaps you should go read back what I wrote before commenting

I read post # 5 - enough said.

ha! Doesn't seem like a step by step to me. Not like I'm asking to re-wire my house is it. But anyways thanks for your 2cents

No but the factyour asking wether a supply can be takenfrom where you want shows little knowledge wether something is safe or not (shakes head)
