I've been asked to install some security lighting at a private dwelling, but the client only wants it to be activated when the alarm is set. I'm assuming, or rather hoping, that the alarm panel has some form of switched output when the alarm is set. Do most panels have this? (I'm not sure as yet as to the make/model of this panel) 

Also, can anyone suggest a relay to use so that I can switch on the 240v security lighting when the alarm is set? 

 

thanks.....

it would depend on the panel but you could use the set output to switch a mains rated relay which would then energize the lighting circuit. 

Thanks, I'll take a look at the panel when I'm there next week. Would one of these do the job or is there a more 'professional' version? http://www.ebay.co.uk/itm/like/121950780746?ul_noapp=true

You are going to need to know:-

What the alarm system is and if there is an output available for that.

What the lighting is, how it is wired and how much load the lighting is. A simple mains relay may fail switching heavy loads.

The lighting is just a couple of 30W led fittings, so only about 0.2A

I'll check the panel to see if it's suitable...

Depending on how your wiring this up you do not want a 12v relay you need a 240v relay.

 

You mean 12v relay with  240v 5a contacts to switch as an example

 

In short yes, could have worded it better lol
