Any idea what has to be wired in to the lights to be able to control them via the output switches on the paradox alarm?

I'd assume some sort of wire from the alarm panel all the way to the lightswitch - but there must be something else needed to physically trip the light switch.

wouldn't it just create a parallel path to the physical switch, and the alarm will turn the act as a second switch to the light?

or used to activate a relay to control the light?

Hmm, what to write...

The outputs on a paradox are voltage free relays. They are certainly not capable of switching 230V and even if they could, maintaining physical separation between the extra low alarm voltages and the 230 would be difficult

You need to wire the onboard relay to a 230V relay or contactor with a 12V coil. the outputs of this need to be run to the light switch. Then you need to decide how it is going to control the lights. Will it override the switch? Do you just want to turn the lights on when you disarm the house and have the switch override the alarm at other times?

While not impossible to do it will be quite limiting and you might want to look into something else.

And of course like everyone else will chime in and say...this does require an electrician. It falls outside the homeowner exemption.

Yeah I did ask my electrician when he was there. I just didn't quite understand all the bits he needed. The light switch is actually in an annoying place that's not near the other outdoor lights.

Would probably make more sense to have the switch rerouted to a location nearer the other outside lights than hook it to the alarm.

As Mdooher has mentioned, you will need to use a relay to act as your "switch" it gets a bit tricky when you want dual control (Relay and wall switch)

Perhaps something like this?

The only thing I have done to my Paradox alarm is to run a wire from the alarm unit 'armed' output contacts to a LED in our garage door jamb so you can see the alarm state from the car/drive.

It's not hard at all, you just need the electrician to install a 12v SPDT relay that has 230v AC contacts

I have had this on my Micron alarm for about 10 years.

I have to admit I had to explain to the electrician how to wire it, he did not understand how relays work, in essence it is just 2 way switching.
Once he got his head around that it was a two minute job.
I had the alarm guy install the relay and the electrician connect the mains wiring.

I've used the Omron 12V DC 25A relay G7L-2A-TUBJ for doing this plenty of times for clients who want to control lights/outlets via tablets, smart phones etc. Use a 12V DC Supply from a simple cheap power supply with an inline fuse to be safe and you can put it all together in parts for less than $100.
