I am thinking of installing floodlamps around my own house, 3 x 500watt halogen ones. What is the best and most efficent method of wiring this to my existing alarm panel ? (veritas r8). do I need some sort of controller? Or can i simply trigger a relay off the intruder output to switch the live? any suggestions appreciated please.

I did the same thing for a customer once 4x500 watt floods pulsed on/off (20secs/5secs). But simply switching a diode protected 12v mains relay from the control panel worked a treat in the 1st instance.

great, so i just need a normal 12volt relay then with built in diodes?

use octal based relays from rs.

The opinions I express are mine and are usually correct!

(Except when I'm wrong)(which I'm not)

Yeah you can buy them with the diode in, or just supply your own. Its just to stop any back EMF from the relay coil.

Just need to make sure you get a relay over-rated for the job, that can easily switch the wattage you require.

I always swap the 500's for 300's and there never seems to be much difference in the output for a 40% drop in power consumption
