IanHug Posted October 11, 2007 Author Posted October 11, 2007 what you wanting to do with it Ian? Still looking at picking up intruders before they access the house - when we're in the house not when we're out. So either linked to Chime or an internal alarm of some kind. Not particularly interested in CCTV, at the moment anyway. The back and side of the house would need covering. Might be possible to rig up a couple of photo beams - if they're more reliable than PIRs.

I'll give it a go then. Gives me the option to link them to the lights as well then and a sounder in the bedroom is all I'm after in terms of an "alarm".
arfur mo Posted October 11, 2007 Posted October 11, 2007 i to have installed many GJD systems and they are good if a fairly expensive option as you need at least one head, then the controler. obviously any lights have to be wired back to this. you can get floods with a plug-in chime module from City Electrical and i expect others, the link is via radio so you don't have any electrical phase issues costa bout the same as a GJD head but is a complete fitting with bulb. high end Risco have a radio version of their external Watch Out which claims ignores animals and moving tree's but picks up humans, if you want real fancy get a prosys panel when version 7 is released and yu cn tune the detector from software - cool! don't forget safe practice, your part 'p' and certification when ever messing with mains voltage regs alan If you think education is difficult, try being stupid!!!!
