sixwheeledbeast Posted January 29, 2013 Share Posted January 29, 2013 Aren't those energy savings one nasty and noisy? While I agree it's unlikely to cause an alarm, I have seen optimas go into tamper when a light was switched on. Also extension speakers can click when the nearby light is switched on and off. The ring main is cleaner IMO. There's also the point above that the lighting circuit can trip if a bulb blows. Link to comment Share on other sites More sharing options...
norman Posted January 29, 2013 Share Posted January 29, 2013 The 4 x fluorescents in my garage would kill any alarm, off the ring main imo. Nothing is foolproof to a sufficiently talented fool. Link to comment Share on other sites More sharing options...
MrHappy Posted January 29, 2013 Share Posted January 29, 2013 Anybody care to explain how the noise on one circuit is prevented from appearing on all the circuits of the consumer unit ? Mr Veritas God Link to comment Share on other sites More sharing options...

jamez79 Posted January 29, 2013 Author Share Posted January 29, 2013 Thanks for all the replies. I'll avoid the lighting circuit just in case then and won't put it in the loft. I'll avoid the double knock feature too. Link to comment Share on other sites More sharing options...

Impedance, resistance is for direct current. (R = Z) The further away from the source of consumer RFI the better. Link to comment Share on other sites More sharing options...
