[QUOTE="Phoenix, post: 540299, member: 8133"] Ive seen similar a colleague went to look at a small shop installation because the alarm engineer had been getting false activations and the panel was reporting some kind of noise figure (not sure quite what, this was what he told me, but it was a proper commericial galaxy panel - so I guess it has things on it that you'd not see on the domestic kit) and they thought the issue started when new lighting went in. Applying an earth to the grid I think reduced teh figure (though not down to zero) and seemed to stop the issue. Though I think I did make the comment that if the alarm installer had not lashed the cables across the grid then there there would have likely not been an issue to start with.. [/QUOTE]
