norman Posted October 26, 2012 Share Posted October 26, 2012 The Aritech one has a plastic key-like fastening on the bottom, you turn it 1/4 turn and then pull it out completely iirc. And I would agree with James ref the 400, fitted hundreds of these, great DT. Nothing is foolproof to a sufficiently talented fool. Link to comment Share on other sites More sharing options...
antinode Posted October 26, 2012 Share Posted October 26, 2012 We have a few sites out there with some old school C&K detectors (8140, 8225, DT435 etc). Can't say I've ever known one cause a problem. Am I right in thinking that C&K were the first company to manufacture/patent a PIR/MW dual tech? Trade Member Link to comment Share on other sites More sharing options...
