Guest johnmiller Posted March 4, 2005 Posted March 4, 2005 Hi guys, I have a Scantronic 9851 which has two hard wired expanders on it. The alarm has gone off twice now over period of several months claiming a lid tamper on one of the expanders. The expander checks out fine and the wiring looks ok. The cable runs is approx 50m (outbuilding) though. I seem to remember a (firmware) problem causing the radio expanders to "disappear" but not the hard wired ones. Any ideas anyone? John
Guest johnmiller Posted March 6, 2005 Posted March 6, 2005 Is it remote from the panel in a box? if so the box lid tamper may be causing the problem. 42462[/snapback] Yes, it is 50m from the panel in an outbuilding. John
