Guest Jaspar Posted January 11, 2006 Posted January 11, 2006 Hi. I hope someone out there can help me?! Am just installing a new home alarm. My problem comes when I unset the alarm after setting it up. Passing any of the PIRs activates the alarm with a tamper error. I damn sure I've got the wiring right, and have even tried jumpering the tamper terminals at the control box end. The people at Nexus weren't much help, but I tried returning the panel and getting a replacement, same problem. Thanks in advance, Jaspar
cdosrun Posted January 11, 2006 Posted January 11, 2006 Jaspar, It does sound as though you haven't wired the alarm panel up correctly. I am sorry if the following question insult your intelligence, but it is probably better to start with the simple things first. Are you wiring one sensor to each zone in 8 (or 6) core cable? Your panel supports Double Pole wiring for each zone, so when the tamper alarm goes off, does the alarm tell you which zone has tampered? What sort of PIR sensors do you have, or what are the markings on the terminals? It does sound as though you have crossed the alarm and tamper wiring. If you have a multimeter, disconnect the zone wiring for one PIR (just the AA terminals on the panel) and whilst reading resistance, have someone walk in front of the PIR. The resistance should go high, if not, open the case of the PIR, if it goes high now, you know you have cross-wired the Alarm and Tamper wiring. If not, link out all the zones bar one PIR zone. So, short the A-A and the T-T for each PIR zone. Then only wire the alarm (AA) for one zone and run a walk test. Does it trip when you walk in front of the sensor or open it?

Guest Guest Posted January 11, 2006 Posted January 11, 2006 Hi Andrew, thanks for the response. It does sound as though you haven't wired the alarm panel up correctly. I am sorry if the following question insult your intelligence, but it is probably better to start with the simple things first. Don't worry about me getting offended, I'll take any help I can get! Are you wiring one sensor to each zone in 8 (or 6) core cable? Yes, one sensor per zone, 6 core. Your panel supports Double Pole wiring for each zone, so when the tamper alarm goes off, does the alarm tell you which zone has tampered? Yep, it's whichever of the PIRs I walked in front of. What sort of PIR sensors do you have, or what are the markings on the terminals? It does sound as though you have crossed the alarm and tamper wiring. They're standard PIRs from a company called response (available at most good hardware stores. The terminals are both labeled and colour coded. I've triple checked the wiring and they're all correct: N/C (blue/yellow) -> A (Alarm) 24hr (green/white) -> T (Tamper) red and black to + and - If you have a multimeter, disconnect the zone wiring for one PIR (just the AA terminals on the panel) and whilst reading resistance, have someone walk in front of the PIR. The resistance should go high, if not, open the case of the PIR, if it goes high now, you know you have cross-wired the Alarm and Tamper wiring.If not, link out all the zones bar one PIR zone. So, short the A-A and the T-T for each PIR zone. Then only wire the alarm (AA) for one zone and run a walk test. Does it trip when you walk in front of the sensor or open it? Unfortunately, I don't have a multimeter. I have tried disconnecting the tamper and bridging the T connections at the control box for the zone in question. The tamper still activates for that zone when the PIR is trigger in unset mode. I haven't tried bridging A-A, but am not sure if that would prove anything? Andrew Once again, thanks for taking the time to respond to me. Jaspar
morph Posted January 11, 2006 Posted January 11, 2006 Prove the panel first, before doing anything else. 1. Disconnect all the wiring from each Zone (alarm and Tamper). 2. Fit a link on each zone One on tamper and one on alarm. 3. Close the panel lid and check the if the system is clear and sets. If the faults clear then its your wiring, refit each detector one at a time 4. If the fault still exists its one of two things The bell wiring or the lid tamper. Do the above and come back to us with your findings.

Do the above and come back to us with your findings. I'm willing to try this, but I'm not convinced it will round down the problem, as the alarm already clears and sets. The display tells me exactly where the error is, which in this case is zone two or zone three (the PIRs). The sytem unsets quite happily with no errors. It's only when I walk in front of the PIRs that the tamper is activated. It's as if the opening of the alarm loop by the PIR is for some reason setting off the tamper for the zone (even if the tamper connection for the zone is bridged at the control panel). Thanks, Jaspar
cdosrun Posted January 11, 2006 Posted January 11, 2006 Ok then Jaspar, just a silly question, have you programmed the zones for 24hr? I really would do as Alarmgard suggests...trust the pros.

morph Posted January 11, 2006 Posted January 11, 2006 Without wishing to be rude, your stuck, you come on an internet forum asking for help, we have advised what to do, its good advice. We fit alarms for a living, biggest cause of faults "Customer Error" If you work with us, we can help you, if you dont your on your own. This was not meant to be offensive, but getting back to basics is often best. Colin.
Guest Guest Posted January 11, 2006 Posted January 11, 2006 Ok then Jaspar, just a silly question, have you programmed the zones for 24hr?I really would do as Alarmgard suggests...trust the pros. Andrew I'm not sure what you mean by that? Isn't 24hr just the same as tamper? The alarm doesn't seem to have any settings for the zone connections beyond when and how they're activated. I'll go with Alarmgard's suggestions this weekend, and see how it goes. I have a feeling that it's probably another faulty alarm control, as I've checked all the wiring thoroughly, and even the guy from the support line for the alarm couldn't come up with an explanation, he just suggested I take it back to the shop. Thanks, Jaspar
Guest Jaspar Posted January 11, 2006 Posted January 11, 2006 Just read the last post. Sorry I didn't mean to offend, Colin. I was just clarifying the fact that that I've isolated the problem to specific zones, and have checked the wiring thoroughly. I will do as you say as soon as I get an opportunity where I'll not be annoying the neighbours! Thanks, Jaspar
