connor2425 Posted March 5, 2011 Share Posted March 5, 2011 Need some help, I've got 12 gjd detectors to trigger 4 ptz's, the first 10 detectors work fine and wired with 2k2 and 1k eol resistors, the last 2 are wired exactly the same but will not secure, constantly in alarm!! What am I missing!!? Link to comment Share on other sites More sharing options...
Cubit Posted March 5, 2011 Share Posted March 5, 2011 You have checked the obvious haven't you? Belled the suspect ones out. Open/short circuit. Faulty unit? - it can happen. Link to comment Share on other sites More sharing options...
connor2425 Posted March 5, 2011 Author Share Posted March 5, 2011 Yes belled the cable out, it's fine. Got me stumped Link to comment Share on other sites More sharing options...
james.wilson Posted March 5, 2011 Share Posted March 5, 2011 Programmed right, have you proved the adpro hasn't got duff inputs? securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

connor2425 Posted March 5, 2011 Author Share Posted March 5, 2011 I'll check the inputs, is there any programming that could be amiss? Link to comment Share on other sites More sharing options...
connor2425 Posted March 5, 2011 Author Share Posted March 5, 2011 Haha didn't read that properly, I'll try the above Link to comment Share on other sites More sharing options...
PeterJames Posted March 5, 2011 Share Posted March 5, 2011 Haha didn't read that properly, I'll try the above Swap a faulty one with one of the working dets at the adpro, if the fault moves with the detector then its not programming, if the fault stays where it is it is programming Link to comment Share on other sites More sharing options...
connor2425 Posted March 6, 2011 Author Share Posted March 6, 2011 I've already swapped them out, not the detectors. I'll try changing the inputs see if it's them. If there was any interference down the line would it show a constant alarm? Ive shorted the pair and all fine, but if one of the cores is touching a unused core would it show it in alarm? Its going to be something simple! Hopefully for the help Link to comment Share on other sites More sharing options...

Hopefully for the help If it was interference then it would of moved when you swapped the detectors assuming that you swapped them at the Adpro like I said Link to comment Share on other sites More sharing options...
