MattB Posted April 25, 2020 Share Posted April 25, 2020 (edited) Hi - I moved into my house about 18 months ago and the existing alarm system showed no sign of life. Along comes the virus so I'm thinking it's a good time to try and get it fixed. After a bit of looking around, I bought a new CP8L control box, battery and panel. Disconnected the existing board, replaced and rewired everything up to the existing IR devices and the bell. After powering up, and entering the default engineer code I get a message that says 'cannot set zone 7' and then after entering the code again and the alarm going off, I get the !!!CHECK!!! zone 7 code. Having walk tested all 8 IR sensors I do get a red led from each sensor as it is activated. I can narrow down which IR is 'zone 7' based on where the wiring goes from the control box, but I cannot be certain which one it is. Ideally I'd like to fix the issue related to the zone but in the first instance I'd like to delete zone 7 to try and arm and test the system further - but I can't get past the initial menu options to access the delete zone option. Any ideas? Obviously, I'm a novice here... so grateful for any help! Shall I just disconnect AZ7 +- wiring from the board? Thanks - Matt Edited April 25, 2020 by sixwheeledbeast Removed codes Quote Link to comment Share on other sites More sharing options...
sixwheeledbeast Posted April 25, 2020 Share Posted April 25, 2020 Remove zone from the PCB replace with a link and test the circuit with a multimeter in the meantime? Quote Link to comment Share on other sites More sharing options...

Doesn't seem like a controls issue to me. Quote Link to comment Share on other sites More sharing options...

You'll need to be absolutely sure which zone is connected to which sensor(s)* before continuing. Also, do the detectors have resistors wired in the terminals? *Should be one detector per zone, but older systems may vary. To be honest, the CP8L was a poor choice given the competition, but I guess you're stuck with it now. In use it isn't much different to many but is a bit quirky to say the least with some of the setup.

aissecur Posted May 23, 2020 Share Posted May 23, 2020 Hi, zone 7 factory setting is PA (personal attack), if this is not a pa zone then program it to what it is (12hr, EE etc) Quote Link to comment Share on other sites More sharing options...
