CEL Discovery - Intermittent Double Address Faults
#1
Blighted by intermittent double address faults.
They come and go and are restricted to a single loop.
Purely double address, no device missing faults.
The loop uses Apollo devices, mainly XP95 but there are a few Discovery.
The panel is a CEL Discovery with 4 loop cards fitted.
Any ideas???

I did have this once, could not for the life of me figure out what was causing it. In the end I ripped it out and fit a ctec ZFP panel. Didn't have a problem after that so I can only assume the Discovery panel was faulty. All I can suggest is if you have a spare panel lying around, bring it to site and dog it onto the loop, see if it behaves on a different panel.

It could be a possible rogue device I this on a Morley took me a little while to trace it to a faulty detector but changed the detector and cleared the problem

If I get an unknown device causing a double address I change a batch of detectors around on different loop
s to narrow it down.
Bugger, I did isolate the dialer...didn't I?

Had same on a Morley. Random double address faults.. Is there a diagnostic setting on the CEL panel ? Mine was a rogue heat xp95, once replaced, it was, ans touch wood, is still fine.
