Have tried everything in manual under trouble shooting. Alarm will not set have done all e.g the walk test, strobe test etc. etc. But when we try to set it always highlights zone 3 and beeps 9 times. We have link tested the detector in zone 3 and does not appear to be a fault but the red sensor light does not come on in zone 3. Have tried programming to omit zone three (but will not work) and when we try to set alarm it still lights zone three up on control panel and beeps 9 times. (9 beeps according to manual says problem with tamper switch, we have removed control panel cover and the cover on sensor three and have stretched springs on tamper button as per manual for these to reset but still can not set alarm- anyone have any idea's?? Everything else works fine when we test thanks

More info, as before check the cable to zone 3.
Or link out the zone again, trace back its tamper and link that from the global and see what happens.
It will set, but you still need to repair the old cable to get zone 3 back or run a new cable.

Any DIY work done, a new carpet?

By the way, why 3x posts about the same problem, stay in one, HERE, it makes life so much easier. Add a supplementary question.

Other detectors LEDs showing as expected?
Checked the cable with a meter? Sounds as though it's damaged, done any work?
Where were you and what were you doing the 1st time the tamper sounded. Think back.
Checked fuses?
