The 862 8 zones - 6 programmable & 2 fixed as 24hr zones. The zones that are flashing are showing the history of what happened last time the panel was armed. So zones 1,2&5 caused the panel activate last time it was armed. These can be cleared by arming & then disarming the panel. Hence last time it was armed nothing happened. If zone 4 is permanently on then it is unsealed , you need to find out what zone 4 is & fix the problem.
Fault 1 is Backup battery fail - this is tested on arming
Fault 2 is time /date - obviously all power has been removed at some stage.
Fault 4 is horn speaker fail.This monitors a small current in the horn wiring & detects an o/c. This can be disabled at location 424 but the cabling thats causing it will still need to be fixed.
Fault 8 is comms fail so this panel has previously tried to report to somewhere unsuccessfully. If reporting is not required it can be disabled at location 177
IMO if you are across security programming techniques then default it & start from scratch , at least then you will know that there will not be any hidden nasties in there.
