andytpickering Posted January 18, 2014 Share Posted January 18, 2014 Having searched numerous forum posts I'm at a total loss, so I thought I'd try asking... I have a Honeywell Optima Alarm system (8EP396A panel with a 8EP417A LCD Keypad and a single PIR sensor) for my shed. When I entered this morning and entered the code the alarm sounded but every time I entered the correct code the alarm would briefly stop and then sound again. the only way I found to stop it is power it down and remove the battery. I only have about a second to see the fault, which is coming up as a PA fault. but the PA connection on the panel has a link cable closing the system (I assume this means it's not in use?) I've tried doing a reset of the system, but nothing seems to work. As soon as I power it back up the alarm sounds again Any help would be greatly apreciated Quote Link to comment Share on other sites More sharing options...

andytpickering Posted January 20, 2014 Author Share Posted January 20, 2014 been through them all again today, but no joy. the system has worked flawlessly for the last couple of years so I can't figure out what could have happened. Quote Link to comment Share on other sites More sharing options...
admin Posted January 21, 2014 Share Posted January 21, 2014 Could be a dry joint on the pcb terminal block. Also check both sides if the board for corrosion. O guess the shed isn't heated etc? Quote Link to comment Share on other sites More sharing options...
andytpickering Posted January 22, 2014 Author Share Posted January 22, 2014 checked for corrosion and there doesn't appear to be any. it's more of a summer house than a shed so it is fully insulated and heated as it get used a few times a week. what I can't understand is why it happened just when I entered the code, if there had been some kind if break in the PA circuit I could have happened at anytime whilst it was set.

admin Posted January 23, 2014 Share Posted January 23, 2014 Yes bit using the keyboard may flex the board slightly. There is only that pa circuit so if the link is good it must be the board. Quote Link to comment Share on other sites More sharing options...
