Hi all - many apologies for the cross-posting but I should have posted in this area to start with.
OK this relates to one of those old 'British Gas' versions of the DSC 5015 panel, with the 'V2.81 BG' firmware.
I got an engineer out recently to help me default the panel for me and reset the installer and master codes. All fine, and I've been successfully entering/using programming mode via the *8[installer code].
But last week I decided to fully power down the system (AC + battery) while I did some work on the wiring; and now when I try to enter programming mode with '*8' it just does a 3-sec error beep as soon as I hit '8'.
Everything else works fine, so I'm assuming there must be a user command with the master code, in order to enable installer access...? There is no mention of anything like that in the v2.2 installer manual, so I'm presuming it's another customisation by those very nice British Ga$$$ chaps ?
I've tried set/unset (using master code); view/clear alarms; view/clear trouble; full system test (with master code) and complete power cycle but no dice.
Only other thing I can think of is to hardware default the panel. I know how to do that, I know the BG default installer code, and I've previously removed the installer lockout option... But I don't want to do that if it's going to leave me in the same situation!
Any clues please??
