Our alaram system lost it's time after a recent long power outage. No it arms itself at 5 in the afternoon. I need to reset the clock.
I have tried following the instructions in the manual on the Honeywell site:
type X X X X (master code) + # + 6 + 3 but nothing happens.
This alarm is not monitored so to get the installer to reset it would cost $95. Is there any reason we should not be able to do this ourselves?
The problem is although I have a security code I'm not sure if it is the Master Code
