many thanks martin

post make and model of control panel would help no prizes for guessing guys). most likely the system needs down powering and then restarting with a decent battery installed, but that is really is a job for a competent engineer for your own safety

What your question though Martin??????

I would reckon Martin is referring to the fact that the buttons are not operating after the power failure,non??

NO!, clearing the VM will also clear al the programming back to factory default, so if the installer has changed things then those settings will be lost along with all the codes.

the keypad and main control unit are both microcomputers in their own right, but need to be in sync to be able to communicate, thats why powering down and again then powering up in the proper sequence is very important, the manual you have should relate to it and what the manufacturer suggests is the correct method.

as an example, if the battery is fully discharged actually duff, it might apply say 10 not 12 volts when reconnected, the keypad may respond but the main cpu might suffer or vise versa, so starting up on the battery can cause problems you might not expect.

some panels do clear their memmory which they should not on power failure, that why i asked the make and model.

the sequence for power up is mains first then battery on that panel,

rather daft as the problem you had of a power down is fairly common (so a very 'p' poor poor design imo)
