But you have an enforcer better than the other old junk , euro panel and so , so forget the junk for collecting only and get something more
Em complicated , if you can master a dimension you can do any panel, I mean master it not blag it like me
It's a cr123 battery
Not easy to disable as there menu system is stupid
Pull wallet out call and engineer have it serviced and protect your home
Or rip off wall yourself and put in bin
In that case get a battery try it , see if it's charging ok, no need to take panel off wall unless it's fried in some way
Maybe if you got more budget get a panel that can also do some wireless circuits and so on
Scanteonic ion40 might do you great DIY panel ,, (init databasher)
Logan be serious
If your going to use it then yes , engineer should check it's power unit, replace battery, walk test check external internal sirens and make sure it works
Better to have some kind of park these days , then you could Lao get a quote for a new model , just depends on you, be preventative
