Been having problems since I had the power cut off so I changed the internal battery
The alarm sets now and when I return home put the code in to cancel it just doesn’t do anything and activates the alarm.
To silence it I have to enter 4321 & reset
The company that installed have gone bust and nobody seems to know what I can do...
maybe a full reset ? Please if anyone can talk me through this or put me in touch with a engineer that can? I’m in St. Helens area NW
