Moved into new house where this alarm is fitted but after some building work front door magnetic sensor was detached from door frame and left and alarm indicated some fault. I re-connected it but I get an error that I need to contact the installer.

I don't know who installed it and I have no other pass codes apart the single user code we were given.

I can re-programme the panel if I knew how to reset it first.

Can someone help me to reset the panel, thanks.
