Galaxy g2-20 alarm problem

[mrbearuk]

I have recently got hold of a used Galaxy 2-20 alarm system. The default user code (1234) works but the engineers default code (112233) does not. Is the away to reset the system to factory reset mode.? Thanks

Typically most alarm boards have a way to default to factory mode, typically be shorting 2 jumpers marked on the board while depowered and then connecting the battery, and opening the jumper after about 20 seconds. Disconnect the siren while doing this, as it probably will go off. Then you will be able to use the default codes.
