SL compact house alarm problem

[sefuss]

I recently did some wiring modifications in my house and had to switch the power on and off a few times
This set my alarm off and sent it a bit funny
Now that the wiring mods are complete i could not re enter my code but i have managed to reset my alarm with the manufacturers code 0123 and it works well but how can i re program my alarm so it has a code that i know rather than 0123
Thanks in advance guys

You may need to reprogram the system as it looks like it's gone back to factory set .. Change your code first then fully test all items on your system. Replace the back up battery as they can burn out a resistor on the panel if faulty. Google optima g3 for user guide.
