Hi,

I just moved into a new home with a FBII XL-21 alarm system. Previous
owner didn't leave me any information about the code and the alarm company
that they used no longer in business.

I have tried reseting the system and was able to reset the master user
code. However, I can't program the alarm because the default installer
code doesn't seem to be working. Perhaps it has been changed or being
locked out using software. Is there a way that I can override the previous
installer code or reset it?

Your help is greatly appreciated.

Contact a local alarm company, they "may" be able to unlock it for
you but I'd suggest that you get a real alarm system (panel). The
company that you call is likely going to suggest that you change the
panel though. You might think that they're just trying to get you to
spend the money on new equipment however, the XL 2 series panels where
ok but they were really low-end equipment. Most alarm companys that I
know would probably suggest that you change out the panel anyway, even
if they could unlock it for you. To give you some idea of the
value .....If I remember right, that panel sold for about $39.00,
dealer price. Even if I weren't in the business, I'd want something
better than that protecting my property and family.

Really, get a new panel installed.

Either you are using the wrong default program code, or you have a LCD
keypad, which requires you to push a few more keys to access programming.

I followed the installer's manual to reset the system and was able to
use the default master user code, etc.

I have a LED panel and the default installer code just wouldn't work.
Either I mis-identified the model, which so happen to be able to reset
using the same method or the installer code is locked, because this
model does have that capability, according to the manual.

thanks!

Then you may have a custom version of the XL2. It's defaulted alright, but
the installer code is something else altogether. I ran into one where the
default code is 2468.

It's cheaper to get a new board.
