Radioncs 9112 lockcode

[Logan <mcoinvestmentnospam@xxxxxxxxxx>]

Good evening all,
 I just got a Radionics 9112 panel, first thing I did was lock the reset
pin and try to check for a lockcode with my 5200. Of course it was locked!
Is there a way to zap the code back to default, such as by removing the
coin cell battery? Are there certain lockcodes that people use a lot, like
54321 or 11111 or something that I might want to try? One other thing, is
there a way to use a D1252 on that panel in an unsupervised fashion, such
as on serial bus?

Any help is appreciated,
 Logan
