Ge Concord Express 60-806 Missing Codes

["Les H" <lesesq@xxxxxxxxxxx>]

Hi folks,

I just moved into a house with a GE Concord Express 60-806 security
system and the former owner has none of the codes (probably never used
the system) or documentation.

Is it possible to retrieve these or codes or change to new ones with
the old ones?

I'm familiar with DSC systems and have done this but don't have any
background with GE systems.

Thanks,

Les
