ANYBODY KNOW THE BOSCH B8512G OR B9512G FIRE ALARM PANELS?

I recovered a couple Bosch B8512G panels with transformers and keypads. I have one B930 programming keypad. I’d like to see default the fire panels and the password. Any way to do that from the B930 keypad? I don’t rea want to download any software to do direct connection programming or any internet programming.
Would like to do everything from the keypad if possible.
Please respond here or message me if you have any tips.
Thanks,

I have been learning how to use these panels for networking legacy panels to a receiver. The only way I know to reset the password (if you don’t have it) is to send it to Bosch to have it factory reset. You might get lucky if the original users used the default passwords.
