Why is my Bosch AMAX panel 2100 Control Panel keypad not responding and making a wrong tone when I press any key?

If your keypad is not responding and you hear a wrong tone when pressing any key, it could be due to abnormal RBGY wiring, the keypad being locked after entering incorrect passwords multiple times, or an incorrect jumper setting when using multiple keypads. Try reconnecting the RBGY wiring. If the keypad is locked, wait for 3 minutes before trying again. If you are using multiple keypads, reset the jumper referring to the information on keypad address settings.
