    How to troubleshoot missing alarms on points connected to the D222A keypad.

    • Missing alarms on hard wired zones that are connected to keypad expansion will occur if the keypad loses power.
    • If the keypad loses power the expansion points connected on the keypad are not able to report status to the panel thru the data wire connection.  The result is ANY points programmed  and addressed to the keypad with out power will be reported as a missing alarm.
