Program the keyswitch point with the zone code A91##.
If an onboard zone were used, enter A910A.
Expanded points would use the address of the expandion device followed by the loop code.
Keyswitch points always generate a trouble condition in the open condition while disarmed and an alarm condition when open in the armed state regardless of the setting of digit 3.
Shorting the point from a normal condition toggles the armed state of the panel.
