Momentary Contact
If the point to which the keyswitch is connected is programmed for a momentary contact, shorting the arming
circuit toggles the area's arming state between armed and disarmed. All faulted points are force armed,
regardless of the entry in the FA Bypass Max program item. Refer to Point Assignments in the
D9412GV3/D7412GV3 Program Entry Guide (P/N: F01U170807).
Silencing the Bell
To silence the bell (stop Alarm Bell output) if the system is armed, position the keyswitch to disarm the area. If
the area is disarmed, turn the keyswitch once to start the arming process. Turning the keyswitch a second time
stops the arming process and silences the bell.
