14.2.1 Keyswitch Overview
You can connect a maintained or momentary contact
arming station to master arm/disarm any of the areas
in the system. The keyswitch is connected to an on-
board or off-board zone's sensor loop. Outputs can be
programmed to activate arming status LEDs for
keyswitch arming stations.
See Outputs on page 86 for more information.
14.2.2 Keyswitch Programming
See Options 1 for Zone Function Type 10 (Controlled
Keyswitch) on page 78 for programming information.

14.2.4 Arming/Disarming with a Keyswitch
The control panel offers a wide variety of keyswitch
arming options. See Options 1 for Zone Function
Type 10 (Controlled Keyswitch) on page 78 for
keyswitch arming configuration options.
14.2.5 Silencing Alarms with a Keyswitch
• Momentary Keyswitch: To silence alarms (stop
Alarm output), operate the keyswitch. If the area is
armed, operating the keyswitch to silence the alarm
also disarms the area. If the area is disarmed,
operating a momentary keyswitch to silence the
alarm does not arm the area.
• Maintained Keyswitch: If the area is armed, turn
the keyswitch to the disarmed position. The control
panel disarms the area and silences the alarm. If
the area is disarmed, turn the keyswitch to the
armed position (the control panel does not arm) and
then return to the disarmed position.
14.2.6 Exit Terminator Button
When the keyswitch is set to exit terminator, the input
functions as an exit terminator button (see Options 1
for Zone Function Type 10 (Controlled Keyswitch) on
page 78). This zone function activates in the same
manner as the momentary keyswitch. When Exit
Delay is active, operating the exit terminator button
terminates Exit Delay and immediately arms the
control panel. If Chime Mode is enabled and Exit
Delay is not active, pressing the exit terminator button
activates the chime time and the button functions as a
doorbell.
