Keyswitch Installation

For maintained switches, connect the EOL resistor for the point at the keyswitch so the switch opens the circuit when it
operates. A short on the circuit produces an alarm if the area is armed and a trouble if it is disarmed (see Figure 34).
For momentary switches, connect the EOL resistor for the point at the keyswitch so the switch shorts the resistor when it
operates. If the area is armed, an open on the circuit produces an alarm; and when the area is disarmed, an open on the
circuit produces a trouble (see Figure 34).

Keyswitch Operation

Arming/Disarming
The panel offers a wide variety of keyswitch arming options. See Point Index Configuration in the D6412/D4412 Program
Entry Guide (P/N: 45351) for details on configuring keyswitch arming options.
Silencing Alarms
• 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 panel disarms the
area and silences the alarm. If the area is disarmed, turn the keyswitch to the armed position (the panel does not
arm) and return to the disarmed position.
