Keyswitch Wiring – Single EOL Configuration
For maintained switches, connect the EOL
resistor for the zone at the keyswitch so that 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 11.

3- 2.2 kΩ resistor
4- Keyswitch (Open on circuit arms area)
For momentary switches, connect the EOL
resistor for the zone at the keyswitch so that the
switch shorts the resistor when it operates. An
open on the circuit produces an alarm if the area
is armed and a trouble if it is disarmed. See
Figure 12.

Keyswitch Wiring – Zone Doubled
Configuration
For maintained or momentary operation, wire the
keyswitch as shown in Figure 13.
