11.3 D279A 
Independent Zone Control 
Any on-board or OctoPOPIT point can be programmed so that the D279A Independent Zone Control operates 
as independent point control (arming and disarming the point). 
Refer to Point Assignments in the D9412GV3/D7412GV3 Program Entry Guide (P/N: F01U170807) for 
programming information. Refer to the D279A Operation and Installation Instructions (P/N: 46458) for wiring 
and operation instructions. 
11.4 Keyswitch 
 
11.4.1 Description 
A maintained or momentary contact arming station (keyswitch) can be connected to master arm or disarm any 
of the areas in the system. The keyswitch is connected to an on-board or off-board point’s sensor loop.  Relays 
can be programmed to activate arming status LEDs for keyswitch arming stations. Refer to Relays in the 
D9412GV3/D7412GV3 Program Entry Guide (P/N: F01U170807). 
11.4.2 Programming 
Refer to Point Assignments in the D9412GV3/D7412GV3 Program Entry Guide (P/N: F01U170807) for the 
correct programming for points used for keyswitches. 
11.4.3 Installation 
For maintained switches, connect the EOL resistor for the point 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. Refer to Figure 29 on page 58. 
For momentary keyswitches, connect the EOL resistor at the keyswitch point so that when the keyswitch 
operates, it shorts the resistor. An open on the circuit causes an alarm if the area is armed and a trouble if it is 
disarmed. Refer to Figure 29 on page 58. 
11.4.4 Operation 
Maintained Contact 
If the point to which the keyswitch is connected is programmed for a maintained contact, an open on the arming 
circuit arms the area. All faulted points are force armed, regardless of the entry in the FA Bypass Max program 
item. Returning the circuit to normal disarms the area. Refer to Area Parameters and Point Assignments in the 
D9412GV3/D7412GV3 Program Entry Guide (P/N: F01U170807).
