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

D9412GV2/D7412GV2 Program Entry Guide (P/N:

F01U003636) 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 D9412GV2/D7412GV2

Program Entry Guide (P/N: F01U003636).

11.4.2 Programming

Refer to Point Assignments in the

D9412GV2/D7412GV2 Program Entry Guide (P/N:

F01U003636) 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 30 on page

61.

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 30 on page

61.

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 D9412GV2/D7412GV2

Program Entry Guide (P/N: F01U003636)

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 D9412GV2/D7412GV2 Program

Entry Guide (P/N: F01U003636).

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.
