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 D7212GV2 Program

Entry Guide (P/N: F01U003804) 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 D7212GV2 Program Entry Guide

(P/N: F01U003804)

11.4.2 Programming

Refer to Point Assignments in the D7212GV2 Program

Entry Guide (P/N: F01U003804) 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 23.

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 23.

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 D7212 Program Entry Guide (P/N:

F01U003804)

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

D7212GV2 Program Entry Guide (P/N: F01U003804).

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.
