11.3 D268/D269 Independent Zone

Control, D279A Independent Zone

Control

Any on-board or OctoPOPIT point can be

programmed so that the D268/D269 or 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: F01U003636) for programming

information. Refer to the D268/D269 Operation and

Installation Instructions (P/N: 74-004758-000) or 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 25.

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 25.

Use 1 k

EOL resistors if using one of the zones on the control panel or an OctoPOPIT. Use a 33 k

Ω

resistor if using a POPIT.

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
