10.3D279A Independent Zone Control

Any on-boardor OctoPOPIT point can be programmed so that the D279A Independent Zone Control operates as independent point control (arms and disarms the point).

•See the Point Assignments in the D7212G Program Entry Guide (P/N: 4998138538) for programming information.

•See the D279A Operation and Installation Guide (P/N: 46456) for wiring and operation instructions.

10.4Keyswitch

10.4.1Description

A maintained or momentary contact arming station (keyswitch) can be connected to master arm/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. See Relays in the D7212G Program Entry Guide

(P/N: 4998138538).

10.4.2Programming

See Point Assignments in the D7212G Program Entry Guide (P/N: 4998138538) for the correct programming for points used for keyswitches.

10.4.3Installation

For maintained switches, connect the end-of-line 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. See Figure 18.

For momentary switches, connect the end-of-line resistor for the point 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 18.

10.4.4Keyswitch 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. See Area Parameters and Point Assignments in the D7212G Program Entry Guide (P/N: 4998138538).

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. See Point Assignments in the D7212G Program Entry Guide (P/N: 4998138538).

Silencing the Bell

To silence the bell (stop Alarm Bell output) if the system is armed, operate the keyswitch to disarm the area. If the area is disarmed, operate the keyswitch once to start the arming process and a second time to stop the arming process and silence the bell.
