D9412GV2/D7412GV2 Operation and Installation Guide 11.0 Arming Devices

11.3D268/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.

11.4Keyswitch

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