D268/D269, D279 Independent Zone Control

You can program on-board points 2 to 8 so the D268's, D269's, or D279's (or later versions') Independent Zone Controls
(IZC) operate as independent point controls (arms and disarms the point).
See Point Index Configuration in the D6412/D4412 Program Entry Guide (P/N: 45351) for programming information. See the
installation literature that accompanies the D268, D269, and D279 (or later versions) for wiring and operation instructions.
To use the D268's, D269's, or D279's (or later versions') IZC, you must program the panel's on-board points for
1 k Ω Ω Ω Ω Ω EOL resistors. Points 2 to 8 must all be supervised with 1 kW EOL resistors, even if an IZC is only used for one
point. See Global Point Configuration in the D6412/D4412 Program Entry Guide (P/N: 45351) for programming
instructions. Only use on-board points 2 to 8 with an IZC. No EOL resistor is used on the points connected to the
IZC.

can be programmed to activate arming status LEDs for keyswitch arming stations. See the Outputs section of the D6412/
D4412 Program Entry Guide (P/N: 45351) for more information.
