Disabling and enabling zones
Zones are typically disabled while maintenance is performed to prevent event messages
originating from the zone from being displayed, printed, or reported off-premises. Disabling a
zone does not prevent activations in the zone. All devices in the zone continue to function
normally.
Note: Remember to enable the zone as soon as you have finished working with it. Resetting
the panel does not restore disabled zones. These must be manually enabled and then
restored.
When you disable a zone:
• The common Disable LED turns on
• On a zone/device system, the LCD displays disabled messages for the zone and all of the
devices in the zone
• On a zone only system, the LCD displays a disabled message for the zone
• The common trouble LED flashes and the panel goes into a trouble state
• The common trouble relay changes state
• The disabled and active points indicators on the LCD increment
• If you are using an LED display expander, the zone LEDs blink for the disabled zone
• Resetting the panel has no effect on a disabled zone, but removing all power from the
panel enables the zone
• If the zone you are disabling contains devices that are active, a warning message is
displayed

1. Press the Menu button and choose Control.
2. Enter a level one password.
3. Choose Enable/Disable.
4. Choose Zone.
5. Select the zone that you want to disable or enable.

7. If devices in the zone are active, acknowledge the warning message by selecting Continue
to disable the zone or Cancel to exit.
