EST3 System Operation Manual 2.11
Disabling hardware components
Disabling a hardware component isolates the component from
the system. While disabled, a component’s state changes are not
processed. For example, if a disabled smoke detector changes to
the alarm state, the panel will not go into alarm. The panel will
go into alarm if you enable the disabled smoke detector and the
smoke detector is still in the alarm state.
Hardware components include:
• Devices (input and output circuits, detectors, and modules)
• Rail modules
• Buttons
• LEDs
When you disable a hardware component, the 3-CPU1 lights the
3-LCD Disable LED and places a Disabled Active event in the
trouble queue.
Note: To disable a component you need the component’s logical
address. You can get component’s logical addresses from an
SDU Objects report.
To disable a hardware component:
1. Press the Command Menus button , then choose Disable.
2. Do one of the following:
• Choose Device to disable: input circuits, output circuits,
detectors, or modules
• Choose Card to disable: rail modules or control / display
modules
• Choose Button to disable: control / display module buttons
• Choose LED to disable: control / display module LEDs
3. Enter the target component’s logical address.
4. If prompted, enter a valid user access level password.
