The Enable/Disable menu

Disabling a device
Caution: To prevent accidental alarms, only disable a device during scheduled
service or maintenance periods.
Use the Enable/Disable menu to disable a device. A disabled device does not
report alarms or faults (but logs them in the event log).
Notes:
A disabled device will activate any output configured as General Fault or Disable
to signal its non-functional status to the main fire alarm system.
If a disabled device loses power (due to a power failure), the device will be
enabled at power up.
Display modules in a cluster with any disabled device will also activate any
output configured as general fault.
A disabled detector continues to operate normally, but its events are not
indicated. For example, faults and alarms are detected but are not indicated (they
are added to the event log).
Note: When a detector is disabled, the detector Warning LED is steady and the
disablement is confirmed on the display module LCD.
To disable a device:
1. Select Enable/Disable from the Main menu.
2. Select and check the device that you want to disable or press F1 (Go To) to
search for a device by the device address.
3. Press F2 (Back) twice to return to the Main menu screen.
Enabling a previously disabled device
Caution: To prevent accidental alarms when enabling a previously disabled
detector, first ensure that the detector output level (DLevel) is lower than the fire
levels (Alarm 2, Alarm, Prealarm, Alert) – press F1 (Status) from the home
screen to view the device status details.
To enable a previously disabled device:
1. Select Enable/Disable from the Main menu.
2. Select and uncheck the device that you want to enable or press F1 (Go To) to
search for a device by the device address.
3. Press F2 (Back) twice to return to the Main menu screen.
