Clearing Alarms
Clearing a console of alarms is important because, depending on how the T5 Series FMS console has been set up,
alarms can: disable channels, start an annunciator, or stop a line test under way.
Administrator privileges will be necessary to clear line alarms on the T5 Series FMS console. For instructions on how to
obtain an Administrator access level, please refer to the T5 Series FMS Programming Guide (p/n 000-2142) or the TS-
550evo FMS Programming Guide (p/n 000-2173).
1. Identify the alarm on the FMS Alarms screen.
2. Diagnose the condition using information found in the Alarms chapter of this guide.
3. Follow the troubleshooting steps in the previous section of this chapter to correct the issues indicated by the alarms.
4. Navigate to the Line Control screen.
5. Select
Reset Alarms on the Control screen.
6. Select Enable/Disable on the Control screen if you were not given the choice to enable the line when the alarms were
reset.
If the condition still exists, the alarm can take up to several hours to reappear after the line is enabled.
