Figure 13 - All Alarm Parameters Supported by Epoch-M1P
In the event of a hard fail alarm, the control board will shutdown the HPA (both
uplink & downlink) for 30 seconds and then turns on the HPA to check for a
repeated hard fail occurrence. If the hard fail alarm is persisting up to four
consecutive occurrences, the control board will shutdown the HPA for 20 minutes
(total of five consecutive hard fails). After 20 minutes, the HPA will automatically
come back alive and the control board will check if the Hard Fail alarm has cleared.
If it has not, the same process will continue as mentioned above.
** The alarms can also be viewed on the front panel of the repeater by clicking
the VFD button. Please refer to Appendix B for more detailed information.
