Internal and External Alarms
There are a number of internal alarms and four external alarm inputs.
The internal alarms have fixed alarm levels. They are listed on
page 11-14.
The external alarm inputs, EAL1 - EAL4, can be configured for various
alarm levels and alarm purposes in the Alarm Configuration window
(description on page 11-4). Some of the alarm input purposes are
described below.
EAL1
The EAL1 external alarm input can also be used for mains breakdown
alarm. This is further detailed in the Mains Breakdown Relay section in
Chapter 3.
EAL2
The EAL2 external alarm input can also be used for battery backup alarm.
EAL3
The EAL3 external alarm input can also be used for fiber optics alarm,
provided the Fiber Optic OMT software is used.
EAL4
The EAL4 external alarm input can also be used for an alarm which is
activated if the repeater door is open.
External alarm Ceasing
The external alarm inputs can be selected with or without Ceasing.
• With ceasing, e.g. Warning w ceasing, means that activated alarms as
well as ceased alarms are reported to the OMT32. The latter as
Ceasing.
• Without Ceasing, e.g. Warning w/o ceasing, means that an activated
alarm will be reported to the OMT32. When the cause of the alarm has
ceased, the event is assigned the None level.
