The following actions also occur when any supervisory condition is reported:
•
The Supervisory LED flashes
•
The internal buzzer pulses
•
The supervisory event is stored in the event log
•
The supervisory message is transmitted to peripheral devices such as
RDCMs and ATM-Ls, if applicable
•
The supervisory message is communicated via the RS-232 ports
•
Point- or group-specific and general supervisory outputs will activate,
including previously-silenced outputs.
What to Do When a Supervisory Event Occurs
Press the <ACKNOWLEDGE> Key to change the Supervisory LED from
flashing to steady and to silence the internal buzzer.
It will be necessary to press the <ACKNOWLEDGE> Key once for each
supervisory event if multiple unacknowledged supervisory events are
present and the multiple-supervisory-event-acknowledgment option
has not been selected. See Paragraph 3-2.5.2.4.37 to enable the
multiple-supervisory-event-acknowledgment option.
Each acknowledged supervisory event (or block of supervisory events
when multiple event acknowledgment is used) will disappear from the
display after acknowledgment. The display changes to indicate the next
unacknowledged supervisory event in the case of multiple supervisory
events. The active supervisory events can be manually displayed in order
of occurrence using the <SCROLL> Key at this time after all supervisory
events have been acknowledged. A summary of the number of active
supervisory events will be displayed as shown in Figure 3-22 at the
conclusion of each manual scroll cycle.
Figure 3-22. Message After Supervisory Manual Scroll Cycle
A supervisory event that occurs after all previous supervisory events have
been acknowledged will re-initialize the Supervisory State as defined in
Paragraph 3-2.5.6.
How To Reset the Control Unit After a Supervisory Condition
Supervisory conditions are user configurable to be non-latching or
latching. There is no indication that a supervisory event has cleared when
multiple, acknowledged supervisory events are present regardless of
whether the supervisory event is configured for latching or non-latching
operation. The only indication will be that the supervisory event as
depicted in Figure 3-21 has disappeared from the set of manually scrolled
events and that the total number of supervisory events displayed in
Figure 3-22 has decreased.
The system will automatically return to the Normal Mode when all of the
supervisory events have cleared if the monitor modules that reported the
events were configured to be non-latching, or if all isolated SLC and IIM
devices and control-unit-based circuits are restored to normal-operating
condition.
Press the <RESET> switch to resume normal operations after a latching
supervisory event has cleared.
