Figure 4-20. Typical Trouble Message Display
The following actions also occur when any trouble condition is reported:
• The Trouble LED on the display flashes
• The internal buzzer pulses
• The Trouble Relay de-energizes to transfer the Trouble contacts
• The trouble event is stored in the event log
• The trouble message is transmitted to peripheral devices (such as Remote Display Control
Modules and Remote LED Annunciator Modules), if applicable
• The trouble message is communicated via the RS-232 ports.
• Point- or group-specific and general trouble outputs activate, including previously silenced
outputs.
4-10.2.1 WHAT TO DO WHEN A TROUBLE OCCURS
Press the <SYSTEM ACKNOWLEDGE> Key to change the Trouble LED from flashing to steady and
to silence the internal buzzer.
It will be necessary to press the <SYSTEM ACKNOWLEDGE> Key once for each trouble report if
multiple unacknowledged trouble events are present and the global acknowledgment option has not
been selected.
Note: Global Acknowledge for acknowledgement of multiple events is not ANSI/UL 864 compliant.
Each acknowledged trouble event (or block of events when the global acknowledgment option
is used) will disappear from the display. The display changes to indicate the next
unacknowledged trouble event in the case of multiple trouble events. The active troubles can
be manually displayed in order of occurrence using the <SCROLL> Key at this time, after all
trouble events have been acknowledged. A summary of the number of active trouble events will
be displayed as shown in Figure 4-21 at the conclusion of each manual scroll cycle.
Figure 4-21. Typical Message After Manual Trouble Scroll Cycle
A trouble event that occurs after all previous trouble events are acknowledged will re-initialize the
Trouble State as defined in Section 4-10.2.
