HANDLING ABNORMAL CONDITIONS
When an abnormal condition occurs, at least one of the interface panel LEDs (SYSTEM ALARM, SUPERVISORY
SERVICE, or SYSTEM TROUBLE) begins to flash, and the tone-alert sounds. The alphanumeric display on the
interface panel shows the total number of abnormal conditions present in the system. At a glance, you know how
serious the situation is by reading the number of abnormal conditions displayed, such as the single alarm condition
shown below.
The system also creates a “List” when abnormal conditions exist. The list contains the number of abnormal
conditions present in the system. The acknowledge keys are pushed to view the abnormal condition list, and review
each condition, if required.
When an Alarm Condition is detected by the system, the SYSTEM ALARM LED flashes and the tone-alert begins
pulsing. For supervisory service and trouble conditions, the appropriate interface panel LED flashes, and the tone-
alert sounds and remains ON without pulsing.

appropriate list. Note that the acknowledge function may be passcode protected. If you have insufficient privilege to
acknowledge the condition, a message will indicate the problem, and will allow you to view the points without
acknowledging them. If you have sufficient privilege to acknowledge the condition, a message is displayed informing
you that the condition has been acknowledged. (See Operator Access Levels, Section 9, and Log In Procedure,
Section 1, for details.)
The 4100 system can be configured with either Global or Individual Acknowledge. When Global Acknowledge is

Note that the acknowledge function imposes a delay of at least one second between point acknowledgments. This
minimum delay allows you to view the information displayed on the alphanumeric display for each point that is being
