Overview -
Acknowledging an
Alarm
The first step in managing an alarm condition is to acknowledge the alarm. Acknowledging an
alarm does two important things:
• It records the time and date at which you observed the presence of an alarm, trouble, or
supervisory condition on the operator interface panel, and stores that information in the
system's historical log.
• When you press the acknowledge key, the system displays specific data on the location of the
alarm.
The FACP can be configured with either global or individual acknowledge. These options function
as follows:
• Global acknowledge . When global acknowledge is enabled, one press of the
ALARM ACK key acknowledges every abnormal point currently reporting an alarm status.
This is helpful when a series of devices enter an alarm state (for example, all of the smoke
detectors in an area of the building), and you want to acknowledge all of them at the same
time.
• Individual acknowledge . If individual acknowledge is enabled, the ALARM ACK key
must be pressed to individually acknowledge each alarm. Individual acknowledge must be
selected if the panel is providing proprietary receiving service in accordance with NFPA 72.
The ALARM ACK key, which is used to acknowledge alarms (either globally or individually), is
located just beneath the SYSTEM ALARM LED
