When the button looks like this…
…you will hear audible annunciation of
Urgent priority alarms only.
Suppression button states(continued...)
If your system is configured to suppress both low and high priority alarms, each time you
click the button, it will cycle through each of the three states.
If your system is configured to suppress only low priority alarms, each time you click the
button, it will cycle between only the first two states.
If your security level does not permit you to suppress audible annunciations, the button is
dimmed.
Functionality
When the suppression of audible annunciations is enabled, and you have the appropriate
security level, you can suppress Low and/or High priority alarms, depending on how your
system is configured. Keep in mind the following considerations:
n
When you press the
Suppress audible annunciations
button, all alarms that are
currently annunciated are silenced. This includes any existing urgent alarms. However,
any new urgent alarms that occur will be annunciated.
n
Suppression of the audible annunciation will last for the duration predefined for your
system.
n
Ten seconds prior to the suppression period ending, the suppression buttons begin to
flash to alert you that the suppression period is about to end.
n
At any time during the suppression period, you can click the suppression buttons to
restart the duration period.
n
Each time audible annunciation is suppressed, a log entry is added to the Event
Summary. Events record the start of a new audible suppression, and again when the
current audible suppression period ends.
n
When the suppression period ends, the audible annunciation of alarms that were
suppressed during the suppression period will continue to remain suppressed. Re-
annunciated alarms will also continue to remain suppressed. Only new alarms will
sound.
n
If at any time during the suppression period either Station closes and reopens, or an
operator logs off and then logs in, audible annunciation suppression is not affected and
will continue to run.
