8.1.4 Operator actions
Table 8.2
Typical operator actions
Operator action Notes
Acknowledge
Unacknowledged alarms must be acknowledged.
Acknowledging an alarm does not remove the alarm or active protection if the
Alarm condition
continues.
Silence
You can silence the alarm (horn/siren) output from the display unit.
Reset latches
Alarms can be configured with a
Latch
as an extra layer of protection.
Latched alarms require resetting after they have been acknowledged.
Shelve
Most alarms can be shelved for a selected period of time. During this period, the alarm protection is not active.
Once the period of time has expired, the
Alarm condition
is rechecked and may become active again if the
Alarm
condition
remains active.
Out of service
Most alarms can be removed from service. No period of time needs to be given.
The system does not automatically return the alarm to service, and this requires action to do so.
INFO
Some alarms can be inhibited from occurring depending on the designer's configuration of the system.
