table 3: IEC60849 - 4.3.1 Classification of priorities
Requirement Compliance Signature
It is necessary to decide upon an order of
priority for the message distribution based
upon:
Compliant, if properly installed. Responsibility of
the installer.
a Any automatic programmed response. Compliant, if properly installed. Responsibility of
the installer. The Voice Alarm System has a priority
structure.
b The perceived risk to occupants, which may
require manual override of the programmed
response.
Compliant, if properly installed. Responsibility of
the installer. EMG microphone always has priority
over automated messages.
Events shall be given a level of priority
according to their urgency. The following
primary levels are recommended but there may
be advantages in adding further subgroups,
depending on the operational strategies of the
site:
Compliant, if properly installed. Responsibility of
the installer.
a Evacuate - potentially life-threatening situation
needing immediate evacuation.
Compliant, if properly installed. Responsibility of
the installer.
b Alert - dangerous situation nearby requiring
warning of pending evacuation.
Compliant, if properly installed. Responsibility of
the installer.
c Non-emergency - operational messages, e.g.
system test, etc.
Compliant, if properly installed. Responsibility of
the installer.
The use of these levels in descending order of
priority will ensure that appropriate alarm
signals and messages are provided first to the
zones immediately at risk.
Compliant, if properly installed. Responsibility of
the installer.
