Alarm Annunciator
Alarm Annunciation in the maxSTATION provides an audible signal that an alarm
has occurred within a pre-defined hierarchical group. Some features of the
annunciation subsystem are listed below
The audible signal is selectable from a library of !A" files.
The !A" files can be set to single play or loop mode.
The !A" file is played when an alarm occurs in a hierarchical group that has
been assigned to an annunciator. #p to $% groups can be assigned to one
annunciator.
An annunciator supports a range of alarm severity and has an assigned priority.The !A" file of a lower priority annunciator is pre-empted by the !A" file of a
higher priority annunciator.
The alarm annunciator can also drive a digital output.
A tas& is included that allows annunciator configuration. The configuration is
saved in a 'icrosoft Access database file.
The annunciator configuration can be changed online.
A Silence button is included on the "ertical template of (untime. This button
turns off the currently playing sound and)or the digital output point. Note that
the alarm ac&nowledge buttons on the Alarm Summary* Alarm +ist* and ,oint
ac&nowledge button also perform the annunciator silence function.

Functionality
The Alarm Annunciation subsystem consists of two programs. The'S Annunciation Setup Tas& is used to define annunciators and
transmit this data to the Annunciator Tas&. The Annunciator Tas&
monitors alarm activity in each max,#/0)1 and will play the
configured sound if an alarm occurs in a group assigned to an
annunciator.
2ierarchical 3roups are defined in the max,#TOO+S onfigurator.
3roups are assigned to individual points in the max,#TOO+S
onfigurator.
3roup definition must be performed in the customer
database and the group names must be assigned to the desired points.
This database is then installed in each max,#/0)1 for annunciators tobe operational. See the max,#TOO+S onfigurator instructions for
information on group definition.
