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.

The 'A4Station should be e5uipped with a soundboard and spea&ers if

sound files will be played. The soundboard driver should support !A"formatted files. The annunciator configuration should be built and

saved on the station e5uipped for sound.

The 'S (egistry must be updated to allow the Annunciator Tas& to

run 6See the picture below7. The 80nable Annunciator Tas&9 fieldunder 8'achine Settings9 must be changed to :es. This field is read by

the Annunciator Tas& during startup. (estart the station if necessary. If

the value is 8:es9* the tas& will continue. If the value is 8No9* the tas&

will exit.

There is no auto failover of alarm annunciation from one maxSTATION

to another* so a system should have two maxSTATIONs set up to

perform alarm annunciation.

The alarm silence function as installed from the release is not global. 2owever*

global silence is supported provided a registry update is made to eachmaxSTATION. ,erform this update as follows +og on to the station at the

station* no entry is necessary. An open and close brac&et with no text in between

indicates that the current station processes the silence re5uest. If the annunciator tas&

is running on more than one station* enter the omputer Names in the Annunciator

Silence Station ; and Station < fields. o not delete the brac&ets from any of the

annunciator silence station fields.

After entering the desired omputer Names* clic& O= to save the changes and
