The sequence of events is:
At 10:44:42, a microphone fault occurred.
At 10:44:45, the microphone fault cleared
At 10:45:22, a user logged on with managerial privileges.
The following items are always noted in the event log:
Faults occurred
Faults cleared
Configuration changed
Manager or engineer logged in
Manager or engineer logged off
System initialised: this only occurs on unit power up
System reboot requested
Log cleared
As a result, an audit trail is shown on the status of the esystem, and any changes
made to the configuration.
Each menu option that adds an entry into the event log will be detailed in that
menu entry.
Set volume
This menu allows the user to change the volume settings for the microphone, and
sets the priority at which the microphone is to be used on the system.
Vol
changes the microphone volume between 0db to -31db. The volume can
also be muted.
Bass
changes the microphone bass level b16db to -16db.
Mid
changes the microphone mid level b16db to -16db.
Treb
changes the microphone treble level b16db to -16db.
Lvl
changes the priority of the microphone:
Page
level will override all non-emergency pages and messages, but any
emergency page or message will still play.
Emer
level will override all other audio except a dedicated fire microphone.
Note: if any key switch is defined as
Emergency
, this will override the
Lvl
setting here. Configuring key switches is an engineer function, and will be
described later.
Any changes to the volume settings are always stored in the event log.
Set date & time
This menu allows the user to change the date and time, not only on the ALP, but
on every unit on the network, thus synchronising the time.
