5.2 Main Screen
In the absence of warnings, the main screen shows the following information:
•
System time: shows the current system time; for the system events to be properly recorded, this should
be always updated. It is also important to verify that seconds are regularly counted, otherwise the system
CPU may be locked.
•
Current access level: A key indicates the current access level, 2 or 3.
•
System status: The “System OK” text indicates that the system is operating.
In case of a fault, a POP-UP window will appear indicating the number of active faults, the presence and
number of “disablements” and if an alarm message is in progress.
Icons
Current access level: a key positioned bottom-left of the display indicates the current access level, 2 or 3.
Message playback with active repeat rules. In case alarm or evacuation messages are played back, an icon with
two alternate arrows may appear to indicate the presence of rules in the number of repetitions of the current
message. The rules impose a minimum number of reproductions and/or a maximum number of reproduction
cycles.
Fault of one of the two lines A or B of a single zone with volume increase. In case of line fault with redundant
A&B line, an icon will appear to indicate that the “non-faulty” line is working with an indicated volume
increase.
Mute on. With mute on, an icon with the loudspeaker crossed is displayed to indicate that the mute is active.
During the playback of a pre-recorded or voice message you can activate the “MUTE” function by pressing the
appropriate button on the front panel; when on, an icon with a crossed loudspeaker appears on the display.
To deactivate, simply press the appropriate button again and mute will be removed.
NOTE: as per EN54-16, when “Mute” is activated during the playback of a pre-recorded message, the output is
muted only at the end of the message itself to avoid compromising its intelligibility. Likewise, when mute is
removed, the message will be played back at the end of the reproduction cycle. Mute activation while an
emergency microphone is “speaking” is immediately effective.
Warning on In case of a system event, a flashing triangle appears to attract the user’s attention. The warning is
removed when you access the “System Logs” system event menu, which lists the system events.
