4.g Generic messages activation contacts
The system has 8 unsupervised inputs or activating the generic and service messages recorded on uSD memory card. Each message is activated
by closing its ground input, as shown in the igure below.
The playback o the message is activated by a pulse. Releasing the contact a ter shorting it to ground has no e ect, but the message will be
played till its end. When a message is being played, a second pulse will stop the player.
Generic messages have prede ined priorities: message n has a priority over message n+1.
Example:
•When message 2 is played, the closing o contact 1 will stop message 2 and start message 1
•When message 2 is played, the closing o contact 2 will stop message 2
•When message 2 is played, the closing o contact 3 is ignored.
This said, message 8 will has the lowest priority, but message 1 has the highest.
Each contact is active only i an associated audio ile is stored in the uSD card, re er to relative menù section. OK -> 3 x DOWN -> RECORDED

4. Alarm messages activation monitored contacts
The system has two monitored dry contact inputs to trigger the EVACUATE and ALARM (alert) messages that are stored in the uSD
card. The connection oresees two resistors 2.2Kohm, connection example described in the igure below. (Alarm Input // Evacuate
Input).
As a actory de ault, both inputs will trigger their respective message at the opening o the contact (NC) and the playback will
continue cyclically as long as the input is open. Playback will stop at the closing o the contact.
These inputs, that are typically activated by the ire alarm control panel are monitored against short circuit and cable cut: in this
case, the system will trigger a ault warning.

MENU DESCRIPTION
5.1 Status Description
The system is designed to manage di erent operating conditions which, according to Standard EN54, are identi ied in ive status. The system
status is displayed by the LEDs on the ront panel o the system and o the remote emergency microphone workstations.
QUIET Status:
Operating condition “at rest”, without aults, no playback o voice alarms and no active “disablements.” Only the
di usion o background music or generic messages (not alarm ones) is allowed. When the system is in the quiet
status only the green LED is lit on the ront panel o the unit, to indicate that the system is powered.
ALARM Status (VOICE ALARM):
Operating condition where a pre-recorded or speakerphone voice alarm is being issued rom the emergency
microphone workstation. It can be activated via an external device connected to one o the supervised contacts, or
rom an emergency microphone workstation. While a voice alarm is issued, the system turns on the red LED to
indicate the voice alarm status. The green LED remains on to indicate that the system is powered.
The display will show a POP-UP window indicating the source o the voice alarm in progress.
FAULT Status (FAULT WARNING):
Operating condition indicating the presence o at least one ault detected by the internal diagnostic system. The
status indication is accompanied by a ault intermittent acoustic signal (buzzer) and the yellow LED lighting up on
the unit panel. The green LED remains on to indicate that the system is powered.
The display will show a POP-UP window indicating the number o detected aults and a brie description.
DISABLEMENTS Status:
Operating condition in which the unctions o one or more system sections are disabled.
Even the aults related to the disabled section are suspended since sa ety unctions are deactivated. This condition
allows operating on the system without turning it o and without the ault condition (FAULT WARNIGS) being
activated.
The display will show a POP-UP window indicating the number o active “disablements” and a brie description o
the section(s).
SYSTEM FAULT Status
Indicates the attempt by the machine to re-initialize ollowing a block in the execution o the so tware.
Two cases are distinguished:
1) I the machine restarts correctly, normal operation is resumed (but the System Fault LED remains on); try
i the machine responds correctly to the commands.
2) A serious ault has occurred, the machine has not re-initialized and does not respond to commands.
In both cases, switch o the machine completely (disconnect the mains plug and the battery socket), then repeat
the power on procedure.
NOTE: Operating conditions may also occur simultaneously. The LEDs corresponding to the active conditions will light up on the ront panel and
the display will show a POP-UP window indicating which and how many events are active. I the number o events exceeds the number o rows
o the POP-UP window, it is necessary to collapse the visualization, the messages are gathered on type and can
be read using the arrows on the ront panel. The messages groups are: “Voice Alarm “_ active voice alarm
messages, “Fault warnings“ current aults “ Disablements “ the di erent sections are o . On the POP-UP
windows the number o the events or each category are displayed.

17
5.2 Main Screen
In the absence o warnings, the main screen shows the ollowing in ormation:
•System time: shows the current system time; or the system events to be properly recorded, this should
be always updated. It is also important to veri y 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 o a ault, a POP-UP window will appear indicating the number o active aults, the presence and
number o “disablements” and i an alarm message is in progress.
Icons
Current access level: a key positioned bottom-le t o 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 o rules in the number o repetitions o the current
message. The rules impose a minimum number o reproductions and/or a maximum number o reproduction
cycles.
Fault o one o the two lines A or B o a single zone with volume increase. In case o line ault with redundant
A&B line, an icon will appear to indicate that the “non- aulty” 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 o a pre-recorded or voice message you can activate the “MUTE” unction by pressing the
appropriate button on the ront 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 o a pre-recorded message, the output is
muted only at the end o the message itsel to avoid compromising its intelligibility. Likewise, when mute is
removed, the message will be played back at the end o the reproduction cycle. Mute activation while an
emergency microphone is “speaking” is immediately e ective.
Warning on In case o a system event, a lashing 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.

in which the commands to insert or remove the "disablement" condition o the section are available.
From the POP-UP, with the section in "disablement" it is possible to per orm the calibration o the line
impedance by selecting the "Calibrate line" or "Line autoset" command.
The "Calibrate line" command measures the line impedance o active con igured speakers.
The "Line autoset" command measures the impedance o all lines and activates those in which it detects a
load, the others will be disabled.
The execution takes about 40 seconds and the result is reported in the detailed status screens o the
speaker and ampli ier lines.
At the end o the calibration it is necessary to remove the disablement.
NOTE: When the "Line & Amp" section is in "disablement" all the sa ety unctions related to the
ampli iers and speaker lines are deactivated. Any "FAULTS" errors are also removed. The "disablement"
unction allows you to operate on the speaker lines without interrupting system operation and without
generating "FAULTS" errors.
