4.e Generic messages activation contacts
The system has 8 unsupervised inputs for activating the generic and service messages recorded on uSD memory card Each message is activated
by closing its ground input, as shown in the figure below
The playback of the message is activated by a pulse Releasing the contact after shorting it to ground has no effect, 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 predefined priorities: message n has a priority over message n+1.
Example:
•When message 2 is played, the closing of contact 1 will stop message 2 and start message 1
•When message 2 is played, the closing of contact 2 will stop message 2
•When message 2 is played, the closing of contact 3 is ignored
This said, message 8 will has the lowest priority, but message 1 has the highest
Each contact is active only if an associated audio file is stored in the uSD card

4.f 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 foresees two resistors as described in the figure below configuration of these inputs is described in the
dedicated menu As a factory default, both inputs will trigger their respective message at the opening of the contact and the
playback will continue cyclically as long as the input is open Playback will stop at the closing of the contact
These inputs, that are typically activated by the fire alarm control panel are monitored against short circuit and cable cut: in this
case, the system will trigger a fault warning

Connect the resistors (supplied in the accessory bag) on each pair of contacts as shown in
the figure The resistors must be placed at the end of the cable, from the smoke and fire
signalling station side
Refer to the CONF ALARM INPUT MODE menu for the properties and configuration of the
input contacts
The inputs of the alarm messages are, by default, configured for normally closed contacts
Use cable with min section 0 5 mm, max 2 5 mm
If you do not intend to use the remote activation of messages, you cannot leave these terminals open without the device reporting a fault
Therefore, connect two resistors directly on the mainboard terminal so that the device does not signal a connection fault

5. MENU DESCRIPTION
6.1 Status Description
The system is designed to manage different operating conditions which, according to Standard EN54, are identified in four statuses The system
status is displayed by the LEDs on the front panel of the system and of the remote emergency microphone workstations
QUIET Status:
Operating condition “at rest”, without faults, no playback of voice alarms and no active “disablements ” Only the
diffusion of 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 front panel of 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 from the emergency
microphone workstation It can be activated via an external device connected to one of the supervised contacts, or
from 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 of the voice alarm in progress
FAULT Status (FAULT ARNING):
Operating condition indicating the presence of at least one fault detected by the internal diagnostic system The
status indication is accompanied by a fault 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 of detected faults and a brief description
DISABLEMENTS Status:
Operating condition in which the functions of one or more system sections are disabled
Even the faults related to the disabled section are suspended since safety functions are deactivated This condition
allows operating on the system without turning it off and without the fault condition (FAULT WARNIGS) being
activated
The display will show a POP-UP window indicating the number of active “disablements” and a brief description of
the section(s)
NOTE: Operating conditions may also occur simultaneously The LEDs corresponding to the active conditions will light up on the front panel and
the display will show a POP-UP window indicating which and how many events are active If the number of events exceeds the number of rows
of the POP-UP window, indications will cyclically scroll on the display In this case you can view entries using the UP and DOWN arrows

18
6.2 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 1, 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: 1, 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 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

LINE & AMPLIFIERS Menu
The Line & Amplifiers menu allows you to view and manage the status of amplifiers
and speaker lines They appear in the form of a list and can be scrolled using the UP
and DOWN arrows Each amplifier and speaker line is linked to the summary status:
Status of the amplifiers:
DISABLED  Disabled (Disablement)
ABSENT  Not installed
FAULT  Faulty
WARNING  Pre-alarm condition
OK  Running
Status of the lines:
DISABLED  Disabled (Disablement)
NOT IN USE  Not in use
NO CALIB  Impedance not calibrated
FAULT  Faulty
OK  Running
The system works with a Main amplifier and a possible Back p amplifier Both the
main amplifier and the backup amplifier, if installed, are monitored to ensure
effectiveness; in case of a faulty main amplifier, the backup amplifier automatically
takes over, if installed
For details of the status of the amplifiers you can select from the list and press OK to
access the Main amplifier detail / Back p amplifier detail screen that indicates the
status in detail In particular, the display shows the type of amplifier selected and its
operating status:
Func: Connected / Active  Connected to the load and active
Connected / Powerdown  Connected to the load and in energy saving
mode
Disconneted / Powerdown Disconnected from the load and in energy
saving mode
The system works with a single line of speakers that can be managed in single or
double mode, also called A&B mode The content diffused via speakers is unique in
both single-line and double-line mode, A&B line The difference between the two
modes is the possibility, in A&B mode, to manage a fault on the speaker line and
recover the lost sound pressure by transferring power on the line that is still operating
In the event of a fault, e g short-circuit, of the single-mode speaker line (not A&B), the
system isolates the line to avoid damaging the amplifier, making it impossible to
diffuse any contents On the contrary, if the line of speakers was wired in double
mode, alternating a line A speaker with a line B speaker and homogeneously
distributing the speakers on the surface to be sonorised; in the event of a fault on one
of the two lines, e g short-circuit, the system isolates the faulty line and increase the
volume of the remaining line so as to recover the lost sound pressure
