1. INTRODUCTION
The AE300 voice alarm system is a device for signalling in case of fire, designed according to EN Standards 54-16 and
54-4 It is an integrated, monolithic system with a single casing containing the voice alarm system blocks and the
power supply unit with backup batteries The system can play back recorded alarm messages through the monitored
contact inputs, or an operator can speak directly through a microphone integrated in the front panel, or from a
remote emergency microphone workstation
The system also has inputs for a service microphone workstation, background music diffusion, contacts for playing
back generic messages, as well as an Ethernet port
Depending on the model, the system has (or does not have) a backup amplifier
2. SAFETY NOTES AND ARNINGS
•This device must be installed in accordance with UNI Standard EN54-32:2015 and serviced only by qualified
personnel.
•This manual must be read and understood before commissioning the device.
•This device is set-up for operation using mains voltage within the 230 V +10% -15% range and 48V backup
batteries with 7.2A/h capacity.
•It is necessary to strictly follow the instructions in Par. 4.p “Connection to the mains power supply and
earthing”
•The device is protected by fuses on the main power supply (230V) and on the backup power supply (48V
battery). The fuses, respectively indicated as F1 and F2, are present on the power supply card. F1=T3.15AH,
F2=T8AH
•All connections must be made with device off.
•The end of a stranded conductor must not be terminated with a soft solder in the points in which the
conductor is subjected to a contact pressure (e.g. the header of the wirings which go to the cable seal
terminals must not be tin-plated but terminated with a crimping ferrule.)
•The installer is responsible for setting up a 6A-C6 circuit breaker (in appropriate electrical panel) dedicated
to this device. The circuit breaker must be placed in an easily accessible position. The circuit breaker must
bear the words “VOICE ALARM SYSTEM – DO NOT S ITCH-OFF”
•In order to avoid the risk of electric shocks, when accessing the inside of the device you must disconnect
the power supply network (230V). It is also necessary to disconnect the battery as there is a DANGEROUS
ENERGY LEVEL inside the machine (in particular to fastons J6 and J7).
•Do not expose the device to humidity or rain or any other liquid. Keep the device away from objects or
containers with liquid that could be accidentally poured inside, through the ventilation slots.
•Install the device in a cool, ventilated place and away from heat sources.
•Install the device so as not to obstruct the ventilation slots.
•Connect only batteries with the rated voltage and capacity described in this manual.
•Do not reverse the polarity of the batteries.
•The batteries must have a casing with flammability class HB or better
•hen installing the device, be very careful not to damage the electronic card with tools (pliers,
screwdrivers, etc...).

Front panel
The front panel of the machine has the user interface through which you can manage the system and view its status
At the top, the LEDs synthetically report the machine statuses:
•Green LED - PO ER: indicates that the machine is on and operating
•Red LED – VOICE ALARM: indicates that a voice alarm or evacuation message is being played back
•Yellow LED – FAULT ARNING: indicates that the machine, a loudspeaker line or a connection to the system is faulty
•Yellow LED – DISABLEMENT : indicates that the monitoring of one or more machine functions has been deactivated
In the central part, the display shows the details on the machine status and, through the keyboard, you can access the internal menus
Bottom-right of the user panel, the ALARM and WARNING buttons manually activate alarm or evacuation messages To activate these alarm
messages, or access the machine functions in the menus, you must login at access level 2 with the key (bottom-left) or by entering a password in
the appropriate menu
Finally, there is a PTT microphone on the machine front panel for issuing speakerphone alarm and evacuation messages To activate the
microphone, you must login at access level 2 (with key or password), then press the key on the side of the microphone to speak

4. INSTALLATION AND MAINTENANCE
The system must be installed by qualified personnel and in accordance with UNI Standard EN54-30
Unpack the device, loosen the two screws on the right of the front panel and rotate the door on the pins on the left side
Inside are the machine electronics composed of three or four cards, depending on the model (with or without backup amplifier)
4.a all mounting
Fix the device to the wall with wall plugs and screw through the holes on the bottom of the container, indicated in the figure below by arrows:
Use suitable type wall plugs according to the characteristics of the wall and with load from 0 30 to 0 65 kN The device must be fixed to the wall
by qualified personnel
4.b Connection of the speaker lines
The terminals for connection to the speaker lines are located top-right on the main board, just below the fairlead window Connect the
loudspeaker lines to 100V as shown in the figure The overall load applied to the two lines must not exceed 300W
When wiring the loudspeaker lines, be very careful not to short-circuit the two poles between them. If the loudspeaker lines are in short-
circuit, the system is not able to play back any alarm message, even if the fault is reported on the user interface.

The system has three status signal outputs These open collector outputs require a pull-up resistor that can be omitted if the pull-up is already
present inside the equipment to which these outputs are connected (e g smoke and fire signalling station)

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
