CONFIGURATION OF INITIAL START-UP
The DBE108E must be plugged into a network where an Ethernet Switch with DHCP Server function is
present and active. The DBE108E is designed to work with both AE300 and / or AE604 for a total of 8 Evac
units.
To facilitate the identification, before networking the EVAC units, it is advisable to assign a unique name to
each of them from the unit’s Ethernet menu. In this guide, the following names have been assigned for the
three Evac units used as an example: AE604-1, AE300-1 and AE604-2.
For the first configuration proceed as follows:
•Make sure you have turned off all Evac units, bases and switches connected to the network.
•Turn on the DHCP Switch Server and any other switches on the network.
•Connect the AE300 / AE604 Evac units to the ethernet network.
•Switch on the AE300 / AE604 Evac units.
•Finally connect the DBE108E bases leaving the power supply disconnected.
•Turn on each DBE108E base by connecting the power cable while time holding down the “EVAC
MESSAGE” button: the bases start in configuration mode and automatically acquire the Evac units
connected to the network.
If you want to give a particular order of the Evac units that appear in the “STATUS” window (see point 5 of
the previous chapter), you must have the Evac units acquired one at a time in the desired sequence.
To do that, first turn on all the DBE108E present in the network in configuration mode (supplying the external
power supply while holding down the "EVAC MESSAGE" button) and then the Evac units in the desired order.
Wait for the single Evac unit to be displayed in the “STATUS” window before turning on the next one.
In the example shown in the figure, 3 Evac units have been connected in sequence: Evac unit n ° 1 AE604-1,
Evac unit n ° 2 AE300-1, Evac unit n ° 3 AE604-2.

12
•From the “STATUS” window, press “AUTO BUTTON”.
With this operation, the base is automatically programmed in a standard way, associating an EVAC unit to
each row of the display following the acquisition order of the various units. 4 buttons are displayed in each
row if the Evac is an AE604, while only one button is displayed if the Evac is an AE300.
The name of the EVAC AE604 / AE300 is shown inside each display button, followed by the number of the
assigned output line and with the name of the zone underneath. Repeat the “AUTO BUTTON” procedure on
other DBE108Es if present.
In the example, 4 buttons are assigned to the AE604-1 for zones 1..4, 1 button for the AE300-1 and 4 other
buttons to the AE604-2.
NOTE
Once the DBE108E bases have been programmed, by disconnecting or reconnecting the bases or the
various Evac units, the acquisition order of the Evac units remains unchanged.
MANUAL CONFIGURATION OF THE BUTTONS
Pressing the "CONFIG" label will open the corresponding page.
By pressing the triangle on the first drop-down menu at the top left, it is possible to select the EVAC unit
whose buttons you want to configure.

13
The name of the EVAC system is that one set on the Evac unit from the “Ethernet menu”: for details, see the
Evac unit manual.
Once the control unit has been selected, open the flag menu that identifies the buttons associated with the
Evac unit. In this example, since the unit is an AE604, 4 buttons will be editable: “BUTTON1”, “BUTTON2”,
“BUTTON3” and “BUTTON4”. If the selected control unit is an AE300, only “BUTTON1” is editable.
Once the button to be programmed has been selected, you can enable it by clicking on the “ENABLE”. If you
decide not to enable it, the button will not be displayed on the call windows, leaving an empty position.
In the automatic self-configuration procedure ("AUTO BUTTON" function), the "BUTTON1" is assigned the
speaker output (A + B) n ° 1 LINEOUT1 (ALL LINES in case of AE300), the name ZONE1 (ZONE in case of
AE300) and ENABLE active, thus to the following buttons:
“BUTTON2” respectively “LINEOUT2”, “ZONE2”, “ENABLED”
“BUTTON3” respectively “LINEOUT3”, “ZONE3”, “ENABLED”
“BUTTON4” respectively “LINEOUT4”, “ZONE4”, “ENABLED”
In this window it is also possible to change the name previously assigned by the autoconfiguration
procedure: by pressing on the name (in this case ZONE1), the cursor starts flashing and the new name can be
entered using the alphanumeric keypad (maximum 8 characters).
In the case of AE604, through the “LINEOUT” pull-down menu it is possible to assign any of the speaker
outputs (A + B) of the Evac unit or all of them (ALL LINES) to the selected button. To do this, open the drop-
down menu of physical outputs and select the desired output or assign them all using the ALL LINES setting.

14
To make the settings effective, before selecting another Evac unit or configuring another button from the
drop-down menu, press the "STORE" button.
CONFIGURATION OF A GROUP
The microphone console has 8 call GROUPS which can be called up directly from the buttons on the panel.
By pressing the GROUP "n" button, all the zone buttons previously associated with that group will be
automatically selected: at this point you can proceed with the desired call or message operation.
To associate a zone button to a group, after selecting the "BUTTON", proceed by selecting the desired group
from the "GROUP" menu.
After assigning the button to the group, press the "STORE" button to store the setting.
If it is necessary to cancel only the programming of the Groups without reprogramming the entire base, use
the "CLEAR GROUP" button in the "STATUS" window.
IMPORTANT: the “CLEAR GROUP” function deletes all groups!

15
USE OF THE MICROPHONE STATION
Once the configuration is complete, the base must be turned off and on again using the power connector
without pressing any button. In this way, the base will work in standard mode for the end user.
