Table 5: Attenuators override outputs
NOTE: The average consumption of the attenuator override signal is 10mA per unit.
(*): The output voltage could vary between 20 and 27V depending on the state of the battery.
(b) END OF LINE INPUTS
The equipment has 8 dual inputs for connecting
end-of-line devices. Each input has 3 terminals, one
common and two terminals for lines A and B,
associated with the same ampli fier channel (CH-x).
When the activation signal occurs at one of the inputs,
a loudspeaker line failure will be detected.
The connection is via 8-pin female euroblock
connector with 3 contact of 3.81 mm pitch (supplied
with the unit). The wire size range for each pole of this
connector is: 0.14
1.5 mm2 (30 14 AWG).

2.4.4 EXTERNAL SYSTEMS SLOT INTERFACE
The equipment has a slot where the ETX-1 module can be integrated. This module
allows connection to NEO-Extension units, the control, monitoring and con figuration through
the data network, the reception of audio sources from the data network and the integration with
third-party systems. The ETX-1 module is delivered as part of the equipment.
(a) SYSTEM CONNECTION PORT X
The X port allows the connection of an external Ethernet network that can be used for
control, monitoring and con figuration and the reception of audio over the data network. It is
possible to con figure this port to be disabled during emergency mode, therefore enhancing the
security in the internal network.
(b) SYSTEM CONNECTION PORTS A AND B
The equipment has two ports for the connection with other systems and NEO-
Extension units. The behavior of this ports can be con figured by a dip-switch as indicated in
section (e). The default mode will be position 01, where A will be the main Flexnet connection
and B the redundant Flexnet connection. In case of failure in port A, the system will
automatically switch to port B.
