The ACSI input integrates audio, communications and power allowing the emergency
devices to be fed directly from the integrated backup source.
The connection is made using standard UTP network cable T568B. The connection is
made by bus, with a maximum connection length of 1000m.
This input has a signal indicator LED for audio tests and a state LED that will indicate
that there are connected devices.
2.2.7 LINK output
This connector is intended for the future interconnection of ONE devices.
2.2.8 Pre amplified audio outputs. PRE-AMP OUTPUTS
ONE has 4 outputs at 1 Vrms (line
level) to connect external equipment as
backing amplifiers.
These outputs can be configured to
obtain the same audio as the zones or
as recording output of the messages of
microphones in evacuation.
Connection is made by 3-contact
Euroblock type connectors and 3,81
mm pass (given with the equipment).
Cable section range for each pole of
this connector is: 0,14 1,5mm2 (30
→
→
14 AWG). The maximum output load is
10Kohm.
2.2.9 Attenuator cancellation output, OVERRIDE
In the control board there are 6
attenuator override outputs for public
address lines. In idle state they have a
voltage of 0V. In active state, each
output has a voltage of 24V DC and
20mA of maximum current. Each exit
has two poles.
Connection is made using 2-contact
Euroblock female connectors and 3,81
mm pass (given with the equipment).
Cable section range for each pole of
this connector is: 0,14 1,5mm2 (30
→
14 AWG).

2.2.10 Internal connections
There are some connection ports for internal wiring. Some of them must not be
menipulated by the user.
a) Micro-SD card connector
This connection is used for software amplification as the installation of the EN54-4
battery charger.
