Federal Signal AR2000-M Manuel D'utilisation page 4

REDUCED SOUND OUTPUT: If too small a wire gauge is
used, unacceptable signal voltage drop in the signal line
will cause reduced sound output from the remote signal
device. Only use a cable having wire gauge greater than
22 AWG.
Federal does not recommend that new or existing
telephone lines be used as signal lines in an Audio
Router system for the following reasons:
• Interference from other services or systems, or
interference from the system to other services.
• Cross-talk, interference, or hum induced by other
telephone lines.
• Extended downtime because of the second party
involvement required to service the lines.
• The additional cost of installation, interfacing
devices, and monthly charges as opposed to a one-
time cost of performing the installation.
Signaling Connections
CROSS-TALK: Cross-talk can occur between signal lines
and power lines, causing confusing messages, which
interfere with the capability of this equipment.
Do not install signal lines in the same conduit with power
lines. Avoid routing signal lines on cable trays with high
voltage power lines.
To connect the signal lines of the system to the
AR2000-M, connect a color-coded shielded twisted pair

of audio cables having conductors no smaller than 18
AWG to + and - of each zone output being utilized to
the appropriate remote device(s). See Figure 1. Every
remote signaling device in the system will be connected
in parallel to these lines. When connecting the remote
devices in parallel to the signal lines, observe the correct
polarity and install wire nuts over the connections.
NOTE: If using the supplied amplifier or an external
amplifier, the output audio must be connected using
appropriate wire from AUDIO OUT to AUDIO IN FROM
EXTERNAL AMP. If using the on-board amplifier, directly
connect the AUDIO IN FROM EXTERNAL AMP to the
AUDIO OUT terminals on the back of the AR2000-M. See
the Signal Lines section for recommended wire sizes.
Connection to Remote Devices
Physically install the remote device(s); follow the
installation instructions packed with the device.
A. 300GC, 300GCX, 300X, 302GC, 302GCX, 302X, 50GC,
and 50GCB
To connect these models to a 25 V
a Model AM25CK or AM70CK connector card must be
used. See Figure 1 and the instructions in the Signaling
Connections section. for the appropriate signal line
voltage.

The AR2000-M has a provision for connecting 70 V
operated speakers to its output. Connect the 70 V
at the terminals of Zone 1 – Zone 8 terminal block(s).
Connect the speakers in parallel to this line using 70 V
line tap. This output is selected by setting the switch on
the back of the AR2000-M to the 70 V
