III. INSTALLATION.
SAFETY MESSAGE TO INSTALLERS
Peoples lives depend on proper installation of
our products. It is important to follow all instructions
shipped with these products. These devices are to be
installed by a qualified electrician in accordance with
the National Electrical Code (NFPA 70), or other
national or local codes, under the direction of the
local authority having jurisdiction.
The selection of the mounting location for the
device, its controls and routing of the wiring is to be
accomplished under the direction of the Facilities
Engineer and the Safety Engineer. In addition, listed
below are some other important safety instructions
and precautions you should follow:
• Read and understand all instructions before
installing or operating this equipment.
• Do not connect this unit to the system when
power is on.
• Speakers connected to this system can pro-
duce loud sounds which may cause, in certain
situations, permanent hearing loss. You
should take appropriate precautions such as
wearing hearing protection.
• After installation, test the Audio Router
sound system to ensure proper operation.
• Show these instructions to your Safety
Engineer and then file them in a safe place
and refer to them when maintaining and/or
reinstalling the unit.
• Establish a procedure to routinely check the
sound system for proper activation and
operation.
• Consult the authority having jurisdiction in
your area regarding the proper use and
installation of this product.
3-1. UNPACKING.
After unpacking the unit, examine it for damage
that may have occurred in transit. If equipment has
been damaged, do not attempt to install or operate it.
File a claim immediately with the carrier stating the
extent of the damage. Carefully check all envelopes,
shipping labels and tags before removing or destroy-
ing them.
3-2. MOUNTING ARRANGEMENTS.
The AR2000-M provides four (4) holes for
mounting in a standard rack. It utilizes a space of 2U.
The AR2000-P provides four (4) holes for mount-
ing in a standard rack. It utilizes a space of 1U.
The AR2000-Z provides four (4) holes for mount-
ing in a standard rack. It utilizes a space of 1U.
3-3. ELECTRICAL CONNECTIONS.
DANGER
To avoid electrical shock and damage to the
device, do not attempt to connect wires when
power is on.
Terminal blocks are supplied on the AR2000-M
for field wiring. Strip 1/2" of insulation from the
wiring leads. Attach the appropriate wires to the
corresponding terminals. Tighten the screws to
insure that the wires are firmly held in place. The
terminals will accept conductor sizes 23 AWG to 13
AWG.
3-4. SIGNAL LINES.
A. The signal lines transfer the tone signals
and verbal messages from the AR2000-M to the
selected zones and their devices. In order to reduce
the possibility of cross talk, hum and static noise
pick-up, the signal lines must be twisted pair,
shielded audio cable. Although the majority of sys-
tems use AWG 18 shielded twisted pair audio cables,
the size of the audio cable should be adjusted to
correspond to the level of audio being routed in your
application.
CAUTION
If too small a wire gauge is used, unaccept-
able 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 22AWG.
B. Federal does not recommend that new or
existing telephone lines be used as signal lines in an
Audio Router system for the following reasons:
1. Interference from other services or
systems, or interference from the system to other
services.
2. Cross talk, interference or hum induced
by other telephone lines.
3. Extended downtime because of the second
party involvement required to service the lines.
4. The additional cost of installation, inter-
facing devices and monthly charges as opposed to a
one-time cost of performing the installation.
