Backup Power (See Figure 3)
In the backup power system, all of the local power lines
are connected in parallel to one centrally located power
source of 24 Vdc.
Advantages of the Backup Power System:
•
The entire system may be independent of local line
voltage.
•
The entire system can be switched to an emergency
standby power source in the event of a power failure.
•
The central power system has the added advantage
that an auxiliary power supply, such as the Federal
Model PS600 can be used to power the local
Audio Router Device. If the PS600 is used, it is not
necessary to switch the power source if a power
failure occurs.
Disadvantages of Backup Power System:
•
A separate power source for all remote devices is
required. Heavy power lines are required from that
power source to the remote devices in the system.
The size of the power lines is dependent upon the
number of amplifiers and the total distance of the
power loop in order to minimize the voltage drop
while a signal is being routed.
•
Future expansion is limited by the current capacity
of the power source and the power lines that were
initially installed.
•
Central power installations must comply with local
electrical codes. Most power circuits are Class I
circuits. Therefore, conduit will probably be required.
Installation costs are higher than a local power
system.

System Power Connections.
SHOCK HAZARD: Installation with the system power on
could cause serious injury or death. Do not perform any
installation or maintenance on this system when power
is on. Ensure that the power is disconnected before
proceeding.
This device is to be installed by a trained electrician who
is thoroughly familiar with the national electrical code
(NFPA 70) and local codes and will follow the guidelines.
If this unit is to be connected to a non-power limited
24 Vdc supply, the National Electrical Code (NFPA70)
requires that those leads be separated from other
classes of wiring connected to this unit.
Cross-talk, interference, or hum can be induced in signal
lines, causing poor audio output or confusing messages,
which interferes with the capability of this equipment.
Do not install power lines in the same conduit as signal
lines.
Operating power is connected to AR2000-M by inserting
the plug end of the line cord into any standard 120 V,
60 Hz outlet. The AR2000-M is factory set for 120 Vac
50/60 Hz operation. If 240 V operation is preferred, the
input block provides a switch that must be set to this
position in order to function at 240 Vac operation.
To use 24 Vdc either as a primary or auxiliary source of
power, connect the "+" terminal of 24 Vdc power supply to
the "+" terminal at the 24 Vdc BACKUP POWER terminal
on the AR2000-M and "-" terminal of the 24 Vdc power
supply to the "-" terminal at the 24 Vdc BACKUP POWER
terminal on the AR2000-M located in the back of the
device. See Figure 3.
