Figure 3-3.
CAUTION
Improper installation could render this system
inoperable, interfering with the indicating nature
of this product. The installation must conform to
applicable local and/or National Electrical codes.
If an emergency power source is required, a backup
power system described below should be employed.
WARNING
If the AR2000-M is to be connected to a non-
power limited 24 volt dc supply, the National
Electrical Code (NFPA70) requires that those
leads be separated from other classes of wiring
connected to this unit.
B. Backup Power (See figure 3-3).
1. General.
In the backup power system all of the local power lines
are connected in parallel to one centrally located power
source of 24VDC.
2. Advantages of the Backup Power System.
a. The entire system may be independent of local line
voltage.
b. The entire system can be switched to an emergency
standby power source in the event of a power failure.
c. 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.
3. Disadvantages of Backup Power System.
a. 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.
b. Future expansion is limited by the current capacity
of the power source and the power lines that were
initially installed.
c. 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.
C. AR2000-M System Power Connections.
DANGER
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.
WARNING
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.
