WARNING
If this unit 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.
CAUTION
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 merely inserting the plug end of the line cord into any
standard 120 volt, 60 Hz outlet. The AR2000-M is factory
set for 120VAC 50/60Hz operation. If 240 volt operation
is preferred, the input block provides a switch that must
be set to this position in order to function at 240VAC
operation.
If it is desired to use 24 VDC either as a primary
or auxiliary source of power, connect the "+" terminal of
24 volt DC power supply to the "+" terminal at the 24VDC
BACKUP POWER terminal on the AR2000-M and "-"
terminal of the 24 VDC power supply to the "-" terminal at
the 24VDC BACKUP POWER terminal on the AR2000-M
located in the back of the device. (See figure 3-3.)
D. AR2000-P and AR2000-Z Power
Connections.
Operating power is connected to AR2000-P
and AR2000-Z by merely connecting 24 VDC from the
AR2000-M to each unit. A terminal block is provided
at the rear-left side of each unit for power connection.
Observe and maintain proper polarity when wiring the
power to these units. Connect the "+" terminal of the
AR2000-M to the "+" terminal of the AR2000-P at the
"+" terminal located in the back of device. Connect the
"-" terminal of the AR2000-M to the "-" terminal of the
AR2000-P at the "-" terminal located in the back of
device. An additional 24VDC power outlet is provided on
each AR2000-P and AR2000-Z for daisy-chaining the
power to each sub-unit. Repeat for each AR2000-P and
AR2000-Z.
Setup for the AR2000-P presets is done in the
same way as the AR2000-M presets.
Setup for the AR2000-Z zones is done in the
same way as the AR2000-M. An audio input is provided
on each unit to be routed to each of the zones it selects.
This audio should be connected by wiring a connection
from the master audio output to the provided input
terminals. (See figure 3-5.) Each additional AR2000-Z
should obtain audio in the same manner from the unit
above. (See figure 3-5.)
(See figure 3-4.)

3-8. CONNECTIONS TO REMOTE SWITCHES.
The AR2000-M presets can be activated remotely
by any normally open low current switch contacts
having a current capacity of at least 50 mA inductive.
Figure 3-6 illustrates the connection of switch contacts
to the AR2000-M. S1, S2, S3 and S4 represents remote
switch contacts such as those found in flow switches,
program clocks, heat detectors, and smoke detectors.
The remotely activated presets function as long as the
activating contacts remain closed. A jumper needs to be
placed across OPTO COMMON and the provided +24V
terminal next to it on the back of the AR2000-M in order
for the remotely activated presets to function. A remote
switch may be connected to the ALL CALL position if
desired. These are all Normally Open contacts that initiate
with contact closure and remain active until the contact is
opened again.
3-9. INPUT SOURCE CONNECTIONS.
WARNING
Installation or maintenance on AR2000-M when
power is on can result in serious injury or death.
Do not perform any installation or maintenance to
the system when power is on.
Set selector for CH A to the appropriate input
voltage, 1Vrms, 25Vrms or 70Vrms. Connect the "+"
of the source device to the "+" terminal at the Channel
A input. Connect the "-" of the source device to the "-"
terminal at the Channel A input. Repeat this process for
the Channel B input. CH A and CH B volume controls are
available just above each input selector to allow the input
gain to be adjusted.
CAUTION
Be certain to set the input selector switch to the
appropriate input voltage to avoid damage to the
unit and the device being connected.
3-10.
COMMUNICATION CONNECTIONS for
AR2000-P and AR2000-Z.
WARNING
It is important that the communication lines
be properly connected to their respective
communication port. Failure to connect the
cables properly will damage the devices and
possibly render them inoperable.
The label on the back of each device indicates
where the communication cable link should be
connected. See figure 3-6 for appropriate placement.
