CHAPTER 1
Introduction
Description
The PS-2001L and SPS-2001 are versatile power supplies that can be used in a
variety of Audiocom® intercom system applications. They both directly accept
any AC input power from 100 to 240 VAC, 50/60 Hz and can be configured to
power two separate intercom channels or one large intercom channel with twice
the intercom station capacity. Additionally, the units can be configured for
compatibility with Clear-Com® Intercom Systems. The units may be rack mounted
or used on a desktop.
For rack mounting, optional hardware is required. For desktop use, four non-
marring rubber feet are supplied. The SPS-2001 also provides a speaker with
two mixed inputs making it ideal for situations calling for a master station
with a microphone/speaker combination.
FIGURE 1. PS-2001L Front and Rear Panel Features
-
Combine/Isolate Switch: When in the Combine position, the unit will combine the audio signals of the two channels to create a single audio channel where all users can intercommunicate. When in the Isolate position, the unit will create two groups of completely independent users.
-
Channel Status Indicators: The indicators are green for normal operation and red when there is an overload or short circuit.
The circuitry in the unit will automatically reset when the overload or short circuit is located and fixed. -
Universal AC Power Input: The unit accepts any input power in the range of 100-240 VAC, 50/60 Hz.
-
Intercom Channel Connectors: When the Combine/Isolate switch is set to the Isolate position, each channel connector is powered separately and has completely separate intercom audio. When the Combine/Isolate switch is set to the Combine position, each channel is still powered separately, but the audio signals are combined so that all users on both channels can intercommunicate.
-
BAL/UNBAL Selector Switch: This selector switch allows the user to configure the unit for use in either an Audicom® (BALANCED) or Clear-Com (UNBALANCED) system. Compatibility includes channel connector pin-outs, channel power requirements, and call signaling requirements. The default setting for this switch is in the Audiocom® (BAL) position.
FIGURE 2. SPS-2001 Front and Rear Panel Features
-
Speaker, Inputs, and Volume Control: Two audio inputs are provided. The inputs are combined internally and set as a monaural signal to the internal speaker amplifier. The Volume control adjusts the level to the front panel speaker. Typically, these inputs are used with the speaker outputs of a master station when the master station is set for use with a panel microphone and speaker instead of a headset.

When the Combine/Isolate switch is set to the combine position, each channel is still powered separately, but the audio signals are combined so that all users on both channels can intercommunicate.
-
BAL/UNBAL Selector Switch: This selector switch allows the user to configure the unit for use in either an Audiocom® (BALANCED) or Clear-Com (UNBALANCED) system. Compatibility includes channel connector pin-outs, channel power requirements, and call signaling requirements. The default setting for this switch is in the Audiocom® (BAL) position.
CHAPTER 2
Installation
Configuration Switches
The BAL/UNBAL switch (located on the rear of the unit) is set to the Balanced (Audiocom) position when the unit is shipped from the factory. To set the switch to the Unbalanced (Clear-Com) mode, use a pointed object such as a pen to push in the switch.
The Combine/Isolate switch (located on the front of the unit) can be changed at any time by using a pointed object such as pen to push in the switch. When the switch is in the Combine position, all users on both channels may intercommunicate. When the switch is set to the Isolate position, channels 1 and 2 cannot intercommunicate.

Channel Capacity:
When connecting intercom stations to the PS-2001L or SPS-2001, determine the
total current for all stations on each channel.
The total per channel should no exceed 2A. If you exceed this limit, an
overload indication will be provided and the output of the power supply will
be turned OFF. Once the overload is corrected, the overload indications will
disappear and the power supply output will be turned ON. Note, if you are
using DC wallpacks with some intercom stations, you do not need to add the
current consumption of those station to the total current.
Audiocom Connections:
Intercom cable wiring details are shown in figure X. Speaker and
interconnection cables (SPS-2001 Only) are standard RCA phono types. For
program input cable wiring, refer to your master intercom station user manual.
Some typical applications are shown in the figures on page 9.
Clear-Com Applications:
Refer to your Clear-Com system documentation for intercom cable wiring and
connection details.
Desktop or Rackmount Installation
For desktop use, install the four supplied rubber feet to the bottom of the
unit. Do not obstruct the cooling vents when using the unit on a desktop.
For rack mounting, use an optional Audiocom Rackmount Kit. Several kits are available to meet the requirements of your particular system. Follow the assembly instructions supplied with the rack mount kit.

FIGURE 4. Typical connections using a single PS-2001L Power Supply to power two channels.
FIGURE 5. Typical connections using on SPS-2001 Power Supply for two intercom channels. The two program sources are monitored independently by their intercom channels. All audio (program and intercom) is monitored as a monaural mix in the SPS-2001 speaker. The US2000A is set for monaural speaker output (default).
FIGURE 6. Adding an SPK-1000 to the example in Figure X. The two program
sources are monitored independently by the intercom channels. The SPS-2001
monitors intercom channel 1 and program 1.
The SPK-1000 monitors intercom channel 2 and program 2. The US2000A is sent
for binaural speaker output as described in the US2000A User Manual.
FIGURE 7. Using two PS-2001L Power Supplies to provide a greater capacity on each channel.
FIGURE 8. Using two SPS-2001 Power Supplies to provide a greater capacity on each channel. Using two SPS-2001 Power Supplies also lets you independently monitor and adjust volume for both intercom channels without the need for a separate powered loudspeaker. In this application, the US-2000A should be set for binaural speaker output as described in the US2000A manual.
Power-Up Check
-
Plug in any DC wallpacks that are being using with indi- vidual intercom stations.
NOTE : If you plug in DC wallpacks after applying power to the PS2001L or SPS-2001, you may get an overload indication. This is because the stations that are being powered by wallpacks will draw current from the units until their own DC wallpack supplies are connected. To correct the problem, plug in the DC wallpacks. -
Plug in the AC power cords for any connected PS-2001L or SPS-2001 Power Supplies. The channel status indicators should be green.
-
If a channel status indicator turns red during operation, locate the short or overload that is causing the problem.
Once the short or overload is corrected, the Power Supply should reset itself and the overload indication should go away.
