Instruction Sheet
General Description
The ACS-101 (Antenna Combiner Splitter 10 to 1) is an
amplified and filtered broadband splitter-combiner. It
allows up to 10 base stations to use only one transmit
and one receive antenna.
The antenna combiner section contains innovative
hybrid coupling, amplifying and matching technol-
ogy to combine 10 transmitters to 1 output with
very low intermod distortion.
ACS-101 Product Features:
The antenna splitter section has broadband input fil-
tering and amplification to maintain signal levels
through the splitters. High output isolation between
ports is also achieved.
The industrial strength power supply of the ACS-101
supplies voltage and current to two outputs on the prod-
uct. Each output can supply up to 5 Amps at 12 VDC.
·Ideal for use with BTR-1, BTR-500, BTR-600, BTR-700 wireless intercom systems.
·Two power outputs to supply up to 10 transceivers (5 on each daisy-chain run)
which makes large systems easier to implement.
·Standard IEC 320 power input connector
·115 VAC or 230 VAC operation
·High-Quality TNC connectors for consistent impedance across the entire frequency range.
·Rack mount brackets included for 19" (482.6 mm) rack

Green - The unit has power.
Red - The unit has overheated and the combiner amplifiers
have shutdown. There is a sensor on the combiner amplifier
heatsink that senses if the heat rises above 75º C (167 F).
2. DC Outlet Fuses - 5 Amp, SlowBlow, 250 VDC. Size is 3AG.

4. DC Power Output Jacks - Threaded 5.5mm x 2.1mm Jacks. 12
VDC up to 5 Amps is available at each jack.
5. Receive Antenna Jack - This TNC female connector is where
the receive antenna connects.
6. Receive Splitter Jacks - These ten TNC Female connectors are
the outputs for the receive signals. NOTE: All unused jacks
should be terminated with 50 Ohm loads (See accessories
listed at the end of this document).
7. Transmit Combiner Jacks - These ten TNC female connectors
are the inputs for the transmitters.
8. Transmit Antenna Jack - This TNC female connector is where
the transmit antenna connects.

System Configuration

Antenna Requirements
The ACS-101 may be used with a variety of anten-
nas. For best results, use a pair of ALP-450 direc-
tional log periodic antennas (See Figure 5) or, the
ALP-600 Bi-directional log periodic antenna (See
Figure 6).
Good results may also be obtained with 1/2 wave
antennas (See Figure 7). All antennas are sold sepa-
rately.
When using 1/2 wave antennas, we recommend us-
ing the higher frequency model when the receivers
operate in more than one band. If the receivers are
more than one band apart, such as yellow and
white, we strongly recommend using the ALP-450,
or ALP-600 depending on the application.
Place the ACS-101 with antennas in a location that
is in direct view of the beltpacks for best results.

Antenna Placement
for Optimum Range and Rack Mounting
For maximum range and when rack mounting, the
antennas must be remotely located.
The ALP-450 and ALP-600 antennas come com-
plete with a variety of mounting hardware and 10
feet (3 meters) of low loss coaxial cable. A combi-
nation mounting bracket with 10 feet of coaxial ca-
ble is available for 1/2 wave antennas (Model No.
AB-2).
Antennas should be placed in a location with a clear
“signal path” to the beltpacks. This “path” should
be as short and free of obstructions as possible. Ob-
structions, such as walls ceilings, and metal objects,
will reduce range and performance.
Rack Mounting
·Rack mount brackets are supplied with the
ACS-101. To attach the brackets, proceed as fol-
lows:
·Align the rack mount bracket with the holes on
the side of the unit. See Figure 8.
·Install flat head machine screws in two holes.
Tighten securely. Repeat on the other side of the
unit. For best alignment, perform the above
steps while the unit and rack brackets are set-
ting on a flat surface.
·Insert the unit into a 19" rack enclosure and in-
sert four screws (not supplied) in each corner of
the rack mount brackets and secure.
Coax Cable
For best results, it is recommended that cable losses
be kept under 4 dB. (Every 3 dB of signal loss results
in a system operating distance reduction of 25%.
See the accessories section of this manual for spe-
cial low loss cable assemblies.
