WARNING
Install the control station and receiver where the
door or gate is visible, but away from the door or
gate and its hardware. When a receiver is used to
activate a commercial door opener, a reversing
edge MUST be installed on the bottom of the door.
Failure to install a reversing edge under these
circumstances may result in serious injury or death
to persons trapped beneath the door.

INTRODUCTION
The ACRx2000 is a radio receiver which controls a gate or door
opener. It can recognize as many as 1,000 different transmitters.
It assigns a unique identification code to the user of each
transmitter, and can produce a record of when each one is used to
gain access. The ACRx2000 can be easily programmed by any
authorized person to add new users, remove users, suspend users
temporarily, or open the gate or door by pushing one button. It
can be connected to a computer for additional control and
recordkeeping functions.
1000 users with unique radio codes . Any combination of 60, 80, 90, 400, 900 series transmitters and
keypads. Supports Dip, Billion, “Security +, and “Homelink” code formats. Each radio code can have a 5
digit alpha-numeric user name assigned to it.
Terminal block inside case. Two screws each for power, relay output, and command.
24 V AC/DC or 12 V DC.
Relay switching controlled by radio transmitters, or GRANT ACCESS button on control panel, or external
push-button.
Relay Switches Up to 3 Amps at 37 VAC max.
The ACRx2000 is mounted in an 11" x 13" x 6" fiberglass enclosure, with an integrated hinged lid. All
electrical connections can be made through a conduit hole; a type-F connector is available externally for
antenna mounting.
16 Character non-backlit, LCD display
Time and date are maintained by a real time clock with battery backup. Expected battery life is 10 years.
An RS-232 interface is provided. This interface is 1200-9600 Baud, 8 bits, no parity, 1 stop bit. This
allows use of a computer or printer to record access transactions. This interface can also be used to
back up code memory to a computer with the use of Microsoft Windows-compatible software available
from Lift-Master.
Once the ACRx2000 is installed, it may be programmed by
installer or by the custodian of the gate. The same procedures
the
are used to make changes at a later time.
INSTALLATION
Mechanical and electrical installation must be performed by
qualified, professional service personnel. Knowledge of electrical
codes may be necessary when wiring AC power and certain door
actuators. If in doubt, consult with Lift-Master commercial
product service at 1-800-588-2806.

ACRx2000 & ANTENNA MOUNTING INSTRUCTIONS
Mounting the Box
Choose a location for the ACRx2000 control box which is:
• Protected from tampering
• As close to the approaching vehicles as possible for best
reception.
• Suitable for permanent attachment by mounting screws.
• Accessible to necessary wiring.
Hold the ACRx2000 control box in its intended mounting
location. Make sure the cover opens freely, with the display and
controls at a comfortable height and angle for viewing and use.
Use the holes in the ACRx2000 box for marking and drilling
attachment holes.
Antenna Placement
For best range, placement of the antenna is crucial. Follow
these guidelines for best results.
•Make sure there is no interfering signal an the same channel as
the ACRx2000. You can monitor channel activity with the
Liftmaster M-18 Test Set. On-channel interference is not only
due to transmitters, but can also be caused by computing
devices, security systems, and other nearby electronic devices.
Power invertors and battery chargers are known sources of
interference.
• The ACRx2000 antenna system can be configured in several
ways. Each installation is different, so there is no best antenna
system. Try the different configurations of antenna placement
until the best range is encountered. Do this BEFORE hard mounting the antenna and permanently routing the cable.
The typical antenna configurations are as follows on page 3:
• The antenna must not be next to, or enclosed in, metal.
• Place the antenna outside of any housing, box, or building,
even if the housing is not made of metal. Non-metallic
structures can contain conduit, metallic-foil insulation, or be
painted with metallic paint.
• Place the antenna as high as possible, in sight of the expected
location of the transmitters. This is very important.
• Consider the direction from which the transmitters will be
used. Place the antenna so that there are no structures or metal
obstructions between the transmitters and receiving antenna.
• If longer coaxial cable is needed, do not splice cables together.
Instead, purchase a ready-made cable of the desired length from
a radio/tv store. Use 75-ohm cable with CATV connectors
(also called type “F” connectors).
WIRING INSTRUCTIONS
Wiring requirements
Power can be provided with an 85LM wall mount transformer or
Radio Power from a gate operator (17 to 37 V AC/DC at 150
mA or 12 VDC at 200 mA minimum.)
Using an 85LM wall mount transformer: Install the voltage
select jumpers (J4 & J6) in the 24v position and plug the
transformer jack into the receptacle to the right of the voltage
jumper. Wire the relay contacts to Push Button and Common as
shown in the wiring diagram
Using gate/door operator power: Install the voltage select
jumpers (J4 & J6) in the position that matches the power
supplied by the operator. Wire ACRx2000 to the operator as
shown in the wiring diagram.
WIRING DIAGRAM
WARNING
The ACRx2000 uses low voltage wiring only. Attach
the ACRx2000 only to circuits or devices that are NEC
Class 2 (less than 37VAC). Do not run wires to or from
the ACRx2000 in any conduit or box where there are
AC supply (120VAC) circuits. Failure to follow this
warning could result in electrical shock or fire and
damage to the ACRx2000.
