INTRODUCTION
The ACRx 2 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 ACRx 2 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.
WARNING WARNING
1025 users with unique radio codes (any combination of 60 series remote controls, 80 series remote
controls, 90 series "SECURITY+" remote controls, 66LM keypad, 67LM "SECURITY+" keypad, 466LM
commercial keypad, or 99LM keypad remote control codes). 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 ACRx 2 is mounted in an 8" x 10" x 3" metal box, 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. Keylock provided for securing panel against undesired entry.
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.

OWNERS MANUAL

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.
Once the ACRx 2 is installed, it may be programmed by the
installer or by the custodian of the gate. The same procedures 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.
