Lift-master ACRX2000 Manual

Access Control Receiver

ACRx2000

OWNERS MANUAL

To comply with FCC/IC rules, adjustment or modification of receiver and/or transmitter is prohibited, except for changing the code setting and replacing the transmitter battery. THERE ARE NO USER SERVICEABLE PARTS.

WARNING

Disconnect power to the garage door or gate opener before installing the receiver.

Children operating or playing with a garage door or gate opener can injure themselves and others. The garage door or gate could close and cause serious injury or death. Do not allow children to operate the push buttons or the remote control transmitters.

Install the receiver (and any additional push buttons) out of the reach of children and away from all moving parts of the door or gate and its hardware, but where the garage door or gate is visible.

A moving garage door or gate could injure someone under it. Activate the opener only when the door or gate is properly adjusted, you can see it clearly, and there are no obstructions to door or gate travel.

FEATURES

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.

Output Control Circuit	Relay switching controlled by radio transmitters, or GRANT ACCESS button on control panel, or external
	push-button.
Output Control Rating	Relay Switches Up to 3 Amps at 37 VAC max.
Case	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.
Display	16 Character non-backlit, LCD display
Time Clock	Time and date are maintained by a real time clock with battery backup. Expected battery life is 10 years.
RS-232 Interface	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.

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.

Once the ACRx2000 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.

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.

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.
