RB709U-NB Relay Output Universal Receiver

Designed to Work with Most Brands of Gate and Door Openers

The RB709U-NB digital receiver is a wireless radio control designed for use with automated gate openers and garage door openers. The receiver has two channels for receiving signals from two activation devices, such as transmitters, multi-button transmitters, or wireless keypads.

Mounting the Receiver

Consider the following when mounting the receiver:

• The standard receiver cable length is 10 feet (3.05 m).
• For exterior applications, run the cable through PVC conduit to protect it from damage.
• DO NOT run the cable in conduit containing AC wiring.
• The receiver range can vary from 50 to 100 feet (15.2 to 30.5 m) depending upon weather, topography, and external interference.

Note: Do not mount upside down in exterior applications.

Connect Receiver to Relay Inputs and Power

The receiver connects to the gate operator or door opener's relay inputs and a power supply.

Power Supply: Connect to an 8 to 24 Volt AC/DC power supply. The red wire connects to positive (+) and the black wire connects to negative (-).

Channel 1: Connect the green wire to Channel 1 (COM) and the blue wire to Channel 1 (To N/O Contact).

Channel 2: Connect the brown wire to Channel 2 (To COM) and the yellow wire to Channel 2 (To N/O Contact).

Programming the Receiver

To program transmitters or other access devices to the RB709U-NB receiver:

1. Press and hold the transmitter (device) button to be learned.
2. Press the 'LEARN CH1' (or 'LEARN CH2') button on the RB-709U-NB receiver for 1-2 seconds or until the red LED turns on, then release the button.

Note: When the correct code is received and the corresponding relay output is activated, the red LED will turn on.

Check Operation After Programming:

• Press Transmitter (device) button, #1 - RED LED blinks once to confirm.
• Press Transmitter (device) button, #2 - RED LED blinks twice to confirm.
