The receiver can be used as a single, two, or three channel receiver to control up to 3 gates or commercial door operators. The receiver can also be used with a 3-button remote control to operate the OPEN, CLOSE, and STOP feature on a commercial door operator. The 860LM Weather Resistant Universal Receiver may be mounted in outside locations that may be exposed to rain or moisture. This receiver is not compatible with myQ® enabled garage door openers or devices.

The receiver and antenna use TV Type F coaxial connectors. The antenna can be connected directly to the receiver or it can be installed remotely using a coaxial cable extension kit Model 86LM or 86LMT.

Below are wiring examples. Refer to your commercial door operator or gate operator owner's manual or wiring diagrams for specific wiring information.
SINGLE CHANNEL

TWO & THREE CHANNEL

OPEN/CLOSE/STOP

Each channel is compatible with a certain number of remote controls and keypads. Refer to the list below:
When the channel has reached full capacity for remote controls, all LEDs will blink 3 times. When the channel has reached full capacity for keypads, all LEDs will blink 4 times. Additional accessories can be programmed, however, the newly programmed accessory will replace the first programmed accessory.
NOTE: The receiver can command the operator to close the door or gate by constant pressure. This feature is only available with a wireless control panel Model 885LM). To enable this feature, press and hold the push bar until the gate or door moves to the closed position.

NOTE: This receiver will only allow you to program a button on the remote control to one channel at a time. For example, if the button on the remote control is already programmed to channel 1 and then is programmed to channel 3, the button will be erased from channel 1 and will only work on channel 3.
Repeat the steps above for each remote control you would like to program.
NOTE: If a remote control button is not pressed within 30 seconds, the LED next to the selected Learn button will turn OFF. In that case, repeat the programming.
Press and hold the Learn button for the channel you want to erase. Release the button when the corresponding LED turns off; the memory has been erased.
