LiftMaster 850LM 3-Channel Universal Receiver Instruction Manual

LiftMaster 850LM 3-Channel Universal Receiver

APPLICATION

The receiver can be used as a single 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 receiver is not for use with MyQ® enabled garage door openers or devices.
Each channel is compatible with a certain number of remote controls and keypads. Refer to the list below:

• CH1: 50 remote controls and 2 keypads
• CH2: 20 remote controls and 2 keypads
• CH3: 20 remote controls and 2 keypads

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 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.

To prevent possible SERIOUS INJURY or DEATH from electrocution:

• Be sure power is NOT connected BEFORE installing the receiver. To prevent possible SERIOUS INJURY or DEATH from a moving gate or garage door:
• ALWAYS keep remote controls out of reach of children. NEVER permit children to operate, or play with remote control transmitters.
• Activate the gate or door ONLY when it can be seen clearly, is properly adjusted, and there are no obstructions to door travel.
• ALWAYS keep the gate or garage door in sight until completely closed. NEVER permit anyone to cross path of a moving gate or door.

WARNING

To prevent possible SERIOUS INJURY or DEATH, the use of CONSTANT OPERATION on residential openers is PROHIBITED.
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.

WIRING

Refer to your commercial door operator or gate operator owner manual or wiring diagrams for specific wiring information.

INSTALLATION

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, 15 ft. or 86LMT, 25 ft.).

1. Select a location for the receiver which allows access to the terminals and space for the antenna. Ensure antenna does not touch metal surfaces. DO NOT bend or fold the antenna.
2. Fasten the receiver securely with the hook and loop fasteners (provided) or screws (not provided).
3. After installation is complete, connect the power. You may use an 85LM plug-in or 95LM wired-in transformer, or power provided from your operator (9-30 V AC, 9-34 Vdc or see power ratings on the next page). 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 garage door moves to the closed position.
