Chamberlain 323LM User Manual

The receiver can be used with a multi-function remote control to operate three residential garage door openers, or with a three-button door control to OPEN, CLOSE or STOP a commercial garage door opener. Not for use on residential fail-safe operators.

INSTALLATION

The receiver and antenna use TV Type F coaxial connectors. The antenna can be plugged directly into the receiver or mounted to a bracket and connected to the receiver with Model 86 Coaxial Cable Kit, depending on your requirements.

Select a location for the receiver which allows access to the terminals and space for the antenna (as far from metal structures as possible and preferably with the antenna in an upright position). Fasten the receiver securely with screws through the two holes provided in the cover flanges.

To use the receiver with a 3-button door control and a commercial door opener:

Consult your manufacturer’s control connection diagram for instructions on connecting two or more 3-button control devices.

Figure 1.

• Use a screwdriver to pry open the receiver cover.

NOTE: The slide switch is factory set to the N.C. position (otherwise the opener will not operate). Verify this setting. Re-connect power to the opener and the accessory transformer, if used.

Figure 1

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 gate or door ONLY when it can be seen clearly, is properly adjusted, and there are no obstructions to door travel.

• ALWAYS keep gate or garage door in sight until completely closed. NEVER permit anyone to cross path of moving gate or door.

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