3-Channel Receiver
Model 323LM
OWNERS 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.
WARNING
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.
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.
• ALWAYS keep gate or garage door in sight until completely closed.
NEVER permit anyone to cross path of moving gate or door.
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.
WARNING
To prevent possible SERIOUS INJURY or DEATH, the use of
CONSTANT OPERATION on residential openers is PROHIBITED.
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.
WARNING
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.
• Use a screwdriver to pry open the receiver cover.
NOTE: The slide switch is factory set to the N.C. position (other-
wise the opener will not operate). Verify this setting. Re-connect
power to the opener and the accessory transformer, if used.
