LC-36A ADDENDUM
INSTALLING THE LC-36A LIGHT CURTAIN
ON NON-MONITORED OPERATORS
APPLICATION
When specific power and terminal configurations exist and
additional door protection is required, the LC-36A Light Curtain
can be installed on non-monitored operators from manufacturers
other than LiftMaster by following these instructions.
Although this procedure has been tested with some operators,
LiftMaster does not guarantee this method will work with all
operators.
• LiftMaster CPICARD
• LiftMaster CPS-OPEN4 Photoelectric sensors
For installs with existing photoelectric sensors, they MUST be
replaced with LiftMaster CPS-OPEN4 photoelectric sensors. NO
OTHER PHOTOELECTRIC SENSORS ARE RECOMMENDED FOR
THIS APPLICATION.
• LiftMaster 100MAPS External Power Supply (Optional)
If power is not available from the operator, the 100MAPS can
supply the required voltage to the CPICARD.
The operator must have the following functions:
• 24VAC or 24VDC power output terminals and at least 40mA of
output available to operate the LC-36A Light Curtain in addition
to the power required to operate the CPS-OPEN4 photoelectric
sensors (see CPS-OPEN4 manual for more information).
NOTE:
The LiftMaster 100MAPS External Power Supply can be
used to power the CPICARD instead of the 24VAC or 24VDC
output terminals on the operator.
• Non-monitored edge terminal and common terminal
Mount the LC-36A light curtain and CPS-OPEN4 photoelectric sensors as instructed in their respective manuals. Follow the wiring
instructions on the next page.
