Mounting the Fixture

• The ALC-861L Elevated LED fixtures mount to a 1½” – 12 NF base plate or can be specially ordered to mount on a 2” NPS baseplate.
• The fixture ships from Airport Lighting Company ready to be plugged into an appropriate L830 Style isolation transformer with a 6.6amp output.
• Snake the cord through the column and frangible coupling, then plug the fixture into the isolation transformer secondary.
• Thread the frangible coupling onto the baseplate.
• Secure the column to the frangible coupling.

Bi-Directional Fixture Alignment

• The ALC-861L bi-directional fixtures are assembled so that the 2 clasps that hold through the glass lens are on the dividing line of the bi-directional colors.
• Line the ALC-861L up so that a line thru the clasps is perpendicular to the runway and the colors are in the correct orientation.

Leveling the Fixture

• Place a torpedo level along the bottom edge of the light fixture base.
• Using the (3) ¼”-20 hex screws in the base of the fixture adjust the screws until the light fixture is level and tighten to 30 in-lbs.

Final Preparation and Verification

• Wipe the lens clean.
• Power the constant current regulator and check that the LEDs come on.
• Run through all the steps of the regulator and make sure that the light intensity increases as the current is increased.
• The fixture is ready to provide years of quality service.

Wiring Without an Arctic Kit The ALC-861L fixture leaves the factory ready to be connected to a 6.6A output isolation transformer. The secondary of the isolation transformer plugs into the fixture power cord. The power cord connects to 2 tabs on the driver board with quick connect terminals. The driver board connects to the LED light engine with a 2-position inline connector.

Wiring With an Arctic Kit The ALC-861L fixture leaves the factory ready to be connected to a 6.6A output isolation transformer. The secondary of the isolation transformer plugs into the fixture power cord. The power cord connects to the driver board and arctic kit in series. The remaining arctic kit power lead plugs into the remaining tab on the driver board. The driver board connects to the LED light engine with a 2-position inline connector. The driver board connects to the arctic kit control circuit with a 3-position inline connector.
