Statement of Warranty
Warranty – LED Light Source Products FAA EB67D Products manufactured by Airport Lighting Company (ALC)
which use LEDs as a light source are warranted against mechanical and physical defects in design or manufacture
for a period of 2 years from date of installation per the applicable FAA Advisory Circular and against electrical
defects in design or manufacture of the LED or LED specic circuitry for a period of 4 years per FAA EB67D. ALC will
correct such defects by repair or replacement, at its option, provided the products have been properly handled and
stored prior to installation, properly installed and operated after installation, and provided further that the Buyer
has notied ALC in writing within the warranty period and within a reasonable time after notice of such defects.
Refer to handling, storage, installation and operational instructions for proper procedural guidance that must be
followed to maintain warranty provisions.
This warranty is in eect for the specied term as long as the equipment, in ALC's judgment, has not been altered in
such a way as to aect the equipment adversely, subject to accident, negligence, improper storage, and has been
operated and maintained in accordance with accepted FAA guidelines as described in AC 150/5340-26 and ALC’s
published operational guidelines.
ALC reserves the right to examine products about which a claim has been made. Equipment must be presented
in the same condition as when the defect was discovered. ALC also reserves the right to require the return of
equipment to establish any claim.
Disclaimer: ALC's obligation under this warranty is limited to repair or replacement of defective equipment sold by
ALC at no cost to Buyer. This does not include any other costs such as the cost of removal, shipping, or installation
of the defective part or repaired or replaced product, including labor or any consequential damages of any kind.
Warranty services provided under this agreement do not assure uninterrupted operations of LED illuminated
equipment. ALC shall not be liable for any indirect or consequential damages.
ALC's liability under no circumstances will exceed its sales price of the products claimed to be defective. All
transportation costs under this warranty are the responsibility of the purchaser. Replacement parts and/or
equipment provided under this warranty are covered under the same terms until the expiration of the original
warranty period that began upon the rst installation of the equipment.
This is ALC's sole and exclusive warranty with respect to the equipment sold to the Buyer. There are no
express or implied warranties of tness for any particular purpose or any implied warranties other than those
made expressly herein.
ALC shall not be liable to the purchaser of this product or third parties for indirect or consequential damages, or for
damages arising from the use of any options or parts other than those designated by ALC as approved products.

Theory of Operation
The Airport Lighting Company LED PAPI provides benecial visual approach slope guidance to assist the pilot of an
aircraft in ying a stabilized approach.
The FAA Type L-880 PAPI system consists of 4 Light Housing Assemblies (LHA) located adjacent to the origin of the
glide path. Each LHA is installed at an oset from the desired glide path, which is midway between the central pair
of LHAs. The outer pair are slightly more oset from the glide path than the inner pair. This conguration provides
an increasing number of white signals as the incoming aircraft deviates above the intended glid path, and an
increasing number of red signals as the incoming aircraft deviates below the desired glide path. An approach along
the desired glide path will yield two red signals and two white signals.
The FAA Type L-881 PAPI system consists of 2 LHAs installed at angles equally above and below the glide path. An
approach along the desired glide path will yield one red signal and one white signal.
The ALC LED PAPI includes a mercury-free electronic failsafe inclinometer to prevent operation if an LHA is raised
between 0.5 and 1.0 degrees or lowered between 0.25 and 0.5 degrees from its set angle.

Each LHA includes a factory molded power and communications cable that will plug into a factory molded
receptacle secured to a baseplate and mounted at grade.
The receptable for a Style A Primary LHA is secured to the baseplate rst by attaching an ALC #900 cable clamp
(included in 88-09000 mounting kit) to the molded end.
Use the baseplate’s cable clamp and mounting hardware to secure this assembly to the baseplate.
Install the baseplate onto the base can to prepare for LHA connection
The receptacle for a Style A Secondary or Style B LHA passes through the baseplate opening. It is held above the
opening by attaching an ALC #900 cable clamp (included in 88-09000 mounting kit) to the molded end.

Installation of the LHA
The Airport Lighting Company LED PAPI is congured for quick and simple installation and aiming. Typically, the
contractor need supply only 2”EMT for the legs and 1-1/4”liquid tight exible conduit.
Except in situations with special siting considerations, the center of the lens must be within in +/- 1 inch of a
horizontal plane that is within +/- 1 foot of the elevation of the runway centerline at the intercept point of the
visual approach angle with the runway.
Establish the height of this plane above mounting grade for each LHA and cut three pieces of EMT to 13”less
than this.
Assemble each leg and put in its place. Remove the top ange and hex nuts. Lower the LHA on to the lower ange
nuts. Replace the top ange and hex nuts. Do not tighten the top ange nuts until after leveling and tilting the
unit. Use the hex nuts to jam the ange nuts in place.
Run the LHA whip through contractor-supplied 1-1/4”liquid tight conduit from the elbow at the LHA to the
straight connection at the frangible coupling, connecting at grade with the whip from the distribution box in the
L-867 base. In Style A installations, the nal LHA in the sequence will have no distribution box in the L-867 base
and will be connected to a cable run from the previous LHA’s L-867 base can.

Proper Grounding
Each LHA is equipped with a grounding lug. Install a grounding wire connecting this lug to a ground rod. Install a
bare ground wire around the perimeter of the entire LED PAPI system and attach it to each of the ground rods.
Ground Lug
The ground lug position is inverted for shipping. Remove the hex screw with a 5/32 bit to rotate the lug 180° prior
to inserting the ground wire.
