StatementofWarranty
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

TheoryofOperation
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 form 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 FAA Style A PAPI is designed for use with an AC voltage input. The ALC LED PAPI includes an 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.

Installationand wiringof the PDU
The ALC LED PAPI makes use of factory supplied cables and connections to eliminate any need for splicing.
Connections from the Line Power and Remote Control or Current Sensing are made in the Power Distribution Unit.
• After mounting the PDU to the rack, connect the two incoming power lines to TB-1 L1 and L2.
• Connect the Remote Control or Current Sensing wires to the input side of the terminal block.
• Connect the free leads of the 4-conductor PDU-LHA cable per the desired conguration
(be sure to match this with the connections in the Primary LHA).
• For Local (Photosensor) Control, leave the jumper in place at REM, and connect the Yellow and
White/Yellow wires to REM 1 and REM 2. In the Primary LHA, the Yellow and White/Yellow wires
will be connected to Power Conditioning Board 88-00400 J5-1 and J5-2.
• For Remote Control, remove the jumper at REM and replace with wires from a dry contact relay.
Continue as for Local Control.
• For Runway Interlock, connect wires from an L-830 to the top of CCR. Connect the Yellow and
White/Yellow wires to CCR1 and CCR2. In the Primary LHA, the Yellow and White/Yellow wires will
be connected to Power Conditioning Board 88-00400 J5-3 and J5-4.
• Monitoring connections to the system are made at the top of MON, and run from MON1 and
MON2 to Power Conditioning Board 88-00400 J5-5 and J5-6.
