RELIANCE LED PAPI Precision Approach Path Indicator Compliance with Standards L-880(L) / L-881(L) AC 150/5345-28 (Current Edition). ETL Certified. • LEDs greatly increase light source life and significantly reduce ongoing maintenance costs and periodic relamping expenses. PAPI Annex 14, Volume 1 (Current Edition) PAPI / APAPI Transport Canada TP 312 par. 5.3.16.12 and Appendix 5B, Figure B-19 DIRECTIVE 2014/35/EU: LVD annex IV & with DIRECTIVE 2014/30/EU: EMC annex IV AP-170 (Aviation rules. Part 170) • Average LED life of 60000 hours under high-intensity conditions and more than 150000 hours under typical operating conditions. • Each light unit uses a maximum 120 W when the heater is active. • Depending on operating mode, light unit uses 62 % to 80 % less energy than traditional light units that use three 105 W lamps, two 200 W lamps or three 200 W lamps. • Unique, sealed optical chamber is designed to prevent dew/frost on LED optical elements. • Low-power design contributes to a lower life cycle cost and lower cost for CCRs and supporting equipment. • Use of LED light source improves safety and pilot recognition by eliminating color shifts typical of incandescent light sources at lower intensity settings. Uses The RELIANCE™ LED PAPI (Precision Approach Path Indicator) system uses a multi-LED array to form a single light channel on each light unit to provide the pilot precise visual information, enabling the approach procedure to be performed with the utmost accuracy and safety. • Digitally controlled heated front glass ensures that the glass is clear of frost/dew within: - 3 minutes when ambient: -6 °F to +131 °F (-21 °C to +55 °C) - 4 minutes when ambient: -38 °F to -8 °F (-39 °C to -22 °C) Type L-880(L) PAPI system consists of four light units located at the side of the runway adjacent to the origin of the glide path. The nominal glide slope angle is midway between the angular settings of the central pair of the four units. If an aircraft is on the correct approach path, the pilot will see two red and two white light indicators. If the aircraft approach is too high, an increased number of white light indicators will be seen. If the approach is too low, the pilot will note an increased number of red light indicators. - 5 minutes when ambient: -67 °F to -40 °F (-55 °C to -40 °C) • Hardened front glass protects the optical lens from sandblast. • Voltage powered systems do not require a separate controller cabinet. Controller functionality is incorporated into the Primary Light Unit. This minimizes installation costs and is compliant with FAA Safety Management System requirements to clear the Runway Safety Areas (RSA) and Runway Obstacle Free Areas (ROFA) of all unnecessary obstacles. Operates on an input voltage of 240 VAC +/-10%, 50-60 Hz and can easily be field configured to operate on 120 VAC +/-10%, 50/60 Hz. Type L-881(L) APAPI system is an abbreviated PAPI system. It is identical to the L-880(L) PAPI system, except it consists of only two light units (instead of four). The nominal glide slope is midway between the angular settings of the two units, and when the pilot is on or close to the correct approach path, the unit nearest the runway will be seen as red and the other unit as white. • Current powered systems operate on either a 3 or 5-step CCR designed in compliance with IEC or FAA requirements • A unique digital display indicating the vertical angle can be read from outside the light unit. This eliminates the need to use a manual aiming device during initial installation and for routine verification of vertical angle setting, minimizing maintenance time. Style A (voltage powered) system is for use with 120 VAC or 240 VAC, 50/60 Hz voltage input. Style B (current powered) system is for use with 6.6 A or 20 A, 50/60 Hz series current input from a CCR. An electronic inclinometer assembly, which is a mercury-free device, is provided on each light unit to monitor the aiming angle of the light unit. FAA certified PAPIs are designed to de-energize all light units if the optical pattern of any light unit is raised more than 0.5° or lowered more than 0.25° with respect to the set aiming angle of the light unit (refer to AC 150/5345-28H). For ICAO and TP312 compliant units, this feature is factory disabled, but can easily be enabled if desired. • In the event of a tilt, the digital display indicates which light unit has tilted along with status indicators and horizontal angle. This allows for quick troubleshooting, minimizing the maintenance effort needed to determine which light unit is tilted. • Light units may be

Power Supply • Rugged lightning protection complies with ANSI/IEEE C62.41- 1991 Location Category C2 given in FAA Eng. Brief 67. Category C2 is defined as a 1.2/50μS – 8/20 μS combination wave, with a peak voltage of 10,000 V and a peak current of 5,000 A. For Style A (Voltage Powered) systems, power is supplied to the primary light unit. For Style B (Current Powered) systems, power is supplied individually to each light unit via a 6.6A 200 W isolation transformer. When used on a 20 A series lighting circuit, a 20A/6.6A isolation transformer must be used to step the current down to 6.6 A. •...

PAPI Light Power Cord Ordering Code The power cord is available in 8 ft (2.4 m) or 18 ft (5.5 m) length. The 8 ft (2.4 m) length is adequate for most installations. For installations that require a longer power cord, the 18 ft (5.5 m) length can be supplied and cut-to-length on-site during installation.
