Universal DC Low Intensity Obstruction Light
Single Light Fixture
AV-OL-ILAB-12-R & AV-OL-FL810-12-R
Models
This Avlite light xture is a steady burning, low intensity LED obstruction light
designed to comply with FAA L-810 and ICAO LIOL Type A & B requirements. The
model can be used for marking obstacles which pose a threat to aircraft, such as
telecommunication towers, wind turbines, buildings and other tall structures.
Avlite’s LED obstruction lights offer an ultra bright, energy efcient and cost
effective lighting solution.
The light xture is available in universal DC (12-48VDC). The advanced light optic
uses a single LED for minimal power consumption. The corrosion resistant,
polycarbonate lens is specically designed for use with LEDs to maximize light
intensity and uniformity.
The light xture incorporates internal diagnostic checking and an alarm contact for
remote monitoring. The alarm relay will be released whenever there is a problem
e.g. no power, supply voltage too low, LED failure, etc. The alarm relay will remain
energized during the day when operating normally.
The ICAO model has adjustable intensity settings to allow the user to easily toggle
between 10cd (ICAO Type A) and 32cd (ICAO Type B) light intensities.

Safety Information
• Install the light in compliance with the effective local electrical code(s).
• Mains power should always be disconnected when work is being done in close proximity to
electricalttings,andelectricalworkshouldonlybedonebyalicensedelectrician.
• Operate the light only within the indicated electrical ratings and product usage instructions.
• To ensure that the light and peripheral equipment function safely and correctly, use cable in
compliance with the effective local electrical code.

Unpacking
Installation & Wiring
Before proceding with installation or service, make sure the following conditions are met:
• Ensure the tower or mast is grounded (NO RF HAZARD)
• Check the mast lighting circuit is not faulty
• Ensure power lines are not ‘live’ (NO ELECTRICAL HAZARD)
• Avoid touching live circuits!
• Avoid touching any component or any part of the circuitry while the unit is operating. Do not change
components or make adjustments inside the unit with power on.
Open the Obstruction Light as described. Guide the cable through the cable gland and mount the
bottom half of the Obstruction Light on a mounting pole using the inner thread.
NOTE:
• Make sure the mounting pole is vertically aligned to guarantee the required beam pattern of the
obstruction light
• Make sure the light’s beam pattern is not disturbed by any nearby obstacles
Shorten the cable and close/seal the cable gland.
With the unit open, observe the rear of the PCB mounted in the top half of the Obstruction Light for
terminal blocks and switch settings.
NOTE: Use cable in compliance with the effective local electrical code. The cable outer diameter
should be between 5mm and 10mm.
NOTE: There is no requirement to terminate the relay and/or the serial communication if not used.

OPENING & CLOSING THE LIGHT HEAD
• Remove the locking screw
• In order to open the unit, the top half of the unit should be turned anti-clockwise with respect to
the bottom half. The top half will turn approximately 20mm over a positive “click” before separating
from the bottom half. Attention should be paid to the restriction caused by the internal cabling
which is secured by a cable gland.
• The unit is closed by reversing the above procedure, ensuring the black rubber O-ring remains in
place.

DC POWER CONNECTION
The unit is designed to operate from a nominal DC voltage from 12V to 48V.
Wire as follows:
• Positive supply (+) = +VDC
• Negative supply (-) = 0V

When powered up, the light will constantly check day/night status using its internal ambient light
sensor. The ambient light sensor averages its measurement for 30 seconds.
FAA: By default the lights turn ON when the ambient light decreases to not less than 35 foot-
candles (367.7 lux) and turn OFF when the ambient light decreases to not more than 60 foot-
candles (645.8 lux). These limits can be factory adjusted, if required.
ICAO: By default the lights turn ON when the ambient light decreases to not less than 35 foot-
candles (100 lux) and turn OFF when the ambient light decreases to not more than 60 foot-
candles (150 lux). These limits can be factory adjusted, if required.
If the light detects a LED failure the alarm relay can be used to provide a feedback to the user.
