Universal DC Low Intensity Obstruction Light
Dual Light Fixture
AV-OL-ILAB-12-R-D
& AV-OL-FL810-12-R-D Models
This Avlite dual 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 up to 45 metres above ground, 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 dual light xture can be congured to different operational states. Both light
xtures may be set to operate steady-burning. Alternatively, the dual light xture
may consist of a main light and a standby light. If the main light should ever fail the
standby light will automatically switch on to ensure the obstacle is always clearly
marked.
The light xture incorporates internal diagnostic checking and an alarm contact for
remote monitoring. The alarm relay is energised in normal operation and is released
whenever the LED is not lit.

Safety Information
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andcertiedprofessional.
• 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.
• Do not stare at the LED or shine the LED into your eyes or those of another person.
• Do dispose of the product according to the local laws and regulations for your region, for example,
at a recycling center that accepts electronic devices.
Unpacking, Mounting, Wiring & Setup
Unpackallhardwareandinspectfordamage.Ifthereisanydamage,pleasecontactyourAvliteOfce.
Retain original packing material for possible future use in shipping.
Unpacking
Mounting
Mount the Obstruction Light using its four mounting holes. Make sure the light is horizontally aligned to
guarantee the required beam pattern of the obstruction light.
Installation & Wiring
Beforeproceeding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.
NOTE:

DC POWER CONNECTION
1. Open the top lid by removing a locking pin and nut from one side of the lid. Wire up the light and
connect power to the terminal block. Please refer to Figure 2.
2.Wireasfollows:
• Positive supply (+) = +VDC
• Negative supply (-) = 0V
3. Close the lid using the locking pin and nut. Make sure the white rubber O-ring remains in place
during that process.
NOTE:
• The unit is designed to operate from a nominal DC voltage from 12V to 48V.
• Use cable in compliance with the effective local electrical code. The cable outer diameter should be
between5mmand10mm.Avliterecommendsthefollowingnumberofcoresandsize[mm²]:2x0.75
or 2 x 1.0
• Color coding may vary depending on country and local regulations.
OPENING AND CLOSING THE LIGHT HEAD(S)
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.

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.

INTENSITY & OPERATION MODE SETTING
Light intensity & operation mode setting for ICAO compliant light xture
ThexturewillbesuppliedwiththeICAOcompliantoptic.
Theobstructionlightwillbepre-settotheintensitysettingspeciedbythecustomer(ICAOTypeAor
ICAO Type B) for a red steady burning Low Intensity Obstruction Light in dusk-till-dawn mode. The
intensity and operation mode is pre-set in the factory and does not need to be set by the user.
If the customer should need to change the intensity or operation mode settings of the ICAO compliant
model they can do this by changing the INTENSITY DIP switch. Please refer to table below for DIP
switch settings and Figure 3 for circuit board location.
Light intensity & operation mode setting for FAA compliant light xture
ThexturewillbesuppliedwiththeFAAcompliantoptic.
The FAA compliant model comes pre-set to the correct intensity for L-810 steady burning red
obstruction light in dusk-till-dawn mode. The intensity and operation mode is pre-set in the factory and
does not need to be set by the user.
If the customer should need to change the operation mode settings of the FAA compliant model they
can do this by changing the INTENSITY DIP switch. Please refer to table below for DIP switch settings
and Figure 3 for circuit board location.
NOTE:
The ICAO Model and FAA Model have their own unique optic. The ICAO model cannot be used for
FAA purposes and the FAA model cannot be used for ICAO purposes. The model required needs to be
speciedatthetimeoforder.

ALARM RELAY OUTPUT
In normal operation the relay is energised
• Terminal contacts COMM and NC of the relay are electrically closed
• Terminal contacts COMM and NO of the relay are electrically open
Whenever the LED is not lit due to a power failure and/or a LED failure the relay will not be energised.
• Terminal contacts COMM and NO of the relay are electrically closed
• Terminal contacts COMM and NC of the relay are electrically open
For location details of the terminals please refer to Figure 3.
Thealarmrelaycanbeconguredinthreedifferentways:
• Relay normal operation (default, as described above)
• Relay inverse operation (inverse functionality of the normal operation, used to conserve power)
• Relay disable (in case the relay is not required, used to conserve power)
NOTE:Thealarmrelayisintendedforlowvoltage(SELV)connectiononly.
