1.1.3 Material Handling Precautions: Storage
CAUTION
Improper Storage
Store this equipment properly
• If equipment is to be stored prior to installation, it must be protected from the weather and kept free
of condensation and dust.
Failure to follow this instruction can result in equipment damage
1.1.4 Material Handling Precautions: Fasteners
DANGER
Foreign Object Damage - FOD
This equipment may contain fasteners that may come loose - torque properly.
• Only use fasteners of the same type as the one originally supplied with the equipment.
• Use of incorrect combination of gaskets, bolts and nuts can create severe damages to the product
installation and create safety risk .
• You need to know what base the light fixture will be installed in, in order to chose the correct gasket,
bolts and nuts.
• Bolt type, length, and torque value are determined by type of base, height of spacers used, and clamp
force required in FAA Engineering Brief No 83 (latest revision).
• Due to the risk of bolts vibrating loose, do not use any type of washer with the fixing bolts (such as
split lock washers) other than an anti-vibration washer. Anti-vibration washers as defined in FAA EB
83 (latest edition) must be used. For installations other than FAA, use the base can manufacturer's
recommendations.
• Always tighten the fasteners to the recommended torque. Use a calibrated torque wrench and apply
the recommended adhesive type.
• Obey the instructions of the adhesives necessary for the fasteners.
Failure to follow these warnings may cause the fasteners to loosen, damage the equipment,
potentially to loosen the equipment. This can lead to a highly dangerous situation of FOD, with
potential lethal consequences.
Note
To minimize the risk of errors, the ADB SAFEGATE Sales Representative will have information on which gasket goes
with which base. This information is also provided in the product Data sheets, the User Manuals and the Spare Part
Lists.
CAUTION
Use of incorrect combination of gaskets, bolts and nuts can create severe damages to the product installation and
create multiple safety risks.
To obtain a safe and watertight installation the O-ring and retaining bolt stated in the document must be used.
You need to know what base the light fixture will be installed in, in order to choose the correct gasket, bolts and nuts.
Failure to follow these cautions can result in equipment damage or aircraft FOD.

Copyright © ADB Safegate, All Rights Reserved

3.0 Introduction
RELIANCE - the all in one revolution
The RELIANCE inset light is a bi- or unidirectional low-protrusion light-emitting diode (LED) fixture and available in three
versions:
•RELIANCE – a LED light fixture with integrated fail open technology with CCR monitoring
compatibility.
•RELIANCE IQ – a RELIANCE with additional and integrated intelligence (IQ) in a built in converter for
individual monitoring and control, based on RELIANCE Intelligent Lighting, ADB SAFEGATE's Individual
Light Control and Monitor System (ILCMS).
•RELIANCE IQ0 – RELIANCE IQ light fixture with disabled IQ (ILCMS) functionality. Non-MON light
fixture with possibility to activate IQ at a later stage.
Note
RELIANCE IQ light fixtures are not fail-open light fixtures. When IQ is activated the monitoring as well as the control
functionality is handled by the ILCMS system.
The inset light fixture is a 8'' or 12'' unidirectional low-protrusion LED light fixture.
The fixture can be installed in standard 8'' or 12'' bases, in existing or new airfield lighting systems. The light fixtures are ready
for installation, each unit supplied completely assembled, tested and sealed. The electrical connection is with one or two
secondary cable to a transformer(s), equipped with an FAA L-823 plug (style 6). Each unit is individually packed in a durable,
cushioned and corrugated cardboard box, labeled with its reference name and code.
This document describes the installation, operation and maintenance of the inset light fixture.
3.1 Safety Instructions
Warning
PRIOR TO THE COMMENCEMENT OF WORK ALL ELECTRICAL SERVICES MUST BE ISOLATED FROM THE SUPPLY AND
CONNECTED TO EARTH. FULL DETAILS OF THE WORK INVOLVED MUST BE GIVEN TO THE AUTHORIZED PERSON
RESPONSIBLE FOR THE ELECTRICAL ENGINEERING SERVICES AT THE AIRPORT WITH REGARD TO THE DURATION OF
THE WORK AND SO ON... IT IS RECOMMENDED THAT PRIOR TO STARTING ANY CUTTING WORK THE NATURE AND
LOCATION OF SERVICES SUCH AS CABLE DUCTS AND SO ON. SHOULD BE IDENTIFIED ANY INSTALLATION OR
MAINTENANCE WORK SHOULD ONLY BE CARRIED OUT BY TRAINED AND EXPERIENCED PERSONNEL.
HIGH LIGHT INTENSITY! DO NOT STARE DIRECTLY INTO THE LIGHT BEAM AT A CLOSE DISTANCE.
3.2 Description of the Runway Guard light fixture
The runway guard lights warns the pilots, and drivers of vehicles when they are operating on taxiways, that they are about to
enter a runway. The inset runway guard lights are alternately yellow flashing lights that are installed across the taxiway.
3.3 Description of the Stop Bar light fixture
The stop-bar lights consist of a row of unidirectional inset red light fixtures. The stop-bar is provided at the runway holding
position and is an important tool to reduce the risk for runway incursions of aircraft and vehicles.

3.6 Selection of Isolation transformer
3.6.1 2.8-6.6A system
An Isolation transformer in a series system has a specified current ratio (normally 6.6/6.6 A) that is considered to be fixed as
long as the load does not exceed the nominal wattage of the transformer.
Most manufacturers specify a certain spare capacity (20-30%).
When the load exceeds the nominal wattage, the transformer begins to saturate, the current ratio drops as a function of the
overload. To avoid this current drop (intensity drop) the nominal wattage should not be exceeded. It is even more important
in a system with RELIANCE IQ where the IQ function adds a secondary load for its power consumption.
Note
The RELIANCE fail open is not to be connected to transformers larger than 100W. A correct calibration of the CCR is
important to achieve an accurate fail open response.
UM-0197, Rev. 1.0, 2019/11/19 11
Copyright © ADB Safegate, All Rights Reserved

The secondary load of an Isolation Transformer in a RELIANCE/RELIANCE IQ system includes:
•Lamp load
•Cable losses (secondary cables)
•IQ function load (Option)
3.6.2 Light fixture load
This load must be considered when calculating the total CCR load.
L-852G(L) - Runway Guard Light (RGL-I) 25 W
L-852S(L) – Stopbar Light (SB-I) 16 W
3.6.3 Cable losses (secondary cable)
The cable between the Isolation Transformer and the lamp adds losses that cannot be ignored, for example:
2.8-6.6A Operation
2.5 mm2 Cu-wire: 0.6 W/m
4 mm2 Cu-wire: 0.4 W/m
2A Operation
2.5 mm2 Cu-wire: 0.06 W/m
4 mm2 Cu-wire: 0.04 W/m
Note
Cable lengths should not exceed 100 m.
3.6.4 IQ function load (Option)
With IQ enabled, an additional load of 12 W need to be added to the transformer calculations
Note
RELIANCE IQ is not to be connected to transformers smaller than 65W.
3.6.5 2A system
When dimensioning the isolation transformer size for a 2A-system (a series circuit with RELIANCE IQ 2A which is only
supposed to run at 2A), it is important to know that the regular method by adding up the total wattage on the isolation
transformer secondary side, cannot be used. This is because a standard isolation transformer 6.6A/6.6A is marked with a
maximum wattage running at 6.6A. According to the Lenz Law of Induction, the dimensioning property of a transformer is the
total voltage, and not the wattage, of the secondary side of the transformer in a 50/60Hz series circuit system.
The consequence in a 2A-system is the wattage marked on a 6.6A/6.6A isolation transformer must generally be multiplied by
the factor 0.3 to find the total wattage which can be supplied from the transformer without saturating.
Note
The same dimensioning method must be used for a CCR, as the transformer kVA-size marked on a CCR is normally
calculated at 6.6A, not at 2A. There are also more constraints to consider such as spare capacity. For more information,
contact Safegate for a complete CCR dimensioning procedure.
