1. INTRODUCTION
In this section you can find a general description and safety instructions related to the
installation and usage of the fitting.
PRT3 is a flood light that allows lighting of Heliport Touchdown and Lift Off area
(T.L.O.F).
The fitting has many advantages and special features:
Uses the standard R7s 500w linear halogen lamp.
Small size and weight.
Sturdy design.
High efficiency.
Easy access to all components.
Easy installation: mechanical installation and electrical connections are easy to
carry out.
The adjustable light beam is based on a fixation system (Fixation Stirrup and
fixation Holes).
Easy maintenance; replacement of a defective lamp is easy.
Can be equipped of an optional PRT G3 Louver.
SAFETY INSTRUCTIONS1.1 Make sure you read this section and are familiar with safety precautions before any
work is started.
1.1.1. Product Safety
Airfield lighting fixtures in a constant current circuits are connected in a circuit via
isolating transformers with currents between 2.0 –6.6A in the primary circuits.. The
primary voltages, depending on the circuitry, are usually several kilovolts and
therefore lethal. Although the open circuit voltages of the isolating transformers are
much lower, the peak voltage while opening the secondary circuit under current is
also hazardous. So it is vitally important to follow all the safety regulations with
adequate circumspection.
In the design of this equipment all the practical safety aspects have been taken into
account. It is also important to strictly follow existing international or national
regulations, the instructions established by civil aviation authority or airport operator
and the following instructions.
1.1.2. Electrical Maintenance
Valid safety regulations must always be followed. Never carry out any maintenance or
maintenance measures before the current is confirmed as safely disconnected. Use
extreme caution when disconnecting or connecting high voltage primary connectors.
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
AUTHORISED 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 THE LIKE SHOULD BE IDENTIFIED. ANY INSTALLATION OR MAINTENANCE
WORK SHOULD ONLY BE CARRIED OUT BY TRAINED AND EXPERIENCED
PERSONNEL. ALSO, WHEN WORKING ON CIRCUITS USING AIRFIELD SMART
POWER SYSTEM (ASP) THE SCM MUST BE TUNED OFF.
1.1.3. Mechanical Maintenance
When maintaining mechanical components, it is important to follow the instructions for
electrical maintenance.
DESCRIPTION OF THE FITTING1.2 PRT3 is a flood light that allows lighting of Heliport Touchdown and Lift Off area
(T.L.O.F) as recommend by ICAO in the paragraph 5.3.8 of the Volume II of the
Annex 14.
DELIVERY OF THE FITTING
1.1 Each light fitting is composed of three subassemblies:
1. The PRT3 fitting without lamp and louver.
2. The lamp E27 lamp.
3. The louver (Option).
Each unit is individually packed in a durable cardboard box, labelled with its reference
name and code.
For more information, see www.safegate.com.

The screw tapping of the frangible support can be either 2 in. NPS (American
standard - 11.5 threads per inch) or 2 in. BPS (British standard - 11 threads per inch).
Check support and base tapings fit.
The following tools and accessories are required for installation and removal of the
unit:
Standard tools and accessories:
One set of open end wrench
One set of screwdrivers
One cutting pliers
One wire stripper
One cutter
One brush or cloth
The installation steps refer to:
1. Fixating and aligning the fitting
2. Electrical connections
3. Opening/ closing the fitting
4. Mounting the lamp in the fitting
5. Mounting the louver on the fitting

FIXATING AND ALIGNING THE FITTING2.1
To enable the fixation of the PRT3, its fixation stirrup have the following 3 fixation
holes (see Fig 1):
two holes of diameter 6.5 mm
one hole of diameter 8 mm
FIG 1
1.2.1. Adaptation of the Fixation Stirrup
The fixation stirrup allows, by default, an angle adjustment between 0° and 90° (see
Fig 2).
FIG 2
FIG 3
Additionally, the fixation stirrup allows an angle adjustment between 0° and 180° (see

3. MAINTENANCE
In this section you can find a description of the different steps for the maintenance of
the fitting.
Before you start, make sure you have read and understand §1.1 Safety Instructions.
Find out the location of the light unit that needs maintenance. If the purpose is to
replace an existing light unit with new one, make sure that corresponding unit is
available.
WARNING! WHEN A FITTING HAS BEEN REMOVED FROM ITS SUPPORT, THE
BASE MUST BE EITHER FITTED WITH A COVER OR A RESERVE FITTING PUT
IN ITS PLACE.
IT IS RECOMMENDED THAT ONLY AUTORIZED PERSONNEL DISASSEMBLE
FITTINGS WITH PRIOR AGREEMENT FROM SAFEGATE.
BASIC MAINTENANCE PROGRAMME3.1 There are recommended maintenance tasks to ensure that the equipment is in correct
operating condition.
Maintenance tasks
Weekly
Visual inspection of the fitting.
Removal of dust from external surfaces of the fitting.
Monthly
Check of the optical window, check for mechanical damage.
Check for proper fixing of the fitting in its support.
Yearly
Detailed inspection of the fitting.
Check of the body resistance, check for mechanical damage
(for example cracks around prism windows).
Clean of the optical windows.
A daily function check is referred to in the document:
ICAO, Airport Services Manual Part 9, Airport Maintenance Practice and FAA AC
150/5340-26A, Maintenance of airport visual aids facilities.
The light is designed for outdoor operation, however storing the light outside without
using it is a risk for damage to light components. For a longer storage time (more than
a week), it is recommended to store the light indoors in a dry and dust free
environment and at room temperature. Proper storage ensures trouble free
replacement procedures. It is strongly recommended not to store any electrical
equipment outside.
Note: Only the most common maintenance procedures are instructed in following
paragraphs. Construction of the luminaire allows that it can be fully disassembled and
all the parts can be replaced if needed.
WORKSHOP MAINTENANCE3.2 Before you start, make sure you have read and understand §1.1 Safety Instructions.
The workshop maintenance refers to following:
1. Opening/ closing the fitting
2. Replacing the lamp
3. Replacing the louver
4. Replacing the front glass

Check in to the future
How many aircraft can your
airport handle today?
Can this number be increased
without adverse effects on the
airport’s safety level?
It is a known fact that traffic
volume will rise in the foreseeable
future. More movements will
demand monitoring of the entire
airport. Requirements will be
sharpened and the development
of an integrated system
controlling not only ground
movements but also air traffic
close to the airport is of the
highest interest.
The International Civil Aviation
Organization (ICAO) already
describes A-SMGCS, Advanced
Surface Movement Guidance and
Control System, as the answer to
the future modern airport need to
control the entire airport space in
one superior system.
To a larger extent than today’s
systems, A-SMGCS will rely on
automated processes to give both
pilots and traffic controllers exact
information about positions and
directions. Safegate Group
delivers complete A-SMGCS
solutions already, as well as all
vital parts relating to it.
Safegate Group can check your
airport into the future
