Uses
Basically Aviation Ground Lighting flashing lights are landing aids for poor
weather conditions. They are switched on when the ­effective range of
steady burning approach lights at full intensity becomes insufficient to insure
adequate guidance. Since it may also be desirable to operate such systems
under good visibility conditions, for instance to facilitate the location of the
runway in urban areas, the use of a 3-level system avoids dazzling.
Flashing lights may be used as:
• Sequenced flashing lights (SFL) in (non-) precision approaches,
• Runway threshold identification light systems (RTILS),
• The combination of the above SFL and RTIL systems
• To add a runway alignment segment to a medium-intensity
approach lighting (system MALSR),
• Lead in (LDIN) approach lights (on request).
Features
• 400 V flash tube for improved overall security compared to 2 kV.
• Low mass elevated flash head incorporates triggering electronics for faultfree firing of flash tube.
• The Flashing Control Unit (FCU) exists in a FCU-1 and a FCU-3 ­version.
The FCU-3 version houses three single FCUs in one common enclosure. User benefits:
■ Lower acquisition and installation costs
■ Perfect balancing of loads over the three phases
■ Easier to service
■ Improved safety thanks to fully protected cable runs
• New high power factor power supply yields lower power consumption, and
eliminate peak inrush currents during capacitor charging phase. Smaller
cross-section cables for input power required.
• The FCU adjusts itself automatically to any input voltage from 190 to 260
V AC, 50 or 60 Hz. Available for single or three phase (3 or 4 wires) power
supply.
• Wiring between FCU and flash head uses standard,
4-core plus earth, low voltage cable.
• Remote control and monitoring via single or dual field bus,
24 or 48 V multi-wire or a combination of both.
• Distance between FCU and flash head:
120 m and over without light output loss or misfiring. Required
energy to reach specified light output is always guaranteed into
the flash tube.
• Microprocessor controlled design allows user-adjustable
­parameter setting and configuration, detailed individual status
monitoring, software update via Flash EEPROM upload, (all
optional) and condensation prevention.
• Lightning surge protection 6,5 kA 8/20 µs included as
standard. Extended protection up to 80 kA recommended for
lightning sensitive areas available as an option.
Combines the best out of two worlds: direct line coupled
and capacitor discharge flashing systems.
A.02.620e
General description
The ADB low voltage capacitor discharge flash light system consists of up
to 32 flashing lights with individual control units. The fixtures are available as
elevated and inset unidirectional applications.
All Flasher Control Units are electrically identical. They can be supplied as
pole mounted cabinets for each individual flashing head or – recommended
– as 3-in-1 units to control three flashing lights from one cabinet only. In the
latter case, the cabinets are mounted on a pedestal, offering the advantage
of a most easy access for installation or servicing even as a complete
mechanical protection of the in- and outgoing cables.
Thanks to the built-in compensation for the cable length, the
FCU-3 cabinets can be placed outside the obstacle limitation area.
Electrical equipment description
The flashing control units are designed for the supply of 400 V DC flash
tubes. The flash energy required for each of the 3 individually adjustable
levels is stored in a capacitor.
The trigger electronics are located in the flashing light.
Any cabinet in the system can be designated as the Local Master Controller
(LMC) by adding a Master PCB. The LMC assures the synchronization
between the cabinets, incorporates the master for the local bus, and serves
as interface between the flashing system and the control system.
Via a standard PC and a dedicated “dongle”* (optional), most of the
parameters as well as the system configuration can be optimized to the
on-site conditions.
The electrical connections between the substation and the FCUs and
between each light fixture and its control cabinet use standard low voltage
cabling. The latter connection can be up to 120 m without loss of light
output.
Remote control is realized via multiwire, single or double field bus or
any combination thereof. All cabinets are equipped with microprocessor
controlled anti-condensation heating.

*Details on application
Electrical supply
The system is powered either from a three-phase (3 or 4 wire) or a singlephase power system, providing a voltage between phases of 190 to 260 V
50/60 Hz.
In case FCU-3 control cabinets are used, the load balancing over the three
phases is almost automatic.
As soon as power is applied, the wiring arrangement allows the anticondensation heater(s) to operate, even while the Flashing Light system is
switched off.

Each flashing unit can be configured in hardware mode by means of
dipswitches, indicating the position of the control unit in the system, and in
the software mode.
The software configuration overrules the hardware configurations and
allows adapting the system irrespective of the hardware address given to
the FCU (dongle required).

Flashing control units (Fig. 10 & Fig. 14)
Preferably the control units are installed outside the safety area. If installed
inside, the installation needs to be frangible. In order to limit the effect of the
jet blast, it is recommended to install the cabinets with their largest vertical
surface parallel to the approach axis.
Flashing lights (Fig. 11 to 14)
The inset light can be mounted on an ADB 12˝ shallow base with 100 mm
Ø central hole (Fig. 11), on a FAA L868-B deep base
(Fig. 12), by means of a 12˝ to 16˝ adaptor ring on a deep
FAA LB-4 base (Fig. 13). Bases need to be ordered separately. When
installing the control units outside the safety area, the elevated flashing
lights can be installed like any other steady burning approach light.

Fig. 11 FFL Dimensions in mm
In case of pole-mounted, 1-in-1control cabinet in the approach, the
elevated light can be installed on top of the pole supporting the individual
control cabinet. In the latter case, all exposed cables need to be suitably
protected.
(See Fig. 14 for typical installation).
Options
• Additional surge protection:
The standard control electronics are protected by MOV’s against over
voltages up to 6.5 kA 8/20 µs. An optional protection for surges up to
80 kA 8/20 µs is recommended for any lightning sensitive area.
• 230 V Mains socket outlet:
FCU boxes can be supplied with built-in socket outlet to ease servicing
activities in the field and at night.

and E-2689a. The aluminium alloy fitting shall be
equipped with a mechanically fastened userreplaceable prism, without making use of sealing

The RTIL or sequenced flashing approach light
system shall consist of low voltage, condenser
discharge flashing units.
The systems shall be in full compliance with ICAO
Annex 14, FAA L-849 the photometry to E-2159,
E-2325, E-2628. E-2689 and Stanag 3316.
Each of the flashing units shall consist of a
control unit and an elevated or inset light
providing a most similar light output, independent
of the distance between the light and the control
unit.
The control electronics shall operate properly at
any input voltage ranging between 190 and 260
V from a single or three phase (3 or 4 wires) 50 or
60 Hz network, without any need for adjustment
taps.
The flashing system shall use a lamp rated 400 V
max. and shall not make use of any high voltage
components, except for the triggering function.
The control unit shall compensate for various
lengths of the cable between the light and the
control unit; there will be no reduction of the light
output for a length up to 100 meters.
The flashing sequence shall be controlled by a
coded signal emitted by one of the control units
designated as „master” for the system and acting
as the local bus master and the interface card to
the airfield lighting control system. Any control
unit of the system shall be able to be used as
„master”.
The communication between the ATC tower and
the flashing system shall be realized either via
a multi-wire cable, one or two dedicated local
buses or a combination of these and shall permit
a complete status monitoring and remote control
of each individual control unit (over a local bus).
The flashing system will be on-site reconfigurable to the conditions prevailing ­on-site
by means of standard laptop PC and a „dongle”.
