Section 1: General information
1.1 Scope
This manual provides information about the installation, operation, and maintenance of the OBSTAFLASH LED Medium
Intensity Obstruction Lighting Systems manufactured by OBSTA. The lighting systems described in this manual are Medium
intensity type B and FAA type L-864 obstruction lights
1.2 General description
The OBSTAFLASH Lighting System is an LED medium intensity system manufactured to comply with ICAO annex 14 chapter
6 and Federal Aviation Administration Advisory Circular 150/5345-43. Each system consists of one flash-head, and can be
associated with power supply with ambient light sensor (photocell) and the interconnecting cable. System components are
shown in Figures 1-1 to 1-2
1.2.1 Flash-heads OFC-RR-240
The OFC is an LED medium intensity system manufactured to comply with ICAO annex 14 chapter 6
and Federal Aviation Administration Advisory Circular 150/5345-43J.
The OFC includes :
• A light flash-head with 6 luminous parts.
• A Lamp holder and an interface (Cable gland + terminal connection on the PCB)
The attachment of the flash-head is done with 2 latches. Waterproof is done through an O-ring between the
flash-head and the lamp holder.
1.2.2 Power Cabinet
The cabinet consists of a 230VAC stainless power supply that contains:
- 1 surge protection
- terminal blocks for wiring to the flash-head, external photocell, remote alarms, etc…
- “Remote” position, the lights are in normal operation
- “Night” position, the light is forced in night mode.

Section 2 : Installation
2.1 Unpacking
Carefully unpack each item and remove any internal packing material from the power supply and the OSBTAFLASH. Examine
each item for obvious physical damage. Immediately report any claims to the carrier. Installation drawings is included in the
power supply carton.
2.2 Mounting and preparation
2.2.1 obstaflash beacon
The OBSTAFLASH is usually mounted at the highest point on the structure on a horizontal platform, or as per requirements of
the local Aviation Regulation authority in place at the installation location.
We recommend that the metallic base of the flash-head to be connected through a grounding kit to the local grounding of the
tower.
2.2.3 Ambient Light Sensor P/N100755 (photocell)
If included, the ambient light sensor should be mounted upright, away from artificial light (such as floodlights), and in a location
that will enable its sensor window to have an unobstructed view of the polar sky (eg., pointed north in the northern
hemisphere).
The photocell 48Vdc returns 0V during day time and +48Vdc close in darkness
Input voltage 48Vdc +15/-10%
Output voltage 48Vdc +15/-10% (night time), 0V (day time)

3.1 System components
3.1.1 Light
Flash-head
Latches
Light body
Cable entries
Photocell(option)
3.1.2 flash-head
The flash-head includes 6 optics and 6 led strips that ensure the light output of the light. Each flash-head do
have 2 independent led circuits
3.1.3 Latches
The sealing of the light is ensure but the 2 latches and the O-ring between flash-head and the light body.
3.1.4 Light body
The light body contains the PCB that control the light output. It is very important to ensure the O-ring is
placed correctly while closing the flash-head
3.1.5 Command card (PCB inside the light body)
The command card inside the light ensures:
• The conversion of the power supply input
• The control of the current of the 2 led circuits inside the flash-head
• Setting of the light (master or slave)
• Synchronization of the flashes
• Alarm

3.2 GPS OBSTAFLAH SYNCHRONISEUR P/N : 113746IV2
Option for OFC-CTR-6E-3F-6A-240
113746IV2
The GPS is a PCB powered in 48V and provide 2 output signals to the command card:
- one top sync (and one day/night used without photocell)
Operation :
• The green led (GPS) blinks : the GPS receive the signal
• The red led (D) and the green led (S) blinks : The GPS is not synchronized and sends a top sync to the command card at 15
flashes per minute
• The green led (S) blinks: The GPS is synchronized in day mode and sends a top sync to the command card at 40 flashes
per minute (as per the S3 configuration)
• The green led (S) blinks and the leds (N) & (T) are on: The GPS is synchronized in night mode and send a top sync at 30
flashes per minute (as per the S4 configuration)
If used a day/night info (0V@day/48V@night) is sent to the command card

4.2 Troubleshoot - Malfunction
4.2.1Led indicators
Some indicators (Leds) located on the top on the right of the command card in the event of alarm give a
status of the light, they are identified in white :
D4 : red in case of alarm
D5 : green for led circuit 1 inside the flash-head
D6 : green for led circuit 2 inside the flash-head
D5 and D6 blinks at the same pulse than the circuit 1 and circuit 2 inside the flash-head. D4 normally
blinks also at the same pulse
On the surge protection, a luminous indicator indicates the status of it ; in case this indicator is off
(while input power is present), the surge protection is to be replaced
