6.0 Operation and Setup
Avlite’s I3 Obstruction Lighting Solution Kit consists of five components: A Control Unit
which provides power, day & night control and (optional) remote monitoring, a single
red/white omnidirectional, Combined Medium Intensity obstruction beacon (CMI), and three
LI Single Fixture red obstruction lights.
The top light fixture (CMI) is designed to comply with either ICAO MIOL Type A & B or
Type A & C requirements and the middle lights (LI) comply with ICAO LIOL Type A & B
requirements.
Both the CMI and LI Single Fixtures incorporate internal diagnostic checking and an alarm
contact for remote monitoring. The alarm relay is energized in normal operation and is
released if there is an LED or power fault.
An External Photocell allows the lights to automatically switch between day and night
mode. In night mode, the CMI is illuminated red and either flashes (For Type A & B) or
remains steady-burning (for Type A & C). The LI single fixtures operate as steady-burning
red lights. In day mode, the CMI flashes white while the LI Single Fixtures remain off. The
Photocell output can also be overridden for system testing and maintenance via the
Photocell Bypass Switch. (See section 6.1.3 for more information).
The Control Unit automatically evaluates the I-3 system for operation and performance
criteria while providing local and remote display of information and alarms; operators can
conveniently view the lights’ real time status from the web based Star2M™ portal (if option
purchased).

6.1.3 T3 Controller
The T3 Control Unit is an essential component of the I3 Obstruction Lighting Kit as it
provides power, control and monitoring of the light fixtures in the system.
For safety and security, the control enclosure comes with a safety interlock which prevents
access to the controller while the system is powered on.
The Controller is available in two input power configurations; a universal AC or DC and
comes with remote monitoring via Star2M with either GSM or Satcom telemetry types as
options.
By default, the control unit comes with 2 dry contacts for external monitoring of both the
CMI and LI single light fixtures which receive the associated alarm (i.e. Group 2 for the CMI
and Group 1 for the LI single fixture lights) in the event of a power or LED fault.
Note: External dry contact monitoring is unavailable if remote monitoring via GSM or
Satcom has been enabled
A Photocell Bypass Switch is provided with the Control Unit to override the Photocell output
for system testing and maintenance. It is factory-set to AUTO (auto day/night) mode.
To test the function of lights for day operation, turn the Photocell Bypass Switch to the Day
position. The CMI should flash white while the LI Single light fixtures remain off.
To test the function of lights for night operation, turn the Photocell Bypass Switch to the
Night position. The CMI should be illuminated red and should either flash (for CMI Type
A & B) or remain steady-burning (for CMI Type A & C). All LI Single Fixtures should be
illuminated red in the steady-burning configuration.
To return to the Auto mode, return the switch to the Auto position.
Note: Time delays are to be expected when changing modes. Allow up to 1 minute to
change between functions.

6.1.5 GPS Synchronisation
Avlite has utilised the latest advancements in GPS technology to develop an internal
synchronisation system that is incorporated into the lights. Using overhead satellites,
the CMI of multiple I3 Lighting Kits set to the same flash pattern are able to flash in
unison. No additional power supplies, aerials or control systems are required, and with
its microprocessor- based system, the GPS option is specifically designed to provide
maximum reliability and performance over a wide range of environmental conditions.
Operating Principle
Each light operates independently and requires no operator intervention. A minimum
of 4 satellites need to be in view for the built-in GPS receiver to collect time data. At
dusk, the light sensor will turn the light on. If time data is available, the CMI will come on
synchronised to every other CMI light with the same selected flash code. Synchronisation is
achieved using an internal algorithm based on the highly accurate time base and time data
received from the satellites. The satellite data is provided from a number of earth stations
using atomic clocks as the time base. Continuous self-checking ensures that the light will
continue to run in synchronisation.
Light Activation
At power-up the microprocessor checks that the internal GPS module is programmed
correctly and is able to provide valid time base and time data. Once outside with a clear
view of the sky, valid data should become available within 20 minutes.
Note: Lights will not synchronise if different flash codes are selected.
