Section 1 - Overview
The FTS 370i-2 IR (Infrared) LED Integrated FAA L-864 Flashing Red Beacon with Radar
Compatible Interface as shown in Figure 1-1, (hereafter referred to as the beacon) is pre-wired
with a power & alarm cable and operates from 120-240VAC 50/60 Hz. The only required
customer connection is the AC line; as the beacon incorporates an integrated controller which
flashes the beacon at night. The unit is equipped with an alarm contact and auxiliary control
input for connection to a radar system interface. The fail-safe design of the interface allows for
operation of the beacon if the radar system control wiring is interrupted. Also incorporated into
the controller is a GPS receiver and antenna, which allows synchronization to other beacons with
no additional wiring. The beacon consists of 24 high-performance LEDs that provide the FAA
required light output while consuming 99% less electrical power than an incandescent fixture.
The beacon incorporates 6 infrared LEDs. The addition of IR ensures visibility of the
obstruction to pilots aided by night vision goggles (NVG). The combination of standard Red
(620nm) LEDs and IR (850nm) LEDs ensures maximum visibility to pilots in all circumstances.
The FTS 370i-2 IR beacon also provide ICAO Medium-intensity, Type B Obstacle Light (Red)
compliance.
The beacon is designed for the lighting of wind turbines, towers, flare stacks, chimneys, offshore
oil platforms, petrochemical facilities and other obstructions to aerial navigation, as specified by
the FAA, FCC, ICAO and Transport Canada.
This manual provides guidance and recommendations for the installation, inspection, and testing
of the beacon assembly. Please read this document in its entirety before installing the beacon.

Section 2 – Installation – Mounting, Wiring, and Checkout
Warning
Read the warning on page ix now. Remove power from all wiring and circuitry before installing
or performing work on the beacon. It is the responsibility of the installer to comply with all
applicable electrical codes.
Important!
For proper operation and optimal protection from Lightning and EMI, ensure that the
base is electrically bonded to the site grounding system using 8 AWG wire minimum
connected to the supplied external ground lug.
Flash Technology recommends the installation of one or more lightning rods near the
beacon. The copper lightning rod(s) should be located approximately 18 inches away from
and extend a minimum of three feet above the height of the beacon.
Installation Procedure:
1. Mount the beacon (Section 2.1)
2. Wire the beacon power (Section 2.2)
3. Verify operation (Section 2.3)
4. Wire the beacon monitoring connections (Section 2.2)
5. Confirm monitoring status by disconnecting power to the beacon. This should create an alarm.
After all steps are completed successfully, the installation is complete.
2.1 Mounting the Beacon
Flash Technology recommends the installation of one or more lightning rods near the beacon.
The copper lightning rod(s) should be located approximately 18 inches away from and extend a
minimum of three feet above the height of the beacon.
The beacon should be positioned so that the light collector for the photodiode has an
unobstructed view of the polar sky. Also, it must not view direct or reflected artificial light. The
GPS antenna located on top of the beacon must have an unobstructed view of the sky for proper
reception and synchronization.
The beacon is mounted to the tower pedestal or optional mounting bracket1utilizing supplied
hardware. Four mounting holes are provided on the beacon base (Figure 2-1). These mounting
holes will align with most tower pedestals. The beacon should be installed level to maintain light
output in accordance with FAA/ICAO requirements.
1. An optional mounting bracket is available to accommodate various installation configurations
and to facilitate leveling the beacon. See Section 5.5 for ordering information.

2.2 Wiring the Beacon
The beacon is supplied with a 50-foot length of power & alarm cable pre-wired to the internal
electronics to facilitate installation (see Table 2-1). The only connections required are power
(120-240 VAC, 50/60 Hz) and ground. The ground wire must be connected for proper operation
and protection of the beacon.
Optional dry contact monitoring connections permit monitoring of beacon operation. The
contact is closed when the beacon is operating normally and no fault is detected.
The Auxiliary Control Input allows an external device, such as a radar system, to inhibit the
flashing of the beacon (see Table 2-2). The acceptable input voltage range for the Control Input
is 5 – 30 Volts AC/DC. The optional 10 conductor cable is required to utilize this feature.

2.3 Verifying Operation
Apply power to the beacon and verify operation as indicated by the beacon and Status Indicator
LEDs.
Note: See Section 3.1 for a description each Status Indicator LED,
2.3.1 Power up
When powered up, all indicator LEDs are turned on for 10 seconds providing easy verification of
operation. The beacon will begin flashing and will turn off after 40 seconds if the photodiode
detects sufficient light. Otherwise, the beacon will remain on until the ambient light rises to a
sufficient level.
2.3.2 Synchronization
For synchronization to occur, the GPS antenna (located on top of the beacon) must have an
unobstructed view of the sky. As much as 15 minutes may be required for the beacon to achieve
a GPS signal lock. Following power up, the Sync Alarm and Sync Status LEDs will turn off.
Once a GPS signal lock is achieved, the Sync Status LED will turn on. This is the normal
operating condition.
Note: After one hour of operation, the Sync Alarm will turn on if a GPS signal lock has not been
achieved. The alarm will turn off once a GPS signal is locked. Refer to Section 5 if the Sync Alarm
remains on for more than 15 minutes.

Section 4 - Beacon Operation
4.1 System Overview
The beacon wiring diagrams are shown in Figures 4-1 and 4-2. The standard five conductor
power & alarm cable, shown in figure 4-1, provides connection of the AC line (3 wires) and
alarm monitoring connections (2 wires). The optional ten-conductor cable, shown in Figure 4-2,
provides the same connections and adds connections for the auxiliary control input (2 wires).
The remaining 3 conductors and drain wire are connected to chassis ground.
The AC line may be 120-240VAC 50/60Hz. The dry contact alarm connections are closed when
the beacon is operating normally and no fault is detected. The voltage range for auxiliary control
input is 5 – 30 Volts AC/DC. The beacon flash will be inhibited when voltage within the
specified range is applied to the terminals labeled AUX + and AUX -.
The Controller Core PCB (370i-2 IR 2423800) senses ambient light focused by the light
collector onto the photodiodes and at night flashes the LED beacon. A GPS antenna and
integrated receiver permit synchronization to other beacons. The Controller Core PCB detects
alarm conditions including beacon failure, photodiode alarm, and synchronization fault. A clear
polycarbonate cover provides access to view the status and alarm LEDs to permit easy
determination of proper operation and fault diagnosis.
The LED Engine assembly contains high-performance LEDs, which illuminate when powered by
the Controller Core PCB. The complete assembly (370i-2 IR 1370480) is easily replaced when
field service is required.
The Power Supply (5150501) and the Surge Suppressors (11000016050) are located in the base
of the beacon. The power supply generates the proper DC current to the Controller Core PCB
when AC line voltage is applied at its input. The surge suppressors, wired in line with and
directly across the AC Line, provide protection from incoming lightning and transient voltage
induced surges.
