Safety Warning
This equipment uses lethal voltages which can cause serious injury and/or death. Do not
attempt to service this equipment with line power applied. Only trained and qualified
personnel should install, maintain or troubleshoot this equipment.
The LED lamps used in this equipment produce brilliant flashes of light and infrared (IR)
radiation. Temporary or permanent eye damage may result from looking directly at the
LED flash head while it is operating.
Do not rely on interlock switches to remove lethal voltages from the system. Measure for
voltages using a voltmeter to ensure that power is off and has been completely removed.
Do not wear any jewelry. Gold and silver are excellent conductors of electricity.
This equipment emits near infrared radiation. Avoid direct eye exposure.

Introduction
Congratulations! You have purchased one of the most advanced red LED/Infrared
obstruction lights available today. This product is the result of many years of engineering
with extensive input from field service personnel.
Please take the time to read and familiarize yourself with this manual. It contains the
information necessary to install, test and troubleshoot the IFH-1900-0IR.
Product Description
The IFH-1900-0R is a medium intensity red LED lighting obstruction light as defined by
FAA Advisory Circular AC 150/5345-43 and Transport Canada's Canadian Aviation
Regulations (CAR) 621. This obstruction light meets or exceeds the specifications as
defined in the advisory circular and CAR when operated as specified. For more
information please refer to the FAA or Transport Canada websites.
www.faa.gov/airports/resources/advisory_circulars.
www.Canada.ca
This obstruction light is designed to be flashed at 30
flashes per minute (30 FPM) and 53% duty cycle by an
obstruction light controller which is not included. For a
complete red obstruction lighting system see part
number ILS-1900-0IR.
Theory of Operation
IFH-1900-0IR L-864(L) Series flash heads consist of one string of Red Light Emitting
Diodes (LEDs) and one string of Infrared Emitters. Infrared Emitters are used for
increased conspicuity with night vision systems. A microprocessor controlled current
source supplies power to the Red LED string and the Infrared Emitter string. The
microprocessor measures the current through each string as well as the voltage of each
string to determine if any malfunction requiring shut down exists. Upon detection of a
malfunction the microprocessor turns off both the LED and Infrared strings to enter a low
power mode allowing the ground-based controller to detect and report an alarm condition.

Installation
The following section describes how to install the IFH-1900-0IR Obstruction Light.
Additional drawings and installation instructions are included with the lighting system and
should be reviewed before installation begins.
Broadcast Tower Installations
Installations on AM, Hot AM and FM broadcast towers require additional installation steps
that are beyond the scope of this manual. Please request ITL Broadcast Tower
Recommended Practices (DOC-AMFM-MNL.pdf) via the contacts listed at end of this
manual.
Unpacking your IFH-1900-0IR
Please examine the shipping containers and their content thoroughly upon receipt and
report any potential shipping damage to the carrier.
Tools for Installation
The following tools are suggested for mounting of the ITL power supply and LED beacon.
 Digital multi-meter capable of reading 600VAC/DC (Fluke 177 or 179)
 Nut Drivers and Sockets
 #2 Phillips Screwdriver
 5/16 Flat Head screwdriver
 1/8 Flat Head screwdriver
 Crimp Tool
 Needle Nose Pliers
Quick Installation Guide
The quick start guide shows how to install the LED lighting system.
 Certain broadcast applications require special installation considerations due to the
presence of high RF fields. See ITL document DOC-AMFM-MNL.pdf for further
information.
 Mount IFH-1900-0IR flash head(s) using the hardware supplied. Level each IFH-
1900-0IR flash head using the procedure described in section Flash Head
Leveling. Ensure the metal flash head base makes electrical contact with the

IFH-1900-0IR

tower structure. Remove paint from the tower structure as necessary. The flash
head must be mounted in the upright position. Ground the flash head using the lug
provided on the flash head base and an AWG 6 or larger copper conductor.
 Connect LED flash head cable (CBL-TC14-03S) from the power supply cabinet to
the obstruction light controller following the procedure described in section Flash
Head Cable Termination in this manual. The flash head cable shield drain wires
must be grounded in the Flash Head and in each junction box.
 Connect LED flash head cable (CBL-TC14-03S) to the obstruction light controller
(see controller manual for details). The flash head cable shield drain wires must be
grounded in the controller.
 Apply power to the obstruction light controller.
 Assuming day time ambient light levels, allow a few minutes for the system to read
the photocell and set the operating mode to Day mode.
 Cover PEC and verify that the system switches from Day to Night mode
 Verify that there are no alarms while operating in Night mode.
 Verify that each IFH-1900-0IR flash head produces a red flash 2 seconds.
 In the IFH-1900-0IR flash head, press and hold button PB1 until a red and IR
alarm are indicated and the IFH-1900-0IR stops flashing. Verify that the
obstruction light controller reports an alarm condition. A short press of PB1 will
cause the IFH-1900-0IR to resume normal operation.
 Uncover PEC and verify that the systems switches back to Day mode
 Toggle the obstruction light controller manual mode switch from Day to Night and
observe that the unit’s operation follows the switch
 Move manual toggle switch back to ‘Auto’ position
 The IFH-1900-0IR must be mounted in the upright position.

IFH-1900-0IR Flash Head Leveling
The flash head must be leveled properly for correct vertical beam spread. The diagram
below details how use a compact “torpedo” level on two axes to ensure that the flash
head is mounted level. Use galvanized steel or stainless steel shims as necessary to
achieve level mounting of the flash head. Do not compromise grounding of the flash
head.
IFH-1900-0IR Flash Head Cable Termination
Use only ITL cable, part number CBL-TC14-03S, for connecting the flash head to the
controller. The cable contains three (3) color coded AWG14 conductors surrounded by a
foil shield and a bare drain wire. Connect each color coded conductor to the
corresponding terminal in the flash head as shown below. Secure all screw terminals
firmly. When terminating the flash head cable in the obstruction light controller and in the
flash head the drain wire must be grounded. Ground screws are provided in both the
flash head and the power supply for grounding the drain wire. The length of the drain
wire inside the power supply and flash head should be as short as possible.

IFH-1900-0IR Operation
The IFH-1900-0IR flash head does not require any configuration. DIP switch SW1 should
be left in the factory default positions. The IFH-1900-0IR is designed to be flashed at 30
flashes per minute (30 FPM) and 53% duty cycle by an obstruction light controller which
is not included.
IFH-1900-0IR Indicator Lights
The IFH-1900-0IR flash head contains several indicator lights that can be of assistance in
determining the cause of a failure. The indicator lights are located on the main control
board in the bottom of the flash head.
