Personnel Hazard Warning
Dangerous Voltages
Dangerous line voltages reside in certain locations in this equipment. Also, this equipment
may generate dangerous voltages. Although FTCA has incorporated every practical safety
precaution, exercise extreme caution at all times when you expose circuits and components,
and when you operate, maintain, or service this equipment.
Avoid Touching Live Circuits
Avoid touching any component or any part of the circuitry while the equipment is operating.
Do not change components or make adjustments inside the equipment with power on.
Dangerous Voltages Can Persist with Power Disconnected
Under certain conditions, dangerous voltages can be present because capacitors can retain
charges even after the power has been disconnected.
Protect yourself — always turn off the input (primary) power and wait for one minute for
storage capacitors to drain their charge. Then, check between the red and blue wires on the
flashhead terminal block with a voltmeter for any residual charge before touching any circuit
element or component.
Do Not Depend on Interlocks
Never depend on interlocks alone to remove unsafe voltages. Always check circuits with a
voltmeter. Under no circumstances remove or alter any safety interlock switch.

Section 1 – Introduction
and Operation
Environmental
Complies with FAA specifications in
AC 150/5345-43.
System
Each single FTB 324-2 System consists of
an FH 324-3 Flashhead, a PC 324-2 Power
Converter, a PEC 510 Photocell, and a
connecting cable from the power converter
to the flashhead.
The power converter supplies the
controlling circuitry to convert main AC
power to the required voltages for internal
operation and the discharge energy for the
flashhead. It also controls the flash rate.
The photocell senses changes in lighting
conditions from day to night and from
night to day thus signaling the power
converter to change its operation
appropriately. Also, a manual intensity
switch can override the photocell if
required.
NOTE
The Flashhead supplied with an FTB
324-2 System is an FH 324-3. If an older
flashhead is used, please call Flash
Technology for upgrades. See Table 4-3
for Retrofit Kits and Safety Support Tool.

In daylight, lights flash white at a rate of
40 flashes per minute (FPM) at an
intensity of 20,000 candelas. At night the
light flashes red at a rate of 20 FPM at an
intensity of 2,000 candelas.
Obstructions over 350 feet above ground
level require several interconnected PC
324 power converters (typically three)
operating the corresponding number of
flashheads. A master/slave control line
(two-wire) at terminals TB1-4 and TB1-5
at the front panel interconnects the units.
A sync pulse on the line flashes all the
lights in unison and at the same rate.

Photocell
The photocell changes resistance as ambient light changes from day to night or from night to
day. The Timing and Trigger Board (PCB1) in the master power converter then converts the
changes into the necessary circuit operation to flash the lights at the appropriate intensity for
day or night operation.
FTB 324-2 Revision 8 – 2-12-2010 3
PCB1 Timing and Trigger Board
PCB1 controls and monitors the operation of the PC 324. Status indicators and setup options

Board Configuration
the switch set to ON for this feature to be
used. The default (OFF – Isolate) prevents
slave units from causing the system to go
to white back up if a red failure occurs on
the slave. Generally, a system should only
go to white back up if the top (master
beacon) fails in red night mode.
The 2903800 board is programmed from
the manufacturer for operation in the PC
324. The board will be clearly marked in
the area shown in Figure 1-2.

Setting switch #1 to ON allows a red
alarm to be sent to other units over the
master/slave sync. This feature is used to
allow a slave beacon to send the rest of the
system into white backup when a failure
occurs in red night mode. The Master
beacon will read the alarm and send all
beacons into white backup. This is useful
for stack systems that have all beacons at
the same height and any failing beacon
should cause the system to go to white
backup. All units in the system must have
RS-485 Communication
RS-485 is used to communicate with the
FTM-5000 or FTW-17X for monitoring of
multiple beacon systems. The connections
are available on J8 in the lower right
corner. The pin assignments are shown
below:
When all switches are OFF, the RS-485 is
disabled. Once addressed, modem and
RS-232 communication will be disabled
and the RS-485 will become active. Table

Section 2 - Mounting, and
Installation
Unpacking
Inspect shipping cartons for signs of
damage before opening them. Check
package contents against the packing list
and inspect each item for visible damage.
Report damage claims promptly to the
freight handler.
Tools
Although no special tools are necessary,
Flash Technology suggests the following
hand tools for installation and
maintenance:
• 9 or 12 inch, flat blade #2 screwdriver
• #2 Phillips® head screwdriver
• Medium slip joint pliers
• Set of combination wrenches
• Long-nose pliers
• Assorted nut driver handles: 1/4”,
5/16”, 3/8” recommended
• Analog volt-ohm meter
• Multi-purpose crimp tool
Flashhead
Pivot the lens open by disengaging two
quick-release latches. Two lanyard cables
secure the lens. The flashhead normally
contains no interlock. Disconnect primary
power to the power converter before you
open the flashhead. Wait one minute for
storage capacitors to drain down. Open the
flashhead and use a voltmeter to check that
no voltage potential exists between the red
and the blue wires on the ceramic terminal
posts.
Mounting
Power Converter
Mounting and outline dimensions for the
power converter are shown in Figure 2-1.
Flash Technology does not furnish
mounting hardware unless ordered as part
of an installation kit. Use the following
guidelines for mounting the power
converter:
Ensure that adequate space exists around
the equipment for access during
installation, maintenance and servicing.
Allow space for air flow around the power
converter.
• Safety Support Tool (P/N 1905333)
Access
You must use a bonding strap on a bolt
through the power converter case leg.
Connect the strap to the site grounding
system.
WARNING
Before proceeding, read the warning on
Page iii. Disconnect the primary power
before opening enclosures.
Power Converter
The base of the power converter has
mounting feet. The cover lifts off for
unrestricted access to the interior. Release
the latches that secure the cover to remove
it for internal access.
FTB 324-2 Revision 8 – 2-12-2010 9
Flashhead
Mounting and outline dimensions for the
flashhead are shown in Figure 2-2. The
flashhead must be protected from lightning
strikes. The flashhead may be mounted to
painted or unpainted surfaces. One of the
mounting holes in the base of the
flashhead contains a built-in electrical
ground connection. Use the following
guidelines for mounting the flashhead:
Use a lightning rod extended above the
flashhead to protect it when it is mounted
at the uppermost part of the structure.
Avoid locating a lightning rod where it
would prevent tilting the lens open or
interfere with access by maintenance or
service personnel.
You must use a bonding strap with a
flashhead mounting bolt when mounting
the flashhead to the structure, using the
mounting bolt to fasten the strap to the leg
that contains the ground connection.
Flashhead Leveling
The flashheads must be level for correct
vertical beam alignment. Two leveling
vials—aligned with the mounting feet—
are permanently attached to the flashhead
assembly. Typically, the mounting surface
for the flashhead is level and no
adjustments are required. When the
flashhead is level, bubbles in both leveling
vials are centered. For leveling, use the
following guidelines:
If adjustment is necessary, raise the
appropriate mounting foot with shims or
washers. Raising one foot by 1/16 inch
(1.6 mm) tilts the beam about 1/2 degree.
Take extreme care to ensure that all four
feet rest snugly against a firm mounting
surface before tightening the mounting
bolts. Failure to do so could result in
serious damage to the base when you
tighten the bolts.
Photocell
Mounting and outline dimensions for the
photocell are shown in Figure 2-3. The
photocell uses a male 1/2” NPT for
mounting. Use the following guidelines to
mount the photocell:
Locate the photocell where it has an
unobstructed view of the polar sky.
It must not view direct or reflected
artificial light.
The photocell may be supported directly
by electrical conduit.
Ensure that the installation is watertight.
Installation
This manual may not contain all the
information about installation wiring
required for your installation.
NOTE
If installation drawings prepared
specifically for your site disagree with
information provided in this manual, the
site installation drawings should take
precedence. Consult any site-specific
installation wiring diagram supplied with
your equipment.
Flash Technology wiring diagrams
define only minimum requirements
recommended for satisfactory
equipment operation. It is the
responsibility of the installer to comply
with all applicable electrical codes.
You can find conduit and other
distribution wiring details on electrical
installation diagrams provided by Flash
Technology or others. Installation
instructions concerning red light marker
fixtures are not part of this manual.
All communication wiring should have an
insulation rating of 300 volts minimum.
All power wiring should have an
insulation rating of 600 volts. You must
size power service wiring to satisfy the
load demand of the red light system (if
present) and the power converters. Read
the notes on the installation wiring
diagrams supplied both in this manual and
with the equipment. See Figure 2-8 for
information about wiring alarm
connections to the main panel of the power
converter.
Power Converter Wiring
Consult the installation wiring drawings.
For service wiring, consider the voltage,
length of the wire run, and the total load
(number of lights). Assume a load of 175
10 Revision 8 – 2-12-2010 FTB 324-2
volt-amperes per light, and do not permit
the line voltage to drop by more than 5%
due to wire resistance. Assume a load of
175 volt-amperes per light to determine
the slow-acting fuse ratings at the power
distribution panel. Use a value of 250 voltamperes per light to determine fast-acting
fuse ratings at the power distribution panel
and to select a system feeder transformer
(if used).
In multiple-unit systems, the master unit
and slave units communicate over the
“master/slave” interconnect wiring. To
insure proper communication between all
interconnected units, the power converters
must be on the same electrical phase.
Also, the “master/slave” interconnect
wires must be twisted together at a
minimum rate of 6 twists per foot. The
recommended minimum size for control
and signal conductors is #16 AWG.
Flashhead Wiring
The power converter and flashhead are
interconnected by the flashhead cable.
When Flash Technology Part Number
6340, or equivalent cable, is used, the two
may be separated by a distance up to 600
feet. Consult the factory when a greater
separation is necessary. The cable between
the power converter and flashhead requires
five conductors with 600 volts (minimum)
insulation. Two of the conductors must be
#10 AWG. The other three may be #14
AWG (minimum; for mechanical strength)
if you are cabling together individual
wires.
To ensure long-term equipment reliability,
use continuous wiring between the power
converters and their flashheads without
intervening junctions or splices.
Securing the Cable
Flash Technology recommends the
following method for securing the
flashhead cable to a skeletal structure:
1. Run the cable along one of the tower
legs and wrap two full turns of twoinch Scotchrap™ #50 tape, or the
equivalent, around the cable and tower
leg at regular intervals of about 5 feet
(1.5 meters).
2. Wrap three full turns of one-inch
Scotchrap Filament #890 tape, or the
equivalent, over the Scotchrap #50
tape.
3. Wrap four full turns of two-inch
Scotchrap #50 tape, or the equivalent,
over the Scotchrap Filament #890 tape.
4. Perform steps 1 through 4 also directly
above and below any tower leg flanges
that the cable may cross.
Photocell Wiring
The photocell is supplied with a pigtail for
connection to wires that connect to the
power converter. It is connected to the
main panel of the power converter. It may
be located any practical distance from the
power converter. The recommended
minimum wire gauge is #16 AWG.
The photocell terminals on the slave
power converters must be jumpered from
TB1-1 to TB1-2. (An alternative jumper
may be installed on PCB1 J18-1 to J18-2.)
Also, the master unit (to which the
photocell is directly connected) must be
connected to the top flashhead.
Installation Checklist
Complete the following steps before
applying power to the lights.
1. Inspect all equipment for damage.
2. Verify the received equipment against
the packing list to ensure
completeness.
3. Power Converter Mounting. Position
and mount each unit correctly,
allowing adequate clearance for
FTB 324-2 Revision 8 – 2-12-2010 11
opening the covers. Use the following
checks:
on all units, and TB1-5 is similarly
connected.
1. Ensure that the case is mounted
upright, is water tight, and
grounded to the site grounding
system.
2. Check hardware to ensure that all
mounting hardware is tight.
3. Ensure that only the bottom of the
case has drain holes and that they
are clear.
4. Ensure that no holes are punched
or drilled on the top surface of the
case.
5. Ensure that air can flow around the
case.
6. Mount the power converter away
from radio frequency interference
(RFI).
4. Power Converter Wiring. Examine the
installation drawings and use the
following checks:
1. Check for proper incoming service
voltage.
5. Alarm Wiring.
1. If external alarm detection circuit
responds to closed contacts, ensure
that they are wired to the contacts
on TB1 that close on alarm.
2. If external alarm detection circuit
responds to open contacts, ensure
that they are wired to the contacts
on TB1 that open on alarm.
3. Alarm wiring should be lightning
and RFI protected: shielded,
grounded shield, and in a conduit.
4. If a specific alarm is ganged
together from all power converters
as one, ensure that the wiring
follows local installation
instructions.
6. Flashhead Mounting.
1. Ensure that the flashhead lens can
be opened without striking other
objects.
2. Level and aim the flashhead.
2. Wire each unit according to the
instructions.
3. In multiple installations of three
systems, all three power converters
should be on the same breaker.
4. Check all electrical connections for
tightness.
5. Check all terminal strip
connections for tightness.
6. Ground the power converter.
7. Wires at master/slave interconnect
terminals should be daisy-chained
as a twisted pair between the
master power converter and the
slave units. The rate of twist is 6
per foot minimum. If a shielded
cable is used, ground the shield.
For example, ensure that TB1-4 is
connected to all TB1-4 connections
7. Flashhead Wiring.
1. Protect the top flashhead against
lightning strikes.
2. Ground the flashhead.
3. Check the wiring of the flashhead
cable to the flashhead.
4. Secure the flashhead cable to the
tower. Support and tape the
flashhead cable to prevent its
movement by the wind.
8. Photocell.
1. Locate photocell where it views
unobstructed polar sky with no
direct or reflected artificial lighting
striking it.
2. Mount the photocell vertically to
prevent water from entering the
12 Revision 8 – 2-12-2010 FTB 324-2
unit. Ensure watertight
connections.
3. Connect the photocell to the master
power converter.
After completing all the steps listed above,
turn on the power and perform an
operational checkout from procedures in
Section 3 of this manual.

Section 3 - Maintenance
and Troubleshooting
Safety
WARNING
STOP: Before proceeding read the
warning on Page iii.
Work safely, as follows:
it gently with a soft cloth or paper
towel.
7. Clean the inside surface of the lens
with a Flash Technology approved
professional plastic cleaner such as
Meguiar’s Mirror Glaze® Clear Plastic
Cleaner. Wipe the lens with
cheesecloth only. Do not use regular
cloth or paper towels.
1. Remove rings and watches before
opening the equipment.
2. Shut off the equipment.
3. Remove the component or connect the
test instruments.
4. Replace the component.
5. Turn on the power and test the system.
6. Turn off the power and disconnect the
test equipment.
Preventive Maintenance
Carry out the following inspection and
cleaning procedures at least once a year:
1. Verify that moisture has not
accidentally entered the equipment
through gaskets or seals, or collected
inside as condensation.
2. Verify that all drain holes are clear.
3. Check terminal blocks and relays for
corrosion or arcing. Clean or replace
any component that shows evidence of
high-voltage damage.
4. Check flashtube connections for signs
of pitting or arcing. Verify that anode
and cathode connections are firmly
tightened.
5. Check all electrical connections for
tightness and verify the absence of
corrosion or electrical arcing.
6. Clean the outside surface of the lens
with liquid detergent and water. Wipe
Storage
Store equipment indoors when not in use.
Circuit board, when not installed in the
equipment, should be kept in antistatic
bags or containers.
Diagnostic Testing
The only effective way to check out
interconnected lights is to disconnect the
master/slave interconnect wire that is
connected between power converters and
check the power converters as single units,
as described in Master Unit.
Sync Signal Evaluation
Refer to Figure 2-5. Note that, for each
power converter, the master/slave
interconnect line and its return line are
connected to TB1-4 and TB1-5
respectively. All units place a pulse on the
line, which causes the power converters to
flash all the lights at the same time. This
pulse is the synchronization pulse. PCB1
in each power converter generates a sync
pulse. The first sync pulse to be placed on
the line synchronizes the remaining lights.
The width of the sync pulse controls the
mode of operation.
In the event of a top-most red light failure
at night, the power converter places a
back-up signal on the line that causes all
connected units to flash the white lights at
the correct night intensity.
FTB 324-2 Revision 8 – 2-12-2010 23
The sync signal is a pulse and difficult to
evaluate with a meter. You can detect the
sync pulse as an instantaneous movement
of the meter indicator. A digital meter with
a max-min function may capture part of
the pulse. This is generally a sufficient
indication of a pulse being present. (A
24V pulse of 16 ms. width might read 12V
on a 100 ms. capture time of max-min
function.)
RFI Problems
The presence of radio frequency
interference (RFI) can burn out
components, cause a light to flash
intermittently, at the wrong rate, or at the
wrong intensity. RFI can enter the light by
any wire to or from the unit. The circuits
reject or bypass RFI, but Flash
Technology cannot guarantee complete
immunity beforehand. After installation,
you may find it necessary to add external
filters or use other methods to reduce RFI
entering the equipment. To minimize
interference, ensure proper installation in
accordance with AC 70-7460, Appendix 1,
Figure 2.
Component Testing
The following procedures describe how to
check most of the unit's major electrical
components. Always make resistance
measurements with the primary power
turned off. However, you must make
voltage measurements with power applied.
Thus, for your safety, carry out all
preliminary steps such as connecting test
leads or circuit jumpers, or disconnecting
existing circuit connections with the power
off.
Capacitors
Evaluate the condition of a capacitor with
an analog volt-ohmmeter operating in the
resistance mode. The following method
assumes an instrument with a X100
resistance scale.
Place the meter leads across the terminals
of an isolated (no electrical connections to
other circuits) and fully discharged
capacitor. Observe the subsequent needle
movement.
If the capacitor is functional, the needle
initially indicates zero ohms, but soon
begins to rise to higher indicated values. A
capacitor that is disconnected from other
circuitry is defective if it does not exhibit
this behavior. The length of time it takes
the needle to reach the 1-megohm reading
(about 65% full-scale) is a measure of the
capacitance. For example, the time is
about 5 seconds for a 10-mfd. capacitor, or
10 seconds for a 20-mfd. capacitor, and so
forth.
Manually discharge the capacitor before
repeating this measurement. This test may
not detect a malfunction that occurs only
at high voltage.
A bank of capacitors connected in parallel
may be checked as a single unit. If the test
indicates a short circuit, the individual
capacitors have to be disconnected and
checked separately. A shorted capacitor is
indicated if the resistance does not rise
above zero after several seconds of
measurement.
Wiring and Cabling
Wires or cables that move repeatedly will
ultimately break. Ensure that all cables
(the flashhead cable in particular) are
securely fastened at short intervals to the
structure or other supports.
Inspection
Closely inspect the units and check the
connections against the installation
instructions. Also, a close inspection may
reveal insulation breakdown, an
overheated component, corrosion, loose
connections, faulty relays, incorrect
hookup, and so forth.
24 Revision 8 – 2-12-2010 FTB 324-2
Power Converter
Burst Choke (L1)
Measure the resistance of L1 from TB3-5
to ceramic post E4 (at burst resistor R2).
Its resistance should be approximately 7
ohms.
Relays (K2, K3)
A malfunctioning relay may have faulty
contacts, a sticky mechanism, or a
defective coil. You may determine the first
two possibilities by inspection and
manually exercising the armature. You can
confirm a defective coil by measuring the
resistance. To measure the resistance of
relay coils, first remove the wires from
one of the connections to the coil terminals
on the relay.
The resistance across the coil of the K2
Mode Relay or the K3 Discharge Relay
should measure approximately 290 ohms.
Timing and Trigger Board (PCB1)
Replace this circuit board with one known
to be in good condition.
HV Rectifier Board (PCB2)
Replace this circuit board with one known
to be in good condition.
Sense Board (PCB4)
Replace this circuit board with one known
to be in good condition.
Discharge Resistor (R1)
The resistance of R1 between ceramic
posts E1 and E2 should be 35,000 ohms.
Burst Resistor (R2)
The resistance of R2 between posts E3 and
E4 should be 500 ohms.
Power Transformer (T1)
To test this transformer, first remove the
PCB1 and the HV rectifier board (PCB2).
Apply power to the unit and measure
secondary winding voltages at the
terminals indicated in Table 3-1.

value, check the C4 Tuning Capacitor.
Flashhead
Flashtube (FT101)
Visually inspect the flashtube for broken
electrodes, cracked glass, and the solder
connections of the pins. A darkened
envelope does not necessarily mean the
light output would be unacceptable.
Before concluding that a faulty flashtube
is responsible for an inadequate flash, first
rule out other possible causes such as
weak or absent discharge voltage or
triggering pulses.
Trigger Transformer (T101)
The measured resistance of the secondary
winding (potted assembly) should be
approximately 150 ohms. Check the ferrite
core for cracks. Check the mounting
screws for tightness.
FTB 324-2 Revision 8 – 2-12-2010 25
Trigger Coupling Transformer
(T102)
The coupling transformer should not have
open windings. An ohmmeter will indicate
a shorted winding because of the wire size.
Check with an ohmmeter at the wire
terminals.
Photocell Testing
Use the following procedure:
1. First, disconnect the photocell. The
system should go to night operation
after approximately one minute.
2. If multiple beacon system, disconnect
the master/slave interconnect line on
each power converter.
3. Operate the manual intensity control
switch on each power converter in
turn.
4. If each power converter operates
correctly with the manual intensity
control switch, troubleshoot the
photocell wiring or the circuits in the
erroneously operating power
converter.
5. Reconnect all wires.
During daylight, completely block light
from entering the photocell. If the system
does not enter night mode after a few
minutes, replace the photocell. At night,
shine a light on the photocell, if the system
does not enter day mode after a few
minutes, replace the photocell.
Component Removal and
Replacement
A power converter component location
diagram is provided in Figure 4-1. A
flashhead component location diagram is
provided in Figure 4-2. A flashhead
electrical wiring diagram is provided in
Figure 2-9. A power converter internal
wiring diagram is provided in Figure 2-6.
Note the location and color of all wires
that you disconnect. When you replace the
wiring after you replace the components,
ensure that the wiring agrees with Figure
2-6.
The general procedure for removing
components follows:
1. Obtain access to the component in
question.
• Disconnect completely or partially
the wiring to components first that
prevent clear access.
2. Completely remove or relocate these
components.
3. Disconnect the wiring to the
component that you want to replace.
4. Remove this component.
5. Replace everything in the reverse
order: first the component, then the
wiring. In some cases, you may have
to place some wires on the component
before you fasten it in place, then
replace the remaining wires.
Most components are relatively easy to
access for removal. Only those that are
more difficult are described.
Power Converter Components
Capacitors
Before removing or replacing a capacitor
always ensure it is discharged by checking
with a voltmeter directly across the
terminals. Discharge a capacitor by
placing a resistance (25 watts/10,000 ohms
or greater) between its terminals. Direct
shorting may damage the capacitor, and
connecting the terminals to the equipment
chassis may fail to discharge it.
Remove the fuse for this procedure to
prevent application of power if the
interlock switch is accidently pressed.
26 Revision 8 – 2-12-2010 FTB 324-2
Removal
1. Disconnect the wires leading to
capacitors.
2. Remove the hold-down screws.
3. Lift the capacitors from their receiving
holes.
Replacement
1. Reverse the removal procedure.
2. Verify that wiring is in accordance
with the wiring diagram in Figure 2-6.
Wires must be replaced exactly as
removed. In some instances, a quickconnect wire terminal does not seat
properly if it is not placed on the
terminal cluster exactly as it was
before removal. This occurs by
interference between the insulation on
the wire terminal and the insulation
surrounding their terminal cluster on
the capacitor. Flash Technology
recommends that you lightly squeeze
the quick-connect wire terminals with
pliers before reinstalling them over the
capacitor terminal blades.
Input Power Module

terminal to the left of TB4. This screw
fastens the module to the component
bracket.
4. Carefully slide the module to the right
and lift it out. Ensure that connectors
are not bent while doing so.
5. Remove any additional connections
necessary to remove the module.
Replacement
1. Reverse the removal procedure.
2. Verify that wiring agrees with Figure
2-6 and restore the wire routing to its
original state.

Manual Override: Fixed
Intensities
You may manually override automatic
intensity control (as when the manual
intensity override switch S2 is set to
AUTO), but only if no synchronization
line connects to other lights. Remove any
wire from external circuitry attached to the
master/slave interconnect terminals.
Manual control is intended for temporary
purposes (testing) only. Selecting Day or
Night operation with the manual override
switch activates an eight hour timer.
Automatic intensity control will resume
after eight continuous hours of operation
in the manual override position (Day or
Night).
• Note that the white light is flashing
at the daytime high-intensity.
2. Check Normal Nighttime Operation:
Place an opaque (blocks all light)
cover over the photocell and verify
that the red night responses at each
power converter in the system are the
same as those shown in Table 3-2 for
Nighttime operation.
NOTE
A minute may pass before the photocell
responds to the darkened condition
after power is applied.
• Note that the strobe is flashing at
the red nighttime intensity.
Daytime
Switch the Intensity Control Switch (S2)
to DAY
Night
Switch the Intensity Control Switch (S2)
to NIGHT.
PCB1 Indicator Lamps
See Section 1 for a description of LED
indicators on the PCB1 board for system
checkout.
Standard System
The following procedures check normal
operation.
1. Check Normal Daytime Operation:
Apply power to the system (pull the
plunger of the interlock switch or
switches outward to the service
position). Ensure that the manual
intensity override switch or switches
are set to AUTO and verify that the
daytime responses at each power
converter in the system are the same as
those shown in Table 3-2 for Daytime
operation.
Remove the cover from the photocell
and allow the unit to return to day
operation.
3. Check Alarm Sensing: Remove
primary power and temporarily
disconnect the black wire on TB2-4
and the violet wire on TB2-6. Apply
primary power and verify the
following:
• The white strobe does not flash.
• The WHT ALM LED (I8) is lit
after three missed flashes.
• The DAY ERR LED (I7) is lit.
• The alarm circuit operates
according to installation
requirements.
Cover the photocell as described in
Step 2 and verify the following:
• The red strobe does not flash.
• The RED ALM LED (I13) is lit
after three missed flashes.
• The NITE ERR LED (I15) is lit.
• The WHT ALM LED (I8) is lit
after three missed flashes.
FTB 324-2 Revision 8 – 2-12-2010 31
4. Restore the Equipment After
Checking: Replace all disconnected
wires. Remove the cover that you
placed on the photocell. Ensure that
the manual intensity override switch is
in the AUTO position.
5. If Any Responses are Not Normal:
If any of the responses above are not
exactly as described, proceed to
Troubleshooting.
Troubleshooting
Careful observation of operation often
leads directly to a symptom cause.
System-level problems affect all lights in a
multiple-light system in the same way.
Unit-level problems originate in a single
light. However, some unit-level
malfunctions can affect the entire multilight system. Use Table 3-3 for
troubleshooting a single unit and Table 3-4
for the system.
When you trace a problem to a specific
component, see Component Testing and
Component Removal and Replacement for
further assistance.
Master Unit
A stand-alone unit is a single FTB 324. A
master unit is similar to a stand-alone unit,
except that it is the controlling unit in a
multiple-light system. A master unit has
the photocell connected and, in a multiplelight system, is the controlling unit with
synchronization wires connected at the
master/slave interconnect terminals at
TB1-4 and TB1-5.
1. Temporarily disconnect the black
master/slave interconnect wire at TB1-
4.
2. Temporarily set the manual intensity
override switch S2 to DAY.
3. Verify the Daytime responses are the
same as those in Table 3-2.
4. Verify that the strobe is operating at
daytime intensity (high intensity).
5. Check the synchronization signal at the
black TB1-4 master/slave interconnect
terminal with a voltmeter as in Sync
Signal Evaluation. Use the intensity
control switch to step the unit from one
intensity to the other, or cover and
uncover the photocell. If the
synchronization signal is absent,
replace PCB1. A signal response could
indicate a slave unit problem or RFI
(see Slave Unit, and RFI Problems).
6. Reconnect the black master/slave
interconnect wire.
7. Place the manual intensity override
switch in the AUTO position.
Slave Unit
A slave unit receives intensity information
from a master unit over the master/slave
interconnect wires at TB1.
1. Temporarily disconnect the black
master/slave interconnect wire at TB1-
4. The unit will go into day operation.
2. Verify the Daytime responses are the
same as those in Table 3-2.
3. Check the synchronization signal at the
black master/slave interconnect
terminal with a voltmeter. The sync
pulse must be present as described in
Sync Signal Evaluation. Check wiring
if sync is not present.
4. Select NIGHT at the manual intensity
override switch. The unit will go into
night mode with the strobe flashing at
night intensity (low intensity).
5. Check the signal on the master/slave
interconnect wire at TB1-4 with a
voltmeter, as described in Sync Signal
Evaluation. An absent pulse requires
checking the system for RFI (see RFI
Problems) and for another
32 Revision 8 – 2-12-2010 FTB 324-2
malfunctioning unit connected to the
master/slave interconnect wire.
6. Reconnect the master/slave
interconnect wire to TB1-4.
7. Place the manual intensity override
switch in the AUTO position.
