I. INSTALLATION.
SAFETY MESSAGE TO INSTALLERS
NOTE
Installation, maintenance and disposal of this product must be carried out in accordance with
national codes and standards.
It is important to follow all instructions shipped with this product. This device is to be installed by a
trained electrician who is thoroughly familiar with and will follow all applicable national and local
codes in the country of use.
This device should be considered a part of the warning system and not the entire warning system.
The selection of the mounting location for the device, its controls and the routing of the wiring is to
be accomplished under the direction of the facilities engineer and the safety engineer. In addition,
listed below are some other important safety instructions and precautions you should follow:
• Read and understand all instructions before installing or operating this equipment.
• Do not connect this light to the system when power is on.
• After installation, ensure that all set screws are properly tightened.
• After installation, test the light system to ensure that it is operating properly.
• After testing is complete, provide a copy of this instruction sheet to all operating personnel.
• Establish a procedure to routinely check the light installation for integrity and proper operation.
Failure to follow all safety precautions and instructions may result in property damage, serious
injury, or death to you or others.
A. General.
The Model FB2PST is available for 12-24Vdc, 120Vac, 50/60 Hz and 230-240Vac, 50/60 Hz.
Model FB2PST-I is only available for 24Vdc.
B. Unpacking.
After unpacking the unit, examine it for damage that may have occurred in transit. If the
equipment has been damaged, do not attempt to install or operate it, file a claim immediately
with the carrier stating the extent of the damage. Carefully check all envelopes, shipping
labels and tags before removing or destroying them.
C. Model FB2PST and FB2PST-I.
The Model FB2PST strobe lights are designed for mounting on a flat horizontal or vertical
surface or on a 1/2" NPT threaded pipe. Mounting on a vertical surface with the lens
positioned upward can be accomplished using a separately purchased Federal Signal wall
(Model LWMB2) or corner (Model LCMB2) mounting bracket.
1. Pipe Mounting
The Model FB2PST can be mounted on 1/2 inch pipe. Mounting hardware and installation
details are left to the installer.
NOTE
To prevent the connection from loosening, tighten the fixture to a MINIMUM torque of 5 ft.-lbs.
(6.8N m) after threading it onto the pipe.

2. Surface Mounting
a. Using the gasket as a template, scribe the three mounting holes and the center hole for
surface mounting. Drill a 3/16" (4.8 mm) diameter hole at each of the three scribed
mounting marks. Drill or punch a 1" (25.4 mm) diameter hole at the center for the wires.
b. Set the light on gasket and attach to the mounting surface using the provided #8-32
screws.
c. Refer to paragraph E. for electrical connections.
D. Electrical Connections.
1. Models FB2PST 120 and 230-240 VAC.
Do not connect if supply wires are energized.
The FB2PST alternating current units are supplied with three leads (one black, one white,
and one green/yellow) for the AC units. Some models will have the following alternative
colors: brown instead of black, and blue instead of white. Connect the black (or brown) lead
to the phase side of the power source, the white (or blue) lead to the common (neutral) side
of the power source, and the green/yellow lead to earth ground.
NOTE
The 120 and 230-240 VAC Strobe units are designed to operate on both 50 and 60Hz electrical
power. Special modifications are NOT required for the two different AC line frequencies.
2. Model FB2PST (12-24VDC) and Model FB2PST-I (24VDC).
The Model FB2PST direct current unit is supplied with two leads (one red and one black).
Connect the red (+) lead to the positive power source terminal and the black (-) to the
negative power source terminal.
NOTE
Polarity MUST be observed for operation.
II.MAINTENANCE.
SAFETY MESSAGE TO MAINTENANCE PERSONNEL
Listed below are some important safety instructions and precautions you should follow:
• Read and understand all instructions before operating this system.
• Any maintenance to the light system must be done with the power turned off.
• Any maintenance to the light system must be performed by a trained electrician in accordance
with all applicable national and local codes and standards in the country of use.
• Never alter the unit in any manner.
• The nameplate, which may contain cautionary or other information of importance to maintenance personnel, should NOT be obscured in any way. Ensure that the name plate remains
readable when the housing’s exterior is painted.
Failure to follow all safety precautions and instructions may result in property damage, serious
injury, or death to you or others.
A. Flash Tube Replacement.
As strobe lights are used, the flash tubes begin to darken, causing the light output to decrease.
This darkening is characteristic of flash tubes. Darkening will begin near the base of the tube
and progress upward. Also, as flash tubes age, they may have a tendency to misfire (not fire
periodically).
-2-
After extended operation, occasionally check for flash tube degradation. Should the flash tube
misfire, have a noticeable decrease in light output, glow continuously or darken to a point
beyond that shown in figure 1—it should be replaced.
High voltages are present inside the light assembly. Wait at least 5 minutes after shutting off the
power before servicing this unit.
To replace the flash tube, proceed as follows:
1. Disconnect power.
2. Remove the screw located at the bottom of the dome
3. Grasp the top of the dome and push down while turning the dome counter-clockwise
approximately 3/4-inch.
4. Gently lift the dome away. Ensure the gasket between the dome and base is not lost.
5. Grasp the flash tube by its base and pull it out of the socket, using a gentle “rocking”
motion. Insert the new flash tube.
6. Before replacing dome, ensure that the gasket is properly seated on the housing base.
Place the dome over the base, aligning the recesses inside the dome lip with the four pins
on the base. Push down on the dome and turn clockwise until it locks in place (approximately 3/4-inch)
7. Replace the screw in the bottom of the dome.
8. Test the light for proper operation.
B. PC Board Replacement.
High voltages are present inside the light assembly. Wait at least 5 minutes after shutting off the
power before servicing this unit.
1. Disconnect the power.
2. Remove the remove the screw located at the bottom of the dome
3. Grasp the top of the dome and push down while turning the dome counter-clockwise
approximately 3/4-inch.
4. Gently lift the dome away. Ensure that the gasket between the dome and base is not lost.
5. Remove the flash tube as described in paragraph II.A.5. Flash Tube Replacement.
6. Remove the power connector(s) from the P.C. board. When replacing older board assemblies,
the power connectors need to be adjusted to match the new assemblies. Included with the
replacement board is a power lead adaptor. Since some strobes are polarity sensitive,
connect matching colored wires together.
7. Remove the 6-32 screws, which secure the circuit board to housing base. On older DC units,
the #4 phillips head screw securing the power transistor must also be removed. Remove the
old circuit board. Place the new circuit board in position. Secure the circuit board in
position by installing two 6-32 screws at opposite corners of the circuit board.
8. Install the flash tube as described in paragraph II.A.5. Flash Tube Replacement.

9. Before replacing dome, ensure that the gasket is properly seated on the die-cast base. Place
the dome over the base, aligning the recesses inside the dome lip with the four pins on the
base. Push down on the dome and turn clockwise until it locks in place (approximately 3/4inch).
10. Replace the screw in the bottom of the dome.
11. Reassemble the light and test for proper operation.
C. Service.
The Federal factory will service your equipment or provide technical assistance with any
problems that cannot be handled locally.
Any units returned to Federal Signal for service, inspection, or repair must be accompanied by
a Return Material Authorization. This R.M.A. can be obtained from the local Distributor or
