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.

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 mainte-

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).
