The FB24STHI direct current units are provided with five leads; two red, two
black, and one green/yellow. To achieve electrical supervision, connect one red (+) lead to the
positive side of the incoming power source and the other red (+) lead to the outgoing power
source. Then connect one black (-) lead to the negative side of the incoming power source and
the other black (-) lead to the negative side of the outgoing power source. Connect the green/
yellow to earth ground.
III.
MAINTENANCE.
To prevent receiving an electrical shock, disconnect the fixture from the supply
circuit before opening. High voltages are present inside the light assembly. Wait at
least 5 minutes after disconnecting power before servicing this unit.
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 in the

After performing any maintenance, test the light system to ensure that it is
operating properly.
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. The darkening will begin near
the base of the tube and progress upward. In addition, as flash tubes age, they may have a
tendency to misfire (not fire periodically).
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 2 — 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.
