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 lead to
earth ground (if required). Use 18 AWG wire or larger.

MAINTENANCE
To prevent receiving an electrical shock, disconnect the fixture from the supplycircuit before open-
ing. 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 and standards in the country
of use.
•
Never alter the unit in any manner. The safety of the unit may be compromised if
additional openings or other alterations are made.
•
The nameplate, which may contain cautionary or other information of importance
to maintenance personnel, should NOT be obscured in any way. Ensure that the
nameplate remains readable when the housing's exterior is painted.
•
If the dome is damaged in any way, it MUST be replaced.
•
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.
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).
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 on page 17, 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.
