Replacing The Flash Tube - Federal Signal 154XST Serie Instrucciones De Instalación Y Mantenimiento

EXPLOSION HAZARD—To maintain the vapor-tight enclosure,
do not damage the dome or threads while disassembling or
reassembling the unit. Lubricated threaded joints exposed
for long periods of time may attract small particles of dirt or
other foreign materials. Housing and cover joints should be
reassembled immediately, with all the threads fully engaged.
SHOCK HAZARD—Strobe systems generate high voltages.
Disconnect power from the strobe system and wait at least
5 minutes before opening the unit. Do not apply power to
the unit while the unit is open. Failure to follow this warning
could result in serious injury or death.
Establishing a regular maintenance and inspection schedule
extends the life of the Model 154XST and ensures safety. For
service, support, or replacement parts, see pages 18 through 19.

Replacing the Flash Tube

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 4, it should be replaced.
HANDLE STROBE LAMPS CAREFULLY—Strobe lamps get
hot enough to burn you. Always allow these lamps to cool
before handling them. Strobe lamps are also pressurized
and, if broken, can result in flying glass. Failure to follow
this warning may result in personal injury.
