C. NFPA INSTALLATION.
MESSAGE TO NFPA INSTALLERS
For mounting, color configuration, and
mounting considerations, refer to the latest
edition of the NFPA standard for automotive
fire apparatus.
For Models ADL5202 and ADL5256, use figure 2
and table 3 as a guide (for mounting and wiring)
when installing this light assembly as part of an
NFPA certified system.
D. MAINTENANCE.
1.
Cleaning the Plastic Domes.
WARNING
Crazing (cracking) of domes will cause re-
duced effectiveness of light system. Do not
use cleaning agents (which will cause crazing)
such as strong detergents, solvents, or petro-
leum products. If crazing of domes does occur,
reliability of light for emergency purposes
may be reduced until domes are replaced.
Ordinary cleaning of the plastic domes can be
accomplished by using mild soap and a soft rag.
Should fine scratches or a haze appear on domes,
they can ordinarily be removed with a non-abrasive,
high quality, one-step, automotive paste cleaner/wax
and a soft cloth.
2.
Lamp Replacement.
CAUTION
Service life of lamp will be shortened if glass
portion is touched. If glass has been handled,
clean carefully with a grease solvent.

WARNING
A serious injury may result if lamp is touched
when hot. Always allow lamp to cool before
removing. Halogen lamps are pressurized and
if broken can result in flying glass. Always
wear gloves and eye protection when handling
the lamps.
To replace the halogen lamp, proceed as
follows (see figure 3):
CAUTION
Forced rotation of the light mechanism will
cause damage to the worm gear. ALWAYS
rotate the light mechanism by rotating the
motor shaft.
a.
Rotate the reflector until the lamp clip
(located at the base of the lamp) can be removed, and
remove the clip by sliding it away from the reflector.
b.
Note the lamp’s orientation and pull the
defective lamp and connector out of the socket.
CAUTION
When installing a new lamp, do not touch the
glass portion. If the glass has been touched,
shortened lamp life will result. If the glass
end has been handled, it should be carefully
cleaned with a grease solvent.
c.
Replace the defective lamp with a new
H-1 halogen lamp (Federal Part No. 8440A265A).
