DIN Mount Models.
These models utilize a DIN mounting/connec-
tion installation. They are designed for installation on a
24mm tube/female DIN connector.
NOTE
If a user-supplied switch is used, it must have a
current capacity of at least 8-amperes.
1.
Loosen the wing nut on the base of the light
assembly.
2.
Slide the light assembly onto the 24mm
tube/female DIN connector. Ensure that the connector is
seated in the base of the light.
3.
Finger-tighten the wing nut until the base
is snug on the DIN connector.
4.
Install a user-supplied fuseholder in the
light’s positive lead and install a 8-ampere fuse in the
fuseholder.
IV. MAINTENANCE.
A.
General.
WARNING
Crazing (cracking) of domes will cause reduced
effectiveness of the light. Do not use cleaning
agents (which will cause crazing) such as strong
detergents, solvents, or petroleum products. If
crazing of dome does occur, reliability of light for
emergency signalling purposes may be reduced
until dome is replaced.
1.
The dome can be cleaned using a non-
abrasive, high quality, automotive paste wax and a soft
cloth.
2.
On magnetic mount lights, periodically
inspect the magnet for dirt and metal shavings. Clean
the magnet as necessary. Keep the area around the
magnetic mount light free of dirt and metal shavings.
3.
Apply a film of light grease to the gears
when necessary.
B.
Lamp Replacement.
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.
CAUTION
Service life of lamp will be shortened if glass
portion is touched. If glass has been handled,
clean carefully with a grease solvent.
1.
Rotate the reflector until the C-clip (located
at the base of the lamp) can be removed, and remove the
C-clip by sliding it away from the reflector.
2.
See figure 3. Note the lamp’s orientation
and replace the lamp with the straight edge of the
lamp’s base toward the reflector. Replace the 12V lamp
with Part No. 8440A265 and the 24V lamp with Part
No. 8444A151.
C.
Mechanism Removal (for servicing).
1.
Push and hold the dome release button
(located in the plastic base). Turn the dome counter-
clockwise and lift the dome off the base (see figure 1).
2.
Disconnect power to the light. Disconnect
the red and black leads in the light.
3.
See figure 1. Push and hold the mechanism
release tabs.
4.
Slide the mechanism over the release tabs
and lift the mechanism out of the base.
5.
After servicing, replace the mechanism by
performing the above steps in reverse order.
