4. The horn housing is weatherproof but water can enter the conduit hole if not prop-
erly sealed. When rigid conduit is used, the conduit should not be clamped closer
than three feet from the horn to prevent damping the vibrations of the horn. When
installing with flexible cable, be sure the conduit hole is DOWN.
If this is not possible, use a gland type fitting or seal with a caulking compound.
In 250VDC applications where dusty or damp conditions exist, the horn's conduit en-
trance must be sealed with a CG type waterproof cable connector and flexible cable.
5. Rags or other objects should not be put into projector to muffle the sound output
as any interference with the air flow in the projector will cause electrical damage
to the horn mechanism.
