Installation and Maintenance Instructions
Model 450E Electronic Horn
There are three mounting options: Non-weatherproof mounting,
weatherproof mounting, and weatherproof panel mounting.

See Figure 4. If weatherproof mounting is not required, mount
the horn on a 4" x 4" outlet box with the two supplied
#8-32 x 1-5/8" screws. Torque the mounting screws to a
maximum of 16 in-lb (1.8 Nm).
Use the two remaining 8-32 screws and Keps nuts to cover the
two unused holes in the horn grille.
