Installation and Maintenance Instructions
There are three mounting options: Non-weatherproof mounting,
weatherproof mounting, and weatherproof panel mounting.

Non-Weatherproof 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.

Weatherproof Mounting

See Figure 5. For weatherproof mounting, use a Federal Signal
Model WB weatherproof box when a NEMA Type 4X or IEC
IP66 rating is required. The Model WB is gasketed and has
two 3/4" and one 1/2" tapped openings to accommodate 3/4"
and 1/2" conduit. When mounting the horn on the Model WB,
use the provided #8-32 x 1-5/8" screws. Torque the mounting
screws 12 in-lb to 16 in-lb (1.4 Nm to 1.8 Nm).
