4. Connect the signaling circuit field wires to the terminals
(Figures 2 and 3).Polarity must be observed for units operating
on 24 VDC.
5. Mount horn assembly on the mounting plate (Figure 1).
a. The inside of the top of the grille has hinges that pass
through cutouts and engage with tabs on the mounting
plate. With the bottom of the grille lifted out slightly,
place the grille over the mounting plate so that the hinges
of the grille are in the mounting cutouts.
b. Properly seat the grille by pressing the bottom in.
c. Fasten the bottom of the grille to the mounting plate by
installing the captive combination drive screw.
6. Apply power and activate the horn unit to verify that it is
operating properly.
Maintenance
CAUTION
Should the unit fail to operate properly, do not attempt
