Piezoelectric Horn

Model LSH

The Litestak®LSH Horn is a piezoelectric unit that employs a
ceramic element which expands or bends when voltage is applied,
generating a single tone. The Model LSH can be used as a stand­alone audible device (with the LSB pipe/surface mount base or
LSBS surface mount base), or combined with the Federal Signal
Litestak light modules to create a combination audible/visual signal.

The LSH Horn is a modular unit which mounts directly onto the
top of any Litestak light or base (sound units must be positioned
at the top module of the status indicator). A black speaker grille
cover protects the horn. The volume can be adjusted by
removing the grille covers and turning the volume control below
the horn mechanism.
