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 stand-alone 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.
The 24VDC and 240VAC LSH units produce 75dB @ 10' (85dB @ 1m); the 120VAC unit produces 77dB @ 10' (87dB @ 1m). Litestak is UL listed for indoor use and CSA Certified.
Ideal applications for Litestak audible/visual status indicators include assembly lines, conveyor systems, automated lines, instrument panels, workshops, etc.
Federal Signal's Piezoelectric Horn is an inexpensive way to add an audible signal to Litestak Status Indicators.
