a horizontal bell and vertical diaphragm head so
that moisture drains away from diaphragm seat. Bells
are mathematically calculated to amplify sound while closely
retaining its fundamental frequency and natural
harmonics.

Three KM air horns positioned at 120 degree angles to give all
round 360
degree coverage.

valve to allow manual over-ride in the event of a power
