HPG-370GA
GENERAL DESCRIPTION
Atlas Sound siren loudspeaker Model HPG-370GA is a reflex-type
loudspeaker with a rectangular molded bell. It is rated at 100 watts
RMS in electronic siren use.
Unit contains the patented Atlas Sound SD-370A compression driver
(U.S. Patent #7,760,501) complete with a non-fatiguing, self-aligning
sound chamber assembly. These drivers have earned acceptance as
the quality and performance standard for 100-watt electronic signal
systems in police, fire, ambulance, and utility vehicles throughout the
world.
A patented, heavy-duty, one piece steel mounting bracket (U.S. patent
#394,660) permits full-axis orientation of the loudspeaker for preferred
sound-projection directivity. The projector assembly is manufactured of
plastic and finished in black. The driver is finished in black baked
epoxy for optimum durability and corrosion protection. Units are
shipped complete with all components and installation data for field
installation. Replacement head assembly (Model K-370A) or driver
assembly (Model SD-370A) are available for field replacement.
SEVEN
Model HPG-370GA provides optimum sound level output of 120dB
(measured at 1600 Hz, rated power, 3 meters on axis) and features a
directed dispersion range of 120H° x 140V° (1 kHz octave band) to
assure high-intensity acoustic penetration for electronic siren signals.
Product series is suitable for use with matched amplifier and control
equipment in systems requiring AMECA (Automotive Manufacturer
Equipment Compliance Agency, Inc., formally the AAMVA) certification
to General Services Administration specifications (KKK-A-1822C).
