Because of the unit's ruggedness and compact size, it is suitable for installation within standard-sized lightbars, engine compartments, or for mounting in front of the radiator or on the bumper of any ambulance, fire, law enforcement, utility, or other public service vehicle. 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. 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. 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. 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).
