Standard & High-Power Siren Loudspeaker Assemblies
HPG-100N Atlas Sound siren loudspeaker HPG-100N is a reflex-type loudspeaker with a rectangular molded bell. It
is rated at 100 watts RMS in electronic siren use. HPG-100N provides optimum sound level output of 120 dBA (measured at 1600 Hz, rated power, 3 meters on axis) and features a directed dispersion range of 80˚ x 105˚ (1 kHz octave
band) to assure high-intensity acoustic penetration for electronic siren signals. Unit contains the patented Atlas Sound
AS-100N compression driver 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 heavy-duty, one piece steel mounting bracket 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-100N) or driver assembly (Model AS-100N) are available for field replacement.
