Because of its compact size, the unit can be mounted under the hood, in front of or behind the radiator, or near a fender-well of most fully equipped vehicles. The HPH-370B (conservatively rated at 100 watts RMS in electronic siren use) is recommended for high-powered systems in public safety, civil authority, military, or emergency medical applications. GENERAL DESCRIPTION Atlas Sound HPH-370GB siren loudspeaker is a double re-entrant type directional model with a 100-watt power rating. The assembly is compact in size and styled specifically for concealed installation in limited space applications. Units can be mounted to any ambulance, fire, law enforcement, utility, or other public service vehicle. A unique, heavy-duty, steel mounting bracket permits full-axis orientation of the loudspeaker for preferred sound-projection directivity. The projector assembly is manufactured of welded, heavy-gauge steel and finished in black baked epoxy for optimum durability and corrosion protection. HPH-370B contains the patented Atlas Sound SD370A compression driver (U.S. Patent #7,760,501) complete with a non-fatiguing, self-aligning sound chamber assembly. Units are shipped complete with all components and installation data for field assembly. (Replacement head assembly, Model K-370A for replacement driver assembly, SD-370A, is available for field replacement). HPH-370B 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).

Prior to assembly, crimp or solder the interconnecting cable from the amplifier output to the quick-connect terminals supplied. (Do not solder cable directly to the driver connection terminals.) Phasing must be observed in all installations of more than one loudspeaker. The black terminal is common. Assemble all components and hardware in sequence as illustrated. Driver must be oriented with drain hole in downward position. Rotate loudspeaker on axis for desired forward sound projection; then securely hand tighten reentrant tip assembly.
