			FEATURES
			• 100-Watt Power Handling with High Intelligibility and Sound Penetration
			• Rugged, All-Metal, Weather-resistant Construction
			• Specifically Designed for Concealed Installation in Electronic Siren and Signalling Applications
			APPLICATIONS
			Utilize the HPH-370GB re-entrant, directional loudspeaker for concealed installation in electron-
			ic signal, alarm, public address, and other high-intelligibility, mobile emergency communication
			and signaling applications. 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 recommend-
			ed 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 brack-
			et 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
	5.812"		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
4.7"			systems requiring AMECA (Automotive Manufacturer Equipment Compliance Agency, Inc.,
			formally the AAMVA) certification to General Services Administration specifications
			(KKK-A-1822C).
