• The power-packed, entry level siren in our family is the 3V8-H. With over 3,000 units in service world-wide, this rock solid unit has seen it all. At a price point anyone can appreciate, this siren is 100% FEMA and USDA grant compliant. With a 5 HP, continuous duty motor pushing its aluminum rotor, this siren produces 109 dB(c) @ 100 ft. continuously*. Peak volume is not just for 25% of its cycle time, like its rotating competitors, but for 100% of its full RPM run time. Plus, the sound output is produced in a 460 Hz tone, the lowest pitch in the industry. Therefore, its sound will fade at a lower rate than its competitors, giving the user more distance per decibel. This pitch has been shown to stand up to wind fade and tree cover better than its high pitch competitors.
