Federal Signal 6H Air Horn, 6, High Pitch - 6H
Federal Signal air horns feature a one-piece, cast aluminum alloy housing which has been treated to provide corrosion resistance. The horns include specialized long-lasting stainless steel diaphragms. These precisely machined horns will yield peak performance at proper working air pressures and are virtually indestructible. The Model 6H has threaded female pipe connections and features flanges for additional support. Federal Signal air horns operate with 20 to 150 p.s.i., (pounds per square inch) but they are tuned for 80 to 90 p.s.i. operation. The horn frequency (pitch) depends on both the diameter and length of the projector. Decibel output at 10 feet is 122dBa (132dBa @ 1m). The horns require a 120VAC Federal Signal Model EVL air valve (sold separately). This horn can also be operated with a manually operated valve in areas where no electricity is available. In either case, there must be an air supply available for the horn to operate (sound). Air horns can be used indoors, outdoors, or anywhere compressed air can be provided. Federal Signal Air Horns are the loudest audible signals offered for indoor applications. They are not subject to sparking and are ideal for hazardous locations (the valves need to be located in a non-hazardous location). 5 Year Limited Warranty.
