New Jersey	Ramsey		1	B	Yes	Yes	Unk	Horn is on Their Island Ave. Fire Headquarters. Boxes
New Jersey	Raritan Borough Fire Dept.		2	Unk	Yes	No	Unk	Diaphones at both its firehouses. Activated by the Gamewell fireboxes the Diaphones blew three rounds of the 2 or 3 digit box number until April 1998. When the boxes and circuits were removed the Diaphone at the North Thompson St. firehouse 1956 was silenced. During a renovation in 2000 the air compressor system and the Diaphone were removed. The Diaphone located on top of the hose-drying tower at the historic 1883 firehouse at 16 Anderson St. Was converted by myself to a radio system activated by our Plectron paging system that sounded 3 rounds of 5 Call To Quarters. This system has just recently been turned off May 2003 during an exterior building renovation so as not to blow the workers off the roof. This is an historic renovation to restore the building to the way it looked in 1883 pre Diaphone. The Diaphone has been moved into the tower behind the louvered vents. I have not had an opportunity test the system as work continues. It is doubtful that it will return to regular use again. Noise complaints from neighbors were becoming more vocal. It makes no sense to annoy the community that this department depends on for financial support. The neighboring town Of Somerville still utilizes boxes and I think 3 horns. - Lou Laine Engineer Raritan Fire Department

We use a Harrington Air Control Panel and electric solenoid to operate our horn. When our Gamewell valve did not work the cost for rebuilding the valve was more than the Harrington valve. It does not have the traditional two tone sound of the Gamewell valve but is very reliable. Our horn originally operated 24 hours a day but due to the use of pagers and complaints from the public we only operate the horn from 8:00am to 9:00pm. Steve Freeman

Virginia	Covington	Alleghany	1	Unk	No	No	Unk	The air horn is no longer in service. The Gamewell system was taken out of service in the 1950s however we continued to use the horn into the 1980s. Our dispatchers activated the air horn manually from our dispatch center using two Gamewell alarm boxes one for fire calls and one for rescue squad calls. We even relocated the horn compressor air tank and Gamewell boxes when we moved into a new station in 1969. By the 1980s all firefighters and squad personnel were carrying pagers and the horn was aggravating our neighbors. We actually had two horns one in service and the other ready to install when the one in service required maintenance. Neither horn can be located at this time however your inquiry has renewed an interest in finding them again for display with other fire memorabilia. The Gamewell boxes air tank and compressor are still in place. Jerry Burks - Ex Chief
