False Alarm Recorder Tested in New York
A photo electric fire alarm recorder which makes four feet of motion picture film of a person snapping the handle on the door of a single-action firm alarm telegraph box, was demonstrated in front of the New York City Hall on Monday, June 17th, as part of public ceremonies attendant upon the presentation of medals to members of the New York Fire Department for personal valor in the line of duty during the year 1928.
Mayor James J. Walker was photographed in the act of turning the handle on the alarm box. The contrivance is a motion picture camera containing 25 feet of film. The camera is rigged on a yard-arm from the top of the box. The yard-arm makes a half-circle every time the handle of the box is pulled. A siren also howls for about five seconds and attracts public attention, while the camera makes a picture of the area immediately in front of the box. A 1,000-watt lamp also lights simultaneously with the snapping of the box handle in order to illuminate the area in the night time.
