By 1915, they began manufacturing and selling electrically-operated mechanical sirens (such as the Q Siren and the Model 66 Siren). During this time, Federal Electric came under the ownership of Commonwealth Edison eventually becoming a part of the utility empire of Samuel Insull. By the 1950s, they began manufacturing fire/air raid sirens, including the Federal Signal Thunderbolt series and the Federal Signal 3T22 and 2T22, usually used for warning of air raids or fallout during the Cold War. Longtime engineer Earl Gosswiller patented the Beacon-Ray and TwinSonic products, which set the standard for emergency vehicle lightbars. In 1956, the company became a corporation, renaming itself "Federal Sign and Signal Corporation". By this time, it made outdoor warning sirens, police sirens, fire alarms, and outdoor lighting. By 1961, Federal Sign and Signal had gone public, trading on the NASDAQ market. In 1976, the company became Federal Signal Corporation. By 1990, the company began to drop many of its older outdoor warning siren products (e.g. the Thunderbolt, SD-10, Model 5 & 7, 3T22, etc.) and focused on designing and producing newer products. In 1988, it released a new product: the Federal Signal 2001 series warning siren. This siren is capable of running via a direct current (DC) power source, such as an AC-to-DC inverter, solar energy, and 4 12VDC series-connected batteries at 48 volts DC. Today, the company produces the battery-operated ''2001-130'', a mechanical siren which is rated at 130 decibels at . On Feb 22, 2000, Federal Signal Corporation announced the signing of a definitive agreement for the acquisition of P.C.S. Company ("P.C.S."). On June 27, 2005, Federal Signal Corporation announced the signing of a joint venture agreement to establish a Chinese company, Federal Signal (Shanghai) Environmental & Sanitary Vehicle Company Limited, based near Shanghai, China. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Federal Signal Corporation」の詳細全文を読む スポンサード リンク
