The Federal Signal SD-10 was a dual-toned, 9/12 port, 10HP electromechanical siren produced by the Federal Sign & Signal Corporation. It shared the same rotor and stator assembly with the Model 5AT/5BT. It was produced from the late 1950's to the late 70's where it was discontinued. There were 2 models produced: The SD-10A is the most common model and is powered by 240V 3-phase power and the SD-10B which runs off of 240V single-phase power. It produces a sound of 109dB at 100 feet, and weighed about 500 pounds.
