The Model E was a series of 4 small vehicular directional electromechanical sirens introduced in mid-1949 by Federal Enterprises (later Federal Sign & Signal and Federal Signal Corporation) as a budget option in their vehicular siren lineup. Favorable for concealed mounting, the Model E series, particularly the Model EG, proved to be very popular and was produced until the late 1970s when it was superseded by the Model Q.
Design
Model EG
The Model EG consists of an 8-port rotor and stator which has a grille bolted to the front of the rotor to prevent debris from entering it. 16-port units were also offered under the name "Model EGH". On Model EG stators, finger guards are located on each port to prevent injury, as the siren is small enough to be handheld; Model EGH stators lack finger guards entirely. The rotor is driven by a small 6 or 12 V motor which is enclosed in a cylindrical housing that has a rounded rear. Units with one positive ground wire as opposed to 2 positive and negative wires simply have "E" stamped on them instead of "EG". The siren is held up by a small pedestal mount which is bolted to the bottom of the motor cover. 2 holes on each end of the pedestal's ovular base allow the siren to be mounted to a flat surface. The Model EG is around 8" long, 7½" tall, and 5⅞" wide, and weighs 8¼ lbs. The siren comes in a chrome finish. The Model EG was the most popular of the two, with most existing Model E units being Model EGs.
Model EP
The Model EP consists of an 8-port rotor and stator which has a large, flared horn bolted to the front of the stator to increase the siren's sound output. 16-port units were also offered under the name "Model EPH". On Model EP stators, finger guards are located on each port to prevent injury, as the siren is small enough to be handheld; Model EPH stators lack finger guards entirely. A mesh screen is also located in front of the stator for the same reason. Units with one positive ground wire as opposed to 2 positive and negative wires simply have "E" stamped on them instead of "EG". The rotor is driven by a small 6 or 12 V motor which is enclosed in a cylindrical housing that has a rounded rear. The siren is held up by a small pedestal mount which is bolted to the bottom of the motor cover. 2 holes on each end of the pedestal's ovular base allow the siren to be mounted to a flat surface. The Model EP is around 12½" long, 7½" tall, and 8⅛" wide, and weighs 9¾ lbs. The siren comes in a chrome finish. While largely overshadowed by the Model EG, the Model EP was still relatively popular, and a good number of units exist today.
