The Federal Signal Model L is a general-purpose electro-mechanical siren that produces a distinctive sound and tonal quality for industrial applications. It has a low maximum pitch which provides excellent contrast to industrial ambient noise. Introduced in 1946, the Model L is still used today in many rugged and extreme environments and applications.
The Model L features a universal motor and operates with 120VAC/125VDC. The Model L is also available for 240VAC/250VDC operation. The fractional horsepower motor drives a ported aluminum rotor within the specially designed stator to produce a unique sound. The recommended duty cycle is five minutes on/five minutes off. This siren produces an attention-getting 112dBa @ 10 feet (122dBa @ 1m).
The Model L's metal housing is sealed with red powder coat for an attractive appearance and superior corrosion resistance. The swivel mount bracket accommodates wall and surface mount installations.
The Model L is CSA Certified.
