Overview
When clear, unmistakable audible alerts are critical, the Federal Signal A-120 electromechanical siren delivers reliable, high-pitch warning tones that cut through heavy industrial noise to protect people and assets. Designed as an industrial siren for alarm, security and monitoring applications, the A-120 uses a ported aluminum rotor driven by a fractional-horsepower motor to produce a distinctive tone that stands out in noisy environments. The unit ships in a sealed red powder-coated metal housing that resists corrosion and is built for surface or wall mount installations (swivel bracket included). Rated for 120V operation and featuring an internal cooling fan, the A-120 is recommended for intermittent duty (5 minutes on/5 minutes off) and offers low maintenance and long service life. Made in the USA by Federal Signal, this model is ideal for manufacturing floors, yards, loading docks, and critical infrastructure where security, surveillance and monitoring systems need an effective audible layer. Add the A-120 to your facility notification plan today or contact us for application guidance and installation support.
