Product Description

The Federal Signal Q-Siren Q2B Series Electromechanical Sirens deliver the distinctive, powerful warning sound that has become a tradition in the fire service. Designed for fire apparatus and emergency response vehicles, the Q-Siren combines classic styling, durable construction, and proven electromechanical technology to provide exceptional audible warning performance.

Iconic Electromechanical Siren Performance

The Q-Siren produces its unmistakable warning tone through a powerful motor-driven mechanical siren assembly. Unlike electronic sirens that reproduce warning tones through speakers, the Q2B generates its distinctive sound mechanically, providing a recognizable long-distance warning signal.

Featuring a heavy-duty coaster clutch, the Q-Siren continues producing its characteristic coast-down sound after power is removed, reducing electrical current draw while extending the audible warning. A standard electric brake allows operators to quickly stop the siren when needed.

Durable Construction and Mounting Options

Built for demanding fire apparatus applications, the Q-Siren features a streamlined, polished exterior available in traditional Chrome and Black Chrome finishes. Pedestal-mounted configurations provide a classic bumper-mounted appearance, while recessed models accommodate integrated bumper installations.

Optional mounting brackets and foot switch accessories are available to accommodate different installation and operational requirements.
