With over 50 years of fire service tradition and history, the Federal Q2B® is a beautifully streamlined, chrome-plated siren designed to provide unparalleled reliability for long-life operation. When mounted on emergency vehicles, the Q2B delivers powerful warning sound, more than any other electro-mechanical siren.

 

 A heavy-duty coaster clutch is standard on Q2B models. The unique coaster clutch design allows the siren to deliver longer coast-down sound once power is removed, reducing battery drain. The “worry free” clutch is subject to very little wear and requires no service attention or adjustments. Use the standard electric brake for quick silencing of the siren.

 

Two Q2B models are available. The Q2B-P comes with pedestal and housing for on the bumper mounting. Q2B-NN is designed for recessed mounting in the bumper.
