Federal Signal Q Siren

An Iconic Fire Truck Siren
It's not a fire truck unless it's got a Q-Siren. With more than 50 years of fire service tradition and history, the Federal Signal Q-Siren® (model Q2B®) is a beautifully streamlined, chrome-plated fire truck siren designed to provide unparalleled reliability for long-life operation. When mounted on a fire truck, the Q-Siren delivers a powerful warning sound, more than any other electromechanical fire truck siren.

The Q-Siren is available in traditional chrome and black chrome. The traditional chrome models compliment the fire truck’s chrome bumper finish while the black chrome is ideal for blacked-out fire trucks.

Longer Coast-Down Sound
A heavy-duty coaster clutch is standard on Q2B models. The unique coaster clutch design enables the fire engine siren to deliver a longer coast-down sound once power is removed to reduce battery drain. The “worry-free” clutch is subject to very little wear and requires no
service attention or adjustments. Use the standard electric brake to silence the fire engine siren quickly.

Pedestal or Recessed Mounting
The Q-Siren is available in two Q2B models. The Q2B-012PSD and Q2B-P-BLK come with a pedestal for bumper mounting and the Q2B-012NNSD and Q2B-NN-BLK are designed for recessed mounting in the bumper.

For flat and curved apparatus bumpers, a special bracket, the Q-MT, is available. This rugged, durable mount is easy to install. Constructed of tough 3/8-inch steel, the Q-MT design protects the siren from the impact of rough roads.

Hands-Free Operation
For increased convenience, the Q2B-SWKIT foot switch kit is also available. The kit comes with everything necessary to wire a foot switch to any Q2B model, enabling the operator to power the fire truck siren “hands-free.”
