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 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 siren.
The Q-Siren is available in traditional chrome and black chrome. The traditional chrome models are a compliment to 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 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 siren quickly.
Pedestal or Recessed Mounting
The Q-Siren is available in two Q2B models. The Q2B-012PSD and Q2B-P-BLK comes 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.
For increased convenience, the Q2FSK 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 siren “hands-free.”
