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 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 siren “hands-free.”

Important Warning for Police Boats and Fire Rescue Boats
It has come to our attention that police boat and fire rescue boat sirens and speakers may subject persons operating those craft to sound pressure levels that can cause permanent hearing loss. We recommend that speakers be located as far forward on the boat as possible, as recommended in the SAE Recommended Practice J1849 "Emergency Vehicle Sirens". However, unprotected exposures of a sufficient duration to properly located siren speakers can still create a risk of hearing loss.
It is our recommendation that your siren speakers should be relocated and persons operating these craft should wear hearing protection when using the siren system.
Failure to comply with these recommendations may result in temporary or permanent hearing loss to operators and passengers of these vehicles.
