An electromechanical siren used mostly by fire departments. The distinct sound provides recognizable long distance warning and it utilizes a unique clutch design that provides a longer coast down sound while reducing the amp draw. It produces 123 decibels at 10-feet.
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 powerful warning sound, more than any other electromechanical siren.
