Federal Signal’s state-of-the art e-Q2B electronic siren carries on the tradition of our classic Q2B® electro-mechanical siren. The e-Q2B combines Digital Signal Processor (DSP) technology with a true 200 watts of speaker output to reproduce genuinely and accurately the distinctive sound of the Q-siren at a fraction of the current draw.

The e-Q2B is comprised of a 200-watt DSP Amplifier, and a Digital Output Controller. These components work together to generate the recognized sound of Federal’s Q-siren. In addition to the recognizable “Q” sound, the e-Q2B provides all of the functionality of an electronic siren with PA.

Q2B OR e-Q2B – THAT IS THE QUESTION!!! The e-Q2B electronic siren is the right choice for your smaller apparatus or ambulance when you want the same penetrating, long distance warning of the electro-mechanical Q2B without the current draw requirements. The e-Q2B produces the bona fide “Q” sound with only 30 amps of continuous current draw. With the e-Q2B, you can put the sound of the “Q” on vehicles in your fleet whose electrical systems previously could not support a Q-siren. When you cannot use the original Q2B, specify the e-Q2B.
