All of the Tradition of the Q-Siren™ at a Fraction of the Amp Draw
The Federal Signal 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 speaker output of 200-watts to accurately
reproduce the distinctive sound of the Q-siren while using less current draw.
Powerful Amplifier with State-of-the-Art DSP Technology
Using DSP circuitry, the e-Q2B’s amplifier is able to reproduce the true “Q” sound
rather than relying on a simple digital recording. DSP also enables the product to
function either manually or automatically for hands-free operation.
Digital Output Controller Activates Siren Functions
This state-of-the-art controller digitally transmits and prioritizes end user commands.
The control head/amplifier interface utilizes solid-state digital decoding, which
minimizes interconnection complexity.
The Digital Output Controller allows the end-user to operate several siren functions.
The traditional “Q” wail can activate in automatic or manual modes. Additional
features include a yelp, “Q” brake, digitally recorded air horn, PA, radio rebroadcast,
and a detachable push-to-talk microphone with volume control.
The controller provides three external inputs. These inputs allow for the use of
externally configured foot switches to activate the manual wail, brake, and air horn
Unlike other siren systems, the PA feature offers bandwidth to 10 KHz and a true
200-watts of clear PA power.
Designed to Reduce Radio Frequency Interference
