Completely Redesigned
The e-Q2B® includes 200 W Class D audio amplifier for increased reliability and external diagnostics to monitor power, output voltage and current monitoring. Features include park kill input, which immediately shuts off the siren when vehicle is in park and horn ring input which allows the user to cycle through siren tones. The e-Q2B also has an audio output to work with the Federal Signal Rumbler Traffic Clearing System.

Improved Amplifier
Using DSP circuitry, the e-Q2B amplifier is able to accurately reproduce the  trademarked “Q” wail rather than relying on a simple digital recording. DSP also enables the product to function either manually or automatically for hands-free operations (Horn Ring Transfer). The new Class D engineered system reduces operating current to 20 A and provides for a more robust, reliable system.

Improved Keypad
The push-button backlit, membrane switches and robust rubberized knob provide tactile feel to easily activate siren tones, air horn, PA and radio rebroadcast. In addition, the detachable push-to-talk microphone can be easily removed and replaced with customized plug. Volume control for microphone is located directly on the keypad for added convenience.

Optional Siren Control
Three external inputs allow for the use of externally configured foot switches to control manual wail, brake and air horn.

Registered Trademark
The distinctive sound of the Q2B electro-mechanical siren is a registered trademark owned by Federal Signal Corporation.
