The e-Q2B has been completely redesigned to incorporate 200W Class D audio amplifier for increased reliability.

In addition, external diagnostics have been added to monitor power, output voltage and current monitoring. New 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. Finally, an audio output has been added to allow the e-Q2B to work with the Federal Signal Rumbler Intersection Clearing System.

Improved Keypad

The push-button backlit, membrane switches and robust rubberized knob provide tactile feel to easily activate siren tones, airhorn, PA and radio rebroadcast. In addition, the detachable push-to-talk microphone can be easily removed and replaced with c(more...)
