When you're driving an emergency vehicle, you know civilians on the road can't see the lights or hear the siren -- or at least that's how they act. With theRumbler fromFederal Signal, drivers can now feel your approach. In addition to the primary siren amplifier and speaker, the Rumbler adds a secondary amplifier, timer and a pair of woofers. This enables it to sense the siren-tone signal, reduce the signal frequency by 75%, and amplify the sound through the high-output woofers. The system's timer allows the tone to sound for 10 seconds and then automatically shut off. The result is a highly effective backup emergency tone, especially handy when transitioning hazardous traffic intersections. It's also particularly useful in dense urban environments, with heavy vehicle and pedestrian traffic.
