The Rumbler®, intersection-clearing system, demonstrates the long-standing commitment of Federal Signal to continue as the technological leader in audible warning and operator safety. The Rumbler® system senses the primary siren tone signal, and reduces the signals’ frequency by 75%. It then amplifies the sound through a pair of high output woofers. The system’s timer allows the tone to sound for eightseconds, providing highly effective warning at hazardous intersections, and then automatically shuts off. The Rumbler® is particularly effective when used in dense urban environments with heavy vehicle and pedestrian traffic.
