The Federal Signal 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 improves intersection warning effectiveness by introducing a revolutionary new concept to audible warning through its ability to interact with most 100/200-watt siren amplifiers and provide secondary, low frequency duplicate tones. Low frequency tones have the distinct advantage of penetrating solid materials allowing vehicle operators and nearby pedestrians to FEEL the sound waves.

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 eight seconds, 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. A complete Rumbler intersection-clearing system consists of an amplifier, with built-in timer and two subwoofers. Vehicle specific mounting hardware is ordered from the drop-down list. This system can be paired with most 100/200-watt emergency siren amplifiers.
