Rumbler Diagram

 

The Rumbler®, traffic clearing system demonstrates the long-standing commitment of Federal Signal to continue as the technological leader in an audible warning and operator safety.  

Improves Traffic Warning Effectiveness
The Rumbler introduces a revolutionary new concept to audible warning through its ability to interact with most 100/200 W 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.

 Secondary System with Built-in 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 eight seconds, provides a highly effective warning, and automatically shuts off. The Rumbler is particularly effective when used in dense urban environments with heavy vehicle and pedestrian traffic.  

A complete Rumbler traffic clearing system consists of an amplifier, with built-in timer and two subwoofers. Vehicle specific mounting hardware is ordered separately. This system can be paired with most 100/200 W emergency siren amplifiers.
