- Low-frequency tones work simultaneously with primary siren
- Produces penetrating/vibrating low-frequency sound waves
- Interacts with most 100/200 W emergency vehicle siren amplifiers
- Enabled via any emergency vehicle steering wheel horn ring
- Eight second safety timer provides automatic tone shutdown
- Highly effective in dense urban environments with heavy vehicle traffic
- Three-year warranty
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, providing a highly effective warning, 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 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.
