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. 

Compatible Federal Signal Siren Models 
The Following Federal Signal siren models are compatible with the Rumbler System when used with a Federal Signal speaker(s).

*Note: EQ2B(Legacy) amplifiers are not compatible.

Pathfinder Integrated Rumbler Capability

  • Pathfinder + (1) 100 W siren speaker = single-tone, standard PA 
  • Pathfinder + (2) 100 W siren speaker = dual-tone, standard PA 
  • Pathfinder + (1) 100 W speaker + (1) or (2) Rumbler woofers = single tone, Rumbler, Enhanced PA 
  • Pathfinder + (2) 100 W siren speakers + RUMBLER-3 (includes two woofers) = Rumbler, dual-tone siren, standard PA (one channel will Rumble)
  • Pathfinder + (1) or (2) Rumbler woofers + (2) 100 W siren speakers + MS4000 = dual-tone, Rumbler, Enhanced PA

Warnings

Warnings

Audible Equipment may produce LOUD sounds necessary to request the right-of-way. Audible equipment may cause hearing damage. Wear hearing protection. Refer to the Installation Manual or call 800/433-9132 for further instructions.
 
Important Warning for Police Boats and Fire Rescue Boats
It has come to our attention that police boat and fire rescue boat sirens and speakers may subject persons operating those craft to sound pressure levels that can cause permanent hearing loss. We recommend that speakers be located as far forward on the boat as possible, as recommended in the SAE Recommended Practice J1849 "Emergency Vehicle Sirens". However, unprotected exposures of sufficient duration to properly located siren speakers can still create a risk of hearing loss.
It is our recommendation that your siren speakers should be relocated and persons operating these craft should wear hearing protection when using the siren system.
 
Failure to comply with these recommendations may result in temporary or permanent hearing loss to operators and passengers of these vehicles.
