Features

Rumbler Diagram

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

Improves Traffic Warning Effectiveness
Rumbler provides a secondary, low-frequency duplicate tone. Low-frequency tones have the distinct advantage of penetrating solid materials allowing vehicle operators and nearby pedestrians to feel the sound waves.

Rumbler senses the primary siren tone signal and reduces the signals’ frequency by 75%. It then amplifies the sound through a pair of or single high-output speakers. The system’s timer allows the tone to sound for eight seconds, provides a highly effective warning, and automatically shuts off.

Secondary System with Built-in Safety
Rumbler low frequency speakers include two new different variations. The Rumbler Solo is a single speaker, allowing for easier and faster install. The Compact Rumbler low frequency speakers are a pair of compact speakers allowing for additional mounting locations.

Rumbler low frequency speakers work in conjunction with Federal Signal sirens that feature integrated Rumbler Traffic Clearing capability. This allows the sirens to produce a Rumbler tone without the need for a separate externally mounted amplifier.

Rumbler low frequency speakers are also available with a Rumbler amplifier, providing Rumbler feature to other Federal Signal sirens.

Vehicle specific mounting hardware is available and ordered separately.

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.
