Features

The Rumbler®  is a traffic-clearing system that demonstrates Federal Signal’s long-standing commitment as the technological leader in audible warning and operator safety. Rumbler police siren provides a secondary, low-frequency duplicate tone to penetrate solid materials, allowing vehicle operators and nearby pedestrians to feel the sound waves.

The low-frequency emergency vehicle siren senses the primary siren tone signal and reduces the signal’s frequency by 75%. It then amplifies the sound through a pair of single high-output speakers. This cutting-edge fire truck and patrol car siren allows the tone to sound for eight seconds, provides a highly effective warning, and automatically shuts off.

Federal Signal’s fire truck and patrol car siren includes two new variations. The Rumbler Solo is a single speaker, allowing for easier and faster installation. The compact Rumbler low-frequency car siren has a pair of compact speakers allowing for additional mounting locations. The Rumbler siren system works 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.

Our low-frequency emergency vehicle siren is also available with a Rumbler amplifier, providing Rumbler features 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 a 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.
