Introduction

The Federal Signal RumbleR® 2 Low Frequency Siren Amplier incorporates the latest solid-state designs
for superior reliability and sound quality. The RumbleR 2 uses the output of a standard emergency vehicle

siren and synthesizes a low frequency signal. It then amplies that signal to drive a Federal Signal Low

Frequency Siren Speaker.

The amplier’s adjustable 8–60 second timer enables the tone to sound for the selected interval and then
automatically turns it off. The result is a highly-effective backup emergency tone, especially when crossing
hazardous trafc intersections.

RumbleR 2 is designed for use in negative-grounded vehicles with 12-volt electrical systems. It can be

The
mounted in a variety of positions.
