Introduction
The Federal Signal
R
umbleR
®
2 Low Frequency Siren Amplifier incorporates the latest solid-state designs
for superior reliability and sound quality. The
R
umbleR
2
uses the output of a standard emergency vehicle
siren and synthesizes a low frequency signal. It then amplifies that signal to drive a Federal Signal Low
Frequency Siren Speaker.
The amplifier’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 traffic intersections.
The
R
umbleR
2
is designed for use in negative-grounded vehicles with 12-volt electrical systems. It can be
mounted in a variety of positions.
Features
