Introduction

The ETSA100E and ETSA300MF Multi Function Siren Amplifier are
premium 200W units designed for single or dual 100W speaker use. The
sirens comes standard with a noise-cancelling microphone for PA use. The
amplifier box contains a single amplifier capable of supplying sound to
either 1 - 100 Watt or 2 - 100 Watt speakers. The ETSA300MF also
includes a 4 position slide switch and 4 independently controlled accessory
switches each capable of supplying 20 amps.

The primary operating modes are Piercer, Yelp, Wail, Hi-Lo, and Super
Hi-Lo, Manual, and Radio. A Noise Canceling PA Override, a push-button
Horn Override, and a push-button Manual Override are available in all
modes. All tones except wail and yelp for California Title 13 compliance
may be disabled by removing a jumper located on the PCB.

Sirens provide an essential function of an effective audio / visual warning
system. However, sirens are only short range secondary devices. The
use of a siren does not insure that all drivers can or will abide by or react to
an emergency warning signal, especially at high rates of speeds or long
distances. The operator of the vehicle must never take the right of way for
granted and it is the operator's responsibility to proceed safely.

The effectiveness of this siren system is highly dependant on the correct
mounting and wiring. The installer must read and follow the manufacturer's
installation instructions and warnings in the manual. The vehicle operator
should verify the siren system is securely fastened to the vehicle and
properly functioning.

Effective sirens generate loud sound pressure levels that can potentially
cause hearing damage. Installers and those around the vehicle need to be
aware of the dangers and wear hearing protection whenever the siren
system is operating. Vehicle operators and occupants should assess their
exposure to siren noise and determine what steps need to be taken to
prevent hearing damage.

The siren system is intended for use by authorized personnel only. It is the
user's responsibility to ensure they understand and operate the emergency
warning devices in compliance with all applicable city, state, and federal
laws and regulations.

SoundOff Signal assumes no liability for any loss resulting from the use of
this warning device.

WARNING: Warning devices are strictly

regulated and governed by Federal, State
and Municipal ordinances. These devices
shall be used ONLY on approved vehicles.
It is the sole responsibility of the user of
these devices to ensure compliance.
