Installation:
The passenger and driver side siren speaker brackets
both mount in the same manner. The passenger side is
shown here.
1. Secure the mounting straps (with spacer) to the siren
speaker tightening only the single bolt side.
IMPORTANT! The slotted holes in the siren speaker
must face down toward the road after mounting so that
water will not be trapped inside.
2. Secure the speaker bracket to the passenger (or
driver) side mounting bracket.
3. Secure the siren speaker to the speaker bracket you mounted in step 2 (Fig. 2).
Tighten all mounting hardware firmly.
4. Remove the 2 bolts that hold the tow hook onto the vehicle (Fig. 1).
5. Slide the mounting bracket between the tow hook bracket and the vehicle and
secure both to the vehicle using the tow hook mounting hardware.
6. Extend the BLACK (-) negative and WHITE (+) positive wires to your siren
amplifier and connect as described in the amplifiers instructions.

equipment
IMPORTANT! READ THESE
WARNINGS BEFORE CONTINUING!
The Howler™ Supplemental Siren was
designed for use in high-risk areas such as an
intersection. It is not intended to be, nor
should be operated as a replacement or
alternative to the vehicle’s primary siren.
The low-frequency tones of the Howler™
demonstrate significantly different audio
characteristics as compared to those of a
traditional higher-frequency siren. While the
low-frequency tones are better able to
penetrate other vehicles, thus alerting drivers
to the presence of the responding emergency
vehicle, these tones may also penetrate into
the responding vehicle itself. This could
potentially expose the operator to increased
noise levels.
To help eliminate overexposure,
the Howler™ siren has been
designed with a built-in timing
circuit. The Occupational Safety
& Health Administration (OSHA)
(www.osha.gov) provides
information necessary to
determine safe exposure times in
Noise and Hearing Conservation,
Section 1910.95 (Occupational
Noise Exposure). Until you have
determined the safe exposure
times for your specific
application, this siren should be configured for the
minimum operating time and operators should be
required to use an approved hearing protection
device. FAILURE TO FOLLOW THIS
RECOMMENDATION COULD CAUSE HEARING LOSS!
