DANGER! Sirens produce extremely loud emergency warning tones! Exposure to these tones without

proper and adequate hearing protection, could cause ear damage and/or hearing loss! The Occupational Safety &
Health Administration (www.osha.gov) provides information necessary to determine safe exposure times in
Occupational Noise Exposure Section 1910.95. Until you have determined the safe exposure times for your
specific application, operators and anyone else in the immediate vicinity should be required to wear an approved
hearing protection device. FAILURE TO FOLLOW THIS RECOMMENDATION COULD CAUSE HEARING LOSS!

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!

IMPORTANT: It is the responsibility of the installation technician to make sure that the installation and operation of this product will not interfere with or
compromise the operation or efficiency of any vehicle equipment!

Installation:

IMPORTANT: The slotted holes in the siren speaker must face toward
the road after mounting for proper drainage.

1. Bracket mounts to vehicle frame behind front fender on driver side
(Fig. 1). Secure Howler siren speaker to Lower Support Bracket
using supplied 5/16 X 1” Hex Head Sheet Metal Screws (Fig. 2).

2. Loosely secure Lower Support Bracket (around vehicle frame) to
Upper Support Bracket using supplied 5/16 Flat Washers, 5/16 Split
Lock Washers and 5/16 - 18 X 1 Hex Head Bolts (Fig. 3).

3. Line holes in the frame up to circular raised area on both support
brackets and install 3/8 - 16 X 4” Hex Head Bolt, 3/8” Flat Washer
and 3/8 - 16 Elastic Stop Nut through
brackets and frame as shown
(Figs 3 &. 4).

4. Tighten all mounting hardware (Fig. 4).

5. Extend BLACK (-) negative and WHITE (+) positive speaker wires to
amplifier and connect as described in amplifier instructions.

IMPORTANT! When routing wires, it is important to choose a path that will
keep the wires away from any excessive heat or from any vehicle
equipment that could compromise their integrity such as trunk lids, door
jams, etc...
