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 higher­frequency 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!

Installation:

This bracket will mount to the outside of the frame toward the front
(just behind the tow hook) using existing hardware (Figs. 2 & 3).

1. Secure the speaker to the bracket using the suppled 5/16 X 1” HEX
HEAD SHEET METAL SCREWS (Fig. 1).

2. Secure the bracket to the vehicle by removing the 2 existing bolts
from the frame and securing the siren bracket using these bolts.
(Figs. 2 or 3)

IMPORTANT: The slotted holes on the siren body must face down,
toward the road for proper drainage.

3. Extend the WHITE (positive) wire and the BLACK (negative) wire to
your siren amplifier and connect as described in the amplifiers
instructions.

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!

IMPORTANT! Before returning the vehicle to active service, confirm
the proper operation of this product, as well as all vehicle
components/equipment.
