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!

Installation:
This bracket will
mount to the front
bumper, using the
bolts that hold the
bumper on.
WARNING: When
you install 2 siren
speakers, install 1
at a time so that
you are not removing
both bumper supports at the same time.
1. On the side of the vehicle that you will be installing the bracket,
remove the 2 bolts that hold the bumper and it's support to the
vehicle. Secure the mounting bracket to the bumper using these 2
bolts as you re-install the bumper.
2. Next install the bracket support. Loosen the 2 rear bolts that secure
the hood latch to the vehicle (Fig. 1) just enough to slide the support
underneath. The slots in the support fit around 2 of the bolts you
loosened. Tighten the 2 bolts to secure the support.
IMPORTANT NOTE: Make sure that the
supports bolts are tightened securely to
vehicle specifications. Also be sure not to
overtighten and strip the nuts.
3. Loosely attach the straps to the bracket as shown.
Slide the siren speaker between the straps and
secure the speaker to the bracket (adding spacer)
while also securing it to the support you installed
in step 2.
4. Repeat procedure for the other side of the vehicle.
5. Extend the WHITE (Negative) and BLACK
(Positive) speaker wires to your siren amplifier
and connect as described in the amplifier manual.
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.
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!
