Securing the siren speaker to the bracket:
Mounting Straps:
Firmly secure the mounting straps to
the Howler by first securing the clamp
mount bracket to the bottom of the
straps using supplied hardware (Fig.
1A). Secure the top of the straps (with
spacer) using supplied hardware Fig.
1B). NOTE: When locating the strap
in the channel provided in the
speaker, slide the speaker all the
way forward as shown here or the
speaker will not line up with the
support bracket when mounted
later.
Main Bracket:
Secure the clamp mount that you secured to the siren speaker in step 1, to the
main bracket as shown in figure 2.
Support Bracket:
Secure the support bracket to the main bracket and siren speaker (Fig. 3).
Mounting to the vehicle:
The photo below shows the bracket mounting location. You will use three
existing bolts from the vehicle (Fig. 4). First remove the 3 bolts from the vehicle
and loosely secure the bracket to stud “C”. Swing the other side of the bracket
up and line it up to the other two mounting studs (A & B). The bracket mounts to
the underside of the lip that bolts A and B go through. Replace bolts A and B and
tighten all bolts securing the bracket to the vehicle.
Extend the WHITE (positive) and BLACK (negative) speaker wires to your siren
amplifier and refer to the amplifiers instructions for connections.
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!
