IMPORTANT! READ 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!
2. Secure the Howler siren
speakers to the mounting
brackets using the supplied
sheet metal screws. Mount
the speaker so the screened
vent holes are facing down
toward
the
road
after
mounting.
NOTE: The serial number on
the mounting brackets will
end in a “D” for driver side or
“P” for passenger side.
IMPORTANT:
The
slotted
holes in the siren speaker
must face toward the road
after mounting for proper
drainage.
3. Mount the bracket to the
frame using the supplied
hardware (Fig. 2).
4. Remount the skid plate you
removed in step 1. One of
the bolts that held the skid
plate on will be used to mount the bracket on both sides.
5. Extend the WHITE (positive) and BLACK (negative) speaker wires to
your siren amplifier and refer to the amplifiers instructions for
connections.
