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!
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 both siren speakers must face
toward the road after mounting for proper drainage.
1.
This bracket will mount to the vehicle frame behind the front fender
on the driver side. (Fig. 1) First, insert the oval pad of both the
upper and lower bracket into the existing holes in the top and
underside of the frame and secure them to the frame with the
supplied 3/8 - 16 X 4” HEX HEAD BOLT, 3/8” FLAT WASHER and
3/8 - 16 ELASTIC STOP NUT (Fig. 2).
2.
Secure the siren speaker mounting straps to the siren speaker on one side
using the supplied 5/16 - 18 X 1-3/4” HEX HEAD CAP SCREW,
SPACER. 5/16 FLAT WASHER AND 5/16 - 18 ELASTIC STOP
NUT (Fig. 2)
3.
Next slide the other side of the siren mounting
strap around the mounting bracket(s)
(Mounted
to the frame in step 1)
so that the holes in both
line up with the holes in the mounting bracket(s)
and secure the siren straps to the bracket using
the supplied 5/16 - 18 X 1-1/4” HEX HEAD
BOLT, 5/16 FLAT WASHER AND 5/16 - 16
ELASTIC STOP NUT (Two of each) and tighten
firmly (Fig. 2).
4.
Extend the BLACK (-) negative and WHITE (+) positive
speaker wires of both siren speakers to your amplifier and connect
as described in the 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...
