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!
CAUTION
Loud siren noise can cause
hearing damage and/or loss.
Refer to OSHA Section 1910.95 prior

Safety First
This document provides all the necessary information to allow your Whelen product to be properly and safely installed.
Before beginning the installation and/or operation of your new product, the installation technician and operator must
read this manual completely. Important information is contained herein that could prevent serious injury or damage.
• Proper installation of this product requires the installer to have a good understanding of automotive electronics,
systems and procedures.
• If mounting this product requires drilling holes, the installer MUST be sure that no vehicle components or other
vital parts could be damaged by the drilling process. Check both sides of the mounting surface before drilling
begins. Also de-burr any holes and remove any metal shards or remnants. Install grommets into all wire
passage holes.
• If this manual states that this product may be mounted with suction cups, magnets, tape or Velcro®, clean the
mounting surface with a 50/50 mix of isopropyl alcohol and water and dry thoroughly.
• Do not install this product or route any wires in the deployment area of your air bag. Equipment mounted or
located in the air bag deployment area will damage or reduce the effectiveness of the air bag, or become a
projectile that could cause serious personal injury or death. Refer to your vehicle owner’s manual for the air bag
deployment area. The User/Installer assumes full responsibility to determine proper mounting location, based
on providing ultimate safety to all passengers inside the vehicle.
• For this product to operate at optimum efficiency, a good electrical connection to chassis ground must be
made. The recommended procedure requires the product ground wire to be connected directly to the NEGATIVE
(-) battery post.
• If this product uses a remote device to activate or control this product, make sure this control is located in an
area that allows both the vehicle and the control to be operated safely in any driving condition. DO NOT
ATTEMPT TO ACTIVATE OR CONTROL THIS DEVICE IN A HAZARDOUS DRIVING SITUATION.
• It is recommended that these instructions be stored in a safe place and
referred to when performing maintenance and/or reinstallation of this

The Power Airhorn™, like all Whelen components, can be installed in many
different types of vehicles. The guidelines for the installation of this product
are written so that no matter what vehicle is being used, the installation and
operation will be simple and straight forward.
Selecting a Mounting Location . . .
The most common choice for a mounting area would be a trunk or
similar compartment. However, due to the wide variety of vehicles
onto which the airhorn amplifier can be installed, this is not always
possible. The following guidelines will help you select an acceptable
alternative:
A) The Power Airhorn should be mounted on a metal surface to
aid heat dissipation. Be sure that this surface is not one that
either generates or is exposed to excessive heat during nor-
mal operation of the vehicle.
B) Do not select a location where the unit will be exposed to
potential damage from any unsecured or loose equipment in
the vehicle.
C) Be sure the area selected will not allow the amplifier to be
exposed to water!
D) When routing the unit’s wires, it is important to choose a path
that will keep these wires away from excessive heat and from
any vehicle equipment that could compromise the integrity of
the wires (ex. trunk lids, door jams, etc.).
E) When the best mounting location has been determined,
securely fasten the unit to its mounting surface using the sup-
plied hardware.
Caution: As it will be necessary to drill holes into the mounting surface, the
installer MUST be sure that no vehicle components or other vital parts could
be damaged by the drilling process. Check both sides of the mounting
surface before drilling begins!
1. Position the amplifier in its proposed mounting location to ensure that it fits
properly. With the unit in place, insert an awl or other suitable tool into the
mounting screw area of the unit and scribe the areas that are to be drilled.
2. Remove the unit from its mounting area and, using an appropriately sized
drill bit, drill a hole in each of the areas scribed in the previous step.
3. Return the unit to its mounting location and using the supplied
screws, mount the unit onto its mounting surface.
Wiring . . .
Wire the unit as shown in the diagrams.
WARNING: All customer supplied wires that connect to the positive
terminal of the battery must be sized to supply at least 125% of the
maximum operating current and FUSED at the battery to carry that
load. DO NOT USE CIRCUIT BREAKERS WITH THIS PRODUCT!
NOTE! Although a 10 amp fuse (customer supplied) is required to
be used in the fuse block, do not install the fuse until all of the wire
connections are completed.
