Mounting:
1. Locate a suitable mounting
location. The vertical wall between
the trunk and the passenger
compartment is often a good
choice and is the method
described in this manual.
2. Be sure that the remote amplifier
fits properly and does not interfere
with any parts of the trunk lid or
seat back.
3. Position the remote amplifier onto
the mounting location. Using an
awl or other suitable tool, scribe
the mounting surface where the
mounting holes are to be drilled.
CAUTION! Mounting the siren will require drilling. It is absolutely
necessary to make sure that no other vehicle components could be
damaged while drilling. If any vehicle component could suffer any
potential harm, select a different mounting location.
4. Carefully drill the mounting holes using a #16 drill bit.
5. Using the supplied #10 x 3/4” sheet metal screws, secure the remote
amplifier to the vertical trunk wall.
Wiring:
Power:
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!
1. Using appropriately sized wire, extend the two (2) RED wires along
the factory wiring harness to the POSITIVE +12VDC battery terminal.
2. Connect the RED wires to one end of a user supplied fuse block.
Do not connect this fuse block to the battery yet.
3. Using appropriately sized wire, extend the two (2) BLACK wires
along the factory wiring harness to the NEGATIVE battery terminal.
Control Switches:
Install two Normally Open Momentary Switches in an area that can be
safely accessed by the operator. One switch will serve as the Activation
Switch. The other will serve as the Cancellation Switch. Refer to the Air
Bag Warning on page 1 before extending any wires into the interior
of the vehicle!
Activation Switch
1. Extend the WHT/BRN and RED/WHT wires to the Activation Switch.
2. Connect the WHT/BRN wire to one side of the Activation Switch
switch and the RED/WHT wire to the other side of this switch.
Cancellation Switch
1. Extend the GRN wire to the Cancellation Switch.
2. Connect the GRN wire to one side of this switch. The other side of
this switch must be connected to Chassis Ground.
or
1. Extend the WHT/GRN wire to the Cancellation Switch.
2. Connect the WHT/GRN wire to one side of this switch. Extend a wire
from the other side of this switch and splice it onto the RED/WHT
wire.
Speakers:
1. Extend the ORANGE, YELLOW and BROWN wires along the factory
wiring harness towards your speakers.
2. Connect the YELLOW wire to the POSITIVE (+) terminal on speaker
#1. Connect the ORANGE wire to the POSITIVE (+) terminal on
speakers #2.
3. Connect the BROWN wire to the NEGATIVE (-) terminal on both
speakers.
Primary Siren Input:
1. Extend the WHT/ORG and WHT/YEL wires to the vehicle’s primary
siren speaker.
2. Splice the WHT/ORG wire onto the positive terminal of the primary
siren speaker.

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!
