DANGER! Sirens produce extremely loud emergency warning tones! Exposure to these 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!

a console or other location. Using the measurements
below, cut the hole for the control head, then slide the
unit in. Mark and drill the four mounting holes for the
customer supplied mounting hardware.

Important: Mounting will require drilling. It is absolutely necessary
to make sure that no vehicle components behind the mounting area
will be damaged. If damage is possible, Select another location.

Installation: There are two mounting styles for the
siren control head depending on the model purchased.

Bail Strap Mount: isTh unit uses a bail strap that can
be attached under the dash. Follow the diagram above for assembly
of the bracket. You will need to supply the screws that attach the
bracket to the vehicle.

Installation: Amplifier

1. Locate a suitable mounting location for the amplifier. The vertical wall
between the trunk and the passenger compartment is often a good
choice and is the method discussed in this manual.

2. Be sure that the amplifier fits properly and does not interfere with any
parts of the trunk lid or seat back.

3. Position the amplifier on the proposed mounting location. Using an
awl or other suitable tool, scribe the mounting surface where the
mounting holes are to be drilled.

CAUTION! As mounting the amplifier will require drilling, it is
absolutely necessary to make sure that no other vehicle components
could be damaged by the drilling process. If any vehicle component
could suffer any potential harm, select a different mounting location.

4. Carefully drill the mounting holes using a drill bit sized for a #10 sheet
metal screw.

5. Using the supplied #10 x 3/4” sheet metal screws, secure the remote
amplifier to the vertical trunk wall.

Wiring

Connecting to Power:

1. Using appropriately sized wire, extend the RED and BLACK wires
from the Main Power Connector, through the firewall and into the
engine compartment (refer to the Wire Gage Calculation Chart
located on the last page of this manual to determine the proper wire
size for your application).

2. Follow the factory wiring harness towards your vehicle’s battery.

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
load. DO NOT USE CIRCUIT BREAKERS WITH THIS PRODUCT!

3. Install a user supplied 20A fuse block on the end of the RED wire.
Connect the fuse block to the battery using no more than 2 feet of
wire. Do not install the fuse into the fuse holder yet!

at the battery to carry that

4. Connect the BLACK wire directly to the NEGATIVE battery terminal.

Connecting to your Speaker(s):

1. Route the ORANGE, and BROWN wires from both Siren Connector
#1 and Siren Connector #2 along the factory wiring harness towards
your speakers.

2. Connect the ORANGE wire from Siren Connector #1 to the
POSITIVE (+) terminal on speaker #1. Connect the ORANGE wire
from Siren Connector #2 to the POSITIVE (+) terminal on speaker
#2.

3. Connect the BROWN wire from Siren Connector #1 to the
NEGATIVE (-) terminal on speaker #1. Connect the BROWN wire
from Siren Connector #2 to the NEGATIVE (-) terminal on speaker
#2.

Hands-Free Siren (optional):

Refer to the wiring diagram for all wiring information for this optional
connection.

Radio Rebroadcast (optional):

The two (2) BLUE wires are used to connect your two-way radio’s external
speaker for radio rebroadcast. This is an optional connection and will not
effect the other operations.

Note: Radio rebroadcast will NOT work with amplified remote
speakers! If your remote speaker is amplified (I.E.: contains a power
amp circuit in the speaker assembly), do not enable the radio
rebroadcast feature.

Installation will be complete after a 20A fuse has been installed in the Main
Power Connector fuse block. Now inspect the fuses at the back of the
amplifier and at the battery. If either of these fuses are blown, carefully
inspect all of the circuit wires and make sure they are wired correctly.
Replace the blown fuses with ones of an identical amp rating. If these
fuses blow after installation or activation, contact Whelen Engineering
Technical Support.
