Warnings to Installers
Whelen’s emergency vehicle warning devices must be properly mounted and wired in order to be effective and safe. Read and follow all of Whelen’s
written instructions when installing or using this device. Emergency vehicles are often operated under high speed stressful conditions which must be
accounted for when installing all emergency warning devices. Controls should be placed within convenient reach of the operator so that they can operate
the system without taking their eyes off the roadway. Emergency warning devices can require high electrical voltages and/or currents. Properly protect
and use caution around live electrical connections.Grounding or shorting of electrical connections can cause high current arcing, which can cause
personal injury and/or vehicle damage, including fire. Many electronic devices used in emergency vehicles can create or be affected by electromagnetic
interference. Therefore, after installation of any electronic device it is necessary to test all electronic equipment simultaneously to insure that they operate
free of interference from other components within the vehicle. Never power emergency warning equipment from the same circuit or share the same
grounding circuit with radio communication equipment. All devices should be mounted in accordance with the manufacturer’s instructions and securely
fastened to vehicle elements of sufficient strength to withstand the forces applied to the device. Driver and/or passenger air bags (SRS) will affect the way
equipment should be mounted. This device should be mounted by permanent installation and within the zones specified by the vehicle manufacturer, if
any. Any device mounted in the deployment area of an air bag will damage or reduce the effectiveness of the air bag and may damage or dislodge the
device. Installer must be sure that this device, its mounting hardware and electrical supply wiring does not interfere with the air bag or the SRS wiring or
sensors. Mounting the unit inside the vehicle by a method other than permanent installation is not recommended as unit may become dislodged during
swerving; sudden braking or collision. Failure to follow instructions can result in personal injury. Whelen assumes no liability for any loss resulting from the
use of this warning device. PROPER INSTALLATION COMBINED WITH OPERATOR TRAINING IN THE PROPER USE OF EMERGENCY WARNING
DEVICES IS ESSENTIAL TO INSURE THE SAFETY OF EMERGENCY PERSONNEL AND THE PUBLIC.
Warnings to Users
Whelen’s emergency vehicle warning devices are intended to alert other operators and pedestrians to the presence and operation of emergency vehicles
and personnel. However, the use of this or any other Whelen emergency warning device does not guarantee that you will have the right-of-way or that
other drivers and pedestrians will properly heed an emergency warning signal. Never assume you have the right-of-way. It is your responsibility to proceed
safely before entering an intersection, driving against traffic, responding at a high rate of speed, or walking on or around traffic lanes. Emergency vehicle
warning devices should be tested on a daily basis to ensure that they operate properly. When in actual use, the operator must ensure that both visual and
audible warnings are not blocked by vehicle components (i.e.: open trunks or compartment doors), people, vehicles, or other obstructions. It is the user’s
responsibility to understand and obey all laws regarding emergency warning devices. The user should be familiar with all applicable laws and regulations
prior to the use of any emergency vehicle warning device. Whelen’s audible warning devices are designed to project sound in a forward direction away
from the vehicle occupants. However, because sustained periodic exposure to loud sounds can cause hearing loss, all audible warning devices should be
installed and operated in accordance with the standards established by the National Fire Protection Association.
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.

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 amplifier onto the
mounting location. Using an awl or
other suitable tool, scribe the
mounting surface where the
mounting holes are to be drilled.
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 (Fig. 1).
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. Extend the RED wire
along the factory
wiring harness to the
POSITIVE +12VDC
battery terminal.
2. Connect the RED wire to one end of a user supplied fuse block.
Do not connect this fuse block to the battery yet.
3. Extend the BLACK wire along the factory wiring harness to the
NEGATIVE battery terminal.
Control Switches:
This siren amplifier has six control inputs available. Not all control inputs
will need to be wired depending on the “Mode of Operation” chosen. Five
of the control inputs (CNTRL 1-3, air horn and horn ring) are activated by
applying positive voltage (+VBAT) to them. The RED/WHITE wire (PIN 14)
is a current limited output that can be used for this purpose.The last input
(CYCLE) is activated by applying ground to it (Fig. 2)
A BETA CONTROL HEAD (sold separately) can
also be used to operate the BETA amplifier (Fig. 3).
Speakers:
1. Extend the ORANGE and BROWN wires along
the factory wiring harness towards your siren
speakers.
2. Connect the ORANGE wire to the POSITIVE
(+) terminal and the BROWN wire to the
NEGATIVE (-) terminal of speaker #1.
3. Extend both wires to the POSITIVE and
NEGATIVE terminals of speaker #2 as shown
in the wiring diagram.

Operation:
Siren in use: This output will become active (+VBAT) whenever a tone is
being produced by the siren.
Modes: There are 8 modes of operation. Mode 6 is the factory default
mode. See “Mode Programming” to change the mode of operation.
BETATM1 Controls: Mode 6
Power Switch
This switch has two positions: Down (Beta - Off) and Up (Beta - On).
When this switch is in the Off position, the Beta will not function. When the
switch is in the On position the siren is functional and may be activated.
NOTE: If the Beta is connected to the vehicle’s horn ring circuit, the
vehicle horn is disabled when the BETATM power switch is in the ON
position. The horn ring will now function as a manual siren switch.
Volume Adjustment Screw
The volume adjustment screw controls the volume of the public address
and radio functions and has no effect on siren tones. Volume is increased
by rotating the screw clockwise and decreased by rotating it counter-
clockwise. (See Figs. 1 & 2 for volume control location)
Programming the Siren:
WARNING: Never try to program the siren while it is wired to the ve-
hicle. A low level audio device is built into the siren so siren tones can
be heard during programming.
There are two important operational characteristics of the siren that can be,
re configured; Mode of Operation and Tone Selection. The Scan-Lock™
button is used to select the desired tone changes and the DIP Switches are
used to select Mode of Operation. The Scan-Lock button can be activated
with a pen or similar object. (See Fig. 1 for Scan-Lock™ button location)
Siren Tone Programing Procedures:
With Scan-Lock™ the tonal operation of the siren can be customized
to fit your needs. Scan-Lock™ is used to change the default siren
