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.

Mounting...
An aftermarket center console is recommended for the mounting location. This not only allows the driver to reach the controls easily, but also
keeps the unit safely out of the path of the vehicle’s SRS air bag. Follow the console manufacturer’s instructions for mounting information. If a
console mounting is not possible, a bail strap mounting kit for over or under dash mounting is included. The following steps will guide you through
the installation process.
Wiring...
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!
Power Wires (Heavy Gage Wires)
1. Extend the 2 heavy gage RED wires along the vehicle factory wire harness towards
the battery. It may be necessary to drill a hole in the firewall. If so, be absolutely sure

Terminal Operation...
The unit contains 15 screw terminals located in the upper rear panel of the housing. These terminals have been designed to activate components
that do not exceed specific load ratings (current draw). It is important that any components connected to these terminals do not exceed the
maximum current rating for that terminal. The terminals are rated as follows:
Terminal #’s Max. Load Fuse Designation
#1 20 Amps F1
#2 20 Amps F2
#3, #4 & #5* 20 Amps (Total) F3
#6 10 Amps F4
#7 10 Amps F5
#8 10 Amps F6
#9 10 Amps F7
#11** 10 Amps
#12 10 Amps F8/F8A
#14** 10 Amps
#15 10 Amps F9/F9A
* Terminals #3, #4 & #5 can not be individually activated.
** Terminals 11 & 14 are always on unless otherwise noted.
Dip Switches...
In the default dip switch/fuse configuration the terminal outputs are enabled as follows:
Slide Switch Positions - Push-button Switches -
0 = Terminals OFF 4 = Terminal #6 ON
1 = Terminal #1 ON 5 = Terminal #7 ON
2 = Terminals #1 & 2 ON 6 = Terminal #8 ON
3 = Terminals #1, 2, 3, 4 & 5 ON 7 = Terminal #9 ON
8 = Terminal #12 ON / Terminal #11 OFF
9 = Terminal #15 ON / Terminal #14 OFF
See the “Custom Dip Switch Configurations” section for information on changing default
terminal control
Custom Dip Switch Configurations (Bank 1):
Slide Switch Functionality
In the default configuration the slide switch controls terminals 1 thru 5 (see the Term ina l
Specifications section for details). This configuration can be altered so that any
combination of these five terminals may be active or inactive in any of the 3 functioning
slide switch positions. The slide switch configurations are controlled by a dip switch bank
which is located on the top circuit board. Access is gained by removing 4 Torx-head
screws located at the 4 corners of the face plate. With these screws removed, slide the
chassis housing cover towards the rear of the unit. It is not necessary to slide this cover
more than a few inches, as the dip switch banks are located behind the control panel.
To help illustrate how to change default slide switch control, the following will outline how
configure the slide switch so that in position 2, only terminal 2 is enabled, while position 3
will only enable terminal 3.
SLIDE SWITCH POSITION 1 is controlled by dip switches 1, 2 & 3 on bank 1. Dip switch
1 (which controls Terminal 1) is in the on position, while dip switch 2 (which controls
Terminal 2) & dip switch 3 (which controls Terminals 3, 4 & 5) are in the off position. This
means that when the slide switch is in position 1, Terminal 1 alone becomes active.
SLIDE SWITCH POSITION 2 is controlled by dip switches 4, 5 & 6 on bank 1. Dip switch
4 (Terminal 1) is off, dip switch 5 (Terminal 2) is on and dip switch 6 (Terminals 3, 4 & 5) is
off. This means that when the slide switch is moved to position #2, Terminal 2 alone is
active, while Terminals 1, 3, 4 & 5 are inactive.
SLIDE SWITCH POSITION 3 is controlled by dip switches 7, 8 & 9 on bank 1. Dip switch
7 (Terminal 1) is off, dip switch 8 (Terminal 2) is off and dip switch 9 (Terminals 3, 4 & 5) is
on. This means that when the slide switch is moved to position 3, Terminals #3, 4 & 5 are
active, while Terminals 1 & 2 are inactive.
Enabling Siren Tones through Slide Switch Position #3: Slide switch position 3 can be configured to automatically activate siren tones, as
described in Rotary Switch Operations. If this is not desired, make sure that Dip Switch 1 on Bank 2 is in the OFF position. Please note that siren
activation through Slide Switch Position 3 is only available when the power switch is in the ON position.

Custom Dip Switch Configurations (Bank 2):
Push-button 9 (a momentary-type switch) has the ability to function in four different
modes. These modes are defined by the five-position dip switch (Bank 2).
Mode 1 (default) - In this configuration, the output is activated for as long as push-button 9
is depressed.
Mode 2 - In this configuration, when push-button 9 is pressed, the output is activated for a
period of 8 seconds.
Mode 3 - In this configuration, when push-button 9 is pressed, the output is activated.
When pressed again, the output is deactivated.
Mode 4 - In this configuration, when push-button 9 is pressed, the output is activated for a
period of 400 ms. After 400 ms, the output is deactivated for 400 ms. This cycle will
continue until push-button 9 is pressed again.
Custom Fuse Configurations:
Push-buttons 8 & 9 Functionality
Terminals #10 & 13 do not function as output terminals and are not used in the default configuration.
By changing the positions of specific fuses, these terminals can be configured to control auxiliary
circuits. These auxiliary circuits can not exceed 10 amps each.
Moving Fuse #8 from its default position (F8) to its optional position (F8A) allows push-button 8 to
control an auxiliary circuit. Connect Power In from the aux. circuit to Terminal #10 and Load Out to
Terminal #12. Push-button 8 will now open and close this circuit.
Moving Fuse #9 from its default position (F9) to its optional position (F9A) allows push-button 9 to
control an auxiliary circuit. Connect Power In from the aux. circuit to Terminal #13 and Load Out to
Terminal #15. Push-button 9 will now open and close this circuit.
Backlighting
Backlighting for the six push-buttons may be controlled in one of two manners: In the default (as
shipped) mode, the 3-position connector controls the backlighting. The WHITE/YELLOW wire may be
connected to a 12VDC source that is activated with the vehicle’s ignition switch. For vehicles utilizing
a battery disconnect switch an internal jumper may be moved, allowing the backlighting to be
controlled by power applied to the number 10 AWG input wires, saving an additional connection.
Diagnostic Indicators
The unit has two diagnostic indicators on the front panel which are used to indicate fault conditions
with your siren system. The following table lists the type of fault and the indicators response. If the
indicator is on steady while a tone is in use, this implies that there is no fault with the associated
speaker output.
Fault Condition and Diagnostic Indicators Response
Over Voltage -
Speaker LED #1 will be in a DoubleFlash mode (2 quick flashes followed by a pause).
Under Voltage -
Speaker LED #2 will be in a DoubleFlash mode (2 quick flashes followed by a pause).

POWER SWITCH
This switch has two positions: Down (Off) &
Up (On). When this switch is Off, the unit will
not function. When the switch is On, the siren
is functional and may be activated at the
operator’s discretion.
ROTARY SWITCH
The Rotary Knob controls the Radio Repeat
and PA (Public Address) functions of the unit.
VOLUME KNOB
The Volume Knob controls the volume of
Public Address function. Volume is increased
by rotating the knob in a clockwise direction.
Rotating the volume knob in a counter-
clockwise direction decreases the volume
produced by these features.
RADIO REPEAT VOLUME
Before use, the Radio Repeat output volume
must be adjusted to satisfactory operating
levels. To adjust this level, a small, flat-blade
screwdriver is needed. Locate the Radio
Repeat adjustment port (potentiometer) to
the right of the Rotary Knob on the face of the
control head. Set the volume level of the
vehicle’s two-way radio to its normal operat-
ing volume. Turn the Rotory Knob on the con-
trol head to RAD to activate Radio Repeat.
Insert the screwdriver in the Radio Repeat
adjustment port and turn in clockwise direc-
tion to increase the sound level.

Rotary Switch Operations:
RAD (Radio Repeat) - When the rotary knob is in the RAD position,
any signal that is received by the vehicle’s two-way radio will be
simultaneously broadcast over the vehicle’s loudspeaker (the unit
must be connected to the two-way radio as outlined in this manual).
When the rotary switch is in any other position, the siren is in a
standby state where no tones have been activated, but is waiting for
another action to be taken by the operator. These positions are the
best choice when public address is required.
Microphone
Whenever the unit is powered on, activating the microphone (pressing
the switch on the side of the mic.) will shut down any other siren
functions and enable public address operation regardless of the rotary
switch position or any other switch or input.
