SIREN SYSTEM NOTICE
Sirens provide an essential function of an effective audio / visual
warning system and are required in most states for emergency
vehicles operating under statutory exemptions.
However, sirens are only short-range secondary devices. The use of
a siren does not ensure that all drivers can or will abide by or react
to an emergency warning signal, especially at high rates of speeds
or long distances. The operator of the vehicle must never take the
right of way for granted, and it is the operator’s responsibility to
proceed safely.
The reliability and effectiveness of this siren system is highly
dependent on the correct mounting and wiring. The installer must
read and follow the manufacturer’s installation instructions and
warnings in the manual. The vehicle operator should routinely verify
that the siren system is securely fastened to the vehicle and properly
functioning.
Effective sirens generate loud sound pressure levels that can
potentially cause hearing damage. Installers and those around the
vehicle need to be aware of these dangers and wear hearing
protection whenever the siren system is operating. Vehicle operators
and occupants should assess their exposure to siren noise and
determine what steps need to be taken to prevent hearing damage.
The siren system is intended for use by authorized personnel only. It
is the user’s responsibility to ensure they understand and operate the
emergency warning devices in compliance with all applicable city,
state, and federal laws and regulations. SoundOff Signal assumes no
liability for any loss resulting from the installation and use of the siren
system.
CAUTION & NOTICE TO THE INSTALLER
Make sure to read and understand all instructions and warnings
before proceeding with the installation of this product. Ensure the
manual and all warning cards are delivered to the end-user of this
equipment. It is your sole responsibility to install this product in
accordance with known automotive electrical best practices. Vehicle
modification is done at the sole risk of the modifier and should follow
vehicle manufacturer guidelines.

See the image above. Connect 12 VDC power directly to the screw-
down block on the upper control board inside the siren (left side of
image). Use a 1/8” Allen/hex wrench and torque to the
recommendation shown on the table to the left. There is a provided
pass-through hole in the siren for routing this power circuit into the
siren, labeled CN1 on the back cover. When making the connection,
be sure to use either of the included wire ferrules to provide a tight
and secure connection.
NOTICE: WIRE FERRULES MUST BE USED. DO NOT TIGHTEN THE
BLOCK ON BARE WIRE.
We recommend crimping the ferrules using the manufacturer
recommended crimpers (SQ28-10 or TRAP24-10) or equivalents.
The chart on the next page shows the recommended ferrule size for
the supply circuit size as well as the recommended wire gauge for
various amperage loads. This circuit supplies power for all the solid-
state and internal relays (CN2, CN4, CN5 & CN6). The upper control
board is rated for no more than 75A total. When fusing, use a fuse
rated for 125% of the total switched current in your application
PLEASE NOTE: The wire and ferrule combination determine the
maximum amperage throughput for the connection, based on ferrule
to wire surface contact. These ratings are recommended by the
connector manufacturer.
NOTICE: TO PREVENT STRAIN ON ALL CONNECTORS AND TO
ALLOW FOR EASE OF FUTURE SERVICEABILITY, WE RECOMMEND
INSTALLERS LEAVE SUFFICIENT EXTRA LENGTH OF WIRE TO
PROVIDE A SERVICE LOOP. THIS SERVICE LOOP SHOULD BE
SECURED TO THE INSTALLATION PLATFORM OR A TIE DOWN
POINT.

ENGSA5(xxxSx)Rev. D - 07/2021
Siren Amplifier Power, Ground, and Fusing
CN12.1 and CN12.2 are for the siren amplifier power and ground. The
siren amplifier is externally fused on the back panel, with either a 15A
or 25A fuse for 100/200 watt systems.
In addition, we recommend fusing the power circuits to protect the
wiring between the power source and the siren amplifier itself –
unless the amp is within 18” of the power source.
For CN12.1, we recommend fusing the power circuits at 15A for
100w siren systems and 25A for 200w siren systems.
Route CN12.2 to the vehicle’s chassis, preferably to a factory
grounding point. We do not recommend grounding with a self-
tapping screw.
Internal Relay Fuses
There are seven internal fuses for the various relays on the 500
Series Control System which are all user-serviceable. Please see the
diagram on page 3.
SYSTEM OUTPUTS
CN2 - 20A High Current Relay Outputs
Each of the outputs on connector CN2 is rated for 20A. The relay
outputs are capable of constant steady power. These outputs can be
paralleled where necessary.
NOTE #1: The total current for these three outputs should not exceed
50A.
NOTE #2: There is a connector material change from tin to gold
connectors as of Jxxxxx. Units produced after
this date (numerically higher) use gold terminal
connections. Units produced before this date
(numerically lower) use tin terminal
connections. Do not mix gold and tin terminal
connections.
CN5 & CN6 - 10A High Current Relay Outputs
CN5.1 – CN5.3 and CN6.1 – CN6.3 contain input
and output wires for relay outputs 1 and 2. For
each relay, there are three connections:
• Pins 1 & 2 – Normally Open (1), and
Normally Closed (2) outputs. The resting (off)
state for this relay is Normally Closed (2) being
active, and Normally Open (1) being inactive.
• Pin 3 – External Input. Pins 1 & 2 can be
provided external power or ground using this
input. This does require moving an internal fuse,
as shown on page 3.
Please Note: When using the above outputs for
inductive loads that utilize a coil - such as
external relays, gun locks, solenoids, or electric
motors, we advise installing a shunt diode at the
device to suppress transients/reverse voltage
during shutdown of the circuit. This is shown on
page 14. This diode should be rated at a
minimum of 100v at 1a.
CN4, CN5 & CN6 - Solid State Programmable
Outputs
Connectors CN4, CN5, and CN6 have five solid-
state outputs on each connector for outputs 1-15. These are on pins
4-8 on each plug.
Through SoundOff Central bluePRINT programming software, each
output’s on, and off-state as well as flash patterns, can be prioritized
and programmed. Additionally, each output’s amperage shut-off
threshold can be adjusted up to the 5 and 10A limits.
Each of the outputs provides diagnostic information to bluePRINT to
aid in troubleshooting should it be needed at a later date. The output
circuits and amperage limits are shown on the schematics on page
9.
Each connector has an output that is diode isolated (pin 5), and an
output that allows for inrush (start-up) surging (pin 6). These are
detailed on the schematics, shown on page 9.
To aid in installation, a silver wire label sheet for connectors CN4 -
CN6 is included with the 500 Series Control System. The wire labels
can be used to mark each harness and where it is connected. There
is space on each label for the upfitter to provide additional
information as needed.
LIGHTBAR CONTROL BUSES
CN3 – RJ-45 - Lightbar Data Bus #1 – RJ-45 Direct Connect
The 500 Series Control System has internal and external lightbar
controls meaning it can be used with or without a Breakout Box
(B.O.B). This allows for direct connection (with no B.O.B.) using the
nFORCE® Exterior Lightbar, or any of SoundOff Signal’s three-wire
type lightbars using an RJ-45 to single wire adapter (shown on page
12).

*The is the maximum amount of current the wire
ferrule can transfer.
•Always use both the ferrule and rubber wireguard.
•Inspect for stray strands that could cause a short
circuit. Verify strands do not protrude more than 4mm
(.15”) beyond lug.
•Always consult wiring standards for specific
application, wire type, and ferrule size.
•Always use the recommended lug torque. When
torquing, we recommend holding torque pressure for 5
seconds, to aid in torque stability. DO NOT USE
THREADLOCKER.
•Always size wire to allow for 125% of current.
•Do not solder wires to be used in the lug. This can cause
loosening over time.

This port also supports connecting multiple external B.O.B.’s using
parallel CAT-5 splitters. This feature can be programmed through
SoundOff Central bluePRINT software.
When using more than one external B.O.B., parallel splitters may be
necessary. Any parallel splitter will work to provide extra RJ-45
connection points.
Please note – Crossover splitters, Ethernet Routers, and Ethernet
Switches are not the same thing as a parallel splitter and will cause
data transmission problems.
Lightbar data bus #1 and #2 can be controlled independently.
CN4.3 – Lightbar Data Bus #2 – Single Wire Direct Connect
A second lightbar channel is provided for connecting an additional
data controlled lightbar (mpower®, nFORCE® Interior Lightbar,
nFUSE®). No B.O.B. is needed for this connection. Through SoundOff
Central bluePRINT programming software, lightbar data bus #1 and
#2 can be controlled independently.
Lightbar Data Bus Connectivity
See the data bus connectivity schematic on page 12.
CONTROL PANEL BUS #1 (REMOTE) & OPTIONAL EQUIPMENT
Control Panel Bus #1 is located on the rear panel of the siren
amplifier. It is designated CN11.
CN11 – RJ-45 – Remote Control Panel
When using a remote mounted control system, connect the remote
control panel here using a standard Ethernet patch cable (not cross-
over). Alternately, if using a console-mounted system, a secondary
control panel can be connected here.
CN11 – RJ-45 – bluePRINT Link®
bluePRINT Link is an add-on component for bluePRINT that passively
scans the host vehicles CANBUS for data signals that can be utilized
in programming. bluePRINT Link connects to the CN11 RJ-45 port, or
it can connect to the control panel itself provided it is on the Control
Panel Data Bus / Remote Control Panel Bus (as shown on page 12).
See the bluePRINT Link installation guide for more information.
CN11 – RJ-45 – bluePRINT Sync®
bluePRINT Sync is an add-on component for bluePRINT that keeps all
equipped vehicles in perfect synchronization of flash patterns.
bluePRINT Sync connects to the CN11 RJ-45 port, or it can connect
to the control panel itself provided it is on the Control Panel Data Bus
/ Remote Control Panel Bus.
See the bluePRINT Sync installation guide for more information.
CN11 – RJ-45 – Using Parallel CAT-5 Splitters
Between the Control Panel, bluePRINT Link, and bluePRINT Sync,
parallel splitters may be necessary. Any parallel splitter will work to
provide extra RJ-45 connection points.
Please note – Crossover splitters, Ethernet Routers, and Ethernet
Switches are not the same thing as a parallel splitter and will cause
data transmission problems.
CN11 – RJ-45 – Control Panel Databus Connectivity
See the data bus connectivity schematic on page 12.
CONTROL PANEL BUS #2 (CONSOLE) / SIREN DATA BUS
Front Side / Board Mounted RJ-45 – Console or Remote Control
Panel (Siren Bus)
Console mount siren amplifiers have connectivity between the
Control Panel and the siren amplifier using a short Ethernet patch
cable (not cross-over) at the front of the amplifier (internal). When
using a remote mount siren amplifier, a secondary panel can be
connected to this port to provide further system control.
Control Panel Bus #2 / Siren Data Bus Connectivity
See the data bus connectivity schematic on page 13.
SYSTEM INPUTS
CN4.1 – CN 4.2 - Horn Ring Circuit
Connections CN4.1 and CN4.2 operate the horn signal function for
the OEM horn. When active, the horn signal will not pass through to
the OEM horn, and instead will be processed by the 500 control
system.
CN4.2 is connected to the horn ring signal (from the vehicle horn
circuit). CN4.1 is the output, returning back to the horn ring circuit.
SoundOff Central bluePRINT software allows custom programming of
when the horn ring is active as well as additional function based on
horn ring sense. In the software, CN4.2 is referred to as “Horn Ring
Sense,” and this is mapped by default in new programs to the Horn
Ring Secondary Trigger output.
Additionally, the Ignition input (CN7.1) is mapped by default to the
“Horn Ring Rules Enabled” output. When active, these rules allow
bluePRINT to process horn ring input functionality.
High Current Horn Ring - When routing a positive horn ring through
the horn ring cut circuit, the input and output amperage should be
limited to 5A. If exceeding 5A, please use an external relay to handle
the amperage as shown in the image on page 11. This requires an
output to trigger the relay when horn ring transfer is desired.
CN7.1 – System Ignition Input
This is the primary ignition input for the 500 Series Control System.
This input controls when the system turns on and when it goes into
the system shutdown timer state.
Through SoundOff Central bluePRINT programming, the system can
be set to stay active for a specified time after ignition shut down –
up to 18 hours. Additionally, any outputs that are activated by
ignition can also be programmed to remain active independently for
a specified time frame.
As an alternative, Input #1 on any remote node or Input #12 on the
Input Node can be set to wake up the bluePRINT system. This needs
to be programmed using SoundOff Central bluePRINT Software.
When connecting ignition to this circuit, it should be fused at 3A.
CN7.3 - CN 7.6 - Pulse Width Modulation Inputs
Inputs CN7.3 – CN7.6 average the input signals allowing them to
work with Pulse Width Modulation (PWM) more efficiently. This

feature needs to be activated in the SoundOff Central bluePRINT
Software. It is not on by default.
Vehicle OEM’s typically use pulse width modulation frequencies from
100 to 250 Hz.
PWM is measured in Duty Cycle - referring to “on” time in each
cycle. Below is an example of different common duty cycles.
Vehicle manufacturers commonly use PWM to control vehicle
brightness, including headlights, parking lights, and interior lights.
CN7.2 - CN7.9 - Discrete Inputs 1-8
Through SoundOff Central bluePRINT Programming, each of these
inputs can be customized and mapped to control different outputs.
All of these inputs can be set to high polarity (positive), or low
polarity (ground).
System Siren Functions
CN8 – Siren Speaker Outputs
The Orange and Orange/Black wire pair is the primary speaker (A)
output on a 100 or 200-watt system. For 200-watt systems, the
Green and Green/Black speaker outputs drive the secondary speaker
(B). When extending the wiring to the siren speaker, use a minimum
of 16ga wiring.
Please note: There is no polarity requirement for these outputs. Either
output can be considered positive or negative.
CN9.3 & CN 9.6 – Radio Rebroadcast
The two blue wires on CN9 are reserved for Radio Rebroadcast
functions. Radio rebroadcast allows the siren amplifier to broadcast
radio transmissions through the siren speaker. Radio Rebroadcast
will not work if the signal is driving remotely amplified speakers,
since the signal amplitude is likely too low.
Locate the two wires that connect the external speaker to the two-
way radio. Splice one blue wire into one of the external speaker
wires. Splice the other blue wire into the other external speaker wire.
If the blue wires need to be extended, use a minimum of 20ga wire.
Radio Rebroadcast Volume
Radio Rebroadcast volume must be adjusted before placing the
vehicle into service. Volume can be set through the SoundOff Central
bluePRINT Software.
PA Microphone
The PA Microphone in bluePRINT is a specialized high gain
microphone that connects via a 1/4” TRS (Tip/Ring/Sleeve) audio
jack on the front of the control panel.
12v Input @ 100% Duty Cycle - Signal is never off.
12v Input @ 75% Duty Cycle - Signal is off 25% of the time.
12v Input @ 50% Duty Cycle - Signal is off 50% of the time.
Microphone to the control panel isn’t desirable. As an optional
installation, the PA Microphone can be connected directly to the
siren amplifier, using accessory kit PSRN5HDK3.
The accessory kit includes a 20’ TRS audio cable, an additional
microphone jack and an internal adapter cable, allowing the
microphone to be removed from the control panel, and connected
directly to the siren amplifier.
On pages 12 and 13 is an example of both types of installations.
PA Volume
PA volume is set using SoundOff Central bluePRINT Software.
PROGRAMMING
CN10 - USB Port
All programming for bluePRINT is performed through this port.
Connected lightbars can also be configured through this port.
Programming & Troubleshooting
SoundOff Central bluePRINT Software allows for programming of
bluePRINT.
DEFAULT FUNCTIONALITY
Although we anticipate the 500 Control System will be custom
programmed either by the upfitter or the end-user, it does contain
default functionality that provides operation similar to the 400 series
siren amplifier.
These defaults are erased the first time a program is uploaded to the
500, and they are not recoverable.
This information is covered in the 500 Control System Defaults
Addendum, which is available through the Dealer Portal.
WIRE AMPERAGE TABLE
NOTICE:
• These figures are calculated assuming battery voltage at 12.8
VDC. This accounts for equipment that may be running with the
engine off.
• Don’t forget the wire length accounts for the total length of the
circuit - from power supply through the load device to ground
termination.
• This table was calculated with a target voltage drop at 2% or less.

LIN Bus connections include Remote Nodes and Input Nodes. These can be
connected using the same wire, connected in parallel, or by using junction
points as shown below.
Input Nodes are only necessary when using additional discrete inputs beyond
the eight provided inputs from the 500 Series Control System.
A lightbar breakout box can be configured as an alternate input node. Lightbar
B.O.B.s cannot be connected here and must be connected as shown on page

* BUILDING AN RJ-45 TO THREE
WIRE CONTROL ADAPTER
Using a standard RJ-45 Connector
and a short length of CAT-5 cable,
insert the blue pair of wires into
pins #4 and #5 and then crimp
the plug. This is very similar to
building an Ethernet cable but only
the blue pair is necessary.
Connect both of those wires to the
lightbar data wire.

Inductive loads are a type of electrical load found in
devices that convert electrical current into a
magnetic field. In electronics, this covers just about
any device that utilizes a coil.
One of the characteristics of inductive loads is how
it stores energy from when it is switched on. This
energy store is often referred to as reactive power.
When the inductive load is shut down, this reactive
power is converted into stray voltage. Per the laws
of electricity, this stored energy must dissipate
when the load is switched off.
As a result of this characteristic, inductive loads can
cause transients or “spikes” at the moment of
shutdown.
To protect equipment against these spikes, we
strongly recommend installing a shunt diode as
shown on the diagrams to the left. The left diagram
shows how to wire the shunt diode in a positive
switched circuit, and the right diagram shows the
same for a ground switched circuit.
A shunt diode is nothing more than a standard diode
that allows the leftover voltage to dissipate. We
recommend a diode that is rated at least 100v at 1a.
In the emergency and utility vehicle industries,
inductive loads cover installing any of the following
devices (but are not limited to):
• Gun Locks
• Solenoids
• Relays
• Fans
• Motors
• Pumps
