500 Series Control System and Siren Amplifier
ENGSA5(xxxSx)
Rev. D - 07/2021
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.

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.

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.

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
