500 Series Control System and Siren Amplifier
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.

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.

USES
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.
