each connector position to secure the wires in the
connector.
e.
As supplied in the kit, insert a 25-
ampere fuse in the fuse holder in the back of the
Amplifier unit.

LED.
a.
Unless previously routed, route
the SignalMaster cable toward the Amplifier Unit.
Use caution to avoid scraping the wires on any sharp
edges.
b.
Cut the cable to the appropriate
length as required.
c.
Route user-supplied black 14-
gauge wire through the firewall and toward the
battery. Route the user-supplied red 14-gauge wire
toward the ignition terminal. Connect the red wire to
one end of the supplied 25-ampere circuit breaker
(Part No. 152118-25). Do not connect the other end of
the circuit breaker to the ignition terminal until ALL
wiring is complete.
d.
Strip 1/4" of insulation off each wire
at the eleven-position connector end. Insert the eight
22-gauge wires, the 16-gauge red wire, and the 14-
gauge red and black wires into the connector as
shown in figure 3-13 and figure 3-12. Tighten the
screw at each connector position to secure the wires
in the connector.
e.
As supplied in the kit, insert the
appropriate fuse (25-ampere for LED SignalMasters
or 7.5-ampere for Cuda TriOptic™, 6 or 8 module) in
the fuse holder in the back of the Amplifier unit.
D.
Control Head Connections.
All connections between the SS2000-LMS
control head and Amplifier Unit are accomplished by
a single 20-foot telephone-type cable (provided). It is
terminated with modular-type connectors on each
end.
CAUTION
The unit will not operate if the telephone-type
cable is improperly wired. If it is necessary to
shorten the 4 conductor telephone-type cable,
ensure that the connections made to the
modular connector are exactly the same as the
original cable connections.
To complete this portion of the installation,
proceed as follows:
1.
Route the 20-foot cable between the
SS2000-LMS control head and the Amplifier Unit.
Secure the cable with user-supplied clamps and hold
downs as required.
2.
Insert the modular connector in the
receptacle on the back of the SS2000-LMS Amplifier
Unit. Secure with user-supplied clamps and/or wire
ties to provide strain relief.
3.
Insert the other modular connector in
the receptacle on the control head. Secure with user-
supplied clamps and/or wire ties to provide strain
relief.
E.
Microphone Connections.
The SS2000-LMS is not supplied with a
microphone. A Federal Model MNCT-SB microphone
may be plugged into the microphone jack on the rear
of the Amplifier Unit.
If the Amplifier Unit is remotely mounted,
Model RMK (microphone extension kit) is available
from Federal. It includes a 20- foot extension cable
with phone plug, jack, and dashboard mounting
bracket.
Carefully route the extension cable through
the vehicle along with the telephone-type cable, and
secure with user-supplied clamps and ties as re-
quired.
The SS2000-LMS also provides common
microphone capability. Use the Federal Signal
common microphone module to connect a common
microphone such as the GE radio microphone. See
figure 3-6 to connect the "common microphone
enable" to the common microphone module.
3-7. INSPECTION AND FINAL INSTALLATION.
A.
See figure 3-2. Secure the SS2000-LMS
Amplifier Unit to the mounting bracket with the
BLACK 1/4-20 x 1/2 hex head screws and 1/4 split
lockwashers. Ensure all fasteners are properly
tightened.
B.
Before connection to the power source,
perform a visual check of all connections and wiring.
