c. To protect the wires, use an in-
line fuseholder and 2-ampere fuse (not supplied). The
fuseholder and fuse should be installed in the red (+)
lead as close as practical to the power source.
d. Route the black (-) power cable
lead through the previously drilled hole into the
engine compartment, and through existing clamps
and holders toward the battery. DO NOT make any
connections to the battery until all other wiring is
complete.
2. Optional Foot Switch.
The optional foot switch function is
activated by momentarily grounding the foot switch
input using a user-supplied foot switch (Federal
Model SWF) or other equivalent momentary contact
SPST switch.
a. Install the foot switch in a loca-
tion which allows the vehicle, controls, and micro-
phone to be operated safely at all times. In addition,
the foot switch should be installed in a location which
allows minimum reaction time in an emergency
situation.
b. Connect one side of the switch to
a RELIABLE chassis ground using #18AWG or
larger wire.
c. See figure 3-8. Connect the other
side of the switch to the power cable’s white wire
using #18AWG or larger wire.
3. Optional SS2000 Interface.
The optional SS2000 interface function
will activate the Federal Model SS2000 SmartSiren®
pursuit function using the Vision control head or
optional foot switch described above.
a. Using #18AWG or larger wire,
connect the power cable’s gray wire to the gray wire
in the SS2000’s power cable.
b. C12V to LUG1 as de-
scribed in paragraph 3-7.C. below.
C. Auxiliary Connections.
NOTE
Steps 3-7.C.1. through 3-7.C.6. below are nec-
essary ONLY if auxiliary devices are to be
controlled by the warning system.
The Vision is configured at the factory to
satisfy most installation requirements. Before
proceeding with installation, refer to the supplied
Operation and Configuration Instructions manual for
a description of the “standard” keyboard configura-
tions and for instructions on how to change the
configuration (if necessary).
The Vision provides one terminal strip
(TB1) for control of auxiliary lights and accessories. A
total of three fused relay-controlled outputs are
available.
Each output switches a n12-volts
to the controlled device. Do NOT use the black wire
in the Interface/Relay Unit power cable for grounding
the switched device(s). Ground the switched devices
separately.
Refer to the installation instructions
provided with the auxiliary devices for additional
precautions and details.
Fuse current ratings and possible uses for
each output are shown in table 3-2.
Complete the wiring to the accessories as
follows:
1. Remove the chassis cover by loosening
the 2 screws on the bottom of the Interface/Relay
Unit. See figure 3-7. Slide the cover to expose the
terminal strip.
2. Route a #10AWG red wire through the
hole lBAT and attach it to the large lug-type
