B. See figure 1. Locate the opening in the selected
mounting bolt channel and drop in two #8-32 hex head
screws.
Before drilling in ANY part of the vehicle, be sure that both
sides of the mounting surface are clear of parts that could
be damaged; such as brake lines, fuel lines, electrical wiring
or other vital parts.
C. Drill two 3/16” hole as needed for the #8-32
mounting screws. It is recommended that the screws be 2-
3” apart.
D. Secure the unit to the mounting surface using the
supplied keps nuts.
Install the control unit in an adequately ventilated area.
Never install near heater ducts.
After prolonged operation, the unit dissipates heat and
can cause burns. Do not hold the unit in your hands for
extended periods of time. Do not touch the unit during, or
shortly after, operation. Always allow the unit to cool before
handling.

III. ELECTRICAL SPECIFICATIONS AND FEATURES.
NOTE
Powering multiple devices with a common con-
trol lead may cause one or more units to briefly
remain functional after signal power is removed.
For example, due to high input filter capacitance,
a strobe supply can briefly supply the current
required to operate a low current device such as a
Cuda TriOptic. If necessary, use a relay to isolate
devices with large filter capacitors. See figure 2 for
suggested schematic, all components and wires are
user-supplied.
The unit is intended to operate on a 12.8 VDC system.
It includes a jacketed 6 conductor cable. The 6 conductors
are: red (positive), black (negative), green (programming),
yellow (external flash), orange (external flash), and white
(not used). This unit is intended to work in conjunction
with all Federal Signal switch controllers.
A.
Flashing Operation.
1. Cut and insulate the orange and yellow wires.
These are not used.
2. Connect the black wire to ground.
3. Using a user supplied 3A fuse connect the red
wire to a positive 12 VDC source.
4. This unit features 8 flash patterns that are
selected by grounding the programming wire (green). The
flash patterns are as follows:
a. Steady On
b. 120 FPM
c. 165 FPM
d. 240 FPM
e. 300 FPM
f. Combo 1:
4 intervals @ 120 FPM
10 intervals @ 300 FPM
g. Combo 2:
2 intervals @ 120 FPM
3 intervals @ 165 FPM
6 intervals @ 240 FPM
3 intervals @ 165 FPM
2 intervals @ 120 FPM
10 intervals @ 300 FPM
h. Combo 3:
1 interactive interval @ 120 FPM
2 intervals @ 120 FPM
6 intervals @ 240 FPM
14 intervals @ 480 FPM
6 intervals @ 240 FPM
2 intervals @ 120 FPM
1 interactive interval @ 120 FPM
After the desired pattern has been selected
connect the programming wire (green) directly to the
positive power wire (red).
