circuit board assembly out of the housing. Slide the assembly
into the opposite side of the unit. Install the #8-32 screws/lock
washers to lock the assembly into the housing. Remove the end
cap and gasket from end of the grommet/cabling assembly.
Remove the right rear plug from the housing and install it into
the end cap where the grommet/cabling assembly was in-
stalled. Route the cabling towards the right rear of the unit
and install the grommet into the slot where the plug was
installed. Before replacing the end cap/gaskets, slide in the two
#8-32 x 1/2" hex head machine screws into the desired mount-
ing channel. Install the left plug in the rear of the housing.
Replace the gaskets and end caps using the four flat head
screws. Insure the end cap screws are properly tightened for a
tight seal at both ends.
CAUTION
Before drilling holes in ANY part of 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.
A 3/16" diameter mounting hole is recommended for the
two #8 x 1/2" mounting hardware screws. The recommended
holes center to center spacing should be between 2-3". In
addition, two #8 keps nuts are also provided for securing the
assembly to the mounting surface.
CAUTION
Install the control unit in an adequately ventilated
area. Never install near heater ducts.
CAUTION
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.

ELECTRICAL SPECIFICATIONS AND FEATURES.
NOTE
Powering multiple devices with a common control lead
may cause one or more units to briefly remain
functional after signal power is removed. For example,
due to the 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 5 for the
schematic; all components/wires are user-supplied.
The unit is intended to operate on a 12.8 VDC system. It
includes a 3 conductor connecting cable housed in a black
jacket. The 3 conductors are: red (positive), black (negative)
and green (switching). This unit is intended to work in
conjunction with all Federal Signal switch controllers.
1.
Standard Operation.
This unit features 8 flash patterns that are selected by
applying the switching wire (green) to the ground wire (black).
These wires are all within the black cable attached to the unit.
Install a 3-ampere fuse in the red wire. Connect the red wire to
a switched 12V source to activate the light. The flash patterns
are as follows:
1.
Steady On
2.
120 FPM
3.
165 FPM
4.
240 FPM
5.
300 FPM
6.
Combo 1:
4 intervals @ 120 FPM
10 intervals @ 300 FPM
7.
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
8.
Combo 3:
1 inactive interval @ 120 FPM
2 intervals @ 120 FPM
6 intervals @ 240 FPM
14 intervals @ 480 FPM
6 intervals @ 240 FPM
2 intervals @ 120 FPM
1 inactive interval @ 120 FPM
After the desired pattern has been selected, the green
wire must be connected directly to the red power lead.
This unit is designed to return to the last flash
pattern selected before it was de-energized. For example, if the
unit is de-energized at the seventh flash pattern and then re-
energized, the seventh flash pattern illuminates. However,
there is a two-second delay for the unit to remember the last
pattern. So, if the unit is energized and functioning on the
-3-
