left end, remove the left end cap and gasket. Remove the
rubber plug from the hole in the cap and route the cable and
grommet through both the gasket and the end cap. Position the
grommet properly around the cable and in the end cap. Place
the rubber plug that was removed from the end cap into the
rear of the housing to seal the hole where the cable used to
enter the unit. Slide the #8-32 x 1/2 hex head screws into the
desired channel and replace the gasket and end cap. Ensure
the flat head screws are properly tightened for a good seal.
To change the cable entry to the right end or rear, remove
the end caps and the 6-32 x 1/2" screw(s) and lockwashers(s)
from the rear of the unit. Slide the circuit board assembly from
the housing and back into the opposite end of the housing.
Remove the appropriate rubber plug and route the cable and
grommet accordingly. Place the rubber plug that was removed
into the remaining hole. Install the 6-32 x 1/2" screw(s) and
lockwashers(s) into the back of the unit and secure. Slide the
#8-32 x 1/2 hex head screws into the desired channel. Install
the gaskets and end caps and tighten the flat head screws
securely.
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. In addition, two #8
keps nuts are also provided for securing the assembly to the
mounting surface.
CAUTION
Install the light head in an adequately ventilated
area. Never install near heater ducts.
CAUTION
After prolonged operation, the unit gets hot 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 3 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.

Standard Operation.
The single head unit (Model 352012) 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. The flash patterns are as
follows:
a.
Steady On
b.
120 FPM
c.
165 FPM
d.
240 FPM
e.
300 FPM
