holes center to center spacing should be between 3-5". 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. 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
