A.
Slide Switch.
1.
LEFT (Position 1).
In this position, the light produces a left arrow
flashing pattern, instructing traffic to move left.
2.
CENTER OUT (Position 2).
In this position, a center out flashing pattern is
produced, instructing traffic to move around either side of the
vehicle.
3.
RIGHT (Position 3).
In this position, the light produces a right arrow
flashing pattern, instructing traffic to move right.
B.
WARN switch.
When this switch is pressed, an alternating pattern is
produced. The four middle lights activate alternately with the two
outside lights on each side. The slide switch will override this
pattern.
C.
AUX switch.
1.
When this switch is pressed, external lamps
alternately flash at a constant rate. The wiring configuration
determines the flash combination of the external lamps. The slide
switch will override the external lamp pattern when the AUX
switch is depressed, but will not override the AUX OUT terminal
output.
2.
If connected, the six-position connector’s AUX OUT
connection provides a ground to activate a user-supplied relay to
control an external device.
D.
Auxiliary Input.
If connected, application of a positive (+) 12-volts to the
AUX IN connection on the six-position connector produces the
WARN pattern described above. When the positive (+) 12-volts is
removed from the AUX IN connection, the WARN pattern will
stop. Slide switch activation will override the WARN pattern.
V.
SERVICE.

performed by a qualified Federal Signal service center. If the
control unit is not working properly, disconnect all electrical
