Model 331105 SMC5 SignalMaster Controller
Failure to follow these safety precautions may result in property damage, serious injury, or death.
Operating the SignalMaster Controller
See Figure 5 on page 10. All controls for the SignalMaster directional lights are located on the front panel of
the controller. The LED display simulates the active light pattern.
Function Activation
The Model 331105 controller gives the function of the latest input priority. If a warning pattern is
activated via the WARN button, and then the slide switch is activated, the controller switches from the
warn pattern to the directional pattern to which the slide switch is set. When the slide switch is then set
to the OFF position, the warning pattern resumes.
Slide Switch
The slide switch is a four-position switch with OFF and settings for the directional patterns LEFT
ARROW, CENTER OUT, and RIGHT ARROW.
■
OFF (Position 1)
Turns off the directional pattern.
■
LEFT ARROW (Position 2)
Displays a left-arrow flash pattern that instructs traffic to move left.
■
CENTER OUT (Position 3)
Displays a center-out flash pattern that instructs traffic to move to move around either side of the
vehicle.
■
RIGHT ARROW (Position 4)
Displays a right-arrow flash pattern that instructs traffic to move right.
WARN Button
Displays a non-directional warning pattern. See Table 5 on page 10 and Table 7 on page 11 for available
patterns. The slide switch overrides the pattern.
AUX Button
Operates the external lamps (if installed) independently if one of the five patterns other than Pattern 6
(all on) is selected (Table 6 on page 11.) Auxiliary heads will NOT flash if left in Pattern 6 or in the
Null pattern.
FAST Button
Increases the flash rate of the selected directional or WARN pattern. The rate of the AUX Button
function is unaffected.
