Overview
The Model 331105, SMC5 is a full featured directional light control. It is designed to operate the full
selection of Federal Signal SignalMaster
®
directional lights from four to eight heads (continuous or split) at
12 V or 24 V. High current switching ability allows two full, eight-head, halogen SignalMasters to be directly
controlled by a single 331105 controller. The controller is protected against reverse polarity by a 2 A fuse and
a diode. Each SignalMaster lightbar requires an installer-supplied 20 A fuse.
This model provides six distinctive directional signals. There are standard left-arrow, center-out and right-
arrow patterns as well as special left-arrow, center-out, and right-arrow patterns that comply with CAC Title
13, Article 22 if used with the appropriate SignalMaster directional lightbar selected from the models in
Tables 1 and 2 on page 2.
