STEADY-LOCK™ Enabled Lightheads
MA:0039 • 3/30/2023
STEADY-LOCK™ is a time-saving new feature that allows Whelen’s most popular warning lightheads to be set to Steady automatically, when used with a CenCom Core® system. Installers no longer need to toggle through Scan-Lock™ flash patterns, saving them time and improving efficiency for vehicle upfitters. STEADY-LOCK is now enabled in the following lightheads: M Series™
DUO™, ION™ Series, ION V-Series™, ION T-Series™, Strip-Light™ Plus and Mirror-Beam™.
Every lighthead that is STEADY-LOCK enabled will have a lock symbol ( 
) on the model or part number label. A list of specific model numbers that now have this labor-saving feature are listed in the chart below. Detailed instructions about STEADY-LOCK are embedded in the help files of the Command Software, with a Quick Start Guide and list of frequently asked questions included at the end of this market advisory.
