An Overview of the Discrete-Wired 24-inch Legend Light Bar

The Discrete-Wired 24-inch Legend is a special model that is designed to flash
only one flash pattern as long as power is supplied to the light bar. Because the
light bar does not connect to the Serial Interface Module, it has no CAT5 cable; the
10 AWG red and black cables are the only connections. An installer supplied-switch
is required. See schematic A 1.
