Control Wires for the Serial Interface Module

The serially controlled SIFM SpectraLux
Network Siren/Controller or to the Serial Interface Module. Table 2 shows the default
functions of control wires from the Serial Interface Module. The first color of wire is the
wire predominant color and additional colors are stripes. For programming options, see
the instructions included with the Interface Module or the Federal Signal Convergence
Network Siren/Controller.

Wire Color Description of Function
Blue Lowest priority
Blue/White Overrides Mode 1
Black/Red Overrides Modes 1 and 2
Turns OFF power to the Split Front ILS
Orange/Black
Turns ON power to the Rear ILS
Blue/Black Typically a high activity pattern. Overrides all three
priority modes. Scene Light, Left is unavailable.
White/Black/ Dims the lights approximately 50 percent to
Red prevent blinding approaching drivers. Low Power
is available only in Modes 1 and 2 and is disabled
when switched to another flash pattern, including
Mode 3 and Intersection.
