Federal Signal Serial Interface Module

This Serial Interface Module (SIM) allows control of a FSJoin product, such as a lightbar or directional arrow, to be controlled by a non-Federal Signal controller, or any other 12 volt analogue switching device (including a simple toggle switch).

The SIM can be programmed with Federal Signal's free software.  The installer can assign specific lightbar functions to each 12 volt input wire.   This highly-flexible programming style allows the installer to achieve exactly what they need.

Multiple FSJoin devices can be connected to a single SIM.  The SIM has 2 x RJ45 ports, and if more devices need to be connected, a simple network splitter plug (not included) can be used .

The SIM comes complete with wiring harness.  Federal Signal part # Z858303641A .  Mount in dry area only.
