Safety Message to Installers and Operators of Warning Lights

People's lives depend on your proper installation and operation of Federal Signal products. It is important
to read and follow all instructions shipped with this product and the original product. Listed below are some
other important safety instructions and precautions you should follow:
• To properly install a light assembly, you must have a good understanding of automotive electrical
procedures and systems, along with proficiency in the installation and use of safety warning equipment.
• When installing equipment or wiring inside airbag equipped vehicles, the installer MUST ensure that
the equipment or wiring is installed ONLY in areas recommended by the vehicle manufacturer. Failure
to observe this warning will reduce the effectiveness of the airbag, damage the airbag, or potentially
damage or dislodge the equipment, causing serious injury or death.
• When drilling into a vehicle structure, ensure that both sides of the surface are clear of anything that
could be damaged.
• A light system is a high current device. In order for it to function properly, a separate ground connection
must be made. If practical, it should be connected to the negative battery terminal. At a minimum, it may
be attached to a solid metal body or chassis part that will provide an effective ground path as long as the
light system is to be used.
• Locate the light system controls so the VEHICLE and CONTROLS can be operated safely under all
driving conditions.
• If a vehicle seat is temporarily removed, verify with the vehicle manufacturer if the seat needs to be
recalibrated for proper airbag deployment.
• This product contains high intensity LED devices. To prevent eye damage, DO NOT stare into the light
beam at close range.
• Frequently inspect the light system to ensure that it is operating properly and is securely attached to the
vehicle.
• File these instructions in a safe place and refer to them when maintaining and/or reinstalling the product.
Failure to follow all safety precautions and instructions may result in property damage, serious injury, or
death.

Product Overview

The Serial Interface Module is a device to communicate with Convergence Network controlled light bars.
To minimize the number of discrete wires to the light bar, control lead functions are wired to the Interface
Module. The information is converted to a digital format and communicated to the light bar via the serial
communication cable. Light bar patterns can be changed through the programming procedure.
Control leads can also activate an Internal SignalMaster
SignalMaster controller can link with the Interface Module and directly control SignalMaster operation.
The Serial Interface Module can be identified by part number 8583446 on the nameplate located on the
top of the housing. A 3-foot-long, 24-conductor, control-link cable harness is also provided for external
connection (J1) to the Interface Module.
