An array () of multiple light heads () for a vehicle () has a primary Controller Area Network (CAN) serial data bus () to carry first serial communications among spaced-apart CAN nodes () communicatively coupled thereto. The first serial communications initiate a flash sequence from the array via second serial communications provided to the multiple light heads communicatively coupled to a nested CAN serial data bus (). An array controller () segregates the nested CAN serial data bus from the primary CAN serial data bus while providing a communications bridge between nodes of the two buses. Accordingly, light heads on the nested bus provide self-identification and diagnostic information to other nodes such as a computer () configuration utility () featuring a graphical user interface ().

Nested serial network configuration for array of serially connected light heads

A system comprising a power supply, an emergency warning light and a speaker, in combination with a control head. One or more processors controls operation of the system in response to received user input and provides system status for display. Storage media encoded with emergency warning light system instructions for execution by one or more of the processors controls the actuation of the emergency warning light system and controls light patterns generated by the emergency warning light system. The storage media is further encoded with siren system instructions for execution by one or more of the processors for controlling the actuation of the siren system and for controlling audible sounds generated by the siren system.
