Whelen CenCom Core™ is a powerful and highly versatile vehicle control system that acts as the central brain for a police car, fire truck, or any emergency vehicle's warning systems. Think of it as the ultimate smart hub that replaces a cluttered mess of switches and wires with one streamlined, intelligent unit. It works by using a central amplifier and relay module connected via a simple data cable network (called WeCanX™) to a compact, programmable control head mounted near the driver. This single controller allows an officer to manage every function—from the siren and main lightbar to grille lights, traffic advisors, and PA system—with programmable, one-touch buttons. This integration not only dramatically simplifies installation and declutters the vehicle's interior but also significantly enhances officer safety by enabling hands-free operation and complex, automated lighting and siren patterns for any situation. If you're looking to buy a state-of-the-art siren and light controller, the Whelen Core system is the premier choice for law enforcement and first responders seeking reliability, customization, and integrated control.

How It's Programmed How It's Installed Benefits for Police & First Responders Compatible Accessories and Lights 

How It's Programmed

CenCom Core is fully customized using the intuitive Whelen Command™ software. An upfitter connects a laptop to the unit to program each button for specific functions, create custom light flash patterns, select siren tones, and establish advanced "if-then" logic. For example, you can program it so that putting the vehicle in park automatically activates a right-side alley light and deactivates the rear-facing warning lights.

How It's Installed

Installation is greatly simplified compared to traditional systems. The WeCanX™ CAN-bus network allows all compatible lights and accessories to connect to the main amplifier/control module using just a few small data cables, drastically reducing the thick, heavy wiring harnesses that run through the vehicle. The control head then connects to the main module with a single cable.

Benefits for Police & First Responders

The primary benefits are enhanced safety, operational efficiency, and situational awareness. Officers can keep their hands on the wheel by using inputs like the horn ring or steering wheel buttons to cycle through siren tones or light patterns. The programmable control head provides visual feedback, showing exactly which lights are active, and its logical programming reduces the officer's cognitive load during high-stress calls.
