CenCom Core Brochure

All-New Design

Every aspect of CenCom Core is engineered for performance and designed for vast configuration, allowing for access to every connector and fuse from the top of the box. CenCom Core is built to scale with your needs.


WeCanX is the smartest and most powerful CAN-based communication system we’ve ever engineered. Providing true system synchronization, greater speed capabilities, expanded peripheral add-ons, and full support of diagnostics, WeCanX is designed for optimal situational awareness programming.

Whelen Command

At the heart of CenCom Core is Whelen’s newest software, Whelen Command. Featuring an advanced user interface, Command is engineered to streamline the entire programming process and quickly provide updates and new releases. Command can process over 65,000 virtual inputs.

Command features Situation-Based Integration and Events. With Situation-Based Integration, scene-specific functions can be created and automated, utilizing various vehicle components and signals. With Events, multiple user-defined rules can be created for specific situations and can be dependent on the state of your vehicle.

Hardware Support

Core supports up to 99 WeCanX devices -the most ever in a Whelen control system. Connect lightbars, sirens, control heads, amplifiers, input and output expansion modules, Howler amplifiers, and Inner Edge® products. With Core, you can support multiple Whelen peripherals of the same type on the same vehicle.

17 Total Inputs

  • 12 logic inputs
  • 1 ignition power-up input
  • 4 analog inputs

23 Total Outputs

  • 2 15A outputs
  • 4 10A outputs
  • 16 2A outputs
  • 1 dry contact relay
  • Flashing outputs

Firmware Updates

CenCom Core supports remote firmware updates through USB-C with Whelen Command or over-the-air with The Whelen Cloud Platform. All WeCanX devices support encrypted firmware updates.

High-Speed Connections

Core has extremely high-performance I/O. It features one ethernet connection, one WeCanX connection, two CANport OBDII interfaces, one USB-A port, one USB-C port, and one micro SD card. With a variety of interfaces, Core is ready for a variety of configurations.

WeCanX Control Heads

Ergonomically designed for situational awareness, WeCanX control heads are completely configurable. Models support flashing indicator LEDs and can also run system diagnostics. The new passthrough WeCanX connection on the back of the control heads contributes to less wiring and an easier install.

Dynamic Variable Intensity Patterns (Patent-Pending)

CenCom Core introduces Dynamic Variable Intensity (DVI) patterns, an innovative series of flash patterns designed to help create an advanced level of safety at nighttime emergency scenes.

Building on Whelen’s situation-based nighttime mode, DVI patterns produce safer environments for first responders by gradually increasing and decreasing warning light intensity.

DVI patterns help better convey visual information to approaching motorists, clearly indicating when an emergency vehicle is parked and improving their ability to navigate around an emergency scene safely.

WeCanX Devices

Now you can customize CenCom Core in ways never before possible in a control system.
