The emphasis of safety for First Responders led to control systems designed to tie Whelen products together.
 Whelen emergency vehicle control systems and technology have evolved over the years, with the largest team of design engineers in the industry, the innovators at Whelen are always prototyping new products and technologies. Whelen prides itself in innovative products guided by creativity, firsthand experience, and engineering excellence. Many Whelen engineers are fire volunteers and EMT’s with firsthand knowledge of the mission-critical aspects of Whelen products.

Whelen Cencom Core®

Released in 2019, CenCom Core® is Whelen’s most intelligent emergency vehicle control system and is engineered to enhance first responder and motorist safety with advanced automation and remote connectivity. Allowing for access to every connector and fuse from the top of the box, CenCom Core is an innovative product both inside & out.

Whelen CenCom Core comes equipped with Vehicle-to-Vehicle (V2V) Sync, which when installed by an expert has the ability to automatically synchronize lights and tones on multiple vehicles to aid approaching motorists and help ensure safety of officers and first responders.

CenCom Core includes Dynamic Variable Intensity (DVI™) patterns, which are flash patterns designed for advanced levels of safety at nighttime emergency situations. DVI patterns gradually increase and decrease warning light intensity to better indicate visual information to approaching motorists.


Whelen CenCom Core is powered by WeCanX®, a smart CAN-based communication system that synchronizes your system with greater speed, expanded peripheral add-ons and full support of diagnostics.

Connect Whelen lightbars, sirens, control heads, amplifiers and more. WeCanX technology can receive remote firmware and configuration updates using the Whelen Cloud Platform®.
