Free To Choose

Our professional engineering staff designs customized facility management systems tailored to meet each client’s exact specifications. Our business is headquartered out of Sioux Falls, SD; with a branch office in Fargo, ND.


Our business is based on honesty, integrity, and sound ethics, which is why we give our clients the freedom to choose. Our Tridium AX based facility management systems are designed to empower our customers and give them the freedom to choose control components that make the most sense for their facility. It also gives them control over who has access to their systems and how they access those systems.

Direct Digital Control
History, Mission And Values

We design our systems to give customers the ability to choose who will service and expand their facilities management systems. With us, customers are no longer locked in by a proprietary control system. We believe our superior customer service speaks for itself.


Our leading-edge technology makes even complex tasks simple. Internet access allows us to be on-site with just a click of a mouse to provide system operation and remote troubleshooting from anywhere. We want our customers to have the ability to choose whom they do business with; customers should not be forced into doing business with anyone just because their control system doesn’t allow it. The openness of our systems is not the only benefit. 


Our system provides authorized users access to the system anywhere online. Alarm notifications through email and cell phones ensure you a fast response and minimize your efforts in managing the facility. We provide migration paths for our customers to preserve the investment they’ve already made in their existing systems and eliminate the need to replace existing controls. We are committed to being as efficient and sustainable as possible.
