Limited Energy

We provide the latest in low voltage systems design, installation, service and maintenance. We've worked with all kinds of clients - from small businesses and mutli-building high-rises to commercial, industrial and institutional.

We install and certify cable for the following systems:

Voice / Data

The foundation of our Technologies Division is the successful delivery of structured cabling systems for voice and data communication networks. Our extensive experience in this sector ensures we can provide our customers quality installation using the most respected and reliable manufactured products available. We provide solutions that include copper category cables and fiber components for customer premises and outside plant applications.
Fire Alarm

Fire alarm systems are one of the most critical systems within a building. Our technicians specialize in complex addressable and standard systems that will integrate into other systems in your building. We can upgrade your existing fire management system or install a complete stand-alone system.
Nurse Call

Nurse call systems are a special form of communication system for those with patient care responsibilities - we have installed these types of systems for some of the nation's best health care facilities including the Mayo Clinic in Rochester, MN.

Sound / Paging

Sound and paging systems complement and enhance the many other technology systems that we deliver. We install systems for paging, amplification, mass notification and sound masking.

Security, Card Access, Cameras

We offer traditional analog, digital and hybrid cabling quality installation. Our systems include networked or stand-alone digital recording and monitoring, high speed pan-tilt-zoom (PTZ) dome cameras, video motion detection, covert camera systems, retrofits of existing systems. We take pride in developing security at its most secure levels including voice/data, proxcard, CCTV, card access and AVI.


We offer design, installation and maintenance of systems for electronic display, digital signage, meeting and presentation rooms, satellite/cable/master antenna television (SMATV/CATV/MATV), broadcast and video distribution. Our manufacturing partners ensure that our customers receive the most current technology and system components available while maintaining their user-friendly quality.


We have developed the staff and skills necessary to provide complete fiber-optic solutions. We provide and install fiber for use in premise applications such as voice, data, security, fire alarm, video, process control and building automation. We can also deliver outside plant fiber-optic systems. Traditional single-mode and multi-mode systems are available.
