Since 1976, Primary Systems concentrates on improving the performance of your building systems, so you can concentrate on managing your business, not your Fire Alarm System. As a locally owned and operated business we understand the local codes and regulations that Fire Alarm requires. We are committed to exceeding our customer’s expectations.  

We are proud to provide you with a single source for your Fire Alarm service needs. We combine superior product knowledge, local expertise and unparalleled responsiveness to keep your building systems running at peak efficiency.  By implementing a Fire Alarm service plan, you'll improve reliability, avoid costly repairs, and prolong your Fire Alarm systems life.  Ultimately, you will minimize business disruptions and reduce building operational costs.

The most current techniques and equipment are utilized on every inspection to meet the rigorous requirements of today’s complex Fire Alarm systems. We make a special effort to thoroughly test and inspect all of your Fire Alarm systems components for proper operation.  We can significantly reduce unwanted false alarms by keeping your smoke detectors clean and ready to respond to the required sensitivity level. Upon completion of our Fire Alarm inspection we will provide you with detailed documentation as outlined by the National Fire Protection Association and your local authority.
