All installation and upgrades must be performed with a licensed commercial fire alarm contractor in your local area. The NFPA 72 is the fire alarm code that governs the installation of industrial and commercial fire alarm systems. It states "Fire alarm system plans, specifications and installation shall be developed in accordance with this code by a person who is experienced in the proper design, installation and testing of fire alarm systems."
Federal, state and local fire alarm codes determine how a commercial fire alarm system must be installed, maintained, inspected and tested in commercial buildings. Even though the fire alarm designer is responsible for the design and operation of a fire alarm system, the fire alarm contractor is the responsible for the installation, operation and programming. Your fire alarm company will have experience and knowledge to install a fire alarm system in accordance with the designed plans and applicable fire alarm codes and regulations.
