System Design Is Key

The key success factor for any fire protection system is its design. Fire protection depends on the early identification of a developing fire, and on alerting the occupants and emergency services. Knight Security designs and installs systems that can also initiate automatic suppression systems and interface with elevators, air handling, electrical and other special process operations. Our system designs are tailored to the type of business, building size, occupant level, the types of fires that could develop, and the protection needs of our clients.

Knight Security specialists are fully certified and knowledgeable in national, state and local fire safety codes, AHJ (authority having jurisdiction) rules, manufacturers' specifications and installation requirements.
