The INERGEN® Fire Suppression System, manufactured by Johnson Controls, is an engineered clean-agent system utilizing a fixed nozzle agent distribution network. The system is designed and installed in accordance with the National Fire Protection Association (NFPA) Standard 2001, Clean Agent Fire Extinguishing Systems. When properly designed, the INERGEN system will suppress surface burning fire in Class A, B, and C hazards by lowering the oxygen content below the level that supports combustion.

INERGEN® agent has also been tested by Factory Mutual (FM) for inerting capabilities. Those tests have shown that INERGEN agent, at design concentrations between 40% and 50%, has successfully inerted mixtures of propane/air, and methane/air. The system can be actuated by detection and control equipment for automatic system operation along with providing local and remote manual operation as needed. Accessories are used to provide alarms, ventilation control, door closures, or other auxil iary shutdown or functions.

When INERGEN® agent is discharged into a room, it introduces the proper mixture of gases that will allow a person to breathe in a reduced oxygen atmosphere. A system installation and maintenance manual is available containing information on system components and procedures concerning design, operation, inspection, maintenance, and recharge. The system is installed and serviced by Authorized ANSUL Distributors that are trained by the manufacturer.
