The Janus Fire Systems® Sv, Lv, and Mv Series Clean Agent Fire Extinguishing System utilizes FM-200® as the extinguishing medium. FM-200® is a colorless, non-toxic gas perfectly suited to protect high value assets in areas that may be normally occupied, in locations where clean-up of other agents is problematic, when storage space for a fire suppression agent is restricted, or when an electrically non-conductive agent is required.
