Enclosure Integrity Testing

DSI has technicians on staff who are Certified to test and inspect your clean agent protected room(s) to make sure that in the event of a fire and subsequent discharge of your clean agent system, the room will hold the suppression agent long enough for trained personnel to respond. The "Door Fan Test" as it is commonly known is required on all new installations and is required annually by the City of Houston*. Other jurisdictions may not require an annual test but NFPA 2001** (Standard for Clean Agent Fire Extinguishing Systems) requires at a minimum that the enclosure be thoroughly inspected annually for any penetrations that could compromise the room's integrity and if that integrity is questionable, the Door Fan Test shall be ran to confirm.

*City of Houston Life Safety Bureau Standard on Inspection and Testing of Fire Protection and Life-Safety Equipment states in Section 2.9.6 on Total Flooding Systems (i.e. clean agent suppression systems), "Enclosure integrity for total flooding systems shall be verified annually by a licensed fire protection equipment company, using approved blower fan pressurization units, to locate and seal any significant air leaks that could cause failure to hold specific agent concentrations levels. Documentation of enclosure integrity testing and results shall be maintained."

**NFPA 2001 (2015 edition) Section 7.4 states that "enclosure protected by the clean agent shall be inspected at least every 12 months to determine if penetrations have occurred that could lead to agent leakage, if other changes have occurred that could change volume of hazard, or both. Where the inspection indicates conditions that could result in the inability of the enclosure to maintain the clean agent concentration, the conditions shall be corrected. If uncertainty still exists, the enclosure shall be retested for integrity."
