FM200 ROOM INTEGRITY TEST
Manycon Saudi is one of the best FM200 Room Integrity Contractors in Saudi Arabia & all GCC & India
The ability for the gaseous agent to be retained in the protected room for an extended period of time is critical to the performance of any total flooding clean agent fire extinguishing system. NFPA 2001, Standard on Clean Agent Fire Extinguishing Systems, requires that a minimum concentration of 85% of the adjusted minimum design concentration be held at the highest level of combustibles for a minimum period of 10 minutes. Those installing these systems are required to perform a Room Integrity Fan Test to assure the protected room will hold the agent for the required period of time.
A Room Integrity Fan
Test, also known as a Door Fan Test, is simply a way to measure the leakage of
an enclosure. A large fan is temporarily installed in the doorway of the room
to be tested, with the fan blowing into the room (pressurizing the room). The
fan speed is adjusted to obtain flow pressure equivalent to the pressure
exerted during a fire suppression system discharge. The fan is then reversed on
the door to draw air from the room (depressurizing the room). The airflow and
pressure readings obtained are entered into a computer program designed to
calculate the equivalent leakage area (ELA) for the room. When a room has a
suspended (drop) ceiling, then the below ceiling leakage area (BCLA) is
calculated as one-half the total ELA and is used in the calculations for
retention time. Given that most gaseous chemical agents used for fire
suppression are heavier than air, the agent will begin to leak out of any lower
level penetrations left unsealed.
