Room Integrity Test
door fan tests
Fire suppression systems that are built for a specific room are designed to release an agent into the room, reach a certain concentration of that agent in the air, and then hold that concentration for a set amount of time. The ability to hold this concentration is imperative in being able to quickly put out a fire. Doing a fan door test allows technicians to measure the amount of leakage from an enclosure and ensure that the correct concentration of the gaseous agent stays in the protected room to quickly put out a fire. These tests are required by NFPA 2001 for all clean agent systems.
How is a Door Fan Test Conducted?
In order to conduct a Door Fan Test, Fuller Fire & Safety Equipment Inc. will temporarily install a large ducted fan in a doorway of the protected room. This will then pressurize the room to simulate a discharge from the fire suppression system. The flow of the fan will then be reversed in order to depressurize the room, and throughout these processes, airflow and pressure readings will be recorded. Once these numbers have been recorded, the ELA, or equivalent leakage area, is calculated with specialized software to determine whether the room can hold the correct concentration for a minimum of 10 minutes. These tests are always preformed after the installation of the clean agent systems to show that every room is sealed up tight.
