Enclosure Integrity for Clean Agent Systems

Hello All,


We are designing a FM200 system for a room that has a dropped ceiling with no protection required for the ceiling void. Further this one of the walls of the room does not extend all the way past the dropped ceiling to the roof of the building. Is the pinning of the tiles of the dropped ceiling sufficient to properly isolate the protected area from the ceiling void?


We have always used this approach but if a Door Fan Test has to be done, it may fail and using the Suspended Ceiling Leakage Neutralization Method won't work in this case.


Thanks in advance for you answers.
