[labnetwork] Smoke detectors in the clean room

[savitha.p]

Hi!

We had a fire recently inside the cleanroom and our smoke detectors did 
not give any warning even though the fire was burning for ~5min before 
it was put out. We currently have smoke detectors, a VESDA system 
installed inside the room with 3 detectors, one at the plenum level, one 
in the room and one under the raised floor (room is square shaped with 
~700 sq.ft area, Class 1000).

We were wondering how the other fabs handle these kind of situations. 
What is the ideal distance between smoke detectors and how do you ensure 
that the smoke is driven over the detectors no matter what the location 
of the fire is.

Please let us know your thoughts on this matter.

Thanks and regards,

Savitha
