Hi I am looking for a good example of an aspirating smoke detector. Smoke detector rep is unclear what is need for lbs/cu ft and lbs/sec

Hi Kevin,
Thanks for the example - you don't know of a white paper or something that explains the detectors?

Xtralis literature? I've never worked with them myself. Jason Floyd knows more.

Honeywell (absorbed Xtralis and now produce VESDA) have a lot of literature on their site:
If you're looking for a general description of how ASD works, YouTube has some good videos to kick you off. https://www.youtube.com/watch?time_continue=123&v=mzrGrl-qNUw or https://www.youtube.com/watch?v=MByARnIWsFo

Hi What I was looking for was a white paper or something that describes the aspiration detectors in FDS. I am familiar with FDS spot type detectors but not the inputs needed for aspiration. What is the mass flow rate of an insipient fire ?

See the FDS User's Guide for a discussion of the inputs for an aspiration system.

I know this is an older thread, but my question is related.
Where does the Flow Rate value come from and is it dynamic in any way if the density of the gases at the sampling location change density?
Do you base the mass flow rate on the density of air?
