Smoke Detector

[Rumi27]

Hello everyone,

I have a question. Can anyone help me with that? Please.

My concern is the following:
"Is it possible to implement the system so that, when the smoke detector in the room detects smoke (i.e., optical obscurity exceeding the threshold), it stops ventilation?"

If someone faced such a problem or might know if it is possible or not, can you please let me know.

Thank you very much,

I think you will need to run CFAST twice. Once to determine activcation time and then a second time where you mannually set the stop time for ventilation.
