It really depends on many factors. First and foremost is the type of
smoke detectors that are in use in your building.
Laser detectors are often the most sensitive, and anything that obstructs the optical path will trigger an alarm. There are also particulate detectors and thermal detectors and others that I don't remember all of. So are more affected by
haze than others.
Other factors also
effect how
haze will affect
smoke detectors. Air flow in the space is a huge factor. If your
HVAC system moves a lot of air and the currents keep the
haze away from detectors life could be good. however the opposite may be true. I have worked on stages where the
HVAC returns were in the
orchestra pit under the
stage which effectively sucked up most of the
haze before it could get to the ceiling and the
smoke detectors.
haze can also be effected by ambient temperature and relative humidity.
There are also different types of
haze fluids that produce different densities of
haze and different hang times. Quick dissipating fluids would be better if you are worried about triggering alarms.
The tricky thing is that sometimes you just need to test. If you can get your fire marshall in for a few hours and test different machines and different fluids, that would be best.
