WHAT A CHEATER. THE FIRST GUY DIDN'T DUCK IT DOWN. YOU LIFTED IT. I'M GONNA DO THIS TO MY WIFE, BUT WITH A DIFFERENT QUESTION. TO SEE WHAT REALLY MAKE'S HER HAPPY. 👍
I carry a bag of elastic shower caps with my gear. If I have access to the smoke detectors, I ask if I can cover them for the night. Most venues LOVE the idea. I always take them down and have management double check. It's a lot easier than trying to access the fire panel and disable the alarms. Most venues don't even know how to access it! Of course, you'll need a ladder.
I can answer this. Optical type: Yes. The one over my bathroom door goes off when I take a hot steamy shower. Ionizing type: Possibly,if the particles are large and/or dense enough.
