Big venues are used to this. You ask them to have the local FD or building security staff stand a fire watch. This allows for the panel to be partially disabled. Some times this costs a fee, sometimes it doesn't.
Most venues know about the problem and have a procedure. If the venue has fog or haze machines, let them handle it, bringing your machine for "accents".
If there ever was a fire, and a shower cap was found on the detector, some one is possibly going to jail. The building's insurance may not pay or maybe revoked if that is found. If you use the showercap and it takes a lift machine/ladder to get to the detector, #1 step is to place a reminder post-it note on the inside of your windshield. Before #2 step, installing the showercap.
Pilots use checklists for a reason... No reason not to have a laserist's checklist when doing gigs.
I've always gotten panels defeated. But I do field stuff mainly for professionals...
Faint haze is less likely to trip a detector then gross amounts of Aquafog.
