My friend's theater was retrofitted with beam smoke detectors running between the top loading galleries. Unfortunately they are within inches of where a lineset passes. So the slightest sway or anything wider than the batten can set off the fire alarm.
I am wondering if there is some sort of retrofit bottom bumper that could be installed below the arbor in order to prevent the batten from traveling into the trigger area.
