I work for a 23k seat basketball arena that made there own kabuki system, very similar to Rose Brand's system. Every home game for the last three years, we have dropped four 40' x 60' sheets around our scoreboard (portrait style) and projected video on them with the lights out to introduce the players.
One of the flaws in our system is the potential that the sheets will unveil correctly but an electrical failure would prevent them from dropping to the ground. If that happened before a game, the team would get penalized for a delay of game as I would rush to either rappel out and hit a manual release or spend the time to lower the entire truss to get them all off. We've had failures like that during rehearsals but (thankfully) never before a game.
I think it's time to get a professional kabuki system. However, I've noticed that as a matter of safety, all the systems I researched refuse to drop if they suffered a power failure. I'd like the exact opposite. I would like a system that requires power to hold the sheets and would drop them if it lost.
My thoughts are that I would put the system on relay modules of our dimmer racks and tell the configuration of the rack to treat those channels inversely (0 means power, full means off.) Then, if we had a failure, it would just be a matter of unplugging it from the rafters or pulling out the rack.
Does such a system exist?
