Good Morning, I am reaching out to the forum to see if anyone has encountered this situation previously, and if so how they handled the issue.
We are working on a theater project that has retractable numerous 5' x 5' acoustic panels, that may at any given time be located anywhere from entirely above the sprinklers (recessed into the ceiling) to 15 feet below the sprinklers. These panels, along with lighting and sound equipment are moved via cable hoists. The engineer has suggested options including: retracting the panels automatically upon water flow alarm, fusible links on one side of the panels so they would drop into a vertical position, and the installation of a deluge system utilizing sidewall sprinklers located below the lowest height of the panels. There are obvious issues with all the above: moving the panels and equipment while the theater is potentially occupied is not a desirable option and likely has unacceptable time delays, similar concerns with the fusible links, and the consequences of an accidental deluge system discharge in this building would be catastrophic. Additionally the space is too large to be covered with sidewall sprinklers along the perimeter. As I see it, the best (and maybe only) option is to reduce the panel size down to less than 4 foot square. Any similar experience or advice?
