A couple of years ago, I did a small children's Planetarium (approx. 25 foot diameter). The Engineering firm that designed the system, called out for single interlocked pre-action system with heads at the lower lip, and a wet system at the ceiling...
We had long discussions about changing to a double interlock or completely removing the PA system and just leaving the wet system at the ceiling. There were NO sprinklers within the dome. Hope this helps...

The company designing the projection surface has expressed concern that sprinklers will upset the imagery, especially close-ups of galaxies that the system is capable of projecting. The architect is asking me for an alternative and I haven't got a clue - as per usual.
