racket ball court?

[twd22285]

There is a racket ball court that our company is going to sprinkler and i'm here to ask you oh so knowledgeable people what head choice you used in sprinklering such a facility. The room is 20' x 40' and the plan thus far is to use 2 extended coverage concealer style heads (heads centered in room at each quarter point). reason for extended coverage is to limit the amount of heads in the room, and the reason for concealers is so it does not affect the play as much as a pendent w/ a gaurd around it would, not to mention the abuse the head would still be subject to if a pendent w/ gaurd was used. Are plan w/ the concealer plate is if the plate gets hit and falls of it would protect the head and than we just need to make sure a new plate gets put on right away. If any one has an idea or better way of protecting this area please let me know, its much appreciated

I'll be out of my office tomorrow but 'Ixaon' will take over any questions you may have, thank you.

I have done several racquetball courts and this is about the only thing that I have seen any success with. The best I have seen is where the court owner posts a sign outside that says if the sprinkler is hit and the plate falls, play is to stop until the sprinkler is repaired. You should also leave a few cover plates on site so the maintenance guys can quickly replace the plates when they get hit.

Good luck!

The last time I checked (about 6 years ago), concealed heads were NOT rated for extended coverage. Only recessed heads had that feature. Of course, things may have changed since then. If not, you might need more than (2) concealed heads. Check the manufacturer's listing for coverage using concealed heads.

Sprinkler listings change very fast. You can get up to 18'x18' listing as QR and 20'x20' listing as SR. Since this is a light hazard app and you require QR, then the best you get is 18'x18'.

This would be one of the rare instances where I would ask for a formal varience from the authority having jurisdiction.

If it's simular to a YMCA you're going to have kids who view the sprinkler as a target just to see what the heck would happen. I know, I was a kid once.

sounds like good set up not much more you can do, do not think the signage is needed.

Make the system a pre-action type. Provide heat and smoke detectors to prove a fire is real before admiting water to the heads. This is done often in gymnasiums.

smokes are going to give the players more things to aim at

One more sign you might need to disply is for the maintenance grew instructing them not to use silicone sealer to hold the plate on! We did a project that was all concealed sprinklers, about 200 of them, and after we turned our backs, the painter went through and caulked the gap between the plate and the ceiling. True story.
