I've always been under the impression that these are treated separately from the overhead sprinkler system, i.e. either the fire is in the hood and controlled by the hood system, or it is outside of the hood and controlled by the sprinkler system. I've never considered them as working in

Travis, In a roundabout way, that sort of answers your question. If they aren’t allowed to connect to domestic fixtures that may be operating at the same time, then it stands to reason that they shouldn’t connect to sprinkler systems that are operating at the same time. Ergo, if they are

I think this is one of those things, just like with Hi-Ex foam generators, where you really want to get some input from the manufacturer. From: Sprinklerforum [mailto:sprinklerforum-boun...@lists.firesprinkler.org] On Behalf Of Prahl, Craig/GVL Sent: Thursday, August 8, 2019 8:51 AM To:

2019-08-08 Thread Kyle.Montgomery via Sprinklerforum
If the load calculations told you that you needed 3 longitudinal braces per branch line, I'm thinking Bob is right. There's no way you're going to be able to replace them with 1 lateral brace on the main at each branch line, unless you've got some structural member adjacent to the main that is

RE: [EXTERNAL] ESFR's and unit heaters

I'm looking at the code again, and you may be right. But I always thought that an obstruction that close to the sprinkler (could you quantify "just below the ESFR deflectors") would have to meet the rules for "Obstruction at or Near Ceiling", 8.12.5.1. Are we saying that 8.12.5.1 only applies

Also, how are you complying with the temperature rating when you are that close to a unit heater? Are they making any high temperature ESFRs yet? From: Sprinklerforum [mailto:sprinklerforum-boun...@lists.firesprinkler.org] On Behalf Of Kyle.Montgomery via Sprinklerforum Sent: Tuesday, August 20

you to 8.12.5.2 or 8.12.5.3. I'll admit, I don't work with ESFR's every day, but having read those sections multiple times, that's all I come up with.

RE: [EXTERNAL] Ex cov under OH Door

2019-09-03 Thread Kyle.Montgomery via Sprinklerforum
In the original post, I believe the area was classified as ordinary hazard, not necessarily storage. So does that change things? I agree with the previous posts that it seems odd to say we can call the area under the door light hazard when using a standard spray head but can’t do so when using

RE: ESFR Sprinklers Spacing and Height Criteria

2019-08-21 Thread Kyle.Montgomery via Sprinklerforum
Jerry, I've seen situation where they added thicker insulation at the ridgeline to account for a few inches of height. If it's a relatively small area that's over 30 feet, that might be a cost-effective solution. I believe that you can use the design criteria (head pressure) for the roof
