There is actually some sense to this. Not because of the color, but just to make sure the ordinary temp heads don’t end up in the wrong location.
It’s no fun when you get a call from the fitter as he get near the top of a high-rise apartment that goes something like this: “I need to order more ordinary temp heads. For some reason, we only have intermediate temp for the last three floors.” And you know that you ordered the right amount of each… -Kyle M From: Sprinklerforum [mailto:[email protected]] On Behalf Of Shawn Foor Sent: Friday, November 9, 2018 7:51 AM To: [email protected] Subject: Re: [EXTERNAL] RE: Sprinklers next to Diffusers I have had an architect and ahjs ask for intermediate temp head throughout so there wouldn’t be two different color bulbs On Fri, Nov 9, 2018 at 08:43 Kyle.Montgomery <[email protected]<mailto:[email protected]>> wrote: Depends on how you read that table (6.2.5.1). The way I read it, says that you can only use ordinary temp heads if your maximum ceiling temperature is 100 degrees or less. And you can only use intermediate temperature heads if your maximum ceiling temperature is 150 degrees or less. But it doesn’t say you can only use intermediate temp heads if your maximum temperature is between 100 and 150 degrees. If the maximum ceiling temperature is 85 degrees, that is still less than 150 degrees, so intermediate is OK. I think a lot of people interpreted it incorrectly to mean you could ONLY use intermediate temperature if the max ceiling temp was above 100 degrees, which is why they added the language in 8.3.2.1. Think about the fact that we can use high-temp heads in ordinary and extra hazard occupancies. Except during a fire, these areas probably aren’t seeing temperatures over 150 degrees, right? But that still doesn’t totally solve the original poster’s problem, since he has to work off of table 8.3.2.5( c ) for residential heads, although it allows him to get a little closer. -Kyle M From: Sprinklerforum [mailto:[email protected]<mailto:[email protected]>] On Behalf Of BJ Newlin Sent: Friday, November 9, 2018 6:44 AM To: [email protected]<mailto:[email protected]> Subject: [EXTERNAL] RE: Sprinklers next to Diffusers Are you allowed to use intermediate sprinklers everywhere? In 13 Section 8.3.2.1 seems to interchange the use of intermediate and ordinary, but table 6.2.5.1 indicates that if the maximum ceiling temperature does not exceed 100° Ordinary sprinklers are to be used. I know this is a gray area we take advantage of to ensure our fitters don’t have to look at what they’re installing, but is it technically in compliance with code? B.J.

Generally, my experience has been that if they have a heat pump, max outlet temperature will be less than 100 degrees. But if they have a furnace, there is a good chance it will be higher.
