In a building where the maximum ceiling temperature will be 80F (26C), what would be the lowest permissible temperature classification for the sprinklers?

AOrdinary

BHigh

CIntermediate

DExtra high

Show Suggested Answer

Suggested Answer: A

For a building where the maximum ceiling temperature will be 80F (26C), the lowest permissible temperature classification for the sprinklers would be 'Ordinary.' This is based on the color-coding system for sprinklers, which provides a means to identify the temperature classifications of their operating elements. Each temperature classification corresponds to a range of maximum ceiling temperatures for which the classification is allowed to be installed. The 'Ordinary' classification is suitable for environments where the ceiling temperatures do not exceed the lower thresholds, making it appropriate for a maximum ceiling temperature of 80F (26C).

I thought it might be Intermediate, but Ordinary makes sense.

Definitely Ordinary, anything higher is overkill.

It should be Ordinary for that temp!

I feel like "Extra high" is definitely too much for 80F, but I can't recall the exact details for the others.

I practiced a similar question, and I believe "High" is for temperatures above 80F, so it can't be that one.

I'm not entirely sure, but I remember something about "Intermediate" being for temperatures around that range.

I think the answer might be "Ordinary" since 80F is on the lower end of the temperature classifications.

I've got this! The lowest permissible temperature classification would be Intermediate, since that range is just above the maximum ceiling temperature of 80F.

I'm a bit confused on this one. I know the temperature classifications are Ordinary, High, Intermediate, and Extra high, but I'm not sure how to determine which one is the lowest permissible. I'll have to think about this carefully.

Okay, let me think this through. The question is asking for the lowest permissible temperature classification, so I need to find the one that is just above 80F. I'm not sure which one that is, but I'll try to reason it out.
