Standard Response vs Quick Response: Visual Difference?

[cb1151]

Is there a way to tell the difference between standard response sprinklers and quick response sprinklers by looking at the them?

My guess is by looking at the fusible link. From what I notice, standard response seems to have a thicker glass bulb. However, I'm only looking at 2 sprinklers so that could be just the manufacturers design and might not have anything to do with response.

should be markings on the deflector

Ask one of the name brand companies and they can get you a guide for the markings

SR sprinklers have a 5mm glass bulb.

QR sprinklers have a 3mm glass bulb.

That is standard across all manufacturers in the US. Otherwise, you can look on the sprinkler for SIN - sprinkler identification number and find it in the manufacturer's data sheet.

That's what I figured. Thanks to the both of you.
Travis, where can I find that in some literature or maybe NFPA?

any of the sprinkler manufacturer's web sites will have the data. Try
