What Type of Sprinkler & Model is This?

10/31/2025

Hello everyone, I’m dealing with a fire sprinkler system installed after 1984 that uses the sprinkler model shown below. I need to replace the sprinklers without changing the system’s overall characteristics.

Unfortunately, I can’t find the original datasheet for this model. I can test the activation temperature and the K-factor, but I’m unsure whether this sprinkler is of the conventional type.

Could anyone help me confirm if it’s a conventional sprinkler or provide any technical information about it?

Thank you in advance for your help!

Looks like a Globe Model D?

They're pretty old, I have one from '63 in my office relics

This post makes me curious about options outside of documentation or SIN#.

Is there a lab you could send this too and get the activation temp? I would also think a caliper could measure the orifice to get a K-factor, right?

Or send it to JCI (they bought/own tyco who bought globe, yeah?)

I have done a good number of projects involving very old sprinkler systems, and in general, but not always, I find I get good feedback from the original manufacturer, or by following the chain of who-bought-who in order to get data on old sprinklers.

The more photos that you can provide from different angles, the better. A lot of the time it comes down to little clues like a letter or a dimple cast into the frame, or the pintle extended beyond the deflector, or the colour of the paint.

Victaulic bought Globe in 2019. The Victaulic website has some of the carryover info from Globe on it, but this one might dig too deep for that.

Here's an article on the Globe/Victaulic deal:

Contact Victaulic and send them any pictures of it and they will send you the original cut sheets. I did that just last week.

They got back real quick, same day, I think.

I have some old catalogs. The oldest globe sheet I have is for the model G in which case that would be a pendent sprinkler. Does the opposite side of the base have a letter such D or G in the casting?

Yes you could send to a lab, however Greg has the answer. Vic will have the data sheet on file
And it does look like a standard response half inch orifice pendent globe automatic sprinkler.
I remember doing a job in the early 70 s where an architect wanted to color code the sprinkler bulbs to the room colors. I objected and somehow he got globe to furnish half inch 155 degree sprinklers in multiple colors and the fire marshal went along with him. It was a Del tech community college and this one was in Dover. I provided lots of signs for the rooms. Strange.
Point is globe would do about anything in those days. ( my opinion )

If you can read the marking on the deflector, you may find your answer.
SSP would be a standard spray pendent sprinkler
CUP would be conventional upright/pendent sprinkler (i.e. old style)

But as indicated above, it really looks like the Globe Model G pendent sprinkler.

I've lost track of my old Globe catalog. But the mint one on my desk, with the same deflector, says SSP-1 for pendent, and UL and FM logos on top of the deflector. And a patent number on the link. It doesn't look like a conventional-style deflector (distributes water up and down, approximately 40% / 60%).

By the way, for very old sprinklers from the early part of the last century, Gorham Dana's "Automatic Sprinkler Protection," which can be found on an on-line download. Currently there is a group on social media called "Collecting Fire Sprinkler Heads" with members who are very good at identifying recent sprinklers. (And yes, I cringe at the use of the word "Heads")

k-factors are used in hydraulic calculations if this sprinkler is date pre 1070s it is from a pipe schedule system not sure if it even has a k-factor.
