The problem
You’ve got a fire sprinkler system that’s decades old, and now an escutcheon (or more than one) is damaged or missing—but replacements from Gem, Central, or Star don’t exist anymore. These manufacturers are gone; you can’t find a replacement, leaving you stuck staring at exposed gaps in ceilings or walls. Even worse, it may not just be a cosmetic issue—missing or damaged listed escutcheon types are compliance problems waiting to be flagged by an inspector.
You can’t just leave the exposed hole around the sprinkler as-is, but finding a compatible replacement feels like chasing a dead end. Don’t worry; there are solutions!
Why this matters
Escutcheons are essential parts that cover the gap between sprinkler heads and the edges of the holes cut in ceilings or walls to expose them. If an escutcheon (usually its outer ring) goes missing or gets significantly damaged, the sprinkler and otherwise finished surface will not look pretty.
Worse, if you’re missing a listed escutcheon—and in the case of Star, Central, and Gem escutcheons, those will typically be recessed escutcheons—it’s an NFPA 25 violation that an inspector will flag as a deficiency:
From the 2026 edition of NFPA 25
5.2.1.1.5 Where escutcheons and coverplates for recessed, flush, and concealed sprinklers are found to be missing or show signs of any of the following deficiencies, they shall be replaced with listed escutcheons or coverplates that are part of the listed sprinkler assembly:
(1) Physical damage
(2) Corrosion detrimental to sprinkler performance
(3) Loading detrimental to sprinkler performance
(4) Paint, other than that applied by the sprinkler manufacturer, detrimental to sprinkler performance
This means you can’t just slap in any replacement—you need a listed escutcheon that’s specifically compatible with the sprinkler, or you risk failing inspection, compromising system performance, and ruining aesthetics.
The fix
Even though Gem, Central, and Star are obsolete, you still have options. Tyco, one of the leading fire protection manufacturers, now supports many of these older sprinklers with compatible Style 10, Style 20, Style 30, Style 40, and Style 50 escutcheons. This table shows what replaces what:
Buyer’s guide
Start by identifying what equipment you currently have:
- Check for a part number or other identifying marks on an existing escutcheon (if you have one and the label and any other markings are still readable).
- If that’s not an option, identify the sprinkler head via markings on the deflector or frame.
- Cross-reference this info with old manufacturer data sheets to identify the correct old escutcheon, and match it with a new, compatible model.
Once you know what your original escutcheon is, you can match it to a Tyco Style 10, Style 20, Style 30, Style 40, or Style 50 model that fits your sprinkler.
If there’s no direct replacement, your only option is to replace both the old sprinkler and escutcheon with a modern listed assembly that has the same performance specs. Whatever steps are needed, the process will involve some online investigation. You can contact QRFS, and we’ll help!

FAQs
What if I can’t find any clear product numbers or markings on my old escutcheons?
This often happens with these older parts, as labels and other markings may wear off. So, identify the sprinkler instead. Look for markings on the sprinkler’s deflector or frame, conduct an online search based on them, and consult the old manufacturer’s data sheet to determine compatibility. QRFS can help!
Can I use any escutcheon that fits the opening?
Not if it is a listed escutcheon, which will be either a recessed escutcheon or one used on special flush-style sprinklers. In those cases, a replacement must be a listed escutcheon that is part of a compatible sprinkler assembly. If you aren’t replacing a listed escutcheon, you can use any generic standard or 401 escutcheon that fits, including retrofit models. Read this blog to figure out what is and isn’t a listed escutcheon.
What happens if there’s no compatible replacement escutcheon?
If it’s a listed escutcheon, you’ll need to replace both the sprinkler and escutcheon with a modern listed combination. This requires identifying the old sprinkler and finding a new model that has the same key performance characteristics.
Does Tyco also offer new sprinklers that can replace old Gem, Star, or Central sprinklers?
Yes, many Tyco sprinklers have the specific performance characteristics to replace legacy sprinklers from those brands. This is often the most convenient option. However, other brands also have sprinklers that could fit the bill.
