Guide to Viking Escutcheons

Escutcheons ensure proper timing and spray patterns for Viking sprinkler heads

With 100 years in the fire protection business, Viking manufactures and sells some of the best fire sprinklers on the market. Their pendent, upright, and sidewall fire sprinklers fill a variety of needs, including standard to extended coverage, standard to quick response, and wet, preaction, and dry systems. They have corrosion-resistant models. And Viking offers escutcheons that are specifically designed to work with their sprinkler heads.

The word “escutcheon” came to us by way of Old Norman language from the Latin word “scutum,” which means shield. In the context of fire protection, escutcheons shield and cover gaps where fire sprinklers protrude through holes cut in walls or ceilings. Their purpose is decorative, yes—they come in all sorts of attractive finishes. But escutcheons are also functional.

Fire sprinkler heads activate at a particular temperature. When the gap around a sprinkler is not covered, hot air can rise past the head into the sub-ceiling, delaying activation. Without an escutcheon, some fire sprinklers won’t work properly.

Make sure you have the right escutcheon for your Viking fire sprinkler heads. Escutcheons are not one-size-fits-all—it’s important to match the size and style of a fire sprinkler head to the escutcheon. For example, a ¾” pendent sprinkler can’t use an escutcheon meant for a ½” sprinkler head on a sloped ceiling.

There’s a lot of space behind a drop ceiling. Without an escutcheon, hot air rises through the hole cut in the ceiling panel instead of collecting around the sprinkler head. This can delay the activation of the sprinkler during a fire. Source: Fire Engineering

In this article, we make it easy to get the right Viking escutcheon by explaining the Viking part numbering system. We also provide an escutcheon buying guide that explains which sprinkler heads are compatible with each escutcheon model, including:

If you have a sprinkler identification number (SIN) for a specific Viking sprinkler model and want to search for an escutcheon that will match, press Control-F (Windows) or Command-F (Mac) while on this page. Type in the SIN and scroll up to see which escutcheon matches.

Model, size, finish, and part number—shopping for Viking escutcheons

Shopping for Viking fire sprinklers and escutcheons isn’t too difficult if you understand the part-numbering system. They have numerous escutcheon models, including 6 core models: NP-1, E-1, E-2, E-3, G-1, and F-1.

Each of these models has unique features, including:

  • Installation methods—either slip-on or threaded.
  • Fit—recessed, flush, or slanted ceiling.
  • Range of adjustability.
  • Material—all models are available in cold-rolled steel, and some are offered in stainless steel for corrosion resistance.
  • Size—models fit 1/2”, 3/4”, or 3/8” National Pipe Thread (NPT) sprinkler heads.

Ultimately, the easiest way to shop for escutcheons is by 5-digit part number. Viking escutcheons have part numbers unique to their model, material, and size. For instance, the Model E-1 has five unique part numbers, three for each size of the cold-rolled steel variety, and two for each size of the stainless steel variety.

Confused? It gets a little more complicated. Viking escutcheons also come in different color finishes, but this doesn’t change the part number. An alphabetic suffix on the escutcheon part number indicates the color. Available color finishes include:

  • White (an M/W or AM/W suffix after the part number)
  • Black (M/B)
  • Bright Brass (B)
  • Antique Brass (B/A)
  • Brushed Brass (B/B)
  • Polished Chrome (F)
  • Brushed Chrome (F/B)
  • Nickel PTFE (JN)

Viking can also manufacture custom colors as needed.

Read on, and we'll help you match various Viking escutcheon part numbers to their respective sprinklers, the latter of which are identified by their sprinkler identification number (SIN).

NP-1 escutcheons work with the XT1 line of fire sprinkler heads

Viking’s NP line of escutcheons—models NP-1, NP-2, NP-3, and NP-4—features recessed installation and adjustability. Critically, these NP-model escutcheons are the only escutcheons rated for XT1 fire sprinkler headsViking’s “next generation” of fire sprinkler heads.

Diagram of Viking NP-1 Escutcheons

Designed specifically for Viking's "next-generation" XT1 fire sprinklers, the NP-1 has slip-on installation, an adjustment range of 5/8” flush to recessed, and is available in cold-rolled steel and stainless steel.

The primary NP model, NP-1, features slip-on installation and allows for the deepest recessing (5/8”) of the NP line.

  • Outer cup depth: 1-1/16” (27 mm)
  • Outer cup outside diameter: 3-1/16” (78 mm)
  • Depth of center adapter ring: 11/32” (9 mm) +/- 1/32” (1 mm)

Model NP-1 is available in sizes fitting 1/2” and 3/4” NPT Viking sprinklers. For each size, standard cold-rolled steel and corrosion-resistant stainless-steel variants are available. XT1 fire sprinklers come standard with stainless steel deflectors; pair them with a stainless-steel escutcheon to reduce corrosion.

E-1 escutcheons for 3/8” NPT sprinklers—part number 11123

Model E-1 is the only Viking escutcheon model available for 3/8” NPT sprinklers. This cold-rolled steel escutcheon has part number 11123.

This lack of selection is because 3/8" sprinklers are rare. In fact, one of the only such heads now mentioned in Viking's literature is the 3/8" Micromatic Model M. Today, Viking's pages for Micromatic Model M sprinklers refer users to documents for the VK606, a horizontal sidewall head compatible with E-1, E-2, E-3, F-1, and G-1 escutcheons. In short: the 11123 escutcheon is, more or less, a legacy item for users with very specific (and possibly discontinued) heads.

The Viking model E-2 escutcheon

While the E-1 is effectively an all-purpose escutcheon, the E-2 escutcheon has a narrower purpose. This thread-on recessed escutcheon comes only in cold-rolled steel and fits in 1/2” and 3/4” NPT fire sprinklers. It is suitable for 49 different Viking sprinkler heads and has the following specifications:

  • Outer cup depth: 13/16” (21 mm)
  • Outer cup outside diameter: 3-1/8” (80 mm)
  • Depth of Center Adapter Ring: 21/32” (17 mm)
  • Adjustment Range: 27/32” (21 mm) total adjustment, max recess
  • Max recess: 1/2” (13 mm)

Viking’s model E-3 escutcheon is ideal for seismic purposes

NFPA 13: Standard for the Installation of Fire Sprinkler Systems has special requirements for earthquake-prone areas. One of these is that clearance should be left around pipes when they pass through walls or ceilings. When a large space is left around a fire sprinkler head, a large escutcheon typically fills the gap.

Viking’s E-3 escutcheon, a thread-on model with a large 5 1/8” outer diameter, is perfect for this purpose.

Viking’s model G-1 works on vaulted and sloped ceilings

Get the right escutcheon for your Viking fire sprinklers

When shopping for fire sprinklers, you have many choices. Viking offers a wide range of fire sprinklers and the escutcheons to match them. If you choose Viking fire sprinklers, you’ll need Viking escutcheons to fill the gaps. Escutcheons are decorative, yes. But they also ensure that a fire sprinkler head activates when it should by preventing heat from rising past it.

The NP-1 line pairs with Viking’s “next-generation" XT1 fire sprinklers. Their model E-1 escutcheons work with the largest number of sprinkler heads—over 100. The odds are that your sprinkler head is among them. The F-1 line of escutcheons is also broadly compatible, but Viking has discontinued it. If you need this model of escutcheon, QRFS can help.

E-2 escutcheons fit a niche range of fire sprinklers. Viking’s E-3 escutcheons are uniquely suited for earthquake-prone areas. Their large diameter makes them great for covering the gaps required to give fire sprinkler heads room to move in seismic events. Finally, the G-1 escutcheon lets you install fire sprinkler heads at an angle to the ceiling or wall—perfect for slanted roofs and vaulted ceilings.

When shopping for escutcheons, be careful to select the correct size, the correct material, and the correct finish. A 1/2” escutcheon won’t work for a 3/4" sprinkler head, for instance. And a brass escutcheon may clash with a white ceiling.

For all your sprinkler needs, shop the Viking commercial fire sprinklers, residential fire sprinklers, escutcheons, cover plates, and tools on our website. If you can’t find a component you need—or need it in a different size, material, or finish—contact us at (888) 361-6662 or [email protected].

We’ll help you get it!
