Removing a fire sprinkler escutcheon, often referred to as a collar or trim ring, is typically done by carefully detaching it from around the sprinkler head.
The process depends on the type of escutcheon installed. Generally, if the current escutcheon includes an outer ring or skirt, remove them by slowly pulling them down over the sprinkler head. For other types, cutting may be necessary.
Here's a breakdown of how to remove common types of fire sprinkler escutcheons based on typical designs and practices:
Understanding Fire Sprinkler Escutcheons
Escutcheons are decorative plates or rings that fit around the sprinkler head where it meets the ceiling or wall. They serve aesthetic purposes by covering the hole around the pipe, but some also play a functional role, particularly with recessed or concealed sprinklers. They are not part of the sprinkler's fire suppression mechanism itself, but are considered trim.
Methods for Removing Escutcheons
The exact method you use will depend on the specific design of the escutcheon. Here are the standard approaches:
1. Escutcheons with Outer Rings or Skirts
According to the provided information, if your escutcheon has an outer ring or skirt:
- Slowly pull them down over the sprinkler head. This suggests a friction fit or a design that allows for simple removal by pulling.
2. Adjustable or Recessed Escutcheons
These types often consist of two parts (a cup and an inner ring) or are designed to fit snugly within a ceiling recess.
- Cut the cup (adjustable) or inner ring (recessed) using tools like kitchen shears or pruners.
- Remove the cut piece from the sprinkler head.
- Be careful not to damage the sprinkler head itself during this process.
3. Flat Escutcheons (Single Plate)
Simple, flat escutcheon plates are common, especially with pendant or upright sprinklers in exposed pipe systems.
- For flat escutcheons, simply cut the plate and remove it. This usually involves cutting through a thin metal or plastic ring.
Step-by-Step Removal Guide
Here is a general guide, combining the methods:
- Identify the Escutcheon Type: Determine if it has an outer ring/skirt, is a recessed/adjustable cup design, or a simple flat plate.
- For Outer Ring/Skirt Types: Gently pull the ring(s) straight down away from the ceiling and over the sprinkler head.
- For Recessed/Adjustable or Flat Types: Using appropriate cutting tools (kitchen shears, snips, or pruners as mentioned), carefully cut through the escutcheon material. Make sure to cut away from the sprinkler head to avoid damage.
- Remove the Cut Pieces: Once cut, the escutcheon should come away from the sprinkler pipe.
- Inspect: Check the sprinkler head and surrounding ceiling area for any damage.
| Escutcheon Type | Removal Method | Tools (If applicable) |
|---|---|---|
| Outer Ring or Skirt | Pull down over sprinkler head | None |
| Adjustable Cup or Recessed Ring | Cut the cup or inner ring and remove | Kitchen shears, Pruners, Snips |
| Flat Plate | Cut the plate and remove | Kitchen shears, Pruners, Snips |
Why Remove an Escutcheon?
People might remove a sprinkler escutcheon for reasons such as:
- Painting the ceiling or wall.
- Replacing a damaged escutcheon.
- Upgrading to a different style of escutcheon (ensure compatibility and proper listing).
Important Safety Note: Never attempt to remove the sprinkler head itself or tamper with the sprinkler system piping. This should only be done by qualified fire protection professionals. Removing or damaging a sprinkler head can cause the system to activate, leading to significant water damage, or render the system inoperable in case of a fire.
Always replace a removed or damaged escutcheon with a new one that is specifically listed for use with your sprinkler head model and the ceiling type/assembly. The correct escutcheon is crucial for the proper operation and listing of certain sprinkler types, especially recessed and concealed heads.
