If you have a fire sprinkler cover plate to replace and youre wondering which one you need, youve landed on the right page. Whether your existing sprinkler cover is missing, damaged, or painted over, in this blog youll learn the simple steps required to find the correct cover plate (hint: the manufacturer is key, little to do with dimensions) and replace it with ease.

Lets start with a quick overview. A cover plate is a decorative piece of metal connected to a copper frame by temperature-responsive solder that covers a concealed sprinkler in a ceiling. A cover plate simply screws into the concealed fire sprinkler to provide aesthetic benefits, protect the sprinkler from dirt, dust, and debris, similar to escutcheons (learn thedifference between an escutcheon and a cover plate). The temperature-responsive solder reacts to a specified temperature, usually 20 degrees lower than the sprinklers activation temperature. After the solder melts, the decorative plate falls to the floor exposing the sprinkler.

Occasionally, however, sprinkler covers fall off or get damaged. Cleaning, painting, and moving are all reasons weve heard. So now you have this

Before you replace, remember the fire sprinkler cover plate replacement golden rule:

each concealed fire sprinkler has ONLY ONE replacement cover plate that fits

installing the wrong cover plate can be damaging and costly. It can void the sprinklers warranty, so future repairs will be significantly more expensive. In rare cases, the wrong cover can damage the sprinkler itself, unleashing a torrent of water into the building. By all means, lets avoid that!

. If a cover plate has fallen off, dont glue or caulk it back onto the sprinkler. Caulk or glue does not react to temperature the same as the cover plates solder, resulting in a blocked fire sprinkler increasing fire risk. If your reason for replacement is the covers color no longer matches the ceiling,dont paint them.

Alright, now that weve got what not to do – how do you know which cover you need? To find your cinderella sprinkler cover, you need either: a) an old sprinkler cover or b) a ladder, so you can look at the sprinkler itself. Each manufacturers cover plate has a slightly different circumference and depth, but almost all are threaded and screw into the concealed sprinklers base. If youre replacing cover plates that are attached now or if you need to replace just one of many, try unscrewing the sprinkler cover (lefty-loosie). If they spin freely but are not backing out, then they are push on so try a gentle but firm pull to remove. If neither method removes the cover, sell the building (just kidding:call us).

With the cover removed, you can now search for the Sprinkler Identification Number (SIN), or model number. A SIN is usually 5-6 digits long and preceded by one or two letters. For example, a popular concealed Tyco model is TY3551. Heres a handy list to help you translate letters to manufacturer name:

The applicable SINs are usually marked on the cover. Newer sprinkler covers often have a sticker affixed to the inside of the cover. The sticker specifies the manufacturer, temperature, and a list of SINs the cover matches. Newer model Victaulic, Tyco, and Viking cover plates all feature a sticker. If there is no a sticker, look for a stamp which is preferred by Reliable and Senju today and many manufacturers in the past. See the image below for examples of both.

If all your cover plates are gone, dont panic! The SIN and other information are commonly stamped on the sprinklers deflector. See the image below. The SS8461 shown is the number you need. It is important to note, cover plates are often compatible with a variety of sprinklers offered by the same manufacturer. Once you have the SIN, the next step is ordering the right replacement.

Identify the correct cover plate by first finding your brand and then finding the Sprinkler Identification Number (SIN) associated with your fire sprinkler in the table below. Click the link below the image to purchase in your preferred finish!

Admittedly, we do not have access to every cover plate made. Additionally, the manufacturers, for their part, do not support every concealed sprinkler theyve ever produced. That latter point is the most common reason people are unable to replace their sprinkler covers. If your sprinkler is a model that is no longer manufactured, locating a cover plate will not be easy. Your best bet is to call the manufacturer to ask if their other distributors might have some old stock on the shelf (weve provided a list below). Unfortunately, if you cannot find the right replacement cover then replacing the sprinklers is the only alternative.

Installing a new cover plate is as simple as twisting or pushing it on. Only install once you are certain you have the cover plate that is meant for sprinkler but you knew that already, right?

Once the cover plate is installed, there should be a small gap between the ceiling and the lip of the cover plate. This is to allow heat to flow from a fire to the three solder spots, ensuring the cover releases on time during an emergency.
