Signs in a fire sprinkler system are crucial for enhancing safety, communication, and effective operation. They help individuals quickly locate fire sprinkler system components, including control valves, water supply connections, alarm devices, and sprinkler heads. This ensures that these critical components can be easily found and accessed during maintenance, inspection, or emergency situations.
In the event of a fire, firefighters need to quickly understand the layout and operation of the fire sprinkler system. Clear signs indicate key information such as the location of control valves and the type of sprinkler system in use, enabling responders to take appropriate actions swiftly.
Signs can provide safety instructions related to the fire sprinkler system. For example, signs might indicate the importance of not obstructing sprinkler heads, valves, or fire department connections, ensuring that these vital components remain accessible and functional.
Clearly visible signs discourage tampering or unauthorized adjustments to the fire sprinkler system. When the system's components are clearly marked, it's easier to detect and prevent interference.
Signs can provide important information about the fire sprinkler system, such as the type of system (wet, dry, pre-action, etc.), water supply sources, and water pressure details. This information is valuable for maintenance personnel, inspectors, and firefighters.

Fire codes and regulations often require signs to be placed at various points within a fire sprinkler system. Compliance with these requirements ensures that the system is properly identified, maintained, and accessible.
NFPA 25 and Signage Requirements
NFPA 25, Standard for the Inspection Testing and Maintenance of Water-Based Fire Protection Systems, provides the minimum requirements for properly maintaining water-based fire sprinkler systems. Within this standard are several requirements for maintaining proper signage.
Many in the industry are unaware of the requirements for proper signage. Of course, the requirements do change from edition to edition. Let us start with what is not required. Many technicians cite the building owner for not having signs such as main drain, inspector’s test connection, and alarm line signage.
Section 13.3.1.1 requires additional signs when more than one control valve must be closed to work on a system. It requires a sign on each valve referring to the existence of the other valves. For example, a looped system in a high-rise. The sign does not appear to have a specific inspection frequency however, control valves are required to be inspected either weekly, monthly, or quarterly depending on how they are supervised. This section requires the sign to be inspected annually for legibility and that it is securely attached.
This section requires a sign to be placed at the control riser that supplies an auxiliary system to include antifreeze, dry, or preaction systems. This sign has been required by NFPA 13 since the 2007 edition but was not required by NFPA 25 until the 2014 edition. This sign has many requirements and may cause some discussion between the building owner and service provider. Annex note A.5.2.8 states that this sign should satisfy the requirements for the information sign noted in Sections 5.2.7 and 4.1.9.

All the signs discussed are required by NFPA 25 and should be cited as a deficiency if not present where required. The signs that are required by NFPA 13, such as the main drain sign, are good ideas to have but are not required by NFPA 25. If a technician wants to suggest having these signs, it should be done on an observation report.
The NFSA’s expert of the day program is an excellent resource for answering all your fire protection questions. Our staff sit on several NFPA technical committees and work very closely with a number of standards. With expert of the day, NFSA members ask questions relating to anything surrounding fire protection, from winterization, to fire sprinkler monitoring, and everything in between.
Types of Fire Sprinkler Room Signs
There are various types of fire sprinkler room signs available, each serving a specific purpose.
- Fire Sprinkler Riser Room Signs: Indicate the location of the fire sprinkler riser room.
- Sprinkler Control Room Signs: Help locate and identify the control room for the fire sprinkler system.
- Valve Identification Signs: Identify crucial components of a Fire Sprinkler System and the system’s operation.
Materials and Mounting
Sprinkler system plates comply with the requirements of NFPA 13. They identify crucial components of a Fire Sprinkler System and the system’s operation. Identification sign location varies by type, but in general these should be applied on valves controlling and supplying a sprinkler system.
When selecting a sign, consider the following options:

- Substrate Choices:
- Enamel-coated 1mm aluminum
- Semi-rigid 1mm PVC plastic
- Flexible vinyl label stock with permanent adhesive
- Heavy duty, flexible magnetic backing that clings to ferrous metals (not stainless steel)
- Mounting Options:
- Aluminum and plastic signs have holes in each corner for easy mounting.
- Labels have self-adhesive backing - just peel and stick.
All signs are printed with UV-stable ink and are suitable for indoor or outdoor use at service temperatures from -40 to +180 F.
Example of a Sprinkler Control Room Sign
A 6 in. x 2 in. Aluminum sign may feature 1 in. lettering that reads “Sprinkler Control Room”. With its highly visible white background and red finished lettering, this sign helps locate, identify, or provide instruction in Fire Sprinkler System applications. It has 4 pre-drilled holes for ease of installation and helps building owners ensure components of the fire sprinkler system can easily and quickly be located during an emergency or for maintenance.
It is recommended to consult with your local authority having jurisdiction (AHJ) to ensure the FDC and/or signage requirements in your area.
Use a Sprinkler Room Sign by PipeMarker.com to help emergency responders identify the Sprinkler Room housing your fire sprinkler system and the system’s operation. This sprinkler system sign is manufactured from rust-free aluminum - making it the perfect choice for valves controlling and supplying your sprinkler system.
