Wholesale PricingThe Auxiliary Drain Sign is a 6"x2" aluminum identification marker required at auxiliary drain valve locations in wet pipe and dry pipe fire sprinkler systems. Per NFPA 13 and NFPA 25, auxiliary drain valves must be clearly identified so that inspection, testing, and maintenance personnel can quickly locate and operate them during freeze prevention draining, system impairments, and inspection procedures. This aluminum fire safety sign provides a durable, permanently readable identification solution for auxiliary drain fire protection locations throughout the protected facility.
Auxiliary drain valves are installed at low points in fire sprinkler piping where water or air can accumulate and cannot drain back to the main riser. In dry pipe systems, these low-point drains must be regularly serviced to prevent water accumulation that could freeze and block the sprinkler piping. The auxiliary drain sign identifies these critical service points so that technicians performing fire alarm inspection and testing rounds can locate every drain valve without referring to system drawings.
The aluminum construction of this fire safety sign provides superior durability compared to paper or plastic labels in the wet, humid environments found in mechanical rooms and sprinkler-protected spaces. The sign's compact 6"x2" profile fits standard pipe-mounted or wall-mounted sign holders used throughout commercial fire protection systems. It is a standard fire prevention signs item for any fire protection equipment supplier stocking complete sprinkler system identification hardware for new installations and replacements.

Placement Requirements
The auxiliary drain sign must be installed at or immediately adjacent to each auxiliary drain valve in the sprinkler system. In multi-story buildings with numerous drain locations, clear auxiliary drain fire protection signage prevents technicians from confusing drain valves with control valves or other system components. Place the sign so it is clearly visible from the normal access approach to the valve location.
NFPA 25 Inspection Requirement
During NFPA 25 annual inspection of fire sprinkler systems, inspectors verify that all auxiliary drain valves are identified and accessible. A missing or unreadable auxiliary drain sign is an inspection deficiency that must be corrected before the system inspection record can be signed off. Keeping replacement signs in your fire prevention supplies inventory ensures deficiencies can be corrected on-site during the inspection visit.
Is this sign required by code?
Yes. NFPA 13 requires identification of auxiliary drain valves, and NFPA 25 verifies this identification during inspection. The auxiliary drain fire protection sign satisfies this requirement. AHJ inspectors routinely check for proper valve identification during fire sprinkler system inspections — missing or illegible signs are cited as deficiencies in the fire alarm inspection and test records.
Can I use a printed paper label instead?
Paper labels are not suitable for the wet and humid environments where auxiliary drain valves are typically located. The aluminum sign provides permanent, weather-resistant identification that maintains readability throughout the system's service life without replacement due to moisture damage or fading. Aluminum fire safety signs are the professional standard for fire protection system valve identification.
