Fire sprinkler heads 101 — types, temperature ratings, and when to replace them
Record useful sprinkler-head information and recognize when changes need qualified review.
Identify equipment without disturbing it
Sprinklers have different listings and applications. Use approved records, manufacturer information and observations by qualified personnel to identify the installed equipment. Appearance alone does not establish an interchangeable replacement.
Keep changes coordinated
Ceilings, walls, storage and equipment can affect a sprinkler's surroundings. Before altering the area, give the responsible sprinkler designer the proposed plans and existing system records. Do not select spacing, temperature rating or replacement heads from a generic online table.
Document a suspected problem
Send the property address, report item if available, equipment location and clear photographs taken without touching the head. Do not paint, clean, adjust, remove or test it yourself. Escalate active leakage or an impairment promptly through the property's procedures and qualified service provider.
Use a written correction scope
The qualified team should determine compatible listed equipment, applicable design/permit requirements and verification after the work. Keep the correction record with the building's system documents. We review accepted sprinkler repair and modification scopes and confirm availability after assessment.
