Concealed Sprinkler Head

The Concealed Sprinkler Head is a recessed, cover-plate sprinkler designed for environments where maintaining a clean, uninterrupted ceiling appearance is as important as fire protection. The decorative cover plate conceals the sprinkler body within the ceiling until heat causes it to drop away at a lower temperature threshold than the sprinkler itself — ensuring timely activation without compromising aesthetics. Senju concealed sprinkler heads are widely specified for hotels, corporate offices, hospitals, and high-end commercial interiors where standard exposed sprinkler heads would detract from the interior design, while still meeting full NFPA 13 compliance and UL listing requirements.
