Concealed Fire Sprinkler Heads
The concealed fire sprinkler head is a discreet, high-performance fire protection solution designed for residential, commercial, and industrial applications. Certified under UL 199 and compliant with NFPA 13, it delivers reliable fire suppression while seamlessly integrating into ceilings and walls for a clean, aesthetic finish.
Engineered with robust materials like brass, zinc alloy, and stainless steel, concealed fire sprinkler heads offer exceptional corrosion resistance and durability, even in harsh environments. Designed to be flush with the ceiling, they use concealed fire sprinkler head covers to blend into interiors while maintaining rapid activation. The compact, customizable design and technical adaptability make these concealed fire sprinklers a trusted choice for diverse fire safety needs.
Detail
The concealed fire sprinkler head addresses the specific needs of spaces requiring both safety and aesthetic integrity. Designed with a concealed cap and flat plate, the residential concealed sprinkler activates when the surrounding temperature exceeds a preset threshold, releasing water through a precisely engineered nozzle. The sprinkler systems ensure that the head is installed flush with the ceiling or wall to provide a smooth, clean finish.
The sprinkler’s profile covers and cover plate are available in standard decorative finishes or custom decorative finishes to meet design requirements, making them ideal for modern interiors. Each concealed fire sprinkler head supports heat-sensitive glass bulbs in 3mm and 5mm diameters, ensuring rapid activation within ≤3 seconds.
Constructed from materials like brass for durability, zinc alloy for corrosion resistance, and stainless steel for chemically harsh environments, the unit withstands pressures up to 175 psi (12 bar). With customizable options for materials, dimensions, and connection threads (R1/2 or R3/4), these concealed pendent sprinklers are adaptable to a wide range of applications.
In a modern office complex, concealed fire sprinkler heads were installed to provide safety without disrupting the interior design. With cover plates in standard decorative finishes, the sprinklers maintained the sleek aesthetic of the office. During a fire drill, the system demonstrated activation within 2.8 seconds, ensuring water discharge that protected the residential concealed areas while blending with the flush ceiling design.
The concealed fire sprinkler head offers a seamless blend of safety, functionality, and design flexibility. Whether used in residential or commercial spaces, its advanced technology and customizable features provide effective fire protection while maintaining architectural aesthetics. Certified to UL 199 and NFPA 13, this solution ensures maximum safety and peace of mind.
