Product Formation

This sprinkler head features a concealed installation design—its main body (including the valve, pipe connection, and sprinkler mechanism) is recessed into ceiling cavities, while a low-profile decorative cover (matching ceiling colors/finishes) stays visible on the surface. This design ensures it blends seamlessly with indoor decor, avoiding the visual disruption of traditional exposed sprinklers.

Engineered to meet fire safety standards, it activates automatically when ambient temperature reaches the preset threshold (typically 68℃-93℃ for general use). Once triggered, the decorative cover falls off, and the sprinkler releases water in a controlled pattern to suppress fires. It is compatible with standard fire water supply systems, available in common interface sizes (e.g., 1/2 inch) and with options for quick-response or standard-response performance, adapting to different fire risk levels in commercial, residential, and hospitality spaces.

Product Features

Concealed Aesthetic Design: Features a sophisticated concealed aesthetic design where the entire functional main body (including the valve core and spray mechanism) is fully embedded and hidden within the ceiling cavity, leaving only a slim decorative cover exposed on the ceiling surface. The decorative cover is available in a variety of materials—such as matte plastic, brushed metal, and frosted glass—and multiple color options (white, gray, black, and custom matching shades) to perfectly align with diverse interior decor styles, including modern minimalism, classic luxury, and industrial chic. This design eliminates the visual abruptness of traditional exposed sprinklers, maintaining the overall visual harmony and design integrity of spaces like high-end hotel lobbies, boutique offices, and luxury home living rooms.
Automatic Activation: Adopts a highly reliable heat-sensitive automatic activation system, with the preset trigger temperature typically calibrated to 68℃ (154.4℉) for general indoor environments (customizable to 79℃ or 93℃ for high-temperature scenarios like kitchens). The internal heat-sensitive glass bulb, filled with heat-expanding liquid, will burst instantly when the ambient temperature reaches the preset threshold, triggering the valve to open and release water immediately. This automatic response mechanism ensures that the sprinkler can initiate water discharge within 10-30 seconds of fire ignition, rapidly suppressing the spread of flames and smoke in the early stages of a fire.
Cover Release Mechanism: Equipped with a precision-engineered decorative cover release mechanism that operates in sync with the activation system. When the heat-sensitive component triggers, the built-in mechanical linkage will disengage the cover’s locking structure smoothly—without requiring additional external force—allowing the decorative cover to fall off vertically under its own weight. The release process is stable and free of jamming, ensuring that the cover does not get stuck above the spray head. This guarantees an unobstructed water spray path, enabling the sprinkler to form a full-coverage spray pattern without any interference from the detached cover.
Standard Compatibility: Complies with global fire protection pipeline standards, perfectly fitting common fire water pipe interfaces such as 1/2 inch NPT (National Pipe Thread) and BSP (British Standard Pipe) threads. The connection structure adopts a standard thread sealing design, which can be installed and tightened using conventional plumbing tools without the need for special adapters or custom components. Additionally, it is fully compatible with mainstream existing fire protection systems (including wet pipe systems and pre-action systems), supporting seamless integration into new construction projects or retrofitting of old fire protection systems, significantly reducing installation and renovation costs.
Versatile Use: Combines aesthetic appeal and fire safety performance, making it widely suitable for design-focused spaces that have high visual requirements. These include luxury hotels (lobbies, guest rooms), high-end office buildings (executive offices, reception areas), boutique shopping malls, and luxury residential properties (living rooms, bedrooms). Beyond meeting the aesthetic needs of premium spaces, it also strictly complies with international fire safety standards such as NFPA 13 (U.S.) and GB 50084 (China), passing rigorous fire performance tests to ensure it meets general fire safety requirements for various indoor scenarios.
