UL Standard & Quick Response Concealed Fire Sprinkler

Concealed fire sprinkler heads not only enhance the aesthetic appeal of buildings but also play a vital role in fire protection. A key distinction in understanding their performance lies between "standard response" and "fast response" types.

Product Introduction

The nozzle body is entirely concealed above the ceiling, leaving only the edge of the sleeve level with the ceiling surface. A decorative cover plate is positioned at the sleeve's opening, harmonizing in color and texture with the ceiling to ensure total visual integration. As with all wet fire protection systems, the pipes that connect the sprinkler bodies are perpetually filled with pressurized water, standing ready to respond at a moment's notice.

When a fire breaks out indoors, the heat generated by the high-temperature smoke and flames will accumulate beneath the ceiling. The fusible alloy solder between the decorative cover plate and the sleeve melts at its specific melting point temperature (typically 135°F / 57°C or 165°F / 74°C, etc.). After the solder melts, the decorative cover plate, which has lost its adhesive force, will automatically fall down under the effect of Earth's gravity, exposing the nozzle body and the splash tray hidden above the ceiling.

The thermal-sensitive component of the nozzle, typically a glass bulb, is exposed to hot air and absorbs heat rapidly. As the temperature rises, the liquid within the glass bulb expands, leading to a potential rupture; if the component is made of a fusible alloy, it will simply melt and detach. This rupture or disconnection of the thermal-sensitive element results in the loss of support for the seal (the water valve disc) that it previously maintained. Consequently, the pressurized water within the pipe bursts through the compromised seal and sprays out from the nozzle. The resulting water flow strikes the splash pan, where it is evenly distributed into specific droplet formations, effectively covering the ground within the designated protected area and thus achieving fire suppression or control.

Product Features

• Aesthetics: The greatest advantage is that it does not affect the interior decoration design style.

• Protect the nozzle: Avoid accidental impact or damage to the nozzle in daily use.

The concealed sprinkler heads operate on a clever principle that seamlessly merges aesthetic appeal with fire-fighting capabilities. Their functionality is based on a two-stage triggering mechanism: first, the cover plate drops, followed by the shattering of a glass bubble. This design ensures dependable activation at critical moments, offering a safe and visually appealing fire protection solution for contemporary architecture.
