Residential High Concealment Fire Sprinkler Head for Brass Forest Fire Fighting Equipment

 

Product Description

Product Description

The glass bulb sprinkler head is an important component of a sprinkler system,  the mechanism is that the
glass bulb is sensitive to heat, when the surroundings temperature reaches a certain point,   the glass bulb
will break and activate the sprinkler to spray water for fire extinguishing. 

The concealed sprinkler head is usually installed at places with luxurious decoration and beautiful appearance,
such as antechamber, meeting room, shopping mall, hotel, and recreational center, etc. It can be concealed
in the ceiling completely. The color of the cover plate can match with ceiling to make the installed hole
hue harmonious.



Introduction:
Sprinkler is an important part of wet-type auto spraying system. It is usually installed inside the building and structures with light fire danger, medium fire danger and heavy fire danger, such as workshop, warehouse, hotel, shop, recreational place, hospital, cinema, office building and garage.
The sprinkler is composed of sprinkler frame, sealant and glass bulb. It is to be installed in the protective district via ductwork, acting as a fire detector and auto sprayer. In case of fire inside the protective district, the atmosphere temperature rises up and the liquid inside the glass bulb expands after being heated and explodes after reaching the operating temperature of the glass ball. The sealant drops and the sprinkler sprays to the protective district for fire extinguishments subject to the preset shape of spraying.

      1. The installation distance of the spray head is generally 3.6 meters in diameter and 1.8 meters
      in radius;
      2. The maximum protection area of the sprinkler is 12.5 square;
      3. The spray head should not be less than 300mm from the wall;
      4. When the distance between the spray head and the ceiling is greater than 80m, and there
      are combustibles in the ceiling, the    upper and lower sprays are required.   

FAQ:
1. What is a High Concealment Fire Sprinkler Head?
A High Concealment Fire Sprinkler Head is a specialized fire protection device designed to be discreetly integrated into ceilings or walls. It features a concealed cover plate (typically paintable) that blends with the interior décor until activated by heat, at which point the cover drops away and the sprinkler operates.

2. Can you customize the product for our brand?
Absolutely. We offer OEM/ODM services including:

Private labeling and custom packaging

Custom finishes and colors

Modifications to meet specific project standards

Custom temperature ratings and orifice sizes.


3. What temperature ratings are available?
Standard ratings include:

Ordinary Temperature: 68°C / 155°F (Orange bulb)

Intermediate Temperature: 79°C / 174°F (Yellow bulb)

High Temperature: 93°C / 200°F (Green bulb)

Extra High Temperature: 141°C / 286°F (Blue bulb)
Custom ratings can be discussed for OEM projects.

4. What types of finishes and colors are available?
Concealment Cover: Standard white primer (paintable to match any décor)

Escutcheon Plate: Chrome, brass, bronze, black, white, or custom powder-coated finishes

Custom Colors: Available for large OEM orders with specific RAL or Pantone codes

5. How is the concealment cover activated?
The cover is held in place by a heat-sensitive solder pellet or glass bulb. When the ambient temperature reaches the rated level, the solder melts or the bulb shatters, causing the cover plate to detach and fall away. This then allows the sprinkler's heat-responsive element (fusible link or bulb) to activate and release water.

6. Are these suitable for residential and commercial use?
Yes. High concealment sprinklers are ideal for:

Commercial Spaces: Hotels, offices, retail stores, galleries

Residential Buildings: Luxury apartments, condominiums, private homes

Institutional Facilities: Hospitals, schools, museums
Anywhere aesthetics are a priority without compromising safety.

7. What is the installation requirement?
Requires a recessed mounting cup or fitting installed flush with the ceiling/wall.

Must be installed by a qualified professional according to NFPA 13 or local fire codes.

Adequate clearance around the sprinkler (as per installation instructions) must be maintained.

8. Can the cover plate be painted?
Yes. The standard primer-coated cover plate is designed to be painted on-site with standard latex or oil-based paints to match the ceiling color perfectly. Painting does not affect its thermal activation performance.

9. What is the response time compared to standard sprinklers?
The concealment cover adds a minimal, tested delay. Our products are designed and certified to meet the same response time indices (RTI) as standard exposed sprinklers for their respective temperature ratings, ensuring no compromise in fire response performance.

10. What is your lead time and MOQ?
Standard Models: 30-45 days for production; MOQ is typically 500-1000 pieces.

Custom OEM Orders: 60-90 days for tooling and production; MOQ negotiable based on design.
