Type:

• Concealed fire sprinkler heads (for ceiling installation)

Function:

• Designed to activate during a fire by releasing water when the temperature exceeds the rated threshold
• Provides fire suppression while maintaining a clean, aesthetic ceiling appearance

Design:

• Concealed Cover Plate:
  • Remains flush with the ceiling when not activated
  • Provides a sleek and unobtrusive look
• Activation:
  • Heat-sensitive element (typically a fusible link or heat-sensitive glass bulb) triggers the release of the sprinkler cover when the temperature reaches a specified limit

Temperature Ratings:

• Common Activation Temperatures:
  • 135°F (57°C)
  • 155°F (68°C)
  • 175°F (79°C)
• Other temperature options may be available depending on the application and environment

Flow Rate:

• Typically between 13 to 25 GPM (gallons per minute) depending on the sprinkler model and pressure

Water Pressure:

• Designed to operate at a standard water pressure range of 7 to 15 bar (100-220 PSI) depending on the specific model

Coverage Area:

• Covers an area of up to 225 square feet (depending on the design and specifications of the sprinkler system)
• Suitable for residential, commercial, and industrial applications

Material:

• Body Material: Stainless steel, bronze, or other corrosion-resistant materials
• Cover Plate: Typically made of metal or plastic with a painted or chrome finish

Mounting Style:

• Recessed Mount: Installed within the ceiling, leaving only the concealed cover plate visible
• Can be mounted on various ceiling types, including drop ceilings, drywall, or plaster

• UL (Underwriters Laboratories) listed for fire protection
• Complies with NFPA (National Fire Protection Association) standards
• Meets local building code requirements and insurance specifications

Sprinkler Types Available:

• Standard Response: Activates within a shorter time frame (typically faster response in fires)
• Quick Response: Designed for quicker activation, suitable for residential and commercial areas where a rapid response is needed
• Extended Coverage: Ideal for large open areas or spaces that require greater coverage

Size:

• Thread Sizes: Commonly 1/2-inch or 3/4-inch NPT (National Pipe Thread) connections
• Dimensions: Varies based on model, but typically 1.5 to 3 inches in diameter for the sprinkler head
• Cover Plate Dimensions: Typically 3 to 4 inches in diameter

Sprinkler Head Activation Time:

• Typically within 3-5 minutes after activation, depending on the surrounding temperature and the sprinkler’s specific temperature rating

Maintenance:

• Low maintenance, but must be regularly inspected for dust or debris that could affect performance
• Cover plates are often designed for easy replacement if damaged
