SPRINKLER PENDANT

Specifications

1. Design and Structure
   • Pendant Style: The sprinkler pendant has a downward-facing design, allowing for effective coverage and water dispersion over a larger area of the floor or room.
   • Material: Typically made of brass, stainless steel, or chromed metal, ensuring corrosion resistance and durability in various environmental conditions.
   • Shape and Size: Standard sizes typically range from 1/2 inch to 3/4 inch in diameter, but custom sizes are available for specific applications.
   • Finish: Sprinkler pendants often feature a chrome-plated or painted finish for aesthetic purposes and enhanced durability. Special finishes can be chosen for design preferences and environmental factors.
   • Ceiling Mounting: Designed for ceiling installations, often mounted in suspended ceiling grids, ceilings with tile, or open spaces in commercial and industrial buildings.
2. Activation Mechanism
   • Thermal Element Activation: The sprinkler pendant uses a heat-sensitive element (such as a glass bulb or fusible link) that melts at a specific temperature, triggering water release when the surrounding temperature rises due to a fire.
     • Glass Bulb: Filled with a colored liquid that expands and breaks the bulb when the set temperature is reached (commonly 68°C, 93°C, 141°C, or 182°C depending on the application).
     • Fusible Link: A metal link that melts when the set temperature is reached, causing the sprinkler head to activate.
   • Response Time: The quick response feature ensures that the sprinkler pendant activates rapidly to suppress fires before they spread.
3. Water Distribution
   • Flow Rate: The standard flow rate for a sprinkler pendant is typically between 13-15 liters per minute (LPM) per head, depending on the model and system design. Some models allow for higher flow rates based on system requirements.
   • Spray Pattern: Designed for uniform water dispersion, the sprinkler pendant typically features a deflector plate to create an even distribution of water over the fire area.
   • Coverage Area: Typically covers an area of 8 to 16 square meters (85 to 170 square feet) per pendant, depending on the sprinkler system’s design and building layout.
4. Durability and Environmental Resistance
   • Corrosion Resistance: Most sprinkler pendants are built with materials like stainless steel or brass to withstand harsh environments, including moisture, chemicals, and high-humidity areas.
   • Heat Resistance: Designed to endure high temperatures, sprinkler pendants function optimally even in environments with extreme heat.
   • Seismic Resistance: Many models are engineered to meet seismic requirements, ensuring reliable performance in areas prone to earthquakes or other structural stresses.
5. Installation and Maintenance
   • Easy Installation: Designed for simple installation with standard threading or bracket mounting. Compatible with a variety of fire sprinkler systems, including wet, dry, and pre-action systems.
   • Maintenance-Free: Sprinkler pendants require minimal maintenance. However, regular inspections are recommended to ensure the heat-sensitive element and spray pattern function properly.
   • Flow Test and Testing: Periodic testing, including hydrostatic tests and flow tests, should be performed to check the system’s integrity and performance.
6. Compliance and Standards
   • UL Listed: Most sprinkler pendants are UL Listed, meeting Underwriters Laboratories standards for fire protection and safety.
   • FM Approved: Some models are approved by Factory Mutual for use in industrial applications.
   • NFPA Compliant: Complies with National Fire Protection Association (NFPA) standards for sprinkler systems, such as NFPA 13 for residential and commercial fire sprinklers.
   • EN 12259: Conforms to European standards for sprinkler system components, ensuring safety and efficiency in European regions.
7. Applications
   • Commercial Buildings: Ideal for offices, retail spaces, schools, hotels, and shopping centers, where aesthetic and effective fire protection is essential.
   • Industrial Facilities: Suitable for warehouses, manufacturing plants, and factories where high-risk areas must be covered by fire suppression systems.
   • Residential Spaces: Used in apartment buildings, residential complexes, and multi-family housing units to ensure occupant safety in case of fire.
   • Hospitals and Healthcare Facilities: Provides life-saving protection in sensitive environments where fire safety is crucial.
   • Restaurants and Kitchens: Commonly installed in commercial kitchens to protect against fires caused by cooking equipment.
