Production introduction
The foinbo® brand Extended coverage (EC) sprinkler heads represent a significant advancement in fire suppression technology, designed to protect larger areas than traditional sprinklers while maintaining reliable performance. By leveraging innovative nozzle designs, optimized water distribution patterns, and higher pressure ratings, these sprinklers reduce the number of heads required in a system, lowering installation costs and minimizing aesthetic disruption. Commonly used in warehouses, retail spaces, and open-plan facilities, EC sprinklers are engineered to meet stringent safety standards while addressing modern architectural and operational demands.
Extended coverage sprinklers are specialized fire protection devices engineered to safeguard expansive areas-typically up to 20 feet by 20 feet (6m x 6m) per head under standard conditions, compared to 12 feet by 12 feet (3.7m x 3.7m) for conventional sprinklers. Their design focuses on two key innovations:
- Optimized Deflectors: The deflector (the component that shapes water into a spray pattern) is tailored to distribute droplets evenly across a wider radius, ensuring uniform coverage even at greater distances.
- Higher K-Factors: EC sprinklers often feature larger orifice sizes (higher K-factors), enabling them to discharge more water at higher pressures, compensating for the increased coverage area.

FAQ
Q: What is an Extended Coverage (EC) Sprinkler Head?
A: An EC sprinkler head is designed to protect larger areas (up to 20 ft × 20 ft) than standard sprinklers by optimizing water distribution patterns and pressure ratings.
Q: How does an EC sprinkler differ from a standard sprinkler?
A: EC sprinklers use specialized deflectors and higher K-factors to achieve wider coverage, reducing the number of heads required in a system.
Q: What is the maximum coverage area for an EC sprinkler?
A: Typically up to 400 sq ft (37.2 m²) under standard conditions, depending on hazard classification and ceiling height.
Q: What triggers the activation of an EC sprinkler?
A: Like standard sprinklers, EC heads activate via a thermal element (glass bulb or fusible link) that responds to heat from a fire.
Q: Are EC sprinklers suitable for all building types?
A: No-they are primarily used in light/ordinary hazard occupancies (e.g., warehouses, retail stores) and require compliance with NFPA 13 or local codes.
