Mô tả sản phẩm

The A2-65 Combined Alarm Check Valve is a UL Listed and FM Approved fire protection valve specifically designed for wet pipe automatic sprinkler systems. Manufactured by PARATECH Korea under the Fesco brand, the valve combines the functions of an alarm check valve and an alarm switch into a single integrated assembly, providing dependable water control and automatic fire alarm activation.

During normal operation, the valve prevents reverse water flow while maintaining system readiness. When one or more sprinkler heads operate during a fire, water flowing through the valve activates the integrated alarm switch, transmitting an electrical signal to the building fire alarm system while simultaneously allowing water to reach the sprinkler network for immediate fire suppression.

The A2-65 Combined is available with flanged or grooved connections in DN65, DN80, DN100, DN125, DN150, and DN200 sizes, making it suitable for a wide range of commercial, residential, and industrial fire protection systems. Its compact design simplifies installation while reducing the number of separate components required in the alarm valve assembly.

Designed to comply with internationally recognized UL and FM standards, the valve provides reliable hydraulic performance, long service life, and dependable alarm operation under demanding fire protection conditions. Its robust construction minimizes maintenance requirements while ensuring rapid system response whenever sprinkler activation occurs.

The A2-65 Combined Alarm Check Valve is widely used in office buildings, shopping malls, hospitals, hotels, manufacturing facilities, warehouses, airports, data centers, residential high-rise buildings, and industrial plants, where dependable automatic fire sprinkler protection is essential.

Since 1973, when Korea's fire protection industry was still in its infancy, Paradise Industry, now known as PARATECH, has operated under the corporate philosophy of "contributing to society by protecting lives and property from fire." The company obtained more than 20 national certifications for its fire protection products, including automatic fire sprinklers, and became the first manufacturer to supply these products in Korea.
