The WFDN Series Waterflow Detector is fully redesigned to meet the needs of modern fire sprinklers. The new timer dial has a built-in time delay that is large and easy to turn with high-contrast, pad-printed markings and tactile features to make it easy to set by feel in dimly lit or hard-to-reach locations. The detector’s built-in time delay mechanism is reportedly immune to dust and other contaminants and is designed for improved timer accuracy and repeatability. The new non-metallic directional cover material is UV- and damage-resistant, and it helps provide a better seal while maintaining a NEMA 4 enclosure rating. The cover also acts as an insulator, resists corrosion and arching, and resists damage and electric shock more effectively than current metal designs on the market.
