Why use a fire sprinkler water shield?
Fire sprinklers sense heat, and each sprinkler has a specific activation temperature. But in warehouses and other locations where materials are stored on shelves or racks, sprinklers are often placed closely together. Without water shields, the cooling spray of one sprinkler may prevent the timely activation of other sprinklers nearby.
Viking's Model F-1 water shield sits at the base of an XT1 pendent fire sprinkler. These shields protect against overspray from above while leaving the space below where the sprinkler discharges open.
