Abstract
A fire protection sprinkler is provided with a skipping shield having air flow passages therethrough to reduce the negative impact that the shield has on the thermal response of the sprinkler. By providing holes, slots, louvers, or mesh to the skipping shield, water from adjacent flowing sprinklers can still be blocked from impinging on the thermal element. The shield will block water but allow hot gas from the fire to flow through the shield thereby improving the response time of the thermal element.
