Summary:A concealed sprinkler includes a body that defines an outlet, a seal that seals the outlet, an activation element coupled with the seal, a housing that defines a chamber around the activation element, a cover plate removably coupled with the housing, and a wall coupled with or extending from the cover plate to direct air flow to the activation element. The activation element changes from a first state to a second state responsive to a fire condition to allow the seal to be displaced from the outlet. The cover plate is removably coupled with the housing such that a duration of time between decoupling of the cover plate from the housing responsive to the fire condition and changing of the activation element from the first state to the second state responsive to the fire condition is less than a threshold duration of time.
