摘要： A concealed sprinkler can include a body that defines an outlet, a seal that seals the outlet, an activation element coupled with the seal, a housing, a cover plate, and a wall. 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 housing extends from a first housing end that extends from the body to a second housing end, and defines a chamber around the activation element. The cover plate is coupled with the second housing end. The wall extends towards the activation element to form an air flow channel to the activation element adjacent to the wall. At least one of the cover plate and the wall are removably coupled with the body.
