A sprinkler head and a method for testing the sprinkler head, including an inlet device to lead fire-extinguishing medium and air from a distribution system into the sprinkler head, an outlet device to release fire-extinguishing medium and air from the sprinkler head, a flow passage to lead fire-extinguishing medium and air from the inlet device to the outlet device, a valve to be held in first non-activated state by a triggering device in the sprinkler head, so the flow passage is closed, and in activated state to open the flow passage, when the triggering device is activated in a heated state, so air and fire-extinguishing medium may flow from the inlet device to the outlet device. The valve in a second non-activated test state operatively opens the flow passage, so air and fire-extinguishing medium may flow from the inlet device through the flow passage and out through the outlet device. |
