An apparatus for testing a smoking or fire detector includes an open-topped housing for receiving a detector under test. A stream of fluid for activating the detector is generated in a portion of the housing below the detector and is directed by a duct up one side of the interior of the housing to flow across the housing in a direction of the detector. A spacer can be provided in order to ensure that the direction of flow is precisely located at a point that is a predetermined distance above the bottom of the detector. Also, a heating element may be provided in the duct if required. |
