A device for testing rate of rise heat detectors, smoke detectors and smoke alarms consisting of a body having a first end, a second end and an interior cavity. The first end is adapted to fit over a detector or alarm. A divider is disposed within the interior cavity of the body thereby dividing the interior cavity into a first portion adjacent the first end and a second portion adjacent the second end. The divider is heated from a heat source disposed in the second portion of the interior cavity, this indirectly heats the first portion of the interior cavity thereby facilitating testing of detectors sensitive to heat. A reservoir adapted to receive powder is attached to the body. A powder passage extends from the powder reservoir to the first portion of the interior cavity adjacent the divider. An air bellows is provided for blowing powder from the powder reservoir through the powder passage into the first portion of the interior cavity. The powder generates smoke upon contact with the heated divider thereby facilitating testing of detectors sensitive to smoke.
