A method and apparatus for safely and conveniently testing heat detectors mounted at an elevated location above a ground surface. A package containing a composition formulated to react exothermically but non-flammably upon exposure to ambient air sustains a temperature sufficient to activate the heat detectors under feet for a period of at least a few minutes. The package is placed in a holder supported on a long handle for raising the package into close proximity to the heat detector. After initiating the exothermic reaction, as by tearing an envelope containing the reactive composition, an operator standing on the ground under the heat detector elevates the package into contact with or close proximity to the heat detector.
