Abstract:
A method for testing a heat detector having a heat sensor and mounted at an elevated location above a ground surface, comprising the steps of:providing a composition formulated to react exothermically but non-flammably and to release steam upon being wetted so as to sustain a temperature sufficient to activate the heat detector under test;wetting said composition to initiate an exothermic reaction; andelevating said composition into contact with or sufficient proximity to an underside of said heat detector to expose said heat sensor to heat and steam produced by the exothermic reaction without intervening heat insulation and steam barriers between said composition and said heat detector thereby to permit both heat and steam rising from said composition to reach the heat sensor of the detector such that heat is more effectively delivered to the heat sensor by contact thereof with steam from the exothermic reaction.
