Abstract

A device for testing smoke detector alarms comprises a base housing upon which is mounted an extendable telescopic assembly comprising three tubes, with the top tube having a combustible pellet mounted at its upper end. The pellet is composed of a substance that smolders upon heating rather than flaming or exploding. The housing contains electrical batteries wired in circuit with a heating element mounted adjacent the combustible pellet so that a switch can be operated to heat the heating element and cause the pellet to smolder so that smoke emerges from the pellet. The testing device can be placed in the extended position and the pellet held near a smoke detector and burned to ascertain whether the smoke detector alarm is functioning properly. After use the testing device can be placed in a compact storage position by sliding the extendable telescopic tubes so that they fit within each other. If desired, the assembly upon which the pellet is mounted can comprise a unitary tubular section rather than a movable section.
