Abstract

A detector for smoke, heat or the like, which has test function circuitry capable of initiating verification of the detector operation, including testing of a communication path between the detector and a central control unit. The test is actuated on receipt of a signal initiated at the detector, which indicates success by illuminating the detector's LED. An operator is able to initiate the test by means of a laser pointer.
