The electrical characteristics of the photocell (C1) are monitored by a device which supplies a corresponding signal to a voltage level detector (N), connected to a trigger circuit for an alarm (A) to operate the latter when the photocell indicates a given smoke concentration. An RC network...
Most smoke detectors are equipped with a "test" button. Alternatively, artificial smoke can be purchased, which has the advantage of also testing the detector itself. Many people simply wave a lit match underneath the detector to test it, however this is dangerous as it can set the smoke al...
