How to Test a Silent Knight Smoke Detector

Smoke detectors play an important part in ensuring the safety of your home and family. It is wise to have a well-maintained, working smoke detector in every part of the house or workplace. Test your smoke detectors regularly to make sure that they are in good working order. Silent Knight brand (a division of Honeywell) smoke sensors have three different testing mechanisms--canned smoke, specially calibrated test magnets, and direct heat. Direct heat is the simplest method, and its one that you can do yourself if you have a hairdryer.
