Selecting The Right Smoke Detector
Even the smallest of house fires can fill your home with dangerous smoke in a matter of. it is important that you purchase the correct smoke detectors, follow the installation instructions and have them properly tested on a regular basis.
residential smoke detectors come in two types, one is photoelectric, and the other is an ionization detector. In a photoelectric detector a beam of light is aimed into a chamber containing a photocell. Smoke entering the chamber will scatter the light, enabling some of it to reach the photocell and cause an alarm. A smoldering fire will set off a photoelectric detector quicker than a flaming fire.
