Statistics have shown that three out of every five fire outbreaks could have been prevented by a working smoke detector. What this indicates is that a smoke detector in your home cuts down the chances of a fire outbreak in half. Of course, there is a lot more to smoke detectors than just statistics. Of the numerous types we have, some are Ionized types, other dual sensors and some more are photoelectric
While each smoke detector type has its advantages and disadvantages, it is one of the criteria we consider when buying one. Amongst others, interconnectivity, power source, lights, digital display, and alarms all play important roles. Depending on your priorities, budget, and preference, our list may be an ideal fit for your research needs.
