Ionization detectors tend to react slower, and may not warn people inside the house or commercial buildings adequately enough to be able to make it to the exit. So fire departments and legislative bodies recommended installing photo electric smoke detectors, or combination type detectors. The other feature that one may consider in a smoke detector is its gas detection capability. Incorporated in many of the newer models are carbon monoxide and carbon dioxide sensors that trigger an alarm when there is a high level of these gases present in the air. As stand alone detectors, they may be useful as alarms against dangerous gases, but may not be able to detect smoke out of ordinary fires early enough. You’ll see that these wouldn’t be good fire prevention devices if that’s what you were looking for. It is recommended that the individual homeowner find out what possible hazards could emanate from various areas of the house before deciding on what kind of smoke detector to install. And when you think about the price, most times it becomes a trivial factor especially if you have to consider that you’re actually buying protection and peace of mind. Having mentioned price, you might as well consider testing one of these so called smart smoke detectors. Some of these can be turned off by waving your arm at it in case it is accidentally set off. These smart detectors also give out a preliminary warning tone that tells you there’s smoke somewhere in the house, and gives you a chance to act.
