burglar alarms
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.
