Regular smoke alarms will only do this one thing
Protecting your home from fire is a chief concern for homeowners, and smoke detectors play a critical part in shielding your family. Despite that fact, smoke detectors have their drawbacks. For instance, they will only identify smoke, not extreme temperatures. In the event there is a fire in your home, you would not be warned unless the smoke ascends to the smoke detector. Even though there are some other unmistakable signals of fire -- including a marked heat increase -- if there’s a lack of smoke, you will fail to get a sounding of your smoke detector.
In addition, smoke detectors only activate if they find ample smoke. If a fire starts small, you may not be warned until the flames are out of control. Many smoke detectors employ more than one sensor, which means they will recognize smoke from both roaring flames and smoldering remnants. Then when they do go off, it’s required of the resident to contact the fire department after safely leaving the premises.
