Regular smoke alarms can only do this one thing
Defending against fire is a crucial consideration, and smoke detectors take on a vital part in shielding your family. Despite that fact, smoke detectors have various drawbacks. For example, they will only identify smoke, not high temps. In the event there is a fire in your house, you might not be cautioned unless the smoke ascends to the smoke detector. While there are additional significant signals of fire -- such as a sudden increase in warmth -- if there's no smoke, you will fail to get a triggered smoke detector.
What’s more, smoke detectors only sound the alarm when they find enough smoke. If a fire begins slowly, you might not be warned until it's too late. Many smoke detectors utilize more than one sensor, which means they will recognize smoke from both roaring flames and a more gradual burn. Then when they sound their alarm, it falls to the homeowner to call first responders after safely leaving the property.
