Smoke detectors can come in many different flavors. Some of the simple smoke detectors available don’t come with any special functions. They are affordable and don’t require anything more than a standard battery to operate reliably.
After ten years you would simply dispose of the device and replace it with a new one.
More complex smoke detectors can be wireless interconnected. That means that all smoke detectors will sound an alarm when just one of them in your home detects smoke or fire. This can be extremely useful if you have detectors installed in remote rooms in your home. This can benefit your home’s and family’s safety greatly!
Even more advanced models can send an alarm to your phone or even automatically summon the fire brigade.
Some smoke detectors can be combined devices. Those detectors can not just alert in case of smoke and fire but they also have sensors for carbon monoxide.
Modern fire alarms, smoke detectors and fire extinguishers can increase your home’s safety and security for very little money.
