Product's highlights

For complete home security, this smart alarm can detect both smoke and carbon monoxide. An app on your phone lets you test the alarm, check the alarm's status and battery life, stop false alarms, and more.

It does feature a 9V battery backup, which is a crucial safety measure, in case the power goes out. All of the system's alarms activate when one of them detects smoke or carbon monoxide.

Frequently Asked Questions

1. How do smoke alarms function?

Ionization smoke alarms are more sensitive to enormous flames because they include a small amount of radioactive material that ionizes the air around them. Ion flow is disrupted and the alarm is set off when smoke enters the chamber. On the other hand, photoelectric alarms react well to smoldering fires. 3 A light sensor is used by this kind of alarm to operate. When smoke enters a sensor chamber, light from a source inside the chamber is reflected, signaling the alarm. You can never tell what kind of fire you could have, therefore for maximum safety, your home should always have both types of protection.

2. How is a smoke detector battery changed?

You must first take off the cover in order to replace the smoke alarm's battery. The majority of covers twist open, although some require the use of a screwdriver. According to your model, your user's manual should provide specific instructions, and most of them are simple to adjust once you've taken off the cover. Simply unplug the previous battery (many people use 9V or AA batteries, although other people use lithium) and install the new one. Ensure that it is firmly in place and facing the appropriate direction.

After replacing the battery, use the test button to make sure it was installed properly. Battery positioning could be the cause of the test alarm not going off.

3. Do I need a lot of smoke detectors?

Every level of your home, including the basement, should have a smoke alarm.

Smoke alarms are the quickest way to detect fire and stop it from spreading to other areas of the house, therefore you should have one outside every sleeping space and one in each bedroom. You can still install additional battery-operated alarms throughout the house even if your house already has a certain number of hardwired ones. It is preferable to have more alarms than not enough when it comes to preventing fires.

Final Thought

Smoke detectors don't appear to receive the same attention as home security systems, and this can be a costly error for something that is so crucial to home and personal safety. According to NFPA, having smoke alarms can reduce the risk of dying in a house fire by 55%.
