Will the home safety and security devices you invested in continue working to keep you safe?

Don’t worry, we’ve got you covered. This list of specific models and brands of home safety and security products have a “plan B” power backup in place in case there’s no access to electricity for a period of time, whether that be from a blizzard, blackout, summer storm, or other event.

It is easy to install—simply plug it into a standard 120V outlet in your home. The digital LED display shows the level of carbon monoxide and an 85-decibel alarm announces when carbon monoxide is detected.
