From The Manufacturer

The First Alert Onelink 2-in-1 smart smoke and carbon monoxide alarm alerts you to both types of danger in your home. Emergency notifications alert you to danger via your phone, while voice and location technology tell you the type and area of danger; the alarm also uses a traditional 85-decibel siren. Onelink interconnects with other existing traditional hardwired alarms and other Onelink devices (sold separately) to create a smart home safety network, so if one alarm sounds, they all sound. This alarm is also compatible with Amazon Alexa; you can ask Alexa to check the status of your Onelink alarm. The Onelink Home App is compatible with both Android and iOS devices. This easy-install hardwired alarm includes an adapter plug so you don’t need to rewire, and a 10-year sealed battery backup for protection in power outages. The alarm is designed to last for 10 years, and will alert you when it needs to be replaced.
