2-in-1 hardwired smoke and carbon monoxide alarm alerts you to both types of danger in your home, with a photoelectric smoke sensor and electrochemical carbon monoxide sensor
Alarm sends emergency notifications via your phone, while voice alerts tell you the type and location of danger
Interconnects with 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; works with Amazon Alexa so you can ask Alexa to check the status of your Onelink alarm (Alexa device sold separately).
Hardwired alarm includes a 10-year sealed battery backup for protection in power outages; for maximum protection, hardwired alarms should be installed on every level of the home and inside each sleeping area
Compatible with Apple HomeKit; can be used on both Apple and Android devices
