First Alert/Onelink Hardwired Smart Smoke + CO Alarm
- 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 an adapter plug so you don’t need to rewire, 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
