How quickly will my Lyric app receive a smoke or carbon monoxide (CO) alarm alert?

Once the Lyric C1 and C2 camera hears the beeping smoke or CO detector, it triggers the alert. The email and in-app notification are then sent within 3-5 minutes, depending on the home WiFi network and other network parameters such as the signal strength in your smart device and the broadband bandwidth offered by your home Internet Service Provider (ISP) network.
