Time to time the product firmware or app may have an update from us at Onelink by First Alert.
App updates will come through the iTunes store as any other update available for download and installation.
You will receive a notification for any product firmware updates. If you miss the notification, the app also has the capability to identify appropriate updates that may be available for you to download. Simply navigate to each alarm setting screen within the Onelink Home app and look for the Firmware section. If an appropriate update is available, the check for updates option will be available in this section. If an update is available, simply follow the instructions in the app.
