Once the batteries are inserted, the Water Leak + Freeze Detector will go into wireless setup mode for five minutes, to connect with the Kidde app on your smartphone for configuration. If you do not follow the setup process within that time frame, the detector will simply function like a normal water leak sensor and sound audible alerts to water events and temperature drops, but will not provide any smart features, like mobile notifications.
If you miss that 5-minute window, reset the detector’s wireless settings:
- Option 1 (wireless reset): Remove the batteries, wait thirty seconds, re-install the batteries.
- Option 2 (full reset): Using a metal screwdriver or paper clip, apply a direct short to the two metal contacts on the bottom of the device three times within two seconds.
Either of these methods will reset the device and cause it to automatically search for a wireless connection.
