include using an application on a mobile device to establish first wireless communications with a first hazard detector that was previously paired with the user account. The method may also include transmitting, to the first hazard detector and using the first wireless protocol, a transmission that instructs the first hazard detector to establish second wireless communications with a second hazard detector, where the second wireless communications use a second wireless protocol. The method may additionally include transmitting network credentials to the first hazard detector using the first wireless protocol, where the credentials are then sent from the first hazard detector to the second hazard detector using the second wireless protocol, such that the second hazard detector can pair with the user account using the first wireless protocol.
