A method of commissioning a sensor includes using a system having a central control panel, a plurality of sensors, and a cloud server. A first identification code from a first near frequency communication (NFC) tag that identifies the control panel and a second identification code from a second NFC tag that identifies a sensor of the plurality of sensor are read and transmitted to the cloud server. A learn-in code is received from the cloud server and displayed to a user. The user is prompted to activate a learn-in process by entering the displayed learn-in code into the control panel for activating a learn-in mode at the control panel. The sensor is only enabled to communicate with the control panel if the control panel determines that the entered learn-in code matches a stored learn-in code.
