    摘要： A system and method for commissioning safety devices is disclosed. The method includes providing one or more safety devices configured to generate a signal responsive to detection of a hazard. The one or more safety devices are communicably coupled to each other via first and second communication networks. The method further includes receiving, by a controller, at any one of the one or more safety devices, a first data packet including attributes pertaining to commissioning of the one safety device. The method further includes transmitting, by the controller, the first data packet to the remaining safety devices of the one or more safety devices through the first communication network. The method further includes receiving, by the remaining safety devices of the one or more safety devices, the first data packet to enable respective commissioning of the remaining safety devices.
