Abstract: An interface module is described for replacing a light switch assembly in an electrical switch box, the electrical switch box having an input wire coupled to a power source, an output wire coupled to a first lighting device, and at least one threaded bore. The interface module includes a housing, a first terminal mounted on the housing and connected to the input wire, a second terminal mounted on the housing and connected to the output wire, a first switch component configured to activate and deactivate the lighting device, a control configured to operate the first switch component, a user interface coupleable to the first terminal to receive operating power, and a wireless transmitter configured to transmit signals indicative of inputs received through the user interface, the wireless transmitter being configured to receive power from the first terminal.

Abstract: A method of arming or disarming a building security system includes transferring an electronic security credential file from an authorizing environment to a mobile computing device. The electronic security credential file is read by the mobile computing device to extract authentication data. The authentication data is transmitted from the mobile computing device and received at the building security system. Within the building security system, the authentication data is used to verify that a user of the mobile computing device is authorized to communicate with the building security system. The mobile computing device is enabled to communicate with the building security system only if the electronic security credential file has been used to verify that a user of the mobile computing device is authorized to communicate with the building security system.
