Abstract: A method and system of determining the location of an earth fault within a loop of devices is disclosed. Upon the detection of an earth fault within the loop comprising a plurality of devices, a first device within the loop is isolated along with a second device. While the first device and the second device are isolated, it is determined if the earth fault still exists. If the earth fault no longer exists, then determine that the earth fault is located between the first device and the second device. This can be iterated through each adjacent pair of devices in the loop to localize the earth fault between the devices.

Abstract: A fire and security system includes a control panel and one or more connected device. The control panel is in signal communication with a data control loop. The connected device is in signal communication with the at least one control panel via the at least one data control loop. The connected device includes a memory unit having a free memory area that stores first data and an active memory area that stores second data different from the first data. In response to operating the connected device according to the second data, the at least one connected device receives updated data delivered by the at least one of the control panel over the data control loop, and replaces the first data stored in the free memory data with the updated data.
