that are evenly distributed on the loop. Please contact your distributor for loop wire
distances for devices on an end-loaded loop.
Note: When using the tables to calculate a wire length for the VS1 panel, do not
exceed a total of 64 device addresses (any combination of detectors and modules).
In the illustration below, the longest circuit path (shown in bold lines) is 1,240 ft.
(378 m). The total amount of wire comprising the loop is 1,640 ft. (500 m)
