b.
A star configuration (going to each receiver from a central connecting point) is
sometimes more practical. Your installation will be easier to maintain and trouble-
shoot if you make all connections at a distribution block made of barrier terminals
or at a Pelco CM9760-CDU-T distribution panel (refer to Figure 12). The total
length of all control lines combined should not exceed 4,000 feet (1,219 m).
