Wire Length
Tables
Table 2 and Table 3 show the maximum wire lengths possible for the power wiring. Table 4 and
Table 5 show the maximum wire lengths for the communication wiring.
•
When using multiple annunciators and runs, the total of all runs must not exceed 10,000 feet
(304.8 m, including T-Taps).
•
Four 2081-9044 Overvoltage Protectors are the maximum number permitted on any single
communication loop.
