Hardware Installation—Installing the IFC-1010/2020
131
The application provided in Figure 92 is not suitable for separate
transmission of sprinkler supervisory signals. All circuits are supervised
and power limited. 18 AWG (0.75 mm
2
) is the minimum. There is a
maximum loop resistance of 40 ohms for the LIB-200. The maximum
distance between the Central Station/Receiving Unit and the M50xMJs is
10,000 feet at 12 AWG (3.25 mm
2
) for the LIB-200. For initiating device
connections, refer to Figure 65 and Figure 69.
