Observe maximum circuit resistance of 50 Ω.
For Class B, the total wire length of all branches connected to one
FPE-1000-SLC module (terminals S1+/SC1- and S2+/SC2-) must not exceed
30,000 feet (9140 m).
The maximum distance an analog addressable detector or module is allowed
to be located from the control panel (for Class A and Class B SLC) is limited
depending on the wire gauge; refer to Table 1.

Measuring Circuit Resistance
1.
1.
Remove the field wiring from the SLC terminals and short either the
return wire in Class A (Figure 2, Page 4, left side, Item 1 Class A) or
short the end of the farthest device in Class B (Figure 2, Page 4, right
side, Item 1 Class B) using clip leads.

short the end of the farthest device in Class B (Figure 2, Page 4, right
side, Item 1 Class B) using clip leads.
2.
Read the total resistance of all wires associated with the circuit
(Figure 2, Page 4, both sides, item 2). The maximum circuit resistance is
50 Ω.
