Notes:
1.
Refer to Table 3 for maximum RAC wiring distance based on 0.6 V Drop, including supervision module. 0.6 V Drop per
Releasing Appliance Circuit (RAC) Output Interface description is on page 5 and Table 3. RAC wiring is class B only.
2.
When connecting two wires to one terminal, position one wire on each side of the terminal screw.
3.
IDNet, NAC, and RAC lines are 18 AWG (minimum) to 12 AWG (maximum).
4.
Refer to the appropriate FACP instructions for IDNet and NAC wiring guidelines.
