Appendix C: Wiring Requirements
Connecting external system accessories to the ACC-25/50DA main circuits must be carefully con-
sidered to ensure proper operation. It is important to use the correct type of wire, wire gauge and
wire run length per each circuit. Refer to the following table to specify wire requirements and lim-
itations.
NOTE: If an SLC loop is to be run in conduit with ACC-25/50DA Notification Appliance Circuits,
the risk of encountering problems can be greatly reduced by using twisted, shielded cable on the
SLC and NACs.

Table C.1 Distributed Audio Panel Wiring Requirements
1 Refer to NEC Standards.
2 Twisted, shielded wire is recommended for maximum protection against EMI and AFI emissions and
susceptibility.
3 Must also meet NFPA 72 Standards for minimum and maximum sound levels.
