Appendix B: Wiring Requirements

Connecting external system accessories to the ECC-50/100 main circuits must be carefully consid-
ered 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 limita-
tions.
NOTE: If an SLC loop is to be run in conduit with ECC-50/100 Notification Appliance Circuits, the
risk of encountering problems can be greatly reduced by using twisted, shielded cable on the SLC
and NACs.

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.
NOTE: Wire to wire short circuit trouble = zero ohms.
Open circuit trouble = infinite ohms.
Ground fault trouble = zero ohms to ground.
