Appendix B: Wiring Requirements - Honeywell NOTIFIER NFC-50/100 Instruction Manual

Connecting external system accessories to the NFC-50/100 main circuits must be carefully considered 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 limitations.
NOTE: If an SLC loop is to be run in conduit with NFC-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.
