Appendix D: Wire Requirements - Honeywell Notifier NFW-100X Manual

T-tapping of the SLC loop wiring is allowed for 2-wire (Class B) configurations. The total resistance of any branch cannot exceed 40
ohms. The total wire length of all branches cannot exceed 10,000 feet (3,000 m).
Connecting external system accessories to the NFW-100X main circuits must be carefully considered to ensure proper operation. It is
important to use the correct type of wire, gauge and run length for each NFW-100X circuit. Reference the chart below to specify wire
requirements and limitations for each NFW-100X circuit.
Note:
1. If the SLC loop is to be run in conduit with Notification Appliance Circuits, the risk of encountering problems can be greatly
reduced by exclusively employing electronic sounders instead of more electronically noisy notification appliances such as
electromechanical bells or horns.
2. The SLC can be programmed to operate in FlashScan mode (displayed as "LiteSpeed", factory default setting) for a quicker device
response time. While shielded wire is not required in LiteSpeed mode, it is recommended that all SLC wiring be twisted-pair to
minimize the effects of electrical interference. Use the following table to determine the specific wiring requirements for the SLC
when unshielded wire is used:
Refer to Table D.1 on page 142 and Table D.2 on page 143 for wiring requirements.
