Honeywell NOTIFIER FireWarden-100-2 User Manual

FireWarden 100-2/E — P/N 52778:A 11/04/2005 173
Appendix D: Wire Requirements
T-tapping of the SLC loop wiring is allowed for 2-wire (Style 4) 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 NFW2-100 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 for each NFW2-100 circuit. Reference the chart below to specify wire
requirements and limitations for each NFW2-100 circuit.
Note: 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 (such
as MA/SS-24D) instead of more electronically noisy notification appliances such as
electromechanical bells or horns.
