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 MS-9200UDLS 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 MS-9200UDLS circuit.  Reference the 
chart below to specify wire requirements and limitations for each MS-9200UDLS 
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.
