156 MS-9600 PN 51335:E 7/9/03
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-9600 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-9600 circuit. Reference the chart below to specify wire requirements and
limitations for each MS-9600 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.
