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