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 FACP 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 FACP circuit.  Reference the chart below to specify wire requirements and 
limitations for each FACP 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. If two SLC loops are to be installed in conduit, each loop must be installed in separate conduit.
3. The SLC can be programmed to operate in LiteSpeed mode (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:
