Wiring SLC Devices in Style 6 & 7 (Class A) Configuration
Figure 2.10 illustrates how to wire the SLC loop for Style 6 or Style 7 Class A installations.
NOTE: Style 6 does not require the use of short circuit isolator devices.
Wires must be in conduit and close-nippled if isolator modules are used.

!
FOR PROPER SYSTEM SUPERVISION DO NOT USE LOOPED WIRE UNDER TERMINALS
MARKED SLC + AND – OF THE SLC DEVICE CONNECTORS. BREAK WIRE RUNS TO PROVIDE
SUPERVISION OF CONNECTIONS.
2.7.4 Addressing MMF-301 SLC Devices
All MMF-301 devices are addressed using the two rotary dials that appear on the device board. Use
the ONES rotary dial to set the ones place in a one or two digit number, and use the TENS rotary
dial to set the tens place in a two digit number.
MMF-301 modules can be assigned any unique address from 1 to 24.
