B. Class A, Wiring Instructions (alternate wiring methods using isolators, NFPA 72 Style 7)
Style 7 operation can be accomplished by isolating each addressable output device. The portion of the SLC
to be protected must also have a Fault Isolator Module (M-500X) at each end as shown in Figure 2-2.
NFPA 72 Style 7 wiring can only be accomplished by installing two M500X Fault Isolators close-nippled to
the single device being protected. These isolators are installed to protect the wires going to and coming from the
protected device.
•
Connect an electronic EOL device (consisting of an AMM-2 module, Address “99") (red and black wires)
to the AEU as shown in Figure 2-2. (Yellow and violet wires are not used.)
•
Be sure to observe polarity.
•
Maximum allowable field wiring resistance is 40 ohms per circuit. Use unshielded, twisted pair cable.
•
Maximum circuit capacitance is 0.5 uf.
•
Power limited, supervised

AS A SPEAKER CIRCUIT
NOTE: ONLY M500Xs AND AOM-2s USED AS SPEAKER CIRCUITS SHOWN FOR SIMPLICITY. SLC CAN ACCOMMODATE MANY MORE MODULES SUCH AS AOM-2s
USED FOR EQUIPMENT INTERLOCKS. THE USE OF M500X MODULES IS OPTIONAL AND IS ONLY REQUIRED FOR CLASS-A, STYLE-7 CIRCUITS.
