that circuit. The relay can be installed in line with any leg (+ or –) of the supervised NAC or IDC circuit, either a two- or a four-wire
style.
Figure A.1 shows Class B supervision of a 24VDC circuit using the FCM-1 or FZM-1. Refer to the Device Compatibility Document for
compatible notification appliances and relays.
Figure A.2 shows an alternate Class B method of supervising a 24VDC circuit using a control module that is fully powered from the
SLC loop.
