SLC Wiring with MMX Monitor Modules
Refer to the Device Compat-
ibility Document 15378 for
detector and power supervi-
sion relays.
You can install MMX-1 modules in an SLC loop as shown in the wiring
diagram. Maximum initiating device circuit resistance is 20 ohms. The
wiring diagram below shows typical MMX-1 wiring for a supervised and
power limited NFPA Style D initiating device circuit. The following table
contains SLC wiring connections to the MPS-400 and the CPU-400.
