SLC Wiring with MMX Monitor Modules
MMX-1 Wiring an NFPA
Style B Initiating Device
Circuit
You can install MMX-1 modules in an SLC loop as shown in the wiring
diagram. Maximum initiating device circuit resistance is 20 ohms. SLC
wiring connections to the MPS-400 and CPU-400 follow:
Refer to the Device Compat-
ibility Document 15378 for
detector and power supervi-
sion relays.
