SLC Wiring with CMX Control Modules
When an MPS-400 Notification Appliance Circuit supplies power to CMX mod-
ules:
1) The CMX module outputs are coded if the MPS-400 Notification Appliance
Circuit is coded.
2) Program the MPS-400 Notification Appliance Circuit for general alarm.
3) Terminate the power feed to the CMX module with a 2.2K ELR (P/N R-2.2K)
or make the power feed a return to the MPS-400 NAC terminals 3 and 4).
The wiring diagram shows an NFPA Style Z Notification Appliance Circuit
(all circuits are supervised and power-limited) using a CMX module. The
following table contains SLC wiring connections to the MPS-400 and CPU-400 as
shown in the wiring diagram.
Module
Connect...
MPS-400
24V (+) to TB* terminal 1
24V () to TB* terminal 2
* NAC TB7, TB8, TB9, or TB10

SLC () to TB5-3
Do not loop wiring under
any terminals. Break wire
run to maintain supervi-
