Johnson Controls, Inc. SLC Wiring Manual — P/N 51870:G 04/23/2009 57
Supervising 24 VDC Power Power Considerations
Style Z NAC Power Wiring (Alternate)
Program the NAC from the control panel for general alarm. (Refer to the programming manual or
programming section of the FACP documentation for instructions.) Note that if the NAC is a coded
output, the M300CJ output will be coded as well.
Refer to the Device Compatibility Document for compatible notification appliances.
• The circuit is supervised and power-limited.
• In this circuit, an external ELR is not required at end of the NAC circuit.
• Refer to the respective control panel installation manual for NAC terminal block connection
information.
• Remove internal resistor on each M300CJ (see instructions in Figure 7.2 on page 42).
Connect the NAC power as follows:
