Hardware Installation—Installing the IFC-1010/2020
87
Figure 61 illustrates an M500MJ monitoring normally open contact fire
alarm initiating devices that do not require power and an M502MJ
monitoring powered two wire smoke detectors. Refer to Figure 63 for
circuits using four wire detectors.
Notes: For additional ratings, refer to Circuit/Device Ratings and
Connections Technical Bulletin (LIT-448160).
For connection of the initiating devices, refer to the manufacturer’s
installation instructions packaged with each device.
For M502MJ, mount the appropriate EOLR across Terminals 8 and 9.
For more information, refer to 500 Series Intelligent Modules
Technical Bulletin (LIT-408100).
