Figure 60 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 and normally open contact
alarm initiating device. Refer to Figure 62 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 more information, refer to the 500 Series Intelligent Modules
Technical Bulletin (LIT-408100).
