4. Appendix B N30 Supervisory Controller User s Manual B 1 Building an Alarm Application Introduction There are two methods of alarm routing for the N30 Supervisory Controller the Notification Class alarm routing feature and the Message Router feature This appendix describes aspects of these features including alarm routing recommendations how Status Notification Reports SNRs are routed how message filtering is configured and how the Notification Class and Message Router objects interact with other objects For further information about the objects described in this appendix see the Working with Notification Class Objects LIT 6892290 and Working with Event Enrollment Objects LIT 1201218 chapters in the N30 Supervisory Controller User s Manual and the relevant object chapters in the Object Dictionary For information about generating N30 databases using Project Builder refer to the N30 Supervisory Controller Quick Start Technical Bulletin LIT 6891200 May 1 2002 Johnson Controls Inc www johnsoncontrols com Code No LIT 6892320 Software Release 5 1 B 2 Appendix B Building an Alarm Application Key Concepts Alarm Routing Recommendations Notification Class We recommend using Event Enrollment alarming or Intrinsic alarming with this type of alarm routing If routing to third party non Metasys system BACnet devices is required then Notification Class objects must be used for alarm routing Message
