3.6.3 How to Interpret Supervisory Type Codes
The Type Code that displays in the Supervisory message indicates the function of the point that
initiates the Supervisory. For example, a monitor module with a
TAMPER
Type Code means that the
monitor module connects to a tamper switch.
Type Codes that can appear in an Supervisory message:
