3.11.3 Interpreting CO Alarm/Supervisory Type Codes
The Type Code that displays in the CO Alarm message indicates the function of the point that initi-
ates the CO alarm. For example, a monitor module with a
CO MONITOR Type Code means that the
monitor module monitors a conventional CO detector. The table below lists the Type Codes that
can appear in an alarm message:

3.12.1 How the Control Panel Indicates an Active Trouble Monitor
Trouble Monitor Points are monitor modules programmed with the following Type Codes:
These types of monitor modules operate like monitored system functions that can produce trou-
bles—but with the following differences:
