„ CRT O - Critical Condition Operations
The Critical Condition Operations menu varies based upon the system's current condition. Any one of three
conditions may exist.
An active critical condition exist: This state is entered when the number of critical input channels that are
simultaneously in the active alarm state meets or exceeds the critical condition threshold.
An inactive critical condition exists: This state is entered from the active critical condition state after the
number of critical input channels that are currently in the active alarm state does not meet or exceed the critical
condition threshold.
No critical condition exists: This state is entered only after a user manually resets the critical condition logic
using the CRT O command.
