3.5.10

Does the operator have access to alarm inputs?

The operator should have the capability of viewing inputs to the alarm processing system (sensor data). Operators may need to view sensor data that results from alarm system processing under certain circumstances, such as if the pattern of alarm messages appears to be contradicting, or if operators suspect that there is a problem with the processing system. The alarm system should provide functions that enable users to evaluate the meaning or validity of the alarm messages.
