FC 69 - Test Alarm

The test alarm function code tests the alarm status of a designated input signal. It can test the alarm state on any block output that has a defined quality or alarm, including exception reports, station blocks, and device drivers.

 

There are two separate boolean outputs. Table 69-2 shows the different output descriptions for the types of blocks monitored. Note that for control stations, S2 selects the type of alarm monitored (absolute or deviation). Alarm status is zero equals no alarm, one equals alarm.
