ST_SYSTEM OK2 is a second system OK status alarm available on some analyzers.

(Optional Alert)
07270D DCN7141
The T200H/M can be equipped with a set of 2 concentration alarms. Each alarm can be
independently enabled or disabled as well as programmed with its own, individual alarm
limit point (see Section 4.14 for details on programming the alarms).
The status of each alarm is available via a set of alarm relay outputs located on the lower
right hand corner of the analyzer's rear panel (see Figure 3-4). While there are four
relay outputs on the back of the analyzer, only two of the outputs correspond to the
instrument's two concentration alarms.
