operation is performed.
However, updates to these NCIs will have no effect if they contain an illegal value. Additionally, the
actual alarm thresholds (which are indicated by nvoAlmThresh1 and nvoAlmThresh2) may differ if
changed using the front-panel user interface.
So setting the sensor alarm thresholds is intuitive using either these two NCIs or the front panel. But
mixing the two strategies can be cumbersome. The units are the same as nvoAlarmThresh1, see
above.
A.4.5 Implementation of nviRequest
The object request variable can convey a variety of commands to LonWorks nodes. Not all of these
messages are applicable to the LIFELINE II.
The following table lists which of these requests are implemented. Blank entries correspond to
unimplemented requests.
