The fast rate timer only becomes active when an alarm
condition is triggered by a rise or drop in the level of one of the
digital I/O channels. The default for the fast rate timer is three
seconds.

Note: When the fast rate timer is set to 0, a single report is sent when
an I/O alarm is triggered.

If the GPS timer is set to a value other than 0, it controls the
frequency of reports in the absence of any alarm or event
triggers. (However, if the GPS timer is set to a longer interval
than the low rate timer, the value for the low rate timer will
determine report frequency.)
