Table 19 – ST900 Family Timings Summary

Active DFM times are specified in minutes and inactive DFM times are specified in hours. The
value of 0 gives a short DFM timeout period of less than a minute for test purposes. The value of
255 disables detector fault monitoring of that state for the associated group during the associated
timeset.
