Switch group type 6 is for a fan that would require the capability of
sible to determine this information from either switch group type 4 or switch group type 5, switch group type 6 would only be necessary for
redundancy in verifying the state of the fan. For example, if switch group type 4 is used instead of switch group type 6, the
fan would be verified when the monitor module is activated and the
tivated. Utilizing switch group types 4 or 5 also saves the use of an additional monitor module. Switch group type 6 would use two monitor
modules to provide the same verification as types 4 or 5.
