Switch group type 3 is for a fan that would require the capability of
sible to determine this information from either switch group type 1 or switch group type 2, switch group type 3 would only be necessary for
redundancy in verifying the state of the fan. For example, if switch group type 1 is used instead of switch group type 3, the
fan would be verified when the monitor module is activated and the
tivated. Utilizing switch group types 1 or 2 also saves the use of an additional monitor module. Switch group type 3 would use two monitor
modules to provide the same verification as types 1 or 2.
