Note: There is one register for each fan. Each register is split into three segments, each having individual enable bits
for the four alarms that can be set. Bits 0 to 3 in the enable segment are also used to qualify the upper shutdown
and relay segments. If a bit is set in the upper segments an active alarm will only cause the relay or shutdown to
become active if the associated bit has been set in the enable segment.
