Note! Please connect the fan connectors in the correct sequence: If two fans
are set on SW1, the correct method is to connect them into connectors
FAN1 and FAN2. If the two fans are connected to other fan connectors,
out of sequence, such as FAN1 and FAN3 or FAN2 and FAN3 or FAN3
and FAN4, then the alarm will not function correctly.
