Note! 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, instead of FAN1 and FAN2, then the alarm will not function cor-
rectly.
