The linkage and interlocking of fire fans are two different concepts.
The linkage of fire fans refers to the simultaneous operation of two or more fire fans to achieve better ventilation effects. For example, in the event of a fire, the fire fans of the main and auxiliary air intakes are activated simultaneously to enhance ventilation, exhaust more smoke and hot air, and help rescue personnel enter the fire more quickly.
The interlocking of fire fans refers to the automatic coordination and operation between fire fans and other fire equipment. For example, in the event of a fire, after the automatic sprinkler system is activated, the fire fan is automatically activated to control the fire and prevent its spread.
From these two concepts, the linkage of fire fans is an active operation mode, while the interlocking of fire fans is a passive cooperation mode. The different operating methods are all aimed at better ensuring personnel safety and preventing the spread of fires.
