Abstract
Systems and methods for controlling a system of fans in a facility from a central system controller are disclosed herein. In one embodiment, the system of fans can be configured to shut down automatically during an emergency condition or event. For example, a fan system controller can be connected to the system of fans and provide a signal to each of the fans. While each of the fans receives the signal, power is connected to a motor on each of the fans. Upon detection of an emergency condition, the fan system controller disconnects the signal to the fans, thereby automatically simultaneously shutting down the entire system of fans.
