Fire control systems

摘要

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.

主权项

1. A fan system comprising:
a first facility fan; at least a second facility fan; a fan system controller configured to receive a first signal from an alarm system, wherein the alarm system is configured to transmit the first signal during a non-emergency condition and to cease transmission of the first signal upon detection of an emergency condition; a first link connecting the fan system controller to the first facility fan, wherein the fan system controller is configured to transmit a second signal to the first facility fan via the first link when receiving the first signal from the alarm system, and wherein the fan system controller is further configured to cease transmission of the second signal to the first facility fan in the absence of receiving the first signal from the alarm system; and a second link connecting the first facility fan to the second facility fan,
wherein the second link is configured to transmit the second signal from the first facility fan to the second facility fan when the first facility fan is receiving the second signal from the fan system controller;wherein the first facility fan and the second facility fan are configured to operate when receiving the second signal, and wherein the first facility fan and the second facility fan are further configured to shut down in the absence of receiving the second signal.
