Abstract
A fire/smoke damper control system is provided for use in monitoring and controlling operation of one or more fire/smoke dampers in a building. The system includes a local damper controller associated with each fire/smoke damper for controlling the opening and closing of each fire/smoke damper, a remote router for controlling the operation of one or more local damper controllers, and circuit communication between the remote router and each local damper controller. The control system allows for localized power supply for damper actuation, eliminating the pulling of wire from each damper back to a central power panel.
