Abstract
Official abstract text for this publication.
A smoke ventilation system comprising a system controller connected to window actuators of different building areas, and control points associated with the window actuators of different building areas, the system controller comprises a power supply module powering the window actuators and the control points, wherein the control points are connected to the system controller by a common serial bus comprising power supply and communication lines for communicating serial control signals to activate the associated window actuators of a building area.
First claim
Opening claim text (preview).
The invention claimed is: 1. A smoke ventilation system comprising a system controller connected to window actuators of different building areas, and control points associated with the window actuators of different building areas, the system controller comprises a power supply module powering the window actuators and the control points wherein the control points are connected to the system controller by a common serial bus comprising power supply and communication lines for communicating serial control signals to activate the associated window actuators of a building area. 2. The smoke ventilation system according to claim 1 , wherein at least one of the window actuators is connected to the system controller by a power supply and communication line. 3. The smoke ventilation system according to claim 1 , wherein at least one of the window actuators is connected to the system controller by a 2-wire power supply line. 4. The smoke ventilation system according to claim 1 , wherein the window actuators of a building area communicate status signals to the associated control points via the system controller. 5. The smoke ventilation system according to claim 1 , wherein a control point comprises a manual and/or automatic smoke detector. 6. The smoke ventilation system according to claim 1 , wherein a control point comprises a window actuator for activating the window operators in order to provide comfort ventilation. 7. The smoke ventilation system according to claim 1 , wherein the system controller comprises a programming and communication module powered by the power supply module, the programming and communication module handle communication between the control points and the associated window actuators, and the association of control points to different window actuators. 8. The smoke ventilation system according to claim 1 , wherein the system controller comprises a window actuator module wherein the window actuators are connected to the system controller. 9. The smoke ventilation system according to claim 1 , wherein the system controller comprises a connection module wherein to the control points are connected to the system controller. 10. The smoke ventilation system according to claim 1 , wherein a plurality of system controllers are connected by a serial communication bus. 11. The smoke ventilation system according to claim 10 , wherein more series of system controllers are connected by a serial communication bus in parallel.
