ABSTRACT:
A ventilation system connected to a source of power for sensing a condition of air in an area monitored by said system and exchanging the air with fresh air upon sensing said condition. The ventilation system includes at least one strategically positioned sensor for sensing a characteristic in the air in the monitored area and comparing the characteristic to predetermined limit values and a fan for ventilating the monitored area. The fan is connected to the source of voltage by a connecting device upon a determination by the sensor that the characteristic of the sensed air exceeds the predetermined limit thereby causing the fan to remove the air within the monitored area and replace it with fresh air. The sensor senses any one of heat, smoke, carbon dioxide, carbon monoxide, hydrogen sulfide, hydrogen cyanide, any detectable gas, any emergency condition and any combination thereof. The fan is positioned within an air duct in the monitored area which leads to a position outside the monitored area. The system also includes a reset button connected to selectively disconnect the fan from the source of power.
