ABSTRACT:
A system for detecting and purging carbon monoxide from a confined space such as a parking garage, includes a plurality of carbon monoxide detectors (A) where each detector provides a detection signal (22) if a threshold level of carbon monoxide is detected. An activation circuit (B) receives the detection signal (22) from one or more of the detectors (A) and provides an exhaust fan activation signal (24). A motor starter (C) receives (1) the exhaust fan activation signal (24), and (2) input power (26) such as 110 VAC or 220 VAC, so that when the exhaust fan activation signal (24) is received from the activation circuit (B), the motor starter (C) provides a switched power output (28). An exhaust fan (D) receives the switched power output (28) from the motor starter (C) so that the exhaust fan (D) operates and thereby purges the carbon monoxide from the space. In a preferred embodiment, the activation circuit (B) includes (1) a relay (E) which is activated by any one of the detection signals (22), and provides a control signal output (30), and (2) a timer (F) which upon receipt of the control signal (30) provides the exhaust fan activation signal (24) for a predetermined period. Also in a preferred embodiment, the plurality of carbon monoxide detectors (A) are strategically placed in different locations within the space so as to ensure carbon monoxide detection throughout the space.
