1. An automatic gas detection system for the passenger compartment of a vehicle provided with power windows which are connected to a vehicle battery by an ignition switch;
- wherein, the system consists of;
a gas detection unit including a carbon monoxide sensor mounted within the passenger compartment;
an alarm unit including a steering wheel mounted multi-function alarm member;
a power window unit including a reversible power window motor having a power window relay element; and
,a control unit including a microprocessor control member operatively connected to the vehicle battery via the ignition switch and operatively associated with the alarm unit, the gas detection unit, and the power window unit for activating the alarm unit and the power window unit in response to the output of the gas detection unit;
wherein, the multi-function alarm member is provided with visual, audible and tactile features; and
the microprocessor control member will activate the power window relay element to drive the reversible power window motor in one direction to lower the power windows from the closed position in response to the carbon monoxide sensor detecting high concentrations of carbon monoxide within the vehicle passenger compartment;
wherein, the maximum distance that the power windows are lowered is four inches.
