ABSTRACT:
A vapor sensitive resistor, or switch, is connected in a bridge network having the input connected to the battery of a marine engine. A window signal comparator includes a high limit operational amplifier and a low limit operational amplifier, each have a first input connected to the opposite sides of a reference resistor in the bridge network to establish relatively high and low reference voltages and second inputs connected in common to the sensing resistor. The amplifiers include a positive feedback and two outputs are connected to an "OR" logic gate which is connected to drive a two-stage transistor amplifier wholly on or off. An alarm device is connected in series with the amplifier to the battery. A test switch varies the circuit connection of the vapor sensitive resistor to simulate a high or low limit condition and thereby test circuit operation.
