1. A combination smoke, carbon monoxide and hydrocarbon detector comprising, in combination:
- a housing with a generally rectangular configuration having a front face, a rear face, a top face, a bottom face, and a pair of arcuate side faces defining an interior space, the bottom face having a plurality of apertures formed therein, the front face having three circular linearly aligned cut outs formed therein, the housing further including a pair of sound vents for allowing the uninhibited transmission of sound from the interior space of the housing;
smoke detection means situated within the interior space of the housing, the smoke detection means adapted to transmit a smoke signal upon the detection of smoke through the apertures of the housing;
carbon monoxide detection means situated within the interior space of the housing, the carbon monoxide detection means adapted to transmit a carbon monoxide signal upon the detection of carbon monoxide through the apertures of the housing;
hydrocarbon detection means situated within the interior space of the housing, the hydrocarbon detection means adapted to transmit a hydrocarbon signal upon the detection of hydrocarbon through the apertures of the housing;
a smoke indication lamp of a first color positioned in one of the cut outs of the housing and connected to the smoke detection means, the smoke indication lamp adapted to illuminate upon the receipt of the smoke signal thereby giving a visual alert of the presence of smoke in a local area;
a carbon monoxide indication lamp of a second color positioned in one of the cut outs of the housing and connected to the carbon monoxide detection means, the carbon monoxide indication lamp adapted to illuminate upon the receipt of the carbon monoxide signal thereby giving a visual alert of the presence of carbon monoxide in the local area;
a hydrocarbon indication lamp of a third color positioned in one of the cut outs of the housing and connected to the hydrocarbon detection means, the hydrocarbon indication lamp adapted to illuminate upon the receipt of the hydrocarbon signal thereby giving a visual alert of the presence of hydrocarbon in the local area;
audio alarm means situated within the housing and connected to the each detection means, the audio alarm means adapted to emit a high intensity audio alarm upon the receipt of an activation signal, whereby the frequency of the audio alarm is dependent on a frequency of the activation signal;
tone control means situated within the housing and connected to the audio alarm means for deploying a first activation signal having a first unique frequency only upon the receipt of the smoke signal, a second activation signal having a second unique frequency upon the receipt of the carbon monoxide signal, and a third activation signal having a third unique frequency only upon the receipt of the hydrocarbon signal;
state control means situated within the housing and connected between the smoke, carbon monoxide, and hydrocarbon detector and the tone control means, the state control means adapted to continuously transmit the smoke signal to the tone control means upon the receipt of the smoke signal and coincident lack of receipt of the carbon monoxide signal and hydrocarbon signal, the state control means adapted to continuously transmit the carbon monoxide signal to the tone control means upon the receipt of the carbon monoxide signal and coincident lack of receipt of the smoke signal and hydrocarbon signal, the state control means adapted to continuously transmit the hydrocarbon signal to the tone control means upon the receipt of the hydrocarbon signal and coincident lack of receipt of the smoke signal and carbon monoxide signal, the state control means further adapted to alternatively transmit the signals received from the detection means to the tone control means upon the coincident receipt of at least two signals from the detection means thereby effecting an alternating multi-tone audio alarm with each tone having a predetermined frequency of oscillation;
a plurality of test buttons including a smoke test button situated below the corresponding indication lamp and adapted to effect the transmission of the smoke signal from the smoke detection means upon the depression thereof, a carbon monoxide test button situated below the corresponding indication lamp and adapted to effect the transmission of the carbon monoxide signal from the carbon monoxide detection means upon the depression thereof, and a hydro carbon test button situated below the corresponding indication lamp and adapted to effect the transmission of the hydrocarbon signal from the hydrocarbon detection means upon the depression thereof; and
battery power monitoring means connected to a battery, the battery monitoring means adapted to transmit a battery low signal upon power delivered by the battery falling below a predetermined level.

Abstract
A combination smoke, carbon monoxide and hydrocarbon detector including a smoke detection mechanism adapted to transmit a smoke signal upon the detection of smoke, a carbon monoxide detection mechanism adapted to transmit a carbon monoxide signal upon the detection of carbon monoxide, and a hydrocarbon detection mechanism adapted to transmit a hydrocarbon signal upon the detection of hydrocarbon. Next provided is an audio alarm mechanism situated within the housing and connected to the each detection mechanism. The audio alarm mechanism is adapted to emit a high intensity audio alarm upon the receipt of a signal, whereby the type of audio alarm is unique to the signal received. Further provided is control circuitry having a first mode of operation when only one signal is received from the detection mechanism whereby the control circuitry continuously transmits the one signal to the audio alarm means upon the receipt thereof. The control circuitry further having a second mode of operation when more than one signal is received from the detection mechanism whereby the control circuitry alternately transmits each of the signals to the audio alarm mechanism.
