Abstract

A carbon monoxide detector and method for installing a carbon monoxide detector. The carbon monoxide detector is capable of being hardwired into an installed wall electrical outlet box without reduction of the number of available electrical receptacles.

Claims

1. A tamper proof carbon monoxide detector in combination with a wall electrical outlet box, the carbon monoxide detector comprising:

an integrated unit configured to fit within said wall electrical outlet box, said integrated unit comprises substantially completely therein a controller, a notification device, a carbon monoxide sensor, and two or more electrical terminals, said electrical terminals used to electrically connect said carbon monoxide detector to electrical wires emanating from said electrical outlet box;

said controller receives a first signal from said carbon monoxide sensor and generates a second signal, said first signal being indicative of carbon monoxide presence; and

said notification device receives said second signal and produces an output based thereon.

2. The carbon monoxide detector combination of claim 1, wherein said notification device is a visual notification device.

3. The carbon monoxide detector combination of claim 1, wherein said notification device is an audible notification device.

4. The carbon monoxide detector combination of claim 1, in which said integrated unit further comprises:

a sensing device, said sensing device being coupled to said controller and being responsive to a third signal different from said first signal and said second signal, said third signal being emitted by another carbon monoxide detector.

5. The carbon monoxide detector combination of claim 1, wherein said sensing device is a wireless sensing device.

6. The carbon monoxide detector combination of claim 1, the carbon monoxide detector further comprising:

a wireless transmitter.

7. The carbon monoxide detector combination of claim 1,the carbon monoxide detector further comprising:

at least one electrical receptacle.

8. The carbon monoxide detector of claim 7, wherein said at least one electrical receptacle is integral with said carbon monoxide detector.

9. The carbon monoxide detector combination of claim 1, wherein said wall electrical outlet box is located within a wall.

10. The carbon monoxide detector combination of claim 9, wherein the carbon monoxide detector, when mounted within said wall electrical outlet box, is substantially flush with said wall.

11. The carbon monoxide detector combination of claim 10, wherein said two or more electrical terminals are two or more electrical wires.

12. The carbon monoxide detector combination of claim 1, in which said integrated unit further comprises:

a battery.

13. A method for retrofitting an installed wall electrical outlet box with a carbon monoxide detector, the method comprising:

removing a source of electrical power from the wall electrical outlet box;

removing a cover plate from the installed wall electrical outlet box, the installed wall electrical outlet box containing two or more electrical wires;

providing a carbon monoxide detector comprising;

an integrated unit configured to fit within said wall electrical outlet box, said integrated unit comprises substantially completely therein a controller, a notification device, a carbon monoxide sensor, and two or more electrical terminals, said electrical terminals used to electrically connect said carbon monoxide detector to one or more electrical wires emanating from said electrical outlet box;

said controller receives a first signal from said carbon monoxide sensor and generates a second signal, said first signal being indicative of carbon monoxide presence; and

said notification device receives said second signal and produces an output based thereon;

removing an at least one receptacle from the installed wall electrical outlet box;

disconnecting the at least one receptacle from at least two electrical wire of the installed wall electrical outlet box;

installing said carbon monoxide detector in the installed wall electrical outlet box;

coupling electrical terminals of the carbon monoxide detector to two or more electrical wires of the installed wall electrical outlet box;

coupling at least one electrical receptacle of the carbon monoxide detector to the at least two electrical wires of the installed wall electrical outlet box; and

reinstating the source of electrical power to the wall electrical outlet box.
