Abstract
A power cut-off system for cutting a 220V power supply, or any other voltage value, of an electrical device, such as an oven for example, while maintaining a 110V power supply, or any other voltage value, to the electrical device, the system comprising a control-board unit connected to the 220V power supply of the electrical device and providing 110V and 220V respectively to the electrical device, the control-board unit including a transponder for sending and receiving wireless signals. The system also includes a smoke detector unit for detecting smoke and sending a wireless signal to the transponder of the control-board unit to cut-off the 220V power supply of the electrical device while maintaining the 110V power supply to the electrical device.
Claims20
A power cut-off system for cutting a power supply of a given voltage from an electrical device present in a first environment, the system comprising:
- a control-board unit operatively connected to the power supply of the electrical device, the control-board unit including a transponder for sending and receiving wireless signals;
- and
- a smoke detector operatively connected to the control-board unit and configured for detecting levels of smoke in a second environment and sending at least one wireless signal to the control-board unit in order to cut-off the power supply of the electrical device upon attainment of a given threshold of smoke level in the second environment.
A method of cutting a power supply of a given voltage from an electrical device present in a first environment, the method comprising the steps of:
- a) providing a control-board unit operatively connected to the power supply of the electrical device, the control-board unit including a transponder for sending and receiving wireless signals;
- and
- b) providing a smoke detector operatively connected to the control-board unit and configured for detecting levels of smoke in a second environment and sending at least one wireless signal to the control-board unit in order to cut-off the power supply of the electrical device upon attainment of a given threshold of smoke level in the second environment.
