Abstract: The current invention is an automatic AC power interruption system built into a portable apparatus or integrated into electrical systems and appliance control circuitry. Power is interrupted in potentially hazardous conditions, for example, when a T3 smoke detector alarm signal is detected. Alternatively, a portable device may be plugged into a power outlet having a GFCI breaker and, when a hazard alarm condition is detected, trip off power to the outlet. Signal-activated circuit interrupters (SACIs) may be integrated into appliance control circuitry and interrupt power to a problematic device when a hazard alarm condition is detected. In addition to fire prevention, other hazard alarm conditions may include alarms indicating toxic fumes, motor overload, natural gas, radon, or carbon monoxide. Interconnected networks of signal-activated circuit interrupters are also disclosed.

Abstract: The current invention is an automatic AC power interruption system built into a portable power strip or a portable casing or integrated into an appliances control circuitry. The invention monitors the environment for hazard alarms, for example, a T3 signal smoke detector alarm, and responds by tripping open the power supply circuit to the power strip's receptacles and thus interrupts AC power to the protected appliances the user has chosen to plug into them. One alternate form of the invention uses a portable casing that can be plugged into a power receptacle and, when a hazard alarm is detected, trip off the nearest GFCI. Other alternate forms of the invention are integrated within an individual appliance's control circuitry and may interrupt power using a built-in switch or by tripping off the nearest GFCI device.
