Claim:
1. A system for automatically shutting off appliances consisting of: a sensor for sensing a predetermined environmental condition; a transmitter in communication with said sensor, said transmitter sending a signal in response to said sensor sensing said predetermined environmental condition; a receiver, located remotely from said transmitter, capable of detecting said signal and activating, in response to receipt of said signal; a timer for counting down a pre-set time interval, said timer consisting of an electronic semiconductor timing circuit and an electronic switching device; a timer alarm operatively coupled to said timer for indicating when said timer has begun counting down said pre-set time interval; a deactivating device connected in series with a power supply of an appliance for deactivating said appliance by decoupling said appliance from said power supply in response to expiration of said pre-set time interval; an override mechanism for stopping said timer counting down said pre-set time interval; a second timer to begin counting down a second pre-set time interval when said override mechanism is triggered, said override mechanism to return to a non-override position upon expiration of said second pre-set time interval, thereby causing said first timer to again countdown said pre-set time interval.
