Fire sentry

摘要

System, method, and apparatus for automatically disabling an appliance to prevent accidental fires. A shut-off system is coupled to a smoke detector. When the smoke detector alarm is activated a signal is sent to the shut off system coupled to a cooking appliance. The shut off system includes a timer and an override mechanism. If the override mechanism is triggered prior to the timer expiring, then the shut off system does not activate. If the override mechanism is not triggered prior to the timer expiring then the shut off system activates and decouples the appliance from its power supply.

主权项

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.
