Abstract
An automatic stovetop fire suppressor with suppressor activation triggering an audible alert of a fire condition and method are provided herein. A plastic bottom lid is secured to a bottom of a can, forming a closed container. A fire suppressing agent and a sound board are housed within the closed container. As the fire suppressor actuator is triggered, the bottom lid lowers releasing the fire suppressing agent and tripping a sound board alert switch. A microcontroller generates a desired fire condition signal which is played across a low voltage magnetic transducer. The suppressor is user friendly, provides an automated release of fire suppressing agent in the presence of a stovetop fire, and emits a continuing audible alert signal until a user disables the same. The fire suppressing agent and battery powered sound board are stored in the closed from manufactured end to activation of the suppressor in a fire condition.
