A fire suppression apparatus for suppressing a fire in a room includes a housing which attaches to a surface and houses a container filled with a pressurized fire suppressant. A fire sensor monitors a room for one of a presence of a flame or a temperature above a threshold temperature. When either the presence of a flame is or the temperature above the threshold temperature is detected, a timer is started by a control circuit, which then releases the fire suppressant after the timer reaches a predetermined time period. A reset input is provided for terminating the timer and preventing the release of the fire suppressant.
