A system for controlling escape of pets during emergency, such as a fire, smoke, gas or odor emission, includes a passageway from the inside of the enclosure to the outside thereof. The passageway is normally closed by a door and an apparatus is provided for enabling opening of such door during emergency. A pre-recorded message urges the pet or pets to the open passageway only when the alarm device annunciating such emergency is intermittently disabled. A control apparatus is also provided for enabling passage of the pet or pets through the passageway and annunciates location of the pet or pets with respect to interior or exterior of the enclosure. A method is disclosed for remote operation of the controlled pet door to enhance safety of the pet owner attempting to enter residential dwelling.
