Abstract
One embodiment of the present invention discloses an odor-generating alarm apparatus that can ensure the reliability of a releasing operation and the odor dispersibility. In an odor-generating alarm apparatus, when abnormality information indicating occurrence of an abnormal state is supplied from a sensor for occurrence of an abnormal state, an initiator is operated by a circuit portion, and the initiator displaces a piston of a driving portion and displaces a spray can with respect to a casing and switches the spray can to a releasing state, thus releasing an odorous liquid filling the spray can in the form of fine particles.
