ABSTRACT:
A detector thermostat for fire detection systems is disclosed. Such detector thermostat includes a bimetal snap disc thermostat having a metallic disc cup which supports the snap disc. A heat collector is mounted on the disc cup in good heat transfer relationship therewith. The collector provides a flange formed with concentric circular convolutions and a circular array of projections cut from the material of the flange and extending substantially perpendicular to the flange. The projections are positioned around the disc cup and provide improved sensitivity to the flow of hot air and gases in a direction parallel to the plane of the flange.
