  • Patent number: 4161804
    Abstract: A door control comprising a heat-actuated door latch and a combination door-closing-arm holder and release. An optional smoke detector is located within a holder-release housing. During normal conditions, the door-closing arm is set at a hold-open angle free of the door to permit an easy door swing. In response to an emergency or smoke condition, the closing arm is released to pick up and close the door. In the event of excessive heat, the door is latched in response to the separation of fusible link segments. Heat from the side of the door opposite the latch housing is conducted through the door by a heat conducting rod.
