ABSTRACT:
Horizontally hinged covers for use in ceiling/floors are provided which are highly fire resistant and which in the event of fire automatically close. The door preferably utilizes a multilayer construction comprising an intumescent lower (inner) layer, an intermediate structural layer and a top (outer) layer of a cementitious material. The horizontally hinged door utilizes an automatic closing system in the event of fire comprising a fusible link which activates a pressurized gas source to close the door and which pressurized gas source is automatically purged when the door is closed to prevent explosion of the pressurized gas source. The fusible link also actuates (opens) a hydraulic valve to allow the flow of hydraulic fluid from a pneumatic/hydraulic housing which is used with a movable rod to open and close the door.
