OVERHEAD COILING AUTO-SET® MODEL FSFD

Fire and Smoke Rated Doors Without Egress

System Description: The McKeon Auto-Set® fire & smoke rated doors are recommended in situations where fire protection is required but emergency egress is not an issue. The Auto-Set® fire door is a vertically acting fire door which is UL classified for up to four hours in both masonry and dry wall applications. In the event of a fire alarm, power failure, the breakage of a fusible link, or activation of the True Test â„¢ Panel, the hold open brake is released and the door self-closes without the aid of electricity or battery back-up. The rate of descent is controlled by a centrifugal governor which is engaged when the closing speed of the door reaches six inches per second. Any Auto-Set® fire door may be equipped with the optional ten second time delay. The purpose of the ten second time delay is to prevent nuisance closure due to momentary power failure. Once the door is closed and the power is energized, or the alarm signal is cleared, the door and the time delay mechanism automatically reset without the need for tools or a technician.

System Advantages:

Unlike conventional fire door design any number of Auto-Set® fire doors, in a given area, or throughout a building, can be connected in a series, such that the activation of a single fusible link on any door will activate every door in a designated area or in an entire building. As an added life safety feature, the safety edge is still active on the Auto-Set® fire door after the activation of the fusible link. The True Test ™ panel triggers an actual drop test in accordance with NFPA 80 by releasing the constant hold open brake and allowing the door to close under gravitational force. When the test panel is set back to standard mode, the door automatically resets. The True Test ™ panel is designed to drop test and reset multiple doors simultaneously.

 

Design Alternatives: Conventional fire doors are difficult to test and are often improperly reset. Malfunctions typically occur when the spring tension is misapplied during installation or conventional resetting procedures. Auto-Set® fire doors are always biased to the closed position. The spring tension is not adjusted and the door is automatically tested and reset.

 

Applications: Auto-Set® fire doors are ideal for use in schools, hospitals, convention centers, casinos, museums, airports, hotels and industrial facilities. They are frequently used in area separations, occupancy separations and corridor separations.
