| IMPROPER
INSTALLATION |
 |
Fire door malfunctions often
originate during installation, as a result of inexperienced
installers and poorly prepared installation instructions.
THE AUTO-SET® SOLUTION: Fire doors should be designed in a
manner allowing for easy testing and resetting verifying that the
door was installed correctly and will function properly when the
need arises. The Auto-Set ® System is designed for daily testing and
resetting. |
| MANUFACTURING
QUALITY (DEFECTIVE PARTS) |
 |
 |
Manufacturing
defects in the external gears and mechanical governors which are
inherent with the conventional fire door design can result in
unpredictable and hazardous conditions.
 |
THE AUTO-SET® SOLUTION: The
Auto-Set® System has eliminated all the external parts which are
prone to malfunction on conventional fire doors. The Auto-Set®
System has been tested by Factory Mutual Research Corporation, for
50,000 operational cycles and 525 drop tests. Conventional fire
doors are tested for 7,500 operational cycles and 25 drop tests.

OCCUPANCY RELATED — (BLOCKED and
WEDGED DOORS) |
 |
Fire doors are blocked and
wedged by occupants of the building because they have been trip
tested and not reset.
The occupant has wedged them in order to provide access through the
opening.
Fire doors are blocked by material or fork trucks which are placed
in the openings. |
THE AUTO-SET® SOLUTION: The
Auto-Set® System automatically resets itself. Therefore, the
possibility of an Auto-Set® door being tripped and not reset has
been eliminated. If blocked doors has been a problem, McKeon Door
will provide a detection system which will set off an audible alarm
if the opening is blocked for a period of more than two minutes. In
addition to this detection system, we recommend that the opening be
clearly marked and signs posted stating that material cannot be
placed under the fire door. |
