| TESTING
DIFFICULTY / IMPROPER RESET |
 |
 |
| Testing difficulties often
stem from malfunctions with sash chains and fusible links.
Additional malfunctions occur when spring tension is misapplied
during installation or conventional resetting procedures. |
THE SOLUTION? 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. Sash chains are
still possible problems with the Auto-Set® System if they are used.
However, the Auto-Set™ System allows you to connect multiple doors
with fusible links without the need for sash chains. In addition,
since the magnetic release is an integral part of the operator, the
need to connect a remote magnetic release to the fire door with a
sash chain is eliminated. Therefore during alarm activations, sash
chains are never used.

| INADEQUATE
MAINTENANCE |
 |
 |
| Often, as a
result of improper maintenance, fusible links and gears malfunction
due to rusting metal parts or paint build-up on gears and sash
chains. Under no circumstances should fusible links be painted.
Paint thermally insulates the lead in the fusible link and may
prevent the link from functioning correctly. |
THE AUTO-SET® SOLUTION: The
Auto-Set® System is a low maintenance product. The number of working
parts has been radically reduced and incorporated into the Auto-Set®
Operator. The mechanical parts which are prone to maintenance
problems have been eliminated.

DAMAGE |
 |
Damage to fire doors usually
results from forklift impact or the improper stacking of heavy
warehouse merchandise against the door.
THE AUTO-SET® SOLUTION: Fire doors should be designed to
overlap the opening and should be designed in a manner which allows
for easy testing and resetting to periodically check for damage,
which may not be visible to the eye. The Auto-Set® System is
designed for daily testing and resetting. A typical Auto-Set® door
takes less than a minute to test and reset. |
