TESTING — AUTOMATICALLY RESETS . . . |
The Auto-Set® Retrofit Option eliminates testing
difficulties and improper resetting by eliminating all the
components that typically fail on fire doors and incorporating them
into the Fire Door Operator. The Fire Door Operator is highly
durable, automatically resets itself, and has been tested by Factory
Mutual for 50,000 operational cycles and 525 consecutive drop tests.
Conventional fire doors are only tested for 7,500 operational cycles
and 25 drop tests.

FMRC APPROVES ROLLING STEEL
FIRE DOOR
FEATURING SIMPLE INSTALLATION, TESTING AND RESETTING . . .
Rolling steel fire doors serve an important purpose: they
protect openings in fire walls built to separate sections of
a building and prevent the passage of flame and hot gases.
However, results of a study show that nearly 20 percent of
installed rolling steel fire doors could fail to operate in
an emergency. The main culprits: improper installation,
misapplied spring tension and lack of proper door
maintenance.
A new type of rolling steel fire door recently receiving
approval from the Factory Mutual Research Corporation
features a design that will improve the reliability of these
important loss control devices. The door, Model FSFD
manufactured by McKeon Rolling Steel Door Company, Inc., of
Brooklyn, N.Y., features a novel innovation to the automatic
closing device.
What makes McKeon door different is that it utilizes an
electrical, constantly engaged, hold-open brake as the
method of automatic closure control, rather than a
convention spring tensioning device. As long as electricity
is supplied to the unit, the brake, located in the gearbox
assembly, remains set and prevents the curtain from closing. |

Upon a loss or interruption of power or the activation
of a fusible link, the brake retracts, freeing the gear
train and allowing the curtain to close. The door’s rate of
descent is controlled by a quiet and efficient centrifugal
governor unlike that found on most fire doors.
“The use of an electrically operated, automatic device,
rather than the typical counterbalanced spring tension
device, results in a rolling steel fire door that is simple
to install, maintain, test and reset.” said John Rennie,
Vice President of FMRC’s Approvals Division. “Approval and
use of this door/assembly is eventually expected to reduce
significantly the percentage of rolling steel fire door trip
test failures.”
The assembly is fire rated up to and including four hours
for wall openings up to 144 sq. ft. Oversized doors are also
available.
FMRC’s Approvals Division is a leading resource for
manufacturers seeking third-party certification of their
products in response to the demands of customers and
regulatory agencies. FMRC’s Approval of a product to
specific standards provides the end user and manufacturer
reassurance that the product’s performance claims have been
verified. |
