DASMA Technical Data Sheet 271 v2.jpg

 

General

This Technical Data Sheet provides facility managers with guidelines for evaluation of rolling fire doors designed and tested to provide the automatic closing fire protection indicated on the fire door label. The automatic closing of the door must be tested at the time the door is installed, and the door shall be inspected and tested not less than annually as required by NFPA 80. This requirement applies to all fire doors – even those that are not used and remain in the closed position. The doors must be checked regularly for conditions that may affect the operation of the door. DASMA recommends that the following procedures be observed:

Inspection:

  • Inspect fire doors for damage to guides, curtain and endlocks, bottom bar, hood and operating mechanism.
  • Refer to DASMA Technical Data Sheet #270 (“Recommended Rolling Door Maintenance Practice”)
  • Refer to NFPA 80 (Standard for Fire Doors and Other Opening Protectives)
  • Ensure that the door’s operating mechanisms, fuse links and release chain/cable are not painted, coated with dust or grease, and/or covered with debris.
  • Open and close the door to inspect for any indications of damaged parts.
  • Remove flammable substances on each side of the firewall opening near the fire door.

 

Droptest:

  • Have a trained door systems technician perform an inspection and drop test of all fire door automatic closing features.
  • Establish a contract with the door service provider regarding the cost of the inspection and drop test. Fire door deficiencies identified during the pre-drop test inspection should be corrected before the drop test. The drop test contract should acknowledge the fact that components may fail during the drop test that are not the fault of the service provider and are not included in the cost of the drop test.
  • Document the drop test with the attached DASMA Drop Test Form.
  • When subjected to drop testing, the door must close completely and rest on the sill. NFPA 80 states that the average closing speed must not exceed 24 inches per second and must be at least 6 inches per second.
  • The door must be drop tested twice – once to verify proper operation and full closure, and a second time to verify that the automatic closing device was properly reset.

 

DASMA ROLLING STEEL FIRE DOOR DROP TEST FORM

General

NFPA 80 and Model Codes require the inspection and testing of fire doors to demonstrate proper operation, full closure, and proper reset. Perform the visual inspection before the operational check, or before the drop tests of the fire door, in order to reduce the risk of failure during the drop tests. Use the form below to record the Visual, Operational, and Drop Test results. Check Pass or Fail in the boxes. See the Guidelines for additional information.

The drop tests, reset, repairs and/or maintenance should be performed by a trained door system technician with complete knowledge of this type of fire door and the manufacturer's instructions. Repair parts must be obtained from the original door manufacturer. After repairs are completed, the door must be tested to assure proper door operation and automatic closing capability. The fire door must be in the fully open position before the drop test. Reset the door following the drop test and test again.

Commercial Doors: Sectional Doors VS Rolling Doors

Posted by Elizabeth Aceves on Fri, Jul 19, 2013 @ 06:33 PM

Sectional Doors VS Rolling Doors

dilema

There are so many options when it comes to commercial doors. Depending on the area you are securing, separating or monitoring access to, you may want a particular type. However, when it comes down to it, we sell two main types here at The Overhead Door Company of The Meadowlands and New York City, sectional doors and rolling doors. Within those two types, you will find several different subtypes.

Learn more about commercial sectional doors and commercial rolling doors, as well as the subtypes we offer, so you have a better idea what type of door you need for your particular commercial need.

Commercial Sectional Doors

Sectional doors are created with convenience in mind. These doors work with a controller that can make opening and closing them a breeze. With options like Thermacore, sectional doors are a great choice for spaces that need temperature control. Today’s sectional doors are well constructed for reliable use and minimal maintenance required. Some of the more popular types of commercial sectional doors available at The Overhead Door Company include the following:

  • Advanced Sectional Doors – For advanced performance, many industrial and commercial buildings need a simple, well-rounded sectional door. The advanced sectional doors at The Overhead Door Company offer climate control, ease-of-use and durability. While useful in a number of situations, these are a great choice for commercial garages.
  • Thermacore Doors – For industries that need the upmost in thermal efficiency, the Thermacore door is a perfect solution. These thick doors keep temperatures at a steady level, saving you money over time.
  • Sectional Steel Doors – For one of the best combinations of heavy-duty workmanship and convenience, sectional steel doors are a great solution. You often find these doors on fire stations, commercial garages and retail establishments.
  • Aluminum Doors – Aluminum doors offer a sense of architectural style while still providing protection and the ability to easily open and close your commercial door. This is a good choice for buildings where it is important to make a good impression.
Sectional Doors

Commercial Rolling Doors

Rolling doors, also known as rolling shutters, are created to protect the contents within an establishment. These doors are easy-to-secure and allow you to protect the interior of your commercial structure. Certain styles are used within buildings, to separate sections of a building into individual areas.

  • Advanced Service Doors – When service AND security are important, one of these advanced service doors is the perfect solution. They offer the fast open and close cycles that are in line with a sectional door; however, you get the increased security of a rolling door.
  • Rolling Steel Doors – A standard rolling steel door is the go-to option for loading docks at warehouses, factories and storage facilities. It offers great security at a great price.
  • Fire Rated Doors – In certain buildings, such as schools and hospitals, a fire rated door is a necessity—both for safety and to meet the regulations of the city or county. These fire rated doors offer many of the same options of our standard service doors with the added fire rating.
  • Counter Doors (Counter Shutters) - When you have a service counter, such as at a snack bar, service counter or ticketing area, you need a way to protect the space when the counter is closed for the day. A counter door is the perfect solution—you can find many of the same features as are available in normal service doors.
  • Security Grilles - Security grilles allow line of sight into a specific area, but still provide security and protection. These are often used in shopping malls, airports and similar spaces where it is necessary to close down certain areas while leaving the main walkway open.
Rolling Doors


As you can see, there are a number of options when it comes to commercial doors. Taking the time to understand the types of available doors will make it easier to decide on which type is best for your particular structure.

Protect Your Premises With a Fire Door

Posted by Elizabeth Aceves on Sat, Jun 29, 2013 @ 02:25 PM

Fire-Rated Doors

Depending on the needs of your company, regular commercial doors may not provide the safety you need. If you work in an environment where you are worried about fire, one of the fire doors available here at The Overhead Door Company of The Meadowlands and NYC may be the perfect solution.

Fire Rated Door

Types of Doors

Fire doors come in many different styles. For instance, we carry fire-rated counter doors that are ideal for use in areas where you only need a door to reach from the ceiling to the counter. Another popular option is fire-rated insulated rolling service doors. These allow you to maintain a consistent temperature inside your building, provide security and have that protection against fire. For a finished look, the integral frame & sill fire counter doors are another option.

How a Fire Door Protects You

So why do you need a fire door anyway? A fire door is designed to slow the spread of both smoke and fire from one part of your building to another. This can give the occupants of the building a chance to escape, and may also protect valueable equipment or merchandise from damage during a small fire. A fire door is superior to a standard door in protecting because it is made of multiple layers and is both self-closing and self-sealing in an emergency situation.
