Rolling Steel Fire Door Protection for Fire Wall Openings

Introduction

This document describes the rolling fire doors available from DASMA rolling door manufacturers that are listed by UL or ITS (W-H), or Approved by FM Approvals. These fire doors may be attached to the jambs of masonry and/or non-masonry walls in accordance with the manufacturer's listing/approval. The Life Safety Code, designated as NFPA 101, prohibits this type door in exit openings.

There are four basic types of rolling steel fire door protection for fire wall openings, which are each described in this Technical Data Sheet. All rolling steel fire doors are designed to close automatically in the event of a fire, and the great majority are equipped with a governor to control the closing speed.

1. Rolling Fire Door A Rolling Fire Door consists of interlocking slats, a bottom bar, wall guides, a barrel assembly, an automatic release device, a governor, a hood, and a counterbalance mechanism along with supportive bracket plates. A Rolling Fire Door has an approval authority label, oversize label or oversize certificate with a fire rating. Typically, the fire rating is 4 hour, 3 hour, or 1-1/2 hour. A Rolling Fire Door may be used for both vehicular and pedestrian applications. Installation is covered in NFPA 80, Standard for Fire Doors and Other Opening Protectives, Chapter 11.

2. Rolling Counter Fire Door A Rolling Counter Fire Door consists of the same components as a Rolling Fire Door, with a smaller slat and smaller guides. The maximum fire wall opening is much smaller than for a Rolling Fire Door. A Rolling Counter Fire Door may close on sill angles, a masonry sill or on a labeled counter top. Installation is covered in NFPA 80, chapter 11. A Rolling Counter Fire Door can be used to close a conveyor opening or a pedestrian type wall opening.

3. Service Counter Fire Door A Service Counter Fire Door will bear a "Service Counter Frame and Fire Door Assembly" label. The wall opening limit is approximately 10 feet wide by 6 feet high. Typically, the fire rating is 1- 1/2 hr or 3/4 hr. Installation is covered in NFPA 80, Chapter 13. A Service Counter Fire Door is limited to non-pedestrian type wall openings. Service Counter Fire Door construction is a door curtain consisting of interlocking slats integrally mounted in a four-sided frame to form a labeled door and frame assembly. A Service Counter Fire Door will bear a "Service Counter Frame and Fire Door Assembly" label. The wall opening limit is approximately 10 feet wide by 6 feet high. Typically, the fire rating is 1- 1/2 hr or 3/4 hr. Installation is covered in NFPA 80, Chapter 13. A Service Counter Fire Door is limited to non-pedestrian type wall openings. Service Counter Fire Door construction is a door curtain consisting of interlocking slats integrally mounted in a four-sided frame to form a labeled door and frame assembly.

4. Fire Shutter A Fire Shutter is defined in NFPA 80 as a labeled door assembly for protection of a window opening in an exterior wall. A Fire Shutter can be a swinging door, a horizontal or vertical sliding door, or a rolling steel door. Installation is covered in NFPA 80, Chapter 12.

IMPORTANT Rolling fire doors shall be inspected and tested annually to check for proper operation and full closure. (Ref: NFPA 80)

Preventative Maintenance for Rolling Steel Gate Doors

Posted by Gray Decker Ariam on Sun, Jul 02, 2017 @ 04:03 PM

PREVENTATIVE MAINTENANCE FOR ROLLING STEEL DOORS

Preventative Maintenance for Rolling Steel Gate Doors overhead door company of the meadowlands and nyc service .jpg

 

BENEFITS OF PREVENTATIVE MAINTENANCE PROGRAM 

  • Increase operational efficiency, safety and reliability
  • Extend useful life of your equipment
  • Reduce probability of equipment malfunctioning
  • Decrease costly downtime
  • Decrease long-term repair expense
  • Establish relationship with experienced, service-oriented professionals

TROUBLESHOOTING GUIDE FOR ROLLING SERVICE DOORS

1. DOOR IS HARD TO RAISE BUT EASY TO LOWER. SOLUTION: Springs require more turns. Raise door to fully opened position and add spring tension (1/8 turn at a time) until the same resistance is felt lowering the door as is felt raising the door. Adjust tension wheel with steel winding bards 3’ long and diameter ½” or ¾”.

2. DOOR IS HARD TO LOWER BUT EASY TO RAISE. SOLUTION: Springs require fewer turns. Raise door to fully opened position and remove spring tension (1/8 turn at a time) until results listed in example 1 are achieved.

3. DOOR HANGS UP AT ENTRANCE INTO GUIDES. SOLUTION: a. Bellmouths might be out of position away from the headplate allowing endlocks to wedge. Loosen attachment nut and locate edge of bellmouth snug against headplate and tighten. b. Endlocks might have become loose and tilted out of position. Drill out loose fasteners and reattach with suitable fastener. c. Curtain might have been bent and damaged enough to wedge in guides. In some cases the bellmouths can be removed from the guide entrance and the curtain lowered outside of the guides and straightened. Be careful not to allow curtain to rapidly unwind off the counterbalance.

4. ELECTRIC OPERATOR STOPS TOO SOON; DOES NOT REACHT THE OPEN OR CLOSED POSITION. SOLUTION: Operator limit switch setting has become out of phase with the door. Reset the limit switches. See operator installation instructions for method of resetting limits.

5. OPERATOR DOES NOT RUN. SOLUTION: a. Verify that electric power is available to the operator. b. Verify 24 VAC control voltage form operator transformer. c. Verify condition of hoist interlock switch. d. Verify condition of slidebolt interlock switch.

RECOMMENDED PREVENTATIVE MAINTENANCE

To keep door in good working condition: Every three months

  • Oil all moving parts except the clutch mechanism on fire doors and the wool pile in the guides on rolling grilles or counter doors. The guides should be lubricated with a paste wax or silicone spray.
  • If electrically operated, check the operator gear reducer for oil leakage. If it is necessary to add oil, use Mobile Synthetic Oil (AGMA 7 #SHC 75W90).
  • Check the tension of the roller chain between the operator and the door sprocket (see Figure A). If too loose, loosen the operator mounting bolts and slide the operator to tighten the chain (see Figure B). Retighten the operator mounting bolts.
  • Oil the interior roller chain on operators without gear reducer.

Every six months

  • Oil all exposed roller chains, and on electric operators, dry lube the limit switch shaft threads.
  • All bearings provided with grease fittings should be lubricated. If so equipped, find bearings located in the drive bracket and tension end of the counterbalance.
  • Fire doors should be drop tested unless more frequent testing is required by other codes. Always use the Drop Test Instructions located inside the tension headplate cover.
  • On crank operated doors and grilles, the crank assemblies are sealed with grease and should not require lubrication.

The above frequency of maintenance is for normal operation. Severe duty or unusual operating conditions may require modification of the times between maintenance.

Rolling Steel Fire Doors: Drop Testing and Annual Follow-Up

Posted by Gray Decker Ariam on Fri, Mar 17, 2017 @ 07:51 AM

 

Rolling Steel Fire Doors Drop Testing and Annual Follow-Up door service.

 

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.

GUIDELINES

VISUAL INSPECTION:

Conduct a visual inspection for anything that may cause a hazard during testing or affect proper operation or resetting.

Verify that:

  1. Mounting and assembly bolts are not missing or loose.
  2. Welds and weld locations comply with installation method for fire door assemblies welded to steel jambs per manufacturer’s installation instructions.
  3. Fusible links are located per manufacturer's instructions.
  4. Guide assemblies have the required fire expansion clearance per manufacturer's instructions.
  5. Fusible links and sash chain/cable links are not painted or coated with dust or grease, cable is not kinked or pinched, chain is flexible and not twisted, and raceways are not obstructed.
  6. Smoke detectors/release devices function properly.
  7. Nothing that is not a part of the fire door assembly is attached to any part of the fire door assembly (suspended ceiling, light fixtures, ducting, conduits, framing and any other building materials).

Schedule Service

Check for damaged or missing components:

  1. Slats – bent; tears or holes; metal fatigue.
  2. Endlocks – missing; broken; bent; loose
  3. Bottom Bar – bent angles; loose bolts.
  4. Guide Assembly – bent angles or channels; loose bolts; curtain entry misalignment.
  5. Hood (and Flame Baffle when required) or Fascia – bent; rubbing curtain; holes; loose fasteners; metal fatigue; missing intermediate supports (when required).
  6. Automatic Closing Mechanism – missing, broken parts; drop or release arms tied, blocked or wedged.
  7. Operating Mechanism – worn, misaligned or poorly meshed gears; worn roller chains; misaligned or loose sprockets; loose bearings; broken parts; bent shafts.

OPERATIONAL CHECK

Open and close the door using normal operation. If you find the door is not properly balanced, or there is damage or missing parts that may create a hazard or prevent proper operation, have these conditions corrected before conducting a drop test.

DROPTEST

A drop test is required to confirm that the fire door will close automatically during a fire emergency. Use manufacturer's drop test instructions. Door must be fully open before drop test. The door must close fully so the bottom bar rests on the sill. The average closing speed must be between 6" and 24" per second. Test each automatic closing option for the fire door.

RESET THE DOOR

Reset the door per manufacturer's instructions. Open and close the door by normal operation. Drop test the door a second time, and reset again.

Ultimate acceptance of a fire door is the decision of the authority having jurisdiction, as defined in NFPA 80.
