Fire Doors

R&S Fire Doors combine the durability, security, efficiency and space saving advantages of a rolling service door with the added life and property saving benefits of automatic fire protection. Underwriters Laboratories, Warnock Hersey and Factory Mutual up to 3-Hour/Class ‘A’ Label or Oversize Certificate of Compliance is furnished standard.

Fire Doors are designed to close automatically from a fully open position. Fire Doors are not designed for use in high cycle applications.

Many options are available including Electronic Release Devices, smoke detectors, battery back- up systems, perimeter gasketing, vision lites, and more. Call for more info.

Specifications:

  • Mounting: Face of wall or between jamb
  • Operation: Push-up to 8′ wide and high and chain hoist on larger sizes is standard; awning crank, crank box or motor operation is optional
  • Automatic Closing: Thermally activated by 165 degrees fusible links, with the closing speed regulated by a governor device operative only during automatic closing
  • Curtain: Interlocking slats are roll formed from galvanized steel coil. Gage of slats is as required by the listing. Endlocks are riveted to slats to maintain curtain alignment. Bottom of curtain is reinforced by a double steel angle foot piece.
  • Guides: Steel channels or structural steel angles from curtain guides are bolted to structural steel wall angles. Sizes of guides are as required by the listing.
  • Brackets: Steel plate brackets are bolted to wall angles to support curtain and barrel and provide mounting for hood.
  • Hood: Formed from minimum 24 gage galvanized steel sheet, reinforced with top and bottom flanges to limit deflection. A thermally released integral flame baffle is provided when required by the listing.
  • Locking: Chain lock with chain operation and slide bolt locks with push-up or crank operation.
  • Finish: Slats and hoods are pre-finished with a baked on grey polyester primer before forming. Foot piece, guides and brackets receive one coat of rust inhibiting black primer.

Fire Door Options

Smoke Detectors: photoelectric (detects smoke and heat) or ionization (detects combustion particles) require connection to a release device with compatible voltage

Release Devices: Electro-thermal and McCabe links (normally open circuits); electro-magnetic and time delay failsafe releases (normally closed circuits)

Release Device: provides automatic closing and testing of motor operated counter fire doors upon activation by a detector or alarm; eliminates the need for mechanical release and reset unless there is a power loss; allows for a cycling sequence of the door in the event an obstruction is encountered upon closing (see Fire Doors)

Perimeter Gasketing: brush seals factory applied to guides and footpiece, field installed on header, to aid in smoke and draft control

Vision Lites: single or multiple 4″ wide cut-outs, glazed with clear wire glass (1 1/2 hour rating)

Powdercoat Finish: a durable and decorative finish for steel or aluminum surfaces. It provides longer life and requires less maintenance than a standard finish. Powder coating is available in a variety of colors for use on many products. Consult factory for color selection, applications and limitations.

VIBRATECH: ViscousSpeed Governor: available on R & S Manufacturing, Inc. fire doors for new construction and retro-fit. Viscous speed governor is a patented device allowing for a smooth and quiet descent of fire doors, replaces standard ductile iron governor, and recommended on larger certificate size fire doors, either manual or motorized operation.

 


 

Fail Safe Release Devices:

Fail Safe Release Devices

LM21XPBB

Features

The XPBB release device provides the functionality of a standalone fire alarm system including battery backup for installations prone to power outages or the existing alarm system is unable to support the door release system. Internal Battery Backup allows the release device to stand alone from the fire alarm system and act independently in the event of a power outage. The system can provide 24VDC power for up to four smoke detectors and two horn/strobes, mounted on either side of the door. Programmable delay settings, close door detection, diagnostic LEDs, localized testing, and reset capabilities are also standard.

  • UL864 Revision 9 compliant
  • Programmable DIP switch delay setting – either 10, 20, 30, or 60 seconds delay of door release to permit passage clearance
  • Inputs for normally open 2- or 4-wire detectors and 4-wire normally closed detectors
  • Trouble and alarm relays for communication with the fire alarm control panel, if required
  • Audible trouble sounder to indicate when the release device is not operational
  • On board diagnostic LEDs for easy troubleshooting
  • Testing function allows routine fire door testing without requiring activation of the smoke detector
  • Model LM21XPBBVB is equipped with a voice board to broadcast a pre-recorded voice evacuation message

LM21AFCB

Features

The AFCB fire door release device works in conjunction with a standard, commercial electromechanical or solid-state operator to create an enhanced, yet economical, fire door operating system. For use with motorized doors incorporating a reversing electric safety edge. This 120VAC device can power up to four smoke detectors and two horn/strobes or speaker/strobes. This system combines state-of-the-art functionality and advanced features typically found on special-order fire door operators.

  • UL864 Revision 9 compliant
  • Programmable DIP switch delay setting – either 10, 20, 30, or 60 seconds delay of door release to permit passage clearance
  • Internal Battery Backup system
  • Obstruction cycling – works in conjunction with the door’s electrical safety edge, reversing the door if an obstruction is encountered
  • Motor voltage sensing
  • Test keyswitch – permits floor-level testing of the system
  • Model LM21AFCBVB is equipped with a voice board to broadcast a pre-recorded evacuation message

LM21XP

Features

The XP fire door release device in conjunction with a fire alarm panel provides a fail-safe release mechanism for the fire door or shutter. The device requires 24VDC power from an approved UL1481 regulated power supply with Battery Backup, such as a fire alarm control panel. Therefore, installation will require coordination with a fire panel installer.

  • UL864 Revision 9 compliant
  • Programmable DIP switch delay setting – either 10, 20, 30, or 60 seconds delay of door release to permit passageway clearance
  • Close door detection – prevents door release if the door is kept in the closed position and eliminates door reset service calls or potential system damage
  • On board diagnostic LEDs for early troubleshooting
  • Testing function allows routine fire door testing without requiring activation of the central alarm system; easy reset function returns the device to a standby state
