FireGuard Moveable Fire Wall — Insulated Accordion Fire Wall

Won-Door FireGuard Moveable Fire Wall is a horizontal sliding accordion fire door which sits concealed away inside a pocket cavity, closing automatically under an alarm activation — FireGuard Moveable Fire Wall (MFW) is Won-Door’s insulated model fire door. 

When the Building Code restricts the size of penetrations in a fire barrier, the MFW is an alternative performance solution that is UL Certified as meeting the criteria required by ANSI/UL263 (ASTM E-119, NFPA No.251). FireGuard MFW provides designers a solution to open up spaces while still being able to quickly shut them down and create safe passages in the event of fire.  Two options are available; MFW1 (-/60/60) and MFW2 (-/120/120) with maximum opening dimensions of 9.144m wide and 3.740m tall.

The concealed pocket offers architects a completely hidden fire separation solution for compartmentalising buildings, while still maintaining clear unimpeded sight lines. Manufactured in America by Won-Door Corporation, FireGuard incorporates a steel twin walled design operating on twin top-hung tracks — there are no floor tracks required. Opening up design capabilities for architects in areas such as lobbies, atriums, stairways and corridors. A reliable and completely hidden solution.

  • Push to open Fire Exit Hardware located on both sides of the door (Fire Exit Hardware not a standard feature to FireGuard MFW)

Limitations on Use
  • Maximum opening dimensions of 9.144m wide and 3.740m tall
  • Not suitable for external use or exposure to outside elements

    • Continuously monitoring AC & DC power sources for missing, faulty or low supply
    • Detect if a charging circuit is bad or fuses have failed
    • Monitor the health of the drive chain
    • Monitor faults and inputs associated with Door Block and Key Switches
