  1. Fire shutter structure
    A fire shutter is one that, with its frame, meets fire integrity for a set time. It is a fire divider. A vertical shutter normally rolls up in the shaft box above the opening; in a fire it drops to stop the spread through the opening. It is usually set around escalators, at atria to each floor’s corridor, lobbies, rooms, and where a firewall divider is needed.

  2. Fire shutter parts
    It is made of curtain plate, seat plate, rail, bracket, shaft, box, control box, motor, limiter, lintel, manual quick-release, button switch, and safety device. Linked devices: smoke and heat detectors and the fire link system.

  3. Fire rating classes
    By fire limit: ordinary steel (limit >= 2h), composite steel (limit >= 3h), premium (limit >= 4h). Ordinary steel used as a divider needs sprinkler protection.

  4. Control operation
    Auto: after the detector acts, in link mode, a divider shutter drops to bottom; a shutter on an escape path drops to 1.8 m above floor first, then after a heat detector acts, drops to bottom.
    Mechanical: take the chain, pull the shutter-side lock chain down, the shutter descends; pull the other side, it rises.
    Manual: open the box on either side or nearby, press “up” (or triangle) to roll up, “down” (or the other symbol) to descend, middle to stop. Or at the fire control room press the manual key for the module that drives the shutter down; when in place it sends feedback to the room.

  5. Where fire shutters are set
    By process: besides firewalls, where two fire zones have no firewall, set a shutter. Usually at:
    (1) Enclosed escape stairs to corridor; enclosed elevator lobbies to anterooms and anterooms to corridor.
    (2) Check doors of cable, pipe, smoke, trash shafts.
    (3) Doors on firewalls and partition walls dividing fire zones; when a firewall or fire door is hard to fit, use a fire shutter with water curtain protection.
