In one or more arrangements, a system is presented for preventing the spread of fire through a conveyor opening in a fire wall. In one or more arrangements, a fire door system is connected to the fire wall and/or conveyor proximate to the conveyor opening. The fire door system includes a door assembly, a door frame assembly, and an actuator. The door frame assembly is connected to the fire wall, covers portions of the opening below the conveyor and between belts of the conveyor, and forms a door opening above the conveyor. The door assembly is configured to move between a closed position, where door assembly covers the door opening, and an open position, where the door assembly at least partially uncovers the door opening. The actuator is configured to cause the door to be moved to the closed position in response to fire.

A fire suppression system for an enclosed space, such as within a lavatory of a vehicle, includes a first inner gate, a second inner gate coupled to the first inner gate to define one or more air channels therethrough, and a temperature-responsive device coupled to one or both of the first inner gate or the second inner gate. The temperature-responsive device is configured to be in a first state below a predetermined temperature threshold, and a second state above the predetermined temperature threshold. In the second state, the second inner gate is moved relative to the first inner gate to close the one or more air channels.

A closure system for door openings defined in a wall (P) and comprising: a quick-opening door (1) adjustedly installed within the door opening (H) and featuring a flexible roll-up sheet (11), an upper casing (12), and vertical uprights (3) equipped with guides (31) for the displacement of the flexible sheet (11); a fire door (2) installed at one side of the wall and comprising at least one fireproof layer (21, 23), for the opening and closure of the door opening (H), a perimeter frame constituted by the vertical uprights (3) and a rearward fireproof cover (4) of the upper casing (12) of the quick-opening door (1).

In example implementations, a guide member is provided. The guide member includes a first portion to receive a first fastener to a second guide member to form a guide assembly having a gap, wherein an endlock of a fire shutter is positioned within the gap, a second portion to receive a second fastener to a wall, a third portion folded against the second portion, a fourth portion bent at 90-degrees or greater to the third portion.

A fabric fire rated door is described. The door utilizes a fire resistant fabric curtain with an end lock attachment. A tubular steel shaft is driven by an internal tube motor. The shaft is supported to minimize deflection. Single door shafts can also be joined together with a coupler shaft to create infinitely wide doors. The coupler shaft is spring loaded to act as a take up reel for a coupling curtain which will overlap each adjacent single door shaft. All curtains are attached to the same bottom bar. A hood covers the shaft, curtain, and the supports that run across the width of the door. The curtain travels over these horizontal supports as it drops down through the hood opening. The horizontal supports keep the curtain in position for proper seal during a fire/smoke event.

A system that deploys attic vent covers when there is the immediate threat of fire, as well as methods and device relating thereto, is disclosed. This system includes varied cover types and deployment methods to utilize with a range of attic vents found suitable for use in residential and commercial construction.

An autonomous grid storage system (1) arranged in a warehouse space (12). The autonomous grid storage system is divided within the warehouse space, for example on a single floor of said space, into a plurality of sub grids (10a/10b) separated by fire walls (18). One or more bridges (14) pass through openings in the fire wall to allow bin handling vehicles (210/301) to traverse between the sub grids. The openings (20) are provided with closable fire door (22).
