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.

The object of this invention is a ventilation duct unit (1), which comprises an inlet (2), an outlet (3), a flow channel (4), which extends from the inlet to the outlet, and which is delimited by a wall (5) between the inlet and the outlet, a closing part (6), which is arranged into the flow channel, and which in open position enables flow in the flow channel (4), and in closed position prevents flow in the flow channel, and a closing member (12), which as a response to detecting fire, sets the closing part (6) to a predetermined position. In order to test the functioning of the closing part of the ventilation duct unit simply, easily and quickly in case of fire, the ventilation duct unit comprises a position switch (20) of the closing part (6), which is in first state, when the closing part (6) is in said predetermined position, and which is in second state, when the closing part (6) is not in said predetermined position, and a fire testing unit (21), which at predetermined times triggers testing of the fire safety functions, wherein the closing member (12) sets the closing part (6) to said predetermined position, and which after triggering testing of the fire safety functions indicates that testing of the fire safety function was successful, if it detects that the position switch (20) of the closing part (6) is in first state.

A control mechanism includes an actuator having first and second positions, a resilient member arranged to bias the actuator toward the second position, and an input cable. The input cable is arranged along a serpentine path and is connected to the actuator, the input cable arranged to retain the actuator in the first position using tension applied by a plurality of detector cables along the serpentine path of the input cable. Fire detector connector modules, fire suppression systems, and methods of integrating detector cables into control mechanisms are also described.

An inspection system for an HVAC device includes an HVAC duct section, a damper positioned with the duct section, an actuator for selectively moving the damper to a closed position, and a verification camera for recording the position of the damper with a date stamp and a time stamp. The actuator is further configured to move the damper to its open position, and the verification camera is further configured to record the open position of the damper with a second date and time stamp.

A storage system is disclosed where goods can be stored in containers and the containers are stored in stacks. Above the stacks runs a grid network of rails (e.g., tracks) on which load handling devices can run. To take containers from the stacks and deposit then at alternative locations in the stacks or deposit then at stations where goods may be picked. The framework may be provided with one or more of the following exemplary services: power, power control, heating, lighting, cooling, sensors, and data logging devices. The provision of these services within the framework rather than across the system as a whole, can allow for flexibility in storage whilst reducing cost and inefficiency.

A fire barrier includes an inflatable base deployable from an empty state to a fully inflated state and a first row of panels including a plurality of first panels disposed on the inflatable base. The base supports the plurality of first panels in an upright state when the inflatable base is in the fully inflated state, thereby forming a wall having a front side and a rear side opposing the front side. Each of the plurality of panels is independently elastically bendable with respect to the inflatable base. A coating of an infrared reflective material is disposed on each of the plurality of panels on the front side of the wall.

A fire detection and suppression system operates in independent autonomous modes or under human command. Optical, thermal and laser based sensors detect fire conditions. Anemometers and thermometers detect environmental conditions, allowing the system to adjust the flow of fluid from the system to the targeted flame or condition. Algorithmic analysis of the input data in connection with such preselected thresholds permits rapid detection of fire conditions and in automatic modes triggers a suppression response. A feedback loop enhances adjusts for dynamic flame and environmental conditions.

A fire suppression apparatus for a vehicle includes a sensor for detecting a condition of an object mounted in the vehicle, a controller configured to determine whether the condition of the object mounted in the vehicle, which is detected by the sensor, satisfies a predetermined criterion for determining outbreak of fire and to output a control signal for suppression of the fire when the condition of the object satisfies the predetermined criterion, and a spread bag apparatus mounted in the vehicle, which is configured to unfold a collapsed spread bag toward the object in response to the control signal from the controller such that the unfolded spread bag hermetically covers the object, thereby suppressing fire at the object.
