A fire suppression system that includes a non-rigid pouch, a quantity of suppressant, a quantity of gas, and a pressurized gas source. The non-rigid pouch that includes an exterior surface and an interior space. The quantity of suppressant, the quantity of gas, and the pressurized gas source is contained within said interior space. The pressurize gas source is configured to increase the internal pressure of the non-rigid pouch by injecting gas into the interior space. The non-rigid pouch is configured to rupture when the internal pressure exceeds a predetermined threshold pressure.

A fire protection sprinkler including a frame body having an inlet, an outlet, defining an internal passageway extending between the inlet and the outlet along a sprinkler axis. A dome shaped deflector member is centered, axially aligned with the sprinkler axis, and spaced from the outlet. The deflector member has an outer surface and an inner surface that preferably includes: a peripheral region, a central region and an intermediate region. The intermediate region includes a primary deflecting surface, and a secondary deflecting surface that is surrounded by the primary deflecting surface. The deflector member provides for generation of a non-circular spray pattern defined by four zones of fluid density concentrically formed about the sprinkler axis.

An automated storage and retrieval system includes a rail system for guiding a plurality of container handling vehicles. The rail system includes a first set of parallel rails arranged in a horizontal plane and extending in a first direction, and a second set of parallel rails arranged in the horizontal plane and extending in a second direction, which is orthogonal to the first direction. The first and second sets of rails form a grid pattern in the horizontal plane including a plurality of adjacent grid cells. Each grid cell includes a grid opening defined by a pair of neighboring rails of the first set of rails and a pair of neighboring rails of the second set of rails. The automated storage and retrieval system includes a storage volume beneath the rail system. The storage volume includes storage columns for storing storage containers and the container handling vehicles are operable to retrieve a storage container from a stack of storage containers within the storage volume. A method of providing an operator access to a target storage position in the automated storage and retrieval system includes operating a master control system to allocate and instruct at least one container handling vehicle to remove storage containers along a first path between a position at a side edge or a top surface of the storage volume and the target storage position such that an operator can access the target storage position through the first path when the at least one container handling vehicle has removed the storage containers along the first path.

Fire protection systems and methods of fire protection systems for protection of a stored commodity. The systems and methods included a plurality of fluid distribution devices disposed above the stored commodity and configured for selective identification and controlled actuation in response to a fire. The systems have a hydraulic demand defined by at least one of: i) a hydraulic design area having a minimum operational area of less than 768 square feet; or ii) less than twelve hydraulic design devices.

A fire suppression sprinkler has a deflector with two slots aligned with the deflector support arms. The two slots extend from opposite sides of a periphery of the deflector along a common line which passes though the sprinkler's flow axis. The two slots extend to a point which underlies the sprinkler's nose at the ends of the support arms to which the deflector is attached. Other slots extend from the periphery of the deflector along lines which do not pass through the sprinkler flow axis. The other slots extend to points in spaced relation to the nose. Regions of the deflector periphery surrounding the first and second slots are closer to the flow axis than other regions of the periphery. The area of each of the first and second slots is greater than the area of any other slot in the deflector plate.

An automated storage and retrieval system includes a rail system, a master control system, and a plurality of remotely operated vehicles. The rail system includes a first and second set of parallel tracks arranged orthogonally in a horizontal plane. The master control system is configured to keep track of any remotely operated vehicle operating on the rail system. The plurality of remotely operated vehicles handling storage containers, which operate on the rail system, each include first and second sets of wheels for transport on the rail system, and a fire detection device configured to transmit data from the fire detection device to the master control system. The master control system includes a processing device for processing the data from the fire detection devices so as to create a heat map of the automated storage and retrieval system.

A container is for storing at least one mobile device being recharged. The container has a self-closing door for closing the container, a sensor for detecting a fire inside the container, and an actuator for retaining the door in an open position. The actuator is adaptable to release the door when a fire is detected by the sensor. A mobile device may thus be safely recharged while its user is unaware or asleep.

An area is set as an interference area, in which a transport vehicle is located in a state in which a portion of the transport vehicle overlaps a door trajectory which is a movement trajectory of a fire protection door. A control portion that controls a subject vehicle, which is a transport vehicle to be controlled, prohibits the whole subject vehicle from entering the interference area if it is determined, based on another-vehicle information, which is information of a traveling state of another vehicle that is different from the subject vehicle, and information regarding the interference area, that the interference area is present between the another vehicle located forward of the subject vehicle and the subject vehicle, and that a stoppable area is not secured between a rear end position of the another vehicle and the fire protection door.

A system includes a fire panel 12 having a loop driver. A combined detection and suppression loop 18 is connected to the loop driver. A plurality of fire detection devices 14 and a plurality of fire suppression devices 19 are coupled to the detection and suppression loop 18. The fire suppression devices 19 includes multiple sprinkler devices 19, each of the sprinkler devices 10 including a sprinkler bulb 100 and a circuit 120. The circuit 120 of the sprinkler device 10 is detectable via the fire panel 12 using the detection and suppression loop 18 in order to provide information from the sprinkler device 19 to the fire panel 12.

A sprinkler includes a frame, a deflector member, a sealing assembly, and a releasing mechanism for a controlled actuation. The releasing mechanism includes a hook member, a strut member, a load member, a link member, and an actuator. The link member surrounds or frames the strut and hook members and holds the members in a static relationship of an unactuated configuration. A preferred link member includes a single central slot through which each of the hook member and the strut member extend. The actuator is arranged with respect to the link member to separate the hook and strut members and break the link member upon operation of the actuator.
