A booth with a ceiling and an inside space includes: a fire extinguisher that is positioned in an opening portion formed in the ceiling, has a fire extinguisher main body storing a fire-extinguishing agent, and sprays the fire-extinguishing agent into the inside space; and a support tool that is disposed on the upper surface of the ceiling so as to surround the opening portion and has an opening being smaller than the maximum outside diameter of the fire extinguisher main body and corresponding to the outside shape of at least a portion of the fire extinguisher main body. The fire extinguisher main body is supported by the support tool from the lower side in the gravitational direction.

Systems and methods of ceiling-only fire protection of a storage structure are provided. The system can include a plurality of fluid distribution devices disposed in a grid pattern beneath a ceiling and above the storage structure. The plurality of fluid distribution devices can include a frame body, seal assembly and actuator. The system can include a fluid distribution system including network of pipes interconnecting the plurality of fluid distribution devices with a water supply. The system can include a plurality of detectors to monitor the storage structure for a fire. The system can include a controller coupled to the plurality of detectors to detect and locate the fire, and coupled to the plurality of fluid distribution devices to identify and control operation of a select number of the plurality of fluid distribution devices that define a discharge array above and about the fire.

A fire suppression system in which the water supply line is fitted with repeating arrays or groups of sprinkler heads. Each array is composed of at least two side-discharge sprinklers. The side-discharge sprinklers in each array are aimed so that their coverage areas point in opposite directions. Each side-discharge sprinkler includes a lateral heat shield. The lateral heat shield has a concave heat-concentering side that focuses radiant heat toward the sprinkler's trigger, and a convex heat-scattering side that disperses radiant heat away from the trigger. In some embodiments, the array can include one or more vertical-discharge sprinklers. The vertical-discharge sprinkler may include a heat collector to facilitate early activation of its trigger. The fire suppression system is advantageous in high-challenge applications like facilities where large quantities of combustible items are stored in close proximity, such as in warehouses and attics.

A mobile automotive spray booth having a collapsible enclosure and a fire suppression system. The fire suppression system includes a control unit, a fire detection cable or cable assembly in communication with the control unit, and a fire extinguisher assembly in communication with the control unit. The fire detection cable or cable assembly extends across at least a portion of the collapsible enclosure, and is configured to detect a fire within the collapsible enclosure. The control unit is configured to activate the fire extinguisher assembly to extinguish the fire upon detection of the fire by the fire detection cable or cable assembly. The fire detection cable or cable assembly is configured to bend to allow the collapsible enclosure to collapse from an expanded configuration to a collapsed configuration without removal or disassembly of the fire detection cable or cable assembly.

In one implementation, a computer-implemented method includes receiving, at a computer system, information that indicates that a fire has been detected in a building and that a fire suppression system within the building has begun dousing the fire; monitoring sensor information from one or more sensors located within the building; determining, by the computer system and based on the sensor information, whether the fire has been extinguished; activating, in response to determining that the fire has been extinguished, a feature to turn off a water supply to the building, the feature being presented on a computing device for a user who is associated with the building; receiving, after activating the feature and from the computing device, a command to turn off the water supply; and transmitting, by the computer system, a control signal that causes an electromechanical device to close a water valve within the building.

A dry sprinkler includes a flexible tube section that maintains a pressurized fluid, such as a liquid antifreeze solution, between a first end and a second end. A first seal prevents fluid from a supply line from entering the flexible tube section. The first seal is maintained in a sealed position by a pressure of the pressurized fluid. A sprinkler head is coupled to the second end of the flexible tube section, and includes a frame, an output orifice, a deflector, a second seal that seals the output orifice, and a thermally responsive element configured to maintain the second seal in a sealed position when the thermally responsive element is in a non-responsive state. A differential pressure controller maintains a ratio between the pressure of the pressurized fluid in the flexible tube section and a pressure of a supply fluid in the supply line to at least a certain ratio.

A GPS tracking and mapping wild fire defense system network configured for defending homes and neighborhoods against threat of wild fire by proactively spraying environmentally-safe anti-fire (AF) chemical liquid on property surfaces to inhibit fire ignition and flame spread in the presence of wild fire. The GPS tracking and mapping wild fire defense system network includes: a command center in operable communication with a wireless communication network; and one or more GPS-tracked anti-fire liquid spraying systems, each having an integrated supply tank and a spray pump deployable at properties having building structures, for spraying the properties with environmentally-clean anti-fire chemical liquid using a spray nozzle assembly connected to said spray pump by way of a fluid connection. The system network further includes: a GPS system for transmitting GPS reference signals from a constellation of GPS satellites deployed in orbit around the Earth, to a GPS transceiver installed aboard each GPS-tracking anti-fire liquid spraying system, for GPS processing and GPS-coordinate location; and one or more mobile computing systems, each for use by a registered user including property parcel owners, spray contractors, and other stakeholders on the system network, to request and receive services supported by said system network. Each mobile computing system has a display screen supporting: messaging services; display of maps indicating where wild fires have been identified and mapped, tracked and ranked in terms of risk to the user and GPS-specified property; and scheduling of spray task to be performed, and recording tasks that been completed, and which are in progress, on the GPS tracking and mapping wild fire defense system network.
