A fire extinguishing system for a lithium battery energy storage unit based on stagewise warning and multiple spraying includes a power management system, a warning control system connected to the power management system and a fire extinguishing device connected to the warning control system. The fire extinguishing device is externally connected to a temperature-sensing fire detection tube, a large-flow release pipeline and a local release pipeline. The warning control system is externally connected to a local data collection module and a lithium battery energy storage pack. The fire extinguishing system of this application is designed to perform cyclical detection according to fire signals, in which a starting signal can be repeatedly sent to achieve multiple starting, so as to suppress a lithium battery fire for a long time and solve the problem of re-ignition.

Concealed fire detector suspension apparatus has a fixing collar and a plurality of radial locking tabs insertable therethrough. A removeable fixing foot is configured for engaging a stem of an upright support for a fire detector and having a peripheral outward locking formations which mechanically interlock with corresponding inward locking formations on an inner surface of the fixing collar. In use, the apparatus is configured for installing the fixing collar via a ceiling cutout, inserting the radial locking tabs through the fixing collar from the interior thereof to clamp the ceiling, inserting the upright support through the fixing collar and locking the outward locking formations of the fixing foot to the corresponding inward locking formations of the cylindrical body, thereby supporting the upright support through the ceiling.

Systems and methods are described for monitoring, detecting, and initiating a response to an environmental anomaly within a shipping container of packages involves sensor-based ID nodes, a command node and an external transceiver on a transit vehicle. Each ID node generates and broadcasts sensor data on environmental conditions proximate the respective ID node within the shipping container. The command node detects the sensor data from each ID node and compares it with locally maintained context data (an environmental threshold condition) for that ID node to detect the environmental anomaly when sensor data exceeds a respective threshold condition. The command node then generates a layered alert notification related to the environmental anomaly identifying a targeted mediation recipient and targeted mediation action, and establishing a mediation response priority. The command node initiates a mediation response related to the targeted mediation action by transmitting the layered alert notification transmitted to the external transceiver.

A fire extinguishing system for a tire of a vehicle is capable of effectively responding to a fire in all tire areas of the vehicle, and of spraying fire extinguishing agent selectively only for the tire having the fire, thereby performing effective fire extinguishing. The fire extinguishing system includes: a fire detection sensor configured to detect the fire in the tire of the vehicle; a fire control unit configured to receive a signal output from the fire detection sensor and to output a control signal for spraying fire extinguishing agent when the fire control unit determines a fire occurrence; and a plurality of fire extinguishing agent sprayers configured to spray the fire extinguishing agent toward the tire having the fire according to the control signal output by the fire control unit, in a state of being filled with the fire extinguishing agent therein

A grommet is provided for use in a fire and overheat detection system (FODS) clamp. The grommet includes an elongated body defining a central aperture and a slit. The elongated body includes wire mesh.

Embodiments of the present invention are related to an automated structure and curtilage protection system including a mechanical system hub, a piped network, a plurality of spray nozzles, and a remote user control portal. The mechanical system hub includes at least one of a control center, a pump, a pressure tank, a plurality of controllable valves, and a chemical injector assembly. The system is structured to autonomously take system action depending on a hierarchy of preprogrammed threat levels. The system is also structured to autonomously deliver water at set time intervals onto a structure and curtilage when instruction sets corresponding to relative threat levels have been activated. The system is further structured to autonomously deliver chemically infused water solely onto a structure's curtilage for a set time interval when instruction sets corresponding to a relative threat level have been activated.

Fire-fighting device with at least one generator arranged for discharging fire-fighting agent, an electrically triggerable ignition means arranged in the generator, the ignition means being controllable via an at least two-pole control connection. A bypass circuit electrically arranged at the control connection detects a tiggering of the ignition means and closes a switch when the ignition means is released.

A package command node detects an environmental anomaly related to a shipment package for transport within a shipping container on a transit vehicle having an external transceiver. The package command node has a command node housing disposed with the package, a processor within the housing, a memory maintaining package command node environmental detection program code, and a wireless transceiver communication interface that communicates with sensor-based ID nodes generating sensor data from different parts of the container. The package command node's processor is programmatically configured to detect the ID node sensor data; identify the anomaly when the detected sensor data indicates an environmental condition that exceeds an environmental threshold; generate an alert notification related to the anomaly; and transmit the alert notification to the external transceiver to initiate a mediation response related to the environmental anomaly.

A blanket apparatus is described for enhanced detecting of an environmental anomaly relative to a shipping container temporarily maintaining packages. Generally, the apparatus includes a detection blanket disposed proximate the packages and multiple sensor-based ID nodes integrated as part of the detection blanket in a geographically disperse configuration relative to the detection blanket. Each of the sensor-based ID nodes has a processor, memory (with ID node monitoring program code), an environmental sensor, and a wireless radio transceiver. The sensor generates sensor data related to an environmental condition adjacent the sensor and indicative of the environmental anomaly when the sensor data generated is above a threshold condition for that sensor. The transceiver is configured to access and broadcast the sensor data generated in response to a report command from the ID node's processor when the ID node processor executes the ID node monitoring program code.
