The invention relates to a fire protection robot (1, 2) for performing a fire protection action. According to the invention, the fire protection robot comprises a communication unit (11) for receiving an instruction signal that represents a target site, and a control unit (10), which is configured to navigate the fire protection robot (1, 2), preferably autonomously, based on the instruction signal, along a navigation path to the target site, wherein the control unit (10) is further configured to detect at least one door (3) along the navigation path and to autonomously open the at least one door (3) in response to the detection.

Embodiments of this application provide a fire-fighting switch device and a fire-fighting system, which are applied to the field of fire-fighting. The fire-fighting switch device includes a plurality of fire detection switch units, where the fire detection switch unit includes one or more fire detection switches, the one or more fire detection switches form at least one switch path, the fire detection switch is configured to turn on when a fire is detected, and any one of the switch paths is configured to transmit a voltage signal to a fire-extinguishing device when all of the fire detection switches on the switch path are turned on. In this solution, when a fire is detected by one fire detection switch unit, the fire-extinguishing device can be controlled to extinguish the fire provided that all fire detection switches on one switch path in the fire detection switch unit are turned on.

The present invention discloses a fire extinguishing system for a battery pack, including a detection control apparatus, a fire suppression apparatus, and a hydrant water extinguishing apparatus. The detection control apparatus is disposed inside or outside a battery pack. The fire suppression apparatus and the hydrant water extinguishing apparatus are disposed outside the battery pack. The detection control apparatus is connected to the fire suppression apparatus. The hydrant water extinguishing apparatus is connected to the fire suppression apparatus. Beneficial effects: It is ensured that initial fire can be suppressed and later reignition can be resolved, so that fire extinguishing is adequate. Fire is directly extinguished at a core position inside the battery pack. An exhaust filter device gains valuable time after initial fire extinguishing.

A system for detecting and verifying an environmental anomaly within a shipping container (transported on a transit vehicle having an external transceiver) has wireless sensor-based ID nodes at different locations within the container and multiple command nodes mounted to the container. A first command node is programmatically configured to be operative to detect the sensor data broadcasted from the ID nodes; responsively identify the anomaly based upon the sensor data detected by that command node; and transmit a validation request to another command node. The other command node is configured to be operative to also detect the sensor data broadcasted from the ID nodes; receive the validation request from the first command node; verify the anomaly in response to the validation request and based upon the sensor data detected by the second command node; and broadcast a verification message based upon whether the anomaly for the shipping container is verified.

An apparatus, system, and method for providing an improved fire sprinkler is disclosed. A solenoid valve is provided that couples to a pipe system of the fire sprinkler system. The solenoid valve is operably associated with at least one of a heat detector such that the solenoid valve opens and water is permitted to flow through the solenoid valve and pipe system when a signal is received from the at least one of a heat detector and a smoke detector. The system may be activated by 24 volts direct current, which increases system reliability and dependability.

The compact cooling and extinguishing system is designed to be arranged in a protected device, in particular electrical switchboards with a DIN rail, wherein the compact automatic cooling and extinguishing system consists of a carrier (14) containing inside a pressurized cooling and extinguishing medium, wherein the medium is based on chemical extinguishing agents, which are characterized in that during initiation their temperature, when escaping the carrier, is in negative values, i.e. temperature below 0° C., below the freezing reference point, the system is further provided with a pressure indicator for monitoring the condition of the cooling and extinguishing medium, wherein the compact cooling and extinguishing system is further provided with a first temperature, pressure or smoke switch (15) and a valve (5), which is connected to the carrier of the cooling and extinguishing medium by connection (18), wherein the valve is further provided with a nozzle (6) for release of the cooling and extinguishing medium into the space of the protected device and the valve (6) is further connected to the relay (7). The system is provided with an external power supply (13). The first switch (4) is set to open the valve (5) when the given temperature value is reached in the protected device. In a preferred embodiment, the compact cooling and extinguishing system is provided with a compact cover (2) for mounting on a DIN rail.

According to an aspect, a fire suppressant system includes a first fire bottle in operable communication with a first cockpit control switch via a first channel, and a first sensor-based switch via a second channel. Additionally, the fire suppressant system includes a second fire bottle in operable communication with a second cockpit control switch via a third channel, and a second sensor-based switch via a fourth channel.

A protective device includes a pipe in a pipe system for transmission of a flow of a fluid from an upstream end of the pipe system to a downstream end of the pipe system. The devices includes a pipe insert, disposed within the pipe system between the upstream and downstream ends. The pipe insert has a cylindrical body. A valve is within the pipe insert and is moveable between open and closed positions. The open position opens the pipe insert, enabling transmission of the flow of the fluid, and the closed position occludes the pipe insert, disabling transmission of the flow of the fluid. A sensor is within the pipe insert for disposition within the flow of the fluid to detect a target compound in the pipe insert. The valve moves from the open position to the closed position when the sensor detects the target compound.

An automatic fluid spray system includes a water pump fluidly connected to a water source, a return conduit positioned to allow water exiting the water pump to return to the water source, and a spray line comprising a conduit and a plurality of spray elements. The automatic fluid spray system also has a valve that allows water exiting the water pump to either return to the water source or enter the spray line and one or more temperature sensors in electrical communication with a control circuit. The control circuit is electrically connected to the valve and configured to move the valve to supply water to the spray line when a temperature of at least 150° F. is detected by the one or more temperature sensors.

A mesh network fire suppression system includes a coordinator node configured as a control unit. The coordinator node includes a transceiver, a processor, and a memory coupled to the processor.
