A system to mitigate false trips of a valve that supplies water to a piping system in a fire suppression system includes at least one edge device, a control circuit, and at least one user device. The at least one edge device monitors a parameter corresponding to at least one of a corrosion, a presence of water, a differential pressure across the valve, and a temperature in the piping system of the fire suppression system. The control circuit includes one or more processors and a memory storing instructions that, when executed by the one or more processors, cause the control circuit to receive an indication of the parameter monitored by the at least one edge device, predict whether a valve tripping event is expected to occur based on the received indication, and in response to predicting that the valve tripping event is expected to occur, provide the prediction that the valve tripping event can occur for remedial action. The at least one user device presents display data regarding the prediction.

A method of temporarily operating sprinklers and mobile sensors during buildings/facilities alterations, renovations, additions, repairs, rehabilitations, relocations and any other similar activities where personnel may trigger sprinkler systems through accidental actions (or inactions) during their chores. This minimizes the possibility of damages during the building's construction/renovation.

A fire-fighting system includes a pump, a nozzle for directing fluid flow from the pump to a target area, a discharge valve controlling fluid flow between the pump and the nozzle, a sensor coupled to the nozzle, and a controller communicatively coupled to the sensor. The sensor detects movement of the nozzle and generates a signal indicative of the detected movement. The controller communicatively coupled is configured to receive the signal from the sensor, and control at least one of the discharge valve, the pump, and the nozzle based on the detected movement of the nozzle.

A fire prevention system connected to a building, the fire prevention system including a plurality of sensors removably connected on at least a portion of the building to detect at least one of a fire and smoke in response to at least one of the smoke moving toward at least one of the plurality of sensors, an increase in a temperature level of air, and an increase in a temperature level of at least one surface of the building, a plurality of vapor dispensing pipes disposed on at least a portion of the building to dispense water onto at least one surface of the building in response to at least one of the plurality of sensors detecting at least one of the smoke, the increase in the temperature level of the air, and the increase in the temperature level of the at least one surface of the building, and a plurality of fire retardant dispensing pipes disposed on at least a portion of the building to dispense the fire retardant onto at least one surface of the building in response to at least one of the plurality of sensors detecting at least one of the smoke, the increase in the temperature level of the air, and the increase in the temperature level of the at least one surface of the building.

A fire extinguishing apparatus of a vehicle is capable of effectively extinguishing a fire by uniformly and directly spraying a fire extinguishing agent in a wide range to a battery cell covered with an external structure in a vehicle. The fire extinguishing apparatus includes a cover, a spray nozzle, a controller, a driving device, and a fire extinguishing agent supplying device.

A method of operating a suppression system includes opening a discharge valve associated with a pressurized vessel containing suppression agent in response to detection of a hazardous condition within an area being monitored, releasing suppression agent into the area being monitored via a discharge nozzle, and detecting that the hazardous condition is no longer present in the area being monitored. The discharge valve is closed by the actuator in response to detecting that the hazardous condition is no longer present in the area being monitored.

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.

A modular fire suppression unit includes a housing, an off-gas detector, a fire suppression apparatus, and a controller. The off-gas detector is provided within the housing and is configured to obtain air samples and detect a presence of off-gas in each air sample. The fire suppression apparatus is provided within the housing and configured to provide a fire suppression agent to a space. The controller is provided within the housing and is configured to receive signals from the off-gas detector indicating whether off-gas is detected in each of the air samples. The controller is also configured to activate the fire suppression apparatus to provide the fire suppression agent to the space in response to detecting off-gas in one or more of the air samples. The modular fire suppression unit is configured to be coupled to a sidewall of an enclosure.

A mobile compressed foam firefighting unit comprising a mixing chamber connected at the outlet to the foam feeder, and the following systems connected to the mixing chamber inlet: a water supply system comprising a water pump and a water pump drive, a foam concentrate supply system comprising a foam pump and a foam pump drive, and an air supply system comprising an air compressor and an air pump drive. The system includes a drive motor, and drives of the air compressor and the foam pump comprise variable hydraulic transmissions kinetically connected to the drive motor, and the system is equipped with a water flow meter, a throttle valve with an electric drive and a check valve, and an electronic control unit of the throttle valve installed in the water supply pipe between the water pump and the mixing chamber.

An energy storage system includes at least one battery rack including at least two battery modules, a container in which the battery rack is received, an air conditioner including an outside heat exchanger configured to cool a heat exchanger medium having a temperature rise in the container, and a circulation path configured to allow the heat exchanger medium to circulate between the container and the outside heat exchanger, a fire extinguishing unit including a fire extinguishing agent tank configured to detect a temperature of the at least one battery module that is equal to or higher than a predetermined temperature or smoke that is generated in the at least one battery module and feed the fire extinguishing agent to the battery module, and an air conditioner management unit configured to spray the fire extinguishing agent in the fire extinguishing agent tank onto an outer surface of the outside heat exchanger.
