A system is disclosed which is operable to supply fire suppressant material (6) and marker (7) to at least one spray head unit (2) for producing spray having a droplet size less than 1000 m. The system may be operable in two modes. The system may be operable in fire suppressing mode to supply fire suppressant material to the one or more spray heads and in marker deployment mode to supply fire suppressant material and marker to the one or more spray heads. In fire suppressing mode, the system supplies the fire suppressant material for a long period of time, for example, a few tens of minutes. In marker deployment mode the system supplies the fire suppressant material and marker to the spray heads for a short period of time, for example, a few tens of seconds.

A passive fire response system is configured to suppress a metallic fire. The system includes a reservoir containing an ionic liquid, at least one outlet in communication with the reservoir, a valve arranged between the reservoir and the outlet, a sensor configured to sense at least one of a hydrogen concentration and a temperature and/or heat, and a controller configured to open the valve and release the ionic liquid if an output from the sensor indicates that the at least one of the hydrogen concentration and the temperature equals or exceeds at least one of a threshold hydrogen concentration and a threshold temperature.

An under bed fluid storage and pumping assembly for fire prevention and protection, which may be utilized in disaster relief housing that includes a first sprinkler system, is disclosed herein. In an example, the under bed fluid storage and pumping assembly includes a tank comprising a housing cavity and the fluid pumping assembly disposed within the housing cavity. In some examples, the housing cavity is formed on a top surface of a riser that extends above a platform to support a bed. In other examples, the housing cavity is formed below an opening on the platform. The housing cavity may include an embedded pump, a suction tube with an isolation valve, a discharge manifold with an isolation valve, a system pressure gauge, a system test control valve (which may be plumped back to tank through tubing and/or fittings), a pressure activated on/off switch, or the like, or combinations thereof.

A method for extinguishing objects or appliances, in which, once a fire signal has been detected at point in time t1, a first device (17) providing an extinguishing agent is triggered, for discharging a liquid synthetic extinguishing agent (14), via a separating device (8), a common conveying pipe (9) and at least one nozzle (10), and, once a second fire signal has been detected at point in time t2, a second device (18) providing an extinguishing agent is triggered for discharging water (3) or a water-based extinguishing agent via the separating device (8), the common conveying pipe (9) and the at least one nozzle (10) for extinguishing. A system is also provided for extinguishing objects or appliances.

An embodiment of the present invention includes an advanced adjustable density misting delivery system (AMDS) for detecting and neutralizing a fire. The AMDS includes a bladder containing a fire suppressant material, a pump operatively connected to the bladder via a tube, and a nozzle operatively connected to the pump and the bladder via the tube. The AMDS also includes a controller electrically connected to the pump and a sensor in communication with the controller, where the sensor is configured to detect a parameter that indicates the presence of the fire. The controller is configured to transition the pump from a deactivated state to an activated state when the sensor detects the parameter, such that in the deactivated state the pump does not operate, and in the activated state the pump causes the fire suppressant to flow from the bladder, through the tube, and out the nozzle.

An exemplary fire suppression system includes a sprinkler nozzle. At least one conduit is connected to the nozzle for delivering a fire suppression fluid to the nozzle. The conduit and the nozzle establish a discharge path. A pneumatically driven pump is connected with the conduit for pumping fluid into the conduit. A gas source provides pressurized gas to the pump for driving the pump. The gas source also provides gas to the discharge path for achieving a desired discharge of the fluid from the nozzle.

An automated spray assembly for fire suppression includes a controller, a power module, a pump, a tank, a plurality of emitters and a plurality of sensors. The power module, the pump, the emitters and the sensors are operationally coupled to the controller. The tank, which is configured to store a fire suppressing liquid, and the emitters are fluidically coupled to the pump. The emitters are configured to spray the fire suppressing liquid on an exterior of a structure. The sensors are positioned proximate to the structure. The sensors are configured to detect a fire proximate to the structure and to signal the controller to motivate the pump to compel the fire suppressing liquid through the emitters to the exterior of the structure.

A fire suppression system according to various aspects of the present technology is configured to deliver a fire suppressant material in response to a detected fire condition in a transportable container. In one embodiment, the fire suppression system comprises a detection system adapted to generate a detection signal when exposed to a fire condition that triggers a deployment valve to release a fire suppressant material into the transportable container. The fire suppression system is also be configured to be selectively disarmed to prevent actuation of the deployment valve in the event of an inadvertent signal generated by the detection system.

A passive fire response system is configured to suppress a metallic fire. The system includes a reservoir containing an ionic liquid, at least one outlet in communication with the reservoir, a valve arranged between the reservoir and the outlet, a sensor configured to sense at least one of a hydrogen concentration and a temperature and/or heat, and a controller configured to open the valve and release the ionic liquid if an output from the sensor indicates that the at least one of the hydrogen concentration and the temperature equals or exceeds at least one of a threshold hydrogen concentration and a threshold temperature.

A fire fighting vehicle includes a chassis, an engine coupled to the chassis, a fluid tank configured to store a fluid, a fluid delivery system, and a controller. The fluid delivery system includes a first pump, a second pump, a low pressure discharge, a first high pressure discharge, and a second high pressure discharge. The first pump is coupled to the fluid tank and configured to pump the fluid therefrom at a first pressure. The second pump is positioned downstream of and coupled to the first pump in a serial arrangement. The controller is configured to selectively vary at least one of a speed, a power output, and a torque output of the engine and thereby provide the fluid to at least one of the first high pressure discharge and the second high pressure discharge at a target discharge pressure.
