Systems and methods for fire suppression systems are disclosed. The methods may include operating the fire suppression system in a first configuration. The methods may further include shifting the fire suppression system from the first configuration to a second configuration in which pumping of foam concentrate to the upstream side of the water pump is stopped and in which foam concentrate is pumped to a downstream side of the water pump. The fire suppression system may be operated in the second configuration whereby a portion of the water pumped from the water pump is combined with foam concentrate to supply a first one of the plurality of manifolds, and another portion of the water pumped from the water pump is provided without foam concentrate to supply a second one of the plurality of manifolds.

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.

A fire detection and/or extinguishing control station for actuating two extinguishing agent supply devices using a control unit. After actuating a first extinguishing agent supply device (17) upon detection of a first fire signal at time (t.sub.1), the control station is additionally equipped to actuate a second extinguishing agent supply device (18) upon detection of a second fire signal at time (t.sub.2) if the control station has checked whether the time (t.sub.2) fulfills the inequality (t.sub.1+t.sub.c)<t.sub.2<(t.sub.1+t.sub.b), where (t.sub.c) represents a discharge time of the complete or partial discharge of at least one extinguishing agent container (1) of the first extinguishing agent supply device (17), (t.sub.k) represents a check time connected to the discharge time (t.sub.c), and (t.sub.b) represents a monitoring time period, and the monitoring time period (t.sub.b) is the sum of the discharge time (t.sub.c) and the check time (t.sub.k) beginning at time (t.sub.1).

An integrated operator interface for a fire suppression system is provided. The fire suppression system includes an engine, a water source, a water pump, a foam system and a compressed air system. The integrated operator interface includes a control panel including a plurality of one-touch activation controls. Each one-touch activation control is configured to cause the output of a predetermined fire suppression fluid from the fire suppression system and cause a predetermined increase in engine speed resulting in an associated increase in water pump pressure. The predetermined fire suppression fluid comprising a predetermined flow of water, a predetermined type of foamant, a predetermined concentration of the predetermined type of foamant, and a predetermined flow of compressed air.

A self-locking sprinkler is disclosed. The self-locking sprinkler includes an outer body having a receiving portion positioned within an outer wall, where a fluid path is formed between the receiving portion and the outer wall, and a sprinkler diffusor threadedly connected to the receiving portion. The outer wall has an outer threaded surface configured to screw into a fluid dispensing system. The receiving portion has an inner threaded surface defining a central aperture. The sprinkler diffusor includes a blade configured to dispense the fluid, and a threaded post extending perpendicularly from the blade, where the threaded post threadably mates with the inner threaded surface. The self-locking sprinkler also includes a self-locking mechanism configured to exert a turning momentum in opposition to a rotation of the blade.

A fire truck comprising a body, a wheel, and a fire suppression system supported by the body is disclosed. The fire suppression system includes a valving arrangement with a valve that is shiftable between a first position corresponding with a first configuration of the fire suppression system and a second position corresponding with a second configuration of the fire suppression system. In the first configuration, foam concentrate flows through a first foam line, water flows through a water supply line and mixes with the foam concentrate, and a foam concentrate-water mixture is passed into a first manifold through a foam-concentrate water mixture line. In the second configuration, water flows through both the first water line and a second water line, foam flows through the second foam line, a foam concentrate-water mixture is passed into the first manifold, and pure water is passed into a second manifold.

Fire extinguishing systems and methods, such as for combating compartment fires, can include or use wet and dry agents such as water droplets and aerosol-based particulate extinguisher agents. In an example, an extinguishing system includes a centralized extinguishing controller that can selectively provide the wet and dry agents to a compartment or environment. In other examples, dedicated dispenser systems separately, but optionally concurrently, provide water and aerosol-based agents to combat a compartment fire.

A device for suppressing or extinguishing electrical fires in an electrical box, in particular an open top electrical box isolating a transformer. The device is based upon a bulk package receptacle placed within the electrical box having a liner filled with a fire suppressant material capable of suffocating or eliminating a fire. Should a fire occur the bulk package receptacle bursts at the point of combustion and the fire suppression properties of the fire suppressant would immediately be dispensed over the electrical material and extinguish any associated fire. In the preferred embodiment the bag consumes about 90% of the airspace and contained sufficient fluid volume to contain within the container. The admixture further encapsulates noxious and toxic gases associated with electrical fires.

An energy storage system according to an aspect of the present disclosure includes a control container having a battery system controller (BSC), a master controller connected to the BSC through a first communication line, and a bank battery management system (BBMS) connected to the BSC through a second communication line; and a battery container including a slave controller connected to the master controller through the first communication line, and a rack battery management system (RBMS) connected to the BBMS through the second communication line and for monitoring a state of a corresponding battery rack.
