An aircraft fire suppression system includes a container filled with gases in both a liquefied state and a compressed gas state. The container includes a first tube positioned in the liquefied gas section configured to expel a regulated amount of liquefied gas into the fire suppression system. The container also includes a second tube positioned in the compressed gas section configured to expel a regulated amount of compressed gas into the fire suppression system.

An extinguishing device for an electrical unit on an aircraft cabin monument or in an aircraft structure cavity, a combination of a holder and an extinguishing device and systems formed by extinguishing devices and a control unit and by combinations of an extinguishing device and a holder and a control unit. The extinguishing device has a base element for a holder. An extinguishing agent container has a casing and holds an extinguishing agent. A triggering device is connected to the extinguishing agent container to act in response to receiving a triggering signal wherein an extinguishing agent is released into the extinguishing device surrounding area. A data transmission device has a data store with an identifier unique to the extinguishing device and connected to the triggering device, the data transmission device for sending a warning signal via a network to a control unit in response to the triggering device receiving the triggering signal.

A fire suppression system has a tank unit (40, 42, 44, 46). A tank body has a first port and an interior for storing at least one of fire suppressant and driver gas. A discharge assembly is mounted to the first port and has a discharge valve (50, 52) and a first monitoring switch or sensor (230 240) having a normally closed output (532) and a normally open output (534). A first monitoring system (100) is coupled to one of the normally closed output and the normally open output. A second monitoring system (340) is coupled to the other of the normally closed output and the normally open output.

Methods, devices, and systems for fire control panel interface generation are described herein. In some examples, one or more embodiments include a fire control panel comprising a memory and a processor to execute instructions stored in the memory to determine, from a plurality of geographic regions, a geographic region for the control panel, determine a set of standards corresponding to the determined geographic region, and generate a fire control panel interface using the determined set of standards, and a user interface to display the fire control panel interface.

A system for storing a hazardous product including a housing unit defining a product opening and a product door coupled to the housing unit adjacent to the product opening, wherein the product door is configured to form a seal with the housing unit about the product opening in response to a thermal event.

A fire and smoke actuator includes a temperature sensor for sensing an operating temperature of the fire and smoke actuator, a drive motor, an actuator output for coupling to the damper in order to move the damper between the open position and the closed position and a drivetrain that is operably coupled between the drive motor and the actuator output. The drive motor, when activated, is configured to actuate the actuator output, via the drivetrain, to move the damper between the open position and the closed position. A drive circuit is operably coupled to the drive motor and the temperature sensor and is configured to activate the drive motor to move the damper between the open position and the closed position at a non-zero speed that is based, at least in part, on the operating temperature sensed by the temperature sensor.

An extinguishing-agent discharge device includes a casing having a guide channel for an extinguishing agent, a metallic handle, a hose connection, an adjustment means for regulating an extinguishing-agent supply using a manual control unit and a discharge nozzle. A measuring-current transformer generates a current signal proportional to the electric current flowing in the extinguishing agent; an insulator section divides the casing into a discharge area having the discharge nozzle and an inlet area having the manual control unit, the measuring-current transformer disposed in the insulator section; a first electrode disposed in the discharge area in the extinguishing-agent flow and serves for detecting an extinguishing-agent potential; a second electrode disposed at the handle for detecting a ground potential in the inlet area; and a controller for evaluating the current signal for a potential difference occurring between the extinguishing-agent and ground and having a drive element acting on the adjustment means.

A valve assembly for a firefighting bucket includes a base plate having an opening, a valve body configured to seal the opening of the base plate, and a linear actuator coupled to the valve body and configured to displace the valve body. Valve control systems direct the release of firefighting material through the valve assembly at a constant flow rate. The valve body may have a chamfered, tapered, or rounded surface to restrain the head pressure of the firefighting material.

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.

An improved system detects an environmental anomaly in a shipping container and initiates a mediation response through a generated layered alert notification. The system includes sensor-based ID nodes associated with packages within the container, and a command node mounted to the container communicating with the ID nodes and an external transceiver on a vehicle transporting the container. The command node is programmed to detect sensor data from the ID nodes; compare the sensor data to package environmental thresholds in context data related to each ID node; detect the environmental anomaly when the comparison indicates an environmental condition for at least one package exceeds its environmental threshold; responsively generate a layered alert notification identifying a mediation recipient and mediation action, and establishing a mediation response priority based upon the comparison; and transmit the layered alert notification to the transceiver unit to initiate a mediation response related to the mediation action.
