A fire exposure protection sprinkler assembly provides fire exposure protection for one or more windows and includes a fire exposure protection sprinkler, a sealing assembly configured to unseal in response to a fire such that fire exposure protection fluid may flow from the fire exposure protection sprinkler, and a housing having a pair of legs, with each of the legs having an aperture. The assembly also includes a deflection assembly configured to extend from the housing due to gravity and activation of a cover plate, with a deflector configured to disperse the fire exposure protection fluid over the one or more windows so as to wet the one or more windows.

Techniques and safety devices are described for extinguishing fires within an inventory management system. A plurality of fire extinguishing devices for a plurality of containers in an inventory management system is monitored. Upon determining that a fire condition is occurring within the inventory management system, a positional information data store is queried to determine a current position of a first container within the inventory management system. Two or more containers within the inventory management system that are in close proximity to the first container are identified and one or more wireless signals are transmitted to two or more fire extinguishing devices of the plurality of fire extinguishing devices that are contained within the two or more containers, to activate the two or more first extinguishing devices. The plurality of containers is scanned using an infrared scanning device to determine whether all fire conditions within the inventory management system are extinguished.

A wall-mountable spray head unit for delivering a fire suppressant liquid is disclosed. The spray head unit includes a rotatable spray head assembly having a spray manifold rotatable about a first axis, and a spray nozzle supported by the spray manifold and orientated to deliver fire-suppressant material radially in a plane defined by the first axis and a second axis which is perpendicular to the first axis. The spray head unit also includes one or more fire-locating sensors including a visible-light camera, a microphone, or both.

A cartridge with a status indicator, a fire suppression system for incorporating the same, and a method of inspecting whether a fire suppression system is capable of being actuated are provided. The status indicator is connected to the body of the cartridge. The status indicator defines a first state and a second state. The status indicator undergoes a change from the first state to the second state when exposed to a physical change. The physical change may include at least one of a decrease in temperature beyond a threshold, an increase in relative humidity beyond a threshold, and a threshold differential temperature change. The physical change is caused by the discharge of the cartridge. When installed within a fire suppression system, the status indicator enables the visual inspection of whether the fire suppression system is capable of being actuated.

A corrosion monitoring system of a fire protection system includes at least one first antenna and a processing circuit. The at least one first antenna receives a radio frequency (RF) signal through an internal volume of at least one pipe of the fire protection system. The processing circuit includes one or more processors and memory including computer-readable instructions that when executed by the one or more processors, cause the one or more processors to determine a signature of the RF signal, compare the signature to an expected signature, and determine, based on the comparison, that corrosion in the at least one pipe has occurred.

A fire-suppression system includes an aviation vehicle and a fluid transport and delivery system. The fluid transport and delivery system is coupled to a vehicle frame of the aviation vehicle and is located within a cabin of the vehicle frame. The fluid transport and delivery system includes a tank having an exit aperture formed in a bottom wall of the tank, a plug aligned with the exit aperture of the tank, and a plug actuator configured to move the plug along an axis from an open position, in which the fluid stored in the tank passes around the plug and through the exit aperture, to a closed position, in which fluid is blocked from exiting through the exit aperture.
