A fire suppression system specially adapted for placement in a warehouse having a ceiling deck supported by exposed metallic structural support members. The fire suppression system includes a supply line that feeds water to an array of self-activating sprinkler heads. The sprinkler heads are located near or below the exposed metallic structural support members to achieve many performance-enhancing and cost-saving benefits. One or more sprinkler heads may include respective heat collectors designed to capture upwardly rising heat plumes. The heat collectors agitate the collected air to improve activation responsiveness. In some embodiments, the heat collectors include vent-like aspiration ports coupled with exterior louvers to scavenge heat from a ceiling jet.

A fire protection system includes a dry pipe system and a controlled discharge gas vent. The dry pipe system and controlled discharge gas vent operate using a breathing cycle to displace oxygen and/or water vapor from within the piping network of the dry pipe system. The controlled gas discharge vent allows displacement of pressurized air with nitrogen, for example, using manual or automated processes that can employ one or more sensors. Corrosion resulting from oxygen, water, and/or microbial growth is reduced or nearly eliminated.

A connector includes a first member defining a first opening; a second member defining a second opening; and a third member defining a third opening, the first opening, the second opening, and the third opening being centrally connected to define a cavity within the connector. A method for draining a sprinkler assembly includes removing a plug from a third opening of a connector of the sprinkler assembly, a sprinkler body of the sprinkler assembly connected to a first opening of the connector, a flexible conduit of the sprinkler assembly connected to a second opening of the connector; and draining a fluid from the connector and the flexible conduit through the third opening.

Fire suppression systems (10) for vehicles and industrial applications including arrangements of an input bus (24) and output bus (26) coupled to a centralized controller (20) to provide for automatic and manual detection of a fire (H) and manual and automatic system actuation in response to the fire. The arrangements further provide for system information regarding the status and operation of the system components. Additionally, the arrangement of system components provide for expandability and programmability to configure the system for the protection of multiple and variable hazards (H) using customized or programmed detection and/or actuation. The systems include configured connectors (25) and colour coded schemes to facilitate system installation.

In a nitrogen generator, multiple, concurrent gas pressure monitors constantly and simultaneously monitor gas pressures at key points in the nitrogen generation process, and a controller generates an alarm when the pressure at any point falls below a respective predetermined pressure level, and remains there for longer than a respective predetermined duration. In some embodiments, a run time of the nitrogen separation unit is additionally monitored. Additionally, in some embodiments, if the output pressure of nitrogen gas falls below a predetermined pressure level, a bypass route is activated to route compressed air directly to the output, thus sacrificing nitrogen gas purity but maintaining required minimum pressure for downstream systems
