A method of checking a pressure of an agent cylinder that includes coupling a gauge assembly to an outlet of a gauge tool, the gauge assembly having a pressure gauge and a vent valve movable between an open position and a closed position. The method further includes moving the vent valve towards the closed position; attaching a fill adapter defining an inlet of the gauge tool to a valve port of an agent cylinder; and actuating a drive member of the gauge tool in a first direction to move a valve member of the gauge tool from a first position towards a second position to facilitate a fluid flow between the inlet and the outlet of the gauge tool.

A selector valve for a fire suppression system includes a pneumatic fluid inlet connecting to an inlet of a first pressure solenoid and an inlet of a second pressure solenoid. An inlet of a first vent solenoid in the selector valve is connected to an outlet of the first pressure solenoid, and an inlet of a second vent solenoid in the selector valve is connected to an outlet of the second pressure solenoid. A first selector valve outlet is connected to the outlet of the first pressure solenoid and a second selector valve outlet connected to the outlet of the second pressure solenoid.

Remote controllable selector valve configuration

A fire suppression nozzle can include a first fluid channel configured to be in fluid communication with a first fluid having a first flow velocity and a second fluid channel configured to be in fluid communication with a second fluid having a second flow velocity. A mixer can be disposed between the first fluid channel and the second fluid channel such that the mixer is configured to induce streamwise vorticity in at least the first fluid exiting first fluid channel to cause mixing of the first fluid and the second fluid to reduce a flow speed of a mixture of the first fluid and the second fluid.

Noise reducing fire suppression nozzles

A fire protection system and method for an enclosure includes an inert agent supply source configured to discharge an inert agent following a discharge of a primary agent in the enclosure, a gas detector configured to determine a gas concentration level in the enclosure, and a controller connected with the inert agent supply source and the gas detector and configured to regulate the discharge of the inert agent into the enclosure based at least partially upon the gas concentration level.
