Abstract: A ceiling ventilation hood and fire protection system includes a ceiling ventilation hood, the ceiling ventilation hood defining an upper plane and a lower plane with a filter disposed between the upper and lower planes, and at least two nozzles each having an outlet defining a discharge axis with the outlet disposed in the ceiling ventilation hood between the upper and lower planes to provide overlapping protection of a hazard zone. Each of the nozzles define a spray pattern to effectively address a fire within the hazard zone independent of airflow through the filter. The outlets of the at least two nozzles are positioned at least 54 inches above the hazard zone.

Abstract: A global fire suppression system includes a primary controller, and a plurality of local fire suppression systems. Each local fire suppression system includes a secondary controller coupled to the primary controller, at least one detection device coupled to the secondary controller, and at least one release device coupled to the secondary controller. Each secondary controller is configured to act as the primary controller should the local fire suppression system become isolated from the primary controller.

Abstract: Preferred systems and methods for ceiling ventilation hood fire protection are provided in which fire protection nozzles are installed within a ventilation hood (12) to address a fire in a hazard zone (HAZ) below the ventilation hood. The fire protection nozzles (20) are disposed proximate the ventilation filters (18) or ports within the ceiling ventilation hood to provide overlapping protection of the hazard zone independent of airflow through the hood.

Abstract: An automatic fire suppressing system is preferably provided onboard a vehicle and is supplied with one or more fire suppressing agents that are discharged in response to detecting a fire threat. Preferred embodiments include high-speed valves for discharging the fire suppressing agent(s), optical detectors for detecting and evaluating fire threat conditions, and modules for monitoring and controlling the automatic fire suppressing system.

Abstract: Fire protection system and methods for a cooking appliance located in a hazard zone includes a firefighting supply and one or more nozzles coupled to the supply for generating a spray pattern to address a fire in the hazard zone. The system includes a preferred nozzle location zone to locate the nozzle outlet at a nozzle height from the hazard zone. The nozzle location zone has a first linear edge and a second linear edge spaced from the first linear edge with each of the first and second linear edges being parallel to the hazard zone. The second linear edge defines a minimum nozzle height and the first linear edge defines a maximum nozzle height. The maximum nozzle height ranges from sixty inches (60 in.) to sixty-eight inches (68 in.) from the hazard.

Abstract: A valve for a fire extinguishing system includes a housing, a flow control apparatus, an actuator apparatus, and a manual override apparatus. The flow control apparatus is disposed in a cavity to prevent or permit flow of the fire extinguishing agent from an ingress aperture to an egress aperture of the housing. The flow control apparatus includes a burst disk clamped between the first and second annular faces and an annular spool axially movable along the longitudinal axis relative to the housing. The actuator apparatus includes a bearing sleeve angularly movable around a longitudinal axis relative to the housing and a latch element operably coupling the bearing sleeve and the annular spool. The manual override apparatus includes a cam operably coupled to the bearing sleeve.
