Abstract: A fire protection sprinkler system and method includes a sprinkler which, in use, is operatively connected to a supply pipe. The sprinkler includes a nipple. A frame extends from the nipple. A duct passes through the nipple and frame creating a flow path for a water jet exiting the supply pipe. A deflector is mounted to the frame at a location spaced from the nipple. A splitter is disposed in the water flow path between the supply pipe and the deflector. The splitter separates the water jet into two distinct sub-jets before the water contacts the deflector. The splitter directs the two separate water streams onto the deflector so that less pressure is required resulting in more economical system smaller pipe size, less labor, etc.

Abstract: A fire suppression system in which the water supply line is fitted with repeating arrays or groups of sprinkler heads. Each array is composed of at least two side-discharge sprinklers. The side-discharge sprinklers in each array are aimed so that their coverage areas point in opposite directions. Each side-discharge sprinkler includes a lateral heat shield. The lateral heat shield has a concave heat-concentering side that focuses radiant heat toward the sprinkler's trigger, and a convex heat-scattering side that disperses radiant heat away from the trigger. In some embodiments, the array can include one or more vertical-discharge sprinklers. The vertical-discharge sprinkler may include a heat collector to facilitate early activation of its trigger. The fire suppression system is advantageous in high-challenge applications like facilities where large quantities of combustible items are stored in close proximity, such as in warehouses and attics.

Abstract: A fire suppression system in which side-discharge fire sprinklers are fitted to opposite sides of a supply line and aimed so that their coverage areas point in opposite directions. The fire sprinklers are alternated on left and right-hand sides of the supply line, and are spaced apart at a consistent interval. Each fire sprinkler includes a deflector configured to disperse the outflow of water over a non-circular coverage area. When two supply lines are installed next to each other so that half of the sprinklers on one supply line point toward the other supply line, and vise versa, the fire sprinklers are staggered so that their respective coverage areas are interlaced in the intermediate space.

Abstract: 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.

Abstract: A fire suppression system in which the water supply line (108) is fitted with repeating arrays of sprinkler heads (102, 106). Each array is substantially identical and is composed of two side-discharge sprinklers (106) and one vertical-discharge sprinkler (102). The side-discharge sprinklers (106) in each array are aimed so that their coverage areas point in opposite directions. The trigger (109) for the vertical-discharge sprinkler (102) has a lower activation temperature (Tv) than the activation temperatures (Th) of the side-discharge sprinklers (106) so that the vertical-discharge sprinkler (102) will activate earlier than either of the side-discharge sprinklers (106). The vertical-discharge sprinkler (102) may include a heat collector (104) to facilitate early activation of its trigger (109). The fire suppression system and method harness the working power of working of multiple orientations of fire sprinklers to produce, in effect, a super fire sprinkler system and method.

Abstract: An open framework warehouse storage rack system for supporting articles on multi-tiered shelves within the wetting zone of an overhead fire sprinkler system. The storage rack system comprises one or more a longitudinally extending rack arrays. A falling water collection system is combined with some or all of the rack arrays. The falling water collection system includes any one of several water handling features that enhance the wetting of storage articles during a fire. One such feature is a scoop-like longitudinal water catcher that protrudes outwardly beyond the front and/or rear faces of the rack array. Another is a transverse intra-stanchion water diverter. Another is a transverse mid-span water diverter. Another is a gutter formed integrally in an uppermost beam. And another is a vertical flue catcher. The falling water collection system maximizes the amount of water that is applied directly to a fire inside the rack array.

Abstract: A fire sprinkler of the preferred embodiments includes a frame, a trigger, and a deflector. The frame defines a duct to exhaust the flow of a fire suppressing or extinguishing substance, and includes a fastener to fasten the frame to a supply line. The trigger blocks the flow of the fire suppressing or extinguishing substance through the duct during a first mode, and permits the flow of the fire suppressing or extinguishing substance during a second mode. The deflector redirects the flow of the fire suppressing or extinguishing substance into a coverage area. The deflector also at least partially shields the trigger from the dispersal of a fire suppressing or extinguishing substance from an adjacent fire sprinkler and prevents a failure of the trigger.
