Both models are concealed in an enclosed escutcheon plate with a flat cover. Maximum working pressure is psi. This separable two-piece design allows installation of the sprinklers and pressure testing of the fire protection system prior to installation of a suspended ceiling, or application of the finish coating to a fixed ceiling. It also permits the removal of suspended ceiling panels for access to building service equipment without having to first shut down the fire protection system and remove the sprinklers.

April 2, This new reader line delivers unparalleled performance, versatility and smarter, more connected access control.You must have a Professional Engineer design a sprinkler system to address your specific situation and to meet the codes applicable in your jurisdiction. There are two main criteria for the location of sprinkler heads. First, sprinklers must be located so they are within the hot-gas layer that develops near the ceiling during a fire because activation occurs when the sprinkler head reaches a certain temperature.
Second, they must be located so that the water that is discharged from the sprinkler is not disrupted or affected by construction elements such as beams, trusses, or soffits. The diagram below shows the water distribution for standard pendant and upright sprinkler fixtures.
It is useful to understand how objects within this distribution area can alter the throw and disrupt the ability of the sprinkler to extinguish a fire. This is a general depiction of sprinkler throw and should not be used to determine sprinkler spacing. Refer to the manufacturer data for specific throw data. Please note, that the throw of a sprinkler should not be used for sprinkler spacing - local codes determine spacing requirements.
According to NFPA 13 8. Therefore, building owners must ensure that all storage and objects in the room remain 18" below the sprinkler deflector as shown in the image below.
The table below shows sprinkler spacing requirements based on NFPA This table shall be used only as a tool for architects. Distance from Ceiling: minimum 1", maximum 12" for unobstructed construction. The minimum 1" is typical; however, concealed, recessed, and flush sprinklers may be mounted less than 1" from the ceiling and shall be installed based on their listing. In some circumstances, standard distribution sprinkler heads will not provide enough coverage. In these cases, extended coverage sprinkler heads can be installed to increase the spacing between heads.
Extended coverage sprinklers have a water distribution radius of a little over 10 feet, so they can be spaced approximately 20 feet apart. Bluebeam Tools and Templates Tool sets, hatches, line types, stamps, and templates for Bluebeam Revu.
Best Architecture Books Our list of the top reference books for architects - these are the ones we have on our shelf.This invention relates to fire prevention sprinklers for distributing a fire extinguishing liquid such as water in an environment which is subject to a fire hazard. Many conventional fire prevention sprinklers consist of a threaded sprinkler body connected to a water supply pipe to receive water under pressure and having a heat-responsive arrangement blocking a passage in the sprinkler body which is set to open the passage when the temperature in the vicinity of the sprinkler exceeds a selected value.
In order to distribute the water emerging from the sprinkler passage throughout the area to be protected, the sprinkler includes a deflector which is supported from the sprinkler body by arms so that water emerging from the sprinkler passage upon activation of the sprinkler impinges the deflector and is distributed thereby over the area to be protected.
Concealed sprinklers are usually covered by a cover plate which is substantially flush with a ceiling in which the sprinkler is mounted and have a deflector supported from the sprinkler body by sliding pins rather than fixed arms, permitting the deflector to be held in a retracted position above the ceiling and adjacent to the sprinkler body and to drop down to an extended position below the surface of the ceiling automatically and concurrently with the operation of the sprinkler after the cover has been released by a high temperature condition.
The Leininger et al. The Meyer et al. The Galaszewski U. The Fischer et al. Accordingly, it is an object of the present invention to provide an extended coverage concealed sprinkler which overcomes disadvantages of the prior art. Another object of the invention is to provide an extended coverage concealed sprinkler providing quick response coverage for light hazard occupancies at spacings up to eighteen feet and standard response coverage at spacings up to twenty feet.
These and other objects of the invention are attained by providing a sprinkler having a sprinkler body with an axial passage for water normally covered by a cap retained in position by a thermally responsive element and a deflector slidably supported by arms extending from the sprinkler body for motion between a retracted position adjacent to the sprinkler body and an extended position, in which the deflector has a substantially planar imperforate structure with opposed portions of the periphery of the deflector on opposite sides of a plane containing the arms being bent in the direction away from the sprinkler body passage.
In a preferred embodiment, the deflector is supported on pins which pass through the arms extending from the sprinkler body and has a central stream-splitting projection extending toward the sprinkler body passage. In addition, the bent portions at the periphery of the deflector on opposite sides of the arms extend away from the planar portion of the deflector at approximately the same angle that the arcuate surface of the projection intercepts the plane of the deflector.
Further objects and advantages of the invention will be apparent from a reading of the following description in conjunction with the accompanying drawings, in which:.
In the typical embodiment of the invention shown in FIG. Alternatively, a thermally responsive glass bulb may be used. The lever assembly 22 engages the cap 18 at one end and is supported at the opposite end by a screw 24 which extends through a boss 26 formed at the junction of two arms 28 and 30 extending parallel to the sprinkler axis from the sprinkler body A deflector 32, described in more detail hereinafter, is supported by two pins, 34 and 36, which are slidably received in corresponding guides 38 and 40 in the arms 28 and 30, respectively.
The pins 34 and 36 have enlarged heads 42 providing a close-fitting engagement with correspondingly shaped shoulders in the guides 38 and 40 thereby limiting downward motion of the deflector in the extended position while retaining the deflector 30 in an orientation substantially perpendicular to the sprinkler axis.
The concealed sprinkler 10 is arranged to be positioned in an opening 44 in a ceiling panel 46 and, in the illustrated embodiment, a cup-shaped cover support 48 is mounted on the sprinkler body 12 by screws 50 which are received in threaded openings in lateral projections 52 of the sprinkler body. The cup-shaped cover support 48 is formed with a thread 54 in a cylindrical extension A substantially planar cover member 58 is joined by solder joints to depending tabs 60 of a sleeve 62 which is received within the extension 56 and which has a plurality of helically arranged projections 64 positioned and shaped to engage the thread 54 of the extension 56 of the cover support 48, thereby permitting the cover 58 to be axially adjustably mounted with respect to the sprinkler body 12 by rotation of the sleeve 62 within the cover support A leaf spring 68 engages a circumferential shoulder 70 on the sleeve 62 and has a plurality of spring fingers 72 urging the rim of the cover 58 in the direction away from the sleeve member 62 as described for example in the Leininger et al.
Accordingly, when the ambient temperature in the vicinity of the sprinkler exceeds the melting temperature of the solder joints holding the cover 58 to the tabs 60, the depending fingers 72 of the leaf spring 70 force the cover 58 away from the sprinkler body and, when the elevated temperature exceeds the release temperature of the thermally responsive structure 22, the lever assembly comprising that structure is released, permitting the cap 18 to be forced away from the orifice 20 by the pressure of water in the passage At the same time, the deflector 32, which is no longer supported by the cover 58 and is subjected to water under pressure emerging from the orifice 20, drops below the level of the ceiling 46 until the enlarged portions 42 of the pins 34 and 36 are held in the guides 38 and 40 so that the deflector is retained in the extended position beneath the ceiling panel 46, enabling distribution of water from the orifice 20 over the area to be protected.
In order to provide the desired extended coverage of the sprinkler, the sprinkler deflector 32, as shown in FIGS. In a preferred embodiment, the diameter of the plate 80 which extends through the arcuate portions 82 is between about 1. As best seen in FIGS. In operation, when the thermally responsive element is activated at an elevated temperature, the lever assembly 22 supporting the cap 18 collapses, releasing the cap and permitting water passing through the orifice 20 to impinge on the deflector 32, causing the deflector to be moved away from the sprinkler body 12 until the enlarged portions 42 of the pins 34 and 36 engage corresponding shoulders in the portions 38 and Although the invention has been described herein with reference to specific embodiments, many modifications and variations therein will readily occur to those skilled in the art.
Accordingly all such variations and modifications are included within the intended scope of the invention. Effective date : Year of fee payment : 4.
Year of fee payment : 7. Year of fee payment : 8. Year of fee payment : A concealed extended coverage quick response sprinkler has a sprinkler body with an axial passage for water, a cap normally closing the axial passage, and a thermally responsive structure supported from a pair of frame arms retaining the cap in position.
