It is useful to understand how objects within this distribution area can alter the throw and disrupt the ability of the sprinkler Technical Questions? When an obstruction is more than 4 feet wide, extended coverage sprinklers cannot be arranged to throw water around the obstacle, no matter how far down the obstruction is. November 2019 The maximum distance permitted between sprinklers shall comply with Table 11.2.2.1.2. The problem at that time was that Table 4-9.5.1.2 for extended coverage sidewall sprinklers did not have a similar allowance for obstructions closer to the sprinkler. Flanking the obstruction will not solve the problem either. If the obstruction does not exceed 4 ft wide, standard pendant- and upright-spray sprinklers shall be permitted to be spaced on opposite sides of such obstructions, provided the distance from the centerline of the obstruction to the sprinklers does not exceed one-half of the allowable distance permitted between sprinklers. Merely divide the area of the room by the number of sprinklers to get the area of coverage for each sprinkler. There should be some plan set forth though to prevent sprinklers from being replaced with standard coverage down the road. In some circumstances, standard distribution sprinkler heads will not provide enough coverage. Standard sprinklers are just that: the standard when it comes to installing sprinklers.

Where the distance between the upper ceiling and the sprinkler deflector is less than or equal to 36 in. Where walls are angled or irregular, the maximum horizontal distance between a sprinkler and any point of floor area protected by that sprinkler shall not exceed 0.75 times the allowable distance permitted between sprinklers. For most obstructions, sprinkler designers turn to a couple of different versions of a pretty handy rule. Listing dimensions shall be even-numbered square protection areas as shown in Table 11.2.2.1.2. (550 mm) below the ceiling/roof deck, Installed with the deflectors at or above the bottom of noncombustible structural member to a maximum of 22 in. October 2016 (100 mm) from a wall unless listed for distances less than 4 in. Design Documents 2. Table 11.2.5.1.2 (reproduced below) allows the user to determine how high above the bottom of the obstruction to place a sprinkler based on the horizontal distance between the sprinkler and the obstruction. To ensure the lower sprinklers operate as intended, the heads installed under open grating or round ducts should have the same kind of water shield (baffle) typically found on intermediate-level in-rack sprinklers (11.2.5.3.4-5). It says that the maximum distance from the sprinkler deflector to the obstruction is the smaller of four times the largest dimension of the obstruction or 36 inches. In the unobstructed light hazard spaces covered in Table 10.2.4.2.1(a), the maximum area one sprinkler can protect is 225 ft. 2 (20 m 2): (1.7 m) to less than 6 ft (1.8 m), 6 ft (1.8 m) to less than 6 ft 6 in. I'd suggest using concealed type sprinklers the cover plates look the same on each. Ensure response type matches.

Locate these points by drawing a perpen-dicular line from each part-circle head, across the area, to the . Other sprinklers have to be determined by taking the density times the protection area per sprinkler in Section 8.5.2.1. In this article, weve explained how NFPA 13 directs sprinkler system designers to space extended coverage fire sprinklers when obstructions are present. In this case, an adequate spray pattern will develop without placing sprinklers beneath the obstruction (11.2.5.3.2, 11.3.6.3). (2 m), 6 ft 6 in. NFPA 220 A practice I like to do is making the EC sprinklers a different orifice if possible. I cannot think of a code section that states you cannot mix standard and extended coverage sprinklers. If you continue to use this site we will assume that you are happy with it. First, if the obstruction is more than 18 inches below the deflector of the sprinkler, you should not use the four-times rule. Head-to-Head coverage applies to both sprays and rotors.
