NFPA 13 Seismic Bracing Requirements: Cable Sway Braces
https://blog.qrfs.com/320-nfpa-13-seismic-bracing-requirements/
NFPA 13 gives requirements for the placement of lateral braces and longitudinal braces on main lines, for the bracing of changes of direction of main lines, for the bracing of risers, and for the bracing of seismic separation assemblies ( see our article on flexible design for more information on these elements ).
Introduction to Seismic Protection for Sprinkler Systems
https://www.nfpa.org/News-and-Research/Publications-and-media/Blogs-Landing-Page/NFPA-Today/Blog-Posts/2021/03/19/Introduction-to-Seismic-Protection-for-Sprinkler-Systems
A sprinkler system installed in a building that is subject to seismic activity may require seismic bracing by the local or state building code . If required, Chapter 18 of NFPA 13 outlines requirements for the seismic bracing, which includes bracing, flexible connections, pipe clearance to structural members, pipe restraint, and restrictions on the types of hangers and …
Seismic Bracing and Calculations
https://www.kamal-mech-engr.com/seismic-bracing-calculations
This technique is known as seismic bracing, or sway bracing. NFPA 13 requires seismic bracing for fire sprinkler risers, main lines, and branch lines 2.5 inches or larger. Pipe smaller than these areas is generally more flexible and requires only vertical restraint rather than bracing.

https://www.eng-tips.com/viewthread.cfm?qid=232816
You must follow NFPA 13 rules for 13R installations. You will use the Ss (0.2) spectral accelleration value, and obtain it from the USGS web site based on latitude and longitude coordinates of the site. As far as the specifics of the seismic bracing referred to in IBC 2006, you may have missed it, but the reference document is ASCE 7, 2005 edition.
Seismic Restraint of Sprinkler Systems – NFPA-13 versus FM …
https://risklogic.com/seismic-restraint-of-sprinkler-systems-nfpa-13-versus-fm-global-standards/
FM Global specifies seismic bracing be provided when located in 50-year through 500-year earthquake zones, as shown on the maps in FM Global Data Sheet 1-2, Earthquakes. NFPA-13 allows the use of tension-only (i.e. – wire/cable type) braces, where FM only allows the use of tension-only bracing for end of branch line restraint.
NFPA 13 Standard for the Installation of Sprinkler …
https://www.nfpa.org/assets/files/AboutTheCodes/13/TIA13-02-1.pdf
9.3.5.3.1* Lateral sway bracing shall be provided on all feed and cross mains regardless of size and all branch lines and other piping with a diameter of 2½ in. (63.5 mm) and larger. Lateral brace assemblies in straight runs of pipe shall capable of resisting the anticipated seismic loads and spaced to a maximum interval not exceeding 40 ft (12.2
How to Determine if Sprinklers Require Seismic? - MeyerFire

Seismic bracing has roots in NFPA 13. As is the case between a “code” and a “standard”, however, NFPA 13 as a standard only tells us how to design and install the system. Code tells us when and where systems and components are required.

https://www.eng-tips.com/viewthread.cfm?qid=345093
Seismic Bracing. PRinspector (Military) (OP) 17 May 13 13:00. Ok, once again I'm looking from information about seismic bracing. I was walking a projejet the other day and I came across two things that did not look right to me. So I got back to the office and started to search NFPA 13 chapter 9 to see if the seismic installation is IAW to code ...
Chapter 9 Hanging, Bracing, and Restraint of System Piping
https://up.codes/viewer/colorado/nfpa-13-2013/chapter/9/hanging-bracing-and-restraint-of-system-piping
The system piping shall be braced to resist both lateral and longitudinal horizontal seismic loads and to prevent vertical motion resulting from seismic loads. 9.3.5.1.2 The structural components to which bracing is attached shall be determined to …
