The jurisdiction has complained that the inspection forms are lacking information and details. Is this the intent of NFPA 25? We have reviewed NFPA 25, edition as the applicable standard.
Our informal interpretation is that NFPA 25 does not require that NFPA 13 deficiencies be found or noted during an inspection of a fire sprinkler system or that specific forms have to be used.
The intent of NFPA 25 is only to address maintenance issues with an overall objective of ensuring that the system is mechanically operational. When an inspection is conducted in accordance with NFPA 25, it is assumed that the installation met the minimum requirements of the installation standard when it was installed. As stated in Section 1. The intent of the scope statement is to relieve the inspector of the burden of continually re-verifying the design and installation of the system.
The scope statement basically means that the function of the inspector is to look for signs of normal wear and tear or aging of the system and components, not to re-verify acceptance criteria. Thus adding a section to the report that the system is correct for the occupancy or hazards may expose you to liability issues as the company completing NFPA 25 inspections.
However, when NFPA 13 deficiencies exists and are known, it may be prudent for an inspector to inform the owner by separate correspondence. Noting these items separately shows due diligence and may ease concerns of liability for the inspecting contractor.
The problem with this is noted in the handbook commentary that the inspector performing the work is not necessarily trained to make this evaluation, nor is it cost effective for such an evaluation to take place each year. It only requires that the system be capable of operating properly.
A copy of the inspection report shall be provided to the owner at the completion of each inspection performed. Number 8 indicates that the inspection report shall include a detailed explanation of every deficiency, and indicate if the inspection is a weekly, monthly, quarterly or annual inspection. NFPA 25 does not require any specific forms or minimum information that is to be included on report forms. This is at the discretion of the contractor or owner.
Section 4. The annex A. These forms are not required to be used, especially with the increasing use of handheld inspection reporting software available by several vendors. All Rights Reserved.Hi Laura:. With a little more effort, I will answer your questions as directly as possible.
Does any heat-tracing placed on the service main below grade and above grade outside the building have to be listed for below grade use? Does any of it have to be listed for use on fire protection piping? The edition of NFPA 13 Standard for the Installation of Sprinkler Systems allows Listed electrical heat tracing to freeze protect fire suppression systems including supply lines, standpipes and branch lines containing sprinklers.
The system covered in this manual includes supply lines, stand pipes, branch lines and sprinkler heads. XL-Trace systems are also UL and ULC Listed for freeze-protecting sprinkler supply lines, standpipes up to 20 inches in diameter and branch lines not containing sprinklers. If we use cable listed for commercial piping, and listed for underground use where it's underground, are we meeting the intent of the code?
The heat trace is a listed system of integrated accessories, controllers, cables, design and installation instructions, and fire alarm panel interconnects for supervision for the freeze protection of fire sprinkler supply pipes, standpipes, and branch lines. Since the only reference to "positive confirmation that the circuit is energized" is under protection of branch lines, would this be required for the service main line?
I would say yes the listed heat trace system controllers must be interconnected with the fire alarm system for supervision. IEEE Yes there is a product form Tyco.
Respectfully, Milt Werner.It revises the edition of the same standard. NFPA helps users meet important fire safety concerns. As discussed in a past post about NFPA 13Rsprinkler systems are crucial in safeguarding against fire. In NFPAguidelines for the installation and design of automatic fire sprinkler systems and exposure protection systems can be found.
It is important to remember that water mist fire protection systems do not qualify as fire sprinkler systems. The information covered in NFPA presumes that the automatic sprinkler systems are designed to protect against a single fire originating within the building.
With the help of standardized design, installation, and testing guidelines, NFPA offers protection for life and property from fire. Installation and design of sprinkler systems should come from knowledgeable personnel. NFPA applies to the following:.
903.3.1.1 NFPA 13 Sprinkler Systems
A building considered to be protected by an automatic fire sprinkler system should have sprinklers in all areas unless otherwise designated in NFPA The latest edition of NFPA has some changes, including:.
How many sprinkler provide a podium area is 50x 20 sqr. Ram area is sprinkler require or not. Your email address will not be published. This site uses Akismet to reduce spam. Learn how your comment data is processed. Installation of private fire service mains included. The latest edition of NFPA has some changes, including: Underground piping, water supplies, and hazard classification are now located at the beginning of the standard.
Chapter 8 was separated into numerous chapters. Chapters on storage have been restructured by sprinkler technology and address ceiling-only design. Revised Chapter 25 to include all the guidelines for in-rack sprinklers. Guidelines on both vertical pipe chases and electrical equipment rooms where sprinklers can be omitted have been clarified.
Added new beam rules for residential sprinklers. Added new features to help users locate guidelines and recognize technical changes. A roadmap that compares the section numbers of the two editions has been compiled and can be found after the index.

The following are noted as light hazard occupancies: offices, churches, schools, museums, auditoriums, library seating areas, restaurant seating areas, and unused attics. The maximum sprinkler spacing protection area for these is noted in Table 8. Usually, the maximum limit is square feet for light hazard on a hydraulically calculated system.
However, when exposed construction is combustible, with structural members spaced less than 3 ft.
Ordinary hazard Group 1 occupancies include laundries, restaurant service areas, and automobile parking garages. Ordinary hazard Group 2 occupancies include the aforementioned dry cleaners, automobile repair and services areas, auditorium stages, woodworking plants, post offices, and stack room areas of libraries. Standard sprinklers protecting all ordinary hazard occupancies shall not cover an excess of square feet per head Table 8.
Extra hazard occupancy examples include printing plants, paint and varnish dipping operations, plywood manufacturing, solvent cleaning, and plastics processing.
Maximum sprinkler spacing for these occupancies is limited to square feet. However, where the required design density is less than 0. It should be noted that commercial insurance carriers and consultants develop their own literature containing more extensive listings of occupancy examples and classifications than does the NFPA 13 standard, data which often comes in handy when making an occupancy classification determination.
When hydraulically calculating a light hazard sprinkler system, the design density utilized is typically 0.
Suppose that the sprinklers are spaced 14 ft. Our square foot coverage then, is 12 x 14 square feet. Q in gpm is determined by multiplying the density by the square foot coverage.
If the design density is 0. If our area of operation remains square feet, our design density will change to 0. Everything changes when extended-coverage sprinklers are employed. If we choose to install Tyco EC pendent sprinklers, the data sheets dictate that our end-sprinkler must discharge a minimum of 33 gpm at 8.
This means that our design density Q divided by the square foot coverage is still 0. The K-factor of this particular sprinkler is Topics: new yorkSprinkler designFire sprinkler systemFire protection engineeringsprinkler system installationlocal law 26Fire protection.
NFPA 13 is the industry standard on all matters related with sprinkler systems in the USA, and the first version was published over a century ago in It is important to note, however, that state and municipal authorities often introduce additional requirements. The NFPA 13 standard is nearly pages long, and very detailed in requirements and specifications. This article will provide an overview of the main points covered, but is by no means a substitute for the whole document.
Local Law 26 of makes fire sprinklers mandatory for all business occupancies where the building is at least feet tall. Since these projects can be time-consuming and capital-intensive in large buildings, the best advice we can give you is to start as soon as possible and with the assistance of qualified engineering consultants.
Newer editions of the NFPA 13 are not retroactive in most cases, which means you are not required to upgrade existing installations that were compliant at the time of installation.
If any specific requirement is retroactive, it is state clearly in the current version of NFPA Since fire sprinkler design involves plenty of technical concepts, the NFPA 13 dedicates its Chapter 3 to defining key terms that are used throughout the document. General requirements apply for all sprinkler systems regardless of the type of building or specific configuration, unless there is a direct exception in the code.
If a building uses fire sprinklers, NFPA 13 demands full coverage for the entire property unless the standard indicates clearly that a specific building area is optional. The NFPA 13 standard classifies occupancies by hazard level. It is important to note that this only applies for fire sprinkler systems, and is not a general classification.
Group 1: Low combustibility, moderate amount of combustible materials, stockpiles are not taller than 8 feet, and moderate heat release is expected from a fire. Group 2: The combustibility and amount of contents ranges from moderate to high. Contents with a moderate heat release are not stacked taller than 12 feet, and contents with a high heat release are not stacked taller than 8 feet. Group 1: The combustibility and amount of contents is very high, and there are compounds like dust or lint present, which can accelerate a fire if it occurs.
The rate of heat release from a fire is high, but combustible and flammable liquids are only present in small amounts or not present at all. Group 2: Moderate to large amounts of flammable or combustible liquids.
NFPA 13 requirement for "listed" heat-tracing systems
Also includes occupancies with ample shielding of combustibles. The classification is determined based on both the materials stored and the containers used boxes, pallets, crates, etc.
The core content of NFPA 13 is a description of all components used in automatic sprinkler systems, and a description of their correct installation procedure and mechanical support requirements. The standard establishes the requirements for all system components depending on their material and type.
NFPA 13 provides both general requirements and application-specific requirements. The NFPA 13 standard provides detailed requirements for each sprinkler system type.This form only contains certain aspects of the standard. It does not contain all of the JPR's as defined in the standard. Training Officer does not accept any liability for the use or misuse of this form. It is being published strictly as a guide sample to assist other departments on creating their own document that will work for their organization.
