Even with the comparatively small number of proposals offered this cycle, there were plenty of items of work for the committee. The committee had to contend with shortened sessions due to hurricanes in Florida and Texas, the two meeting destinations.

The committee was required to use several teleconferences to complete the proposal review. The committee must sift through these items to ensure a proper review is offered upon each proposal. Some of the proposals presented this cycle did afford just such a challenge to the committee.

Chapters 1 and 2 are virtually unchanged from the preceding edition. Chapter 1 is unchanged. Chapter 2 reference publications received the normal updates for the referenced publications. Throughout the new edition of NFPA 20, the text changes are highlighted by shaded areas and bullets for new sections, deletions, and new material.

The new marking system in this edition is a real improvement when researching or identifying the changes and additions made in the standard. These new products are included in addition to the previously approved variable speed pressure limiting and suction limiting controllers.

Refer to section 3. Clarifications are included to better identify the different variable speed options. One of the more interesting proposals received relates to remote distance monitoring for the periodic fire pump no-flow test. There are many devices available to allow development of a remote periodic test of the fire pump system. Providing a remote monitoring system to replace the normal inspection, testing, and maintenance ITM periodic test and inspections will require a lot of pre-planning and engineering in addition to the standard or custom NFPA 20 installation.

The remote monitoring equipment required to provide the necessary data delves into a lot more electronics such as cameras, thermal screening, video, and other electronic devices. In our evaluation, we could not determine that these proposed items added any value or better fire protection for the end-user. Adding self-regulating pumps and remote monitoring to the standard added several areas of concern.

We as fire sprinkler professionals must evaluate the application of these products to ensure we provide the fire protection needed by our customers. The new self-regulating variable speed pump system is totally different in concept when compared to the variable speed controls used extensively in excess pressure and suction control applications. As fire protection professionals and licensed fire sprinkler contractors, you should pay more attention to determining the exact cause and effect of problems we encounter during design, installation, and operating of fire pump systems.

Record this information and make it available for future reference. The need for more and more factual record keeping is becoming an everyday requirement. Stay ahead of the game and establish an in-depth event recording program. Chapter 4 General Requirements, reflects a large number of text changes that include clarifications in section 4. Beginning at Chapter 4 section 4. Additionally, new guidance is provided for use of water flow devices.

Beginning at section 4. New section 4. Sections 4.Fire pump accessibility status: passed.

The 2019 edition of the NFPA 20 and NFPA 14 Handbook is now available. Find out what’s new!

A proposal was submitted to require fire pumps that are not directly accessible from the outside to be accessible through an enclosed passageway in a fire-resistant-rated corridor from an enclosed stairway or exterior exit. These enclosed passageway portions of the building must have a fire-resistance rating not less than the fire-resistance rating of the fire pump room. Gravity feed systems—water tank refill in very tall buildings status: passed. A proposal was submitted to clarify refill requirements for fire protection water-storage tanks in high-rise buildings.

This includes permitting refilling from a primary water supply tank for a different vertical fire protection zone located above the refill valve i. Redundant refill capacity is required for each tank and tank compartment.

Each refill connection must be made to a different riser; all refill connections for tanks supplying the same vertical zone must be interconnected. In addition, each tank must be provided with an overflow sized for the maximum refill rate with a single automatic refill valve operating fully open. Changes to NFPA 20 that impact high-rise fire protection systems. Since NFPA 20 started requiring access to the fire pump room in an earlier edition, there has been confusion over building codes not permitting access to mechanical spaces from exit corridors.

This attempts to clear up the confusion. The intent of the requirement is to provide the fire department access to the fire pump room in an emergency. Automated inspection and testing status: passed. A proposal was submitted to add provisions for automated inspection and testing.

Devices, meters, and equipment used to monitor or perform automated inspection and testing procedures that are subjected to system pressure must be listed.

Automated inspection and testing devices and equipment installed on the fire pump system must be tested to ensure the accuracy of the automated inspection and testing devices and equipment. Automated testing devices and equipment are required to produce the same action required by manual testing to test a device and must discharge water where required by this standard and NFPA In case of a failure of a component or system to pass an automated inspection or test, the automated system must generate an audible trouble signal in accordance with NFPA With proper design, this permits automated testing of waterflow switches in tall buildings.

The design of high-rise buildings should implement the highest level of automated testing available at the time of the design. This can reduce testing costs and increase reliability through automated reporting and by allowing an increased testing frequency with minimal cost impact.

Pumps are required to refill tanks, but refill redundancy can be provided by gravity refill from a tank located higher in the building. One advantage of this design approach is the fire pump and standpipe control valves will almost always be below the floor where a fire occurs, providing access to the fire pump and valves without exposure to the fire. One advantage of a gravity-fed system is the system will function without power and without fire pumps operating.

Designing fire protection systems in high-rise buildings requires evaluating pressure implications with multiple design options.

Very tall buildings are typically light-hazard occupancies where the standpipe demand is greater than the sprinkler system demand.

The maximum required flow rate required by NFPA 14 is 1, gpm gpm for the first standpipe riser and gpm for the next two standpipe risers for a fully sprinklered building, which must be maintained for 30 minutes. This requires 30, gal of water. NFPA 14 requires the water supply to provide psi residual pressure at the topmost outlet.

For a gravity-fed standpipe system to provide psi at the top of the standpipe zone, the tank must be located a minimum of ft above the top of the zone.

NFPA standards go through multiple processes before formal acceptance and publication.NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection offers comprehensive requirements for fire pumps, limited service controllers, and pumps in series.

Annex C is revised significantly to make data formatting more universal. The requirements for hydraulic cranking systems are revised to distinguish between systems used as primary cranking systems and those used as secondary cranking systems. New definitions include the term very tall building, and the requirements pertaining to this type of building are expanded, including those for automatic tank refill valves.

New definitions for alternate power and standby power. The terms appear in several provisions of the previous edition but were not defined.

A power source that is independent of the primary power supply. An alternate power source that is normally inactive but becomes active whenever the primary power is lost.

Definitions were added to address new technology related to fire pumps using variable-speed drivers and controllers. Definitions were added for Automated Inspection and Testing and Distance Monitoring, and new provisions were added recognizing and permitting this technology. For example, in paragraph 4.

Suction diffusers are now permitted, provided they are listed for fire protection service. Vertical Fire Protection Zone. Very Tall Building. A high-rise building where the fire protection water demand exceeds the pumping capacity of the fire department. These terms appear in Section 5.

Note that the actual height of a very tall building is not defined, as it depends on the capabilities of the fire department. Annex note 4. Paragraph 4. This new wording was a compromise, as committee members desiring to have the fire pump system equipment supplied by a single entity lost out to those that felt it would restrict competition from third parties with perfectly acceptable equipment.

Let the buyer beware. New paragraph 4. The nameplate shall indicate the maximum pump horsepower demand required to power the pump at any flow, including flows beyond percent of the rated capacity. Restricting Orifice Identification. A new item requiring all restricting orifices including those in check valves to be identified with a permanent tag.

A new provision requiring that listed indicating valves cannot be closed from the fully open condition in less than 5 seconds. Automated Valves. A new section addressing requirements for indicating valves that are automated.

Allows fire-pump relief-valve discharge lines to be combined pump test discharge lines under certain conditions. Added several new subparagraphs that describe conditions where fire pump test headers are permitted to be manifolded. Tables 4. There are several modifications to paragraphs related to the evaluation of backflow prevention devices.

Note there are several changes to this section. A new requirement prohibiting water piping from being extended into a fire pump controller. A new provision permitting a remote stop station, provided it is within sight of the electric fire pump controller.While these read-only online documents cannot be downloaded or printed, they are available anyone who wants to familiarize themselves with a code or check a requirement.
