Yakine, Michael Alternate Fire Suppression Systems Association Chase, Barry Staff Liaison National Fire Protection Association

The Chair asked NFPA Staff to provide staff remarks and process training.

NFPA Staff Representative, Barry Chase, Fire Protection Engineer, provided staff procedural

remarks and training on the new process.

Chair asked for a motion regarding the meeting agenda. Kenneth Schneider made a motion to

approve the agenda with a second by Jack McNamara.

Chair asked for a motion regarding the meeting minutes for the first draft meeting held June

24‐25, 2013 in St. Louis, Missouri. Jack McNamara made a motion to approve the minutes as

submitted with multiple callers on the phone seconding the motion.

Chair called for task group reports:

o At the first draft meeting a task group (TG) was assigned with John Cholin assigned to

head up the group to resolve the issues from PI‐350, PI‐351, PI‐352 and PI‐353.

Unfortunately John was not on the phone call so an update and/or TG

recommendation was not provided.

Chair directed the committee to review and process public comments related to SIG‐IDS

second revision:

o The committee reviewed and disposed of the five public comments submitted.

o The committee also discussed a few possible second revision committee actions

however none were processed.

o One public comment was rejected but held due to the complexity of the issues it

raised. To resolve this issue substantial research would be needed to determine all

the possible conflicts between the various chapters and the initiating device chapter.

The SIG‐IDC committee voted to form a TG to further study the issue for the 2019

edition. Those selected to be on this TG include Ken Dungan, Lynn Nielson and

Kenneth Schneider.

Other business was then requested by the chair:

o A discussion was held related to initiating device placement information for devices

used in for machine room less smoke detectors. The committee decided to request a

possible joint task group with SIG‐PRO for the 2019 edition. The TG would review the

initiating device location found in SIG‐PRO. Lee Richardson, NFPA Staff Engineer,

indicated that he would discuss this with SIG‐PRO Chair Merton Bunker when the SIG‐

PRO committee meets later in the week.

o A discussion was also held related to the criteria provided for air aspirating initiating

devices. Currently specific location, design, methods and materials requirements are

not provided but instead a pointer to the manufacturers’ installation instructions is

provided. The committee decided to form a TG to further study this issue for the 2019

edition. Those that expressed a willingness to participate on this TG include: Scott

Galley (who also volunteered to be the chair of the TG) John Chetelat, Sam Miller,

Mike Nelson, Kenneth R. Schneider, Ken Dungan and one committee member whose

name was not captured.

Closing remarks & expressions of gratitude for participation by Chair.

Motion for adjournment was made and seconded by various members on the conference call.

The meeting was adjourned at approximately 10:15 a.m.

o Following the meeting several callers on the conference call stated that they could

not clearly hear those speaking in the room due to poor intelligibility. NFPA staff

stated that those in the room need to speak VERY LOUDLY to be heard by those on

the call. Conference callers also asked about the Adobe Connect software attendee

gesture status indicators (i.e., raise hand) wanting to know if these were being

monitored during the meeting. They were told that these were not being monitored.

NFPA Staff indicated that these items should be discussed at the next meeting during

the meeting procedures discussion.

Public Input No. 210-NFPA 72-2016 [ Global Input ]

Rewrite the "Exception" text throughout NFPA 72 and replace with standard subsection text.

Statement of Problem and Substantiation for Public Input

NFPA 72 contains numerous sections that are written with "Exception" text. This is inconsistent the direction provided in the Manual of Style and should be corrected. Differing types of style that are inconsistent with the MOS create confusion as the proper application of the code by the end user.

As an example, 10.4.4 is currently written with an "exception" as follows:

"10.4.4* In areas that are not continuously occupied, automatic smoke detection shall be provided at the location of each fire alarm control unit(s), notification appliance circuit power extenders, and supervising station transmitting equipment to provide notification of fire at that location.Exception: Where ambient conditions prohibit installation of automatic smoke detection, automatic heat detection shall be permitted."

This section could easily be rewritten to be consistent with the MOS in the following manner with the exception becoming core text in a subsection modifying 10.4.4:

10.4.4* In areas that are not continuously occupied, automatic smoke detection shall be provided at the location of each fire alarm control unit(s), notification appliance circuit power extenders, and supervising station transmitting equipment to provide notification of fire at that location.10.4.4.1 Where ambient conditions prohibit installation of automatic smoke detection, automatic heat detection shall be permitted.

The above is just one example but applies throughout to all "exception" text in NFPA 72.

X.1 Guideline Summary. How public emergency response organizations

respond to carbon monoxide (CO) incident calls is

essential for the safety of the building occupants and the emergency

responders. One reference that can be helpful to emergency

responders is the Consumer Product Safety Commission

This guide is designed to help emergency responders to act

quickly and effectively when they receive a call concerning CO

poisoning. The guide contains basic information needed when

responding to a CO incident and provides procedures for:

(1) Dispatchers answering a call

(2) Incident reporting forms to help emergency responders

identify the elevated source of carbon monoxide, the

level of care needed by occupants, and when it is safe for

occupants to return to the building

(3) Advice and actions to give building occupants

This proposal merely moves UL standards from Section 2.3.1 ANSI Publications to a new Section 2.3.6 titled UL Publications. Other NFPA codes such as NFPA 101, 13, etc. treat UL referenced standards in this same manner. The move will make it easier for code users to locate UL referenced standards. Assume existing Section 2.3.6 will be renumbered 2.3.7.

In separate public inputs we proposed updates to UL referenced standards, and introduced new referenced standards. If those changes are accepted they should be relocated to this section.

Also assume staff can delete these ANSI/UL standards are deleted from Section 2.3.1.

John Dove – Badge # 090

Fire Alarm Inspection Unit

Bureau of Fire Prevention

9 METROTECH CENTER – BROOKLYN, NY 11201

(718) 999-1610

Dear NFPA (Fire Alarm and Signaling committee)

My name is John Dove, Associate Electrical Inspector (A.E.I)

for the New York City Fire Department. I have installed, tested,

maintained and inspected many types of Fire alarm systems

throughout New York City as a Certified Technician and Inspector

for most of my career.

I am respectfully writing this letter on behalf of myself, Fire

Alarm industry professionals and not necessarily in the interest

of the New York City Fire Department but who have expressed

concern over the National Fire Protection Associations (NFPA)

official definition of an Alarm Box which shall apply to the

descriptive term "MANUAL FIRE ALARM BOX" used in the code. The

term contained in the Definitions chapter as well as the Manually

Actuated Alarm- Initiating Device chapter of NFPA 72 (National

Fire Alarm and Signaling Code) editions is the accepted term for

this particular Fire alarm equipment but unfortunately does not

directly reflect the defined ordinarily accepted meaning within

the context in which it is used. The words "ALARM BOX or MANUAL

FIRE ALARM BOX" is mis-leading and can be at times unclear

therefore subjecting the applied definition to different

interpretations. The definition expressed for a student within

"Webster's Dictionary for Students" published in the United

States reflects the word "TERM" to mean a word or expression that

has an exact meaning in some uses or is limited to a subject or

field and the word "ALARM" to mean a device (as a bell) that

warns or signals people, (example: alarm clock). Fire alarm

system components such as a frequently tested "MANUAL FIRE ALARM

BOX" does not make any physical warning or signaling alarm sound

when activated. The manual pull lever or key releasing actuation

of this securely mounted and stationed device is controlled by

the Fire alarm system and electrically transmits a closed circuit

short signal across a pair of wires to the supervising panel

which will then activate the alarm sound through a separate

audible notification appliance connected to the system. Without

any audible device connected to a supervising control panel and

the manual actuation of the "MANUAL FIRE ALARM BOX" there would

be no warning or sounding alarm that signals people.

Furthermore, the initial intent of the device when installed is

to provide people with an accessible and manual means of alerting

a supervising station and or central monitoring company of a

possible life safety condition which does not require in some

cases any audible alarm sounding notification appliances to be

connected (example: Residential R-2 occupancy classifications).

For these reasons and any other examples that may not have been

defined in this letter we believe that this Fire alarm equipment

description term is inadvertently incorrect.

I formally propose a revision to the NFPA documents to now

reflect the words "FIRE ALARM PULL STATION and or MANUAL FIRE

ALARM PULL STATION". This term is more commonly used by industry

contractors, Fire alarm vendors, Technician's, Inspectors and

licensed Engineers within the state of New York, easily

interpreted during an administered examination and more

reflective to the actual function of the device. It is a

manually operated device with a pull lever and it is stationary.

Please consider my efforts and the interpretation of others.

Thank you for your cooperation.

Sincerely,

John Dove/ A.E.I

NFPA 72 does not address spacing considerations for smoke detection based on ceiling heights. It does have a table for heat detection. There has been confusion in design and code enforcement on what to do when smoke detectors are installed on higher ceilings.This public input offers a template and location for this information. Research is needed, and is planned to set the reduction of the listed space based on ceiling heights. This research data should be available by the NFPA 72 Public Comment period, and this table will be updated. It should be noted, the figures shown are the estimated spacing detection values.

Public Input No. 702-NFPA 72-2016 [ Section No. 17.6.3.5.2 ]

17.6.3.5.2 * Spacing Minimum.

The minimum spacing of heat detectors shall not be required to be less than 0.4 times the height of theceiling.


From Design of Smoke Management Systems, Klote and Milke, equations 10.18 through 10.21, there is an evaluation of the plume temperature with respect to the ceiling height and with respect to distance from plume centerline. As can be seen from equation 10.21, the VISIBLE diameter of the plume is approximately half of the ceiling height. Annex B of NFPA 72, Section B.4.9.1, provides a slightly more conservative figure for the VISIBLE plume diameter to be approximately 0.4 times the ceiling height. However, Annex B.4.9.1 discusses spacing of beam detectors, not spacing of heat detectors. The analysis may be appropriate for smoke-sensing devices, but breaks down for heat-sensing devices. As can be seen from comparing equations 10.18 and 10.20 from Klote/Milke, the EXCESS TEMPERATURE plume diameter is exactly half of the VISIBLE diameter. The EXCESS TEMPERATURE is defined to be the point in the plume where the smoke temperature is one-half of the plume centerline temperature. The annex to 17.6.3.5.2 indicates that the factor of 0.4 is chosen because “the width of uniform temperature of the plume when it impinges the ceiling is approximately 0.4 times the height above the fire”. This does not coincide with the information provided by Klote/Milke, which indicates a decay of plume temperature away from the plume centerline. Following the Klote/Milke information would yield a lower limit of 0.25 ceiling height. Since this is less than the smallest factor from Table 17.6.3.5.1, no lower limit is necessary. Therefore, since there is a question as to the adequacy of the 0.4 factor used in Section 17.6.3.5.2, this section and the associated annex material are to be deleted.

Smoke Spot-type smoke detectors that have provision for field adjustment of sensitivity via a mechanicalmeans shall have an adjustment range of not less than 0.6 percent per foot (1.95 percent per meter)obscuration.


The existing text dates back to the days when smoke alarms had mechanical adjustments for sensitivity. In looking at UL 217, the requirement is interpreted as a mechanical adjustment in section 17.2.1 of the eighth edition. As currently written in NFPA 72 2016, the requirement may create confusion if it is viewed within the context of high sensitivity aspirated detectors, which have sensitivity settings outside of the normal UL range of 0.5 to 4%/ft. Aspirated detectors have a number of very high sensitivity threshold settings that may not differ by the amount required in 17.7.2.2.

17.7.3.1.3

If the intent is to protect against a specific hazard, and the detectors are not otherwise requried by thiscode or other applicable codes, the detector(s) shall be permitted to be installed closer to the hazard in aposition where the detector can intercept the smoke.


The intent is to limit the use of 17.7.3.1.3 only to situations where an owner/user is adding detectors for protection of a certain piece of equipment. The language of 17.7.3.1.3 seems to imply that smoke detectors must be allowed to be installed outside of its listings and other code requirements for all situations, so long as the argument is made that the detector is closer to a specified hazard. There is nothing in the rest of NFPA 72 that prohibits placing a required smoke detector close to the hazard, but such installation is required to comply with listing and spacing requirements. For instance, for areas with tall ceilings, past practice in various parts of the country has allowed for the installation of the smoke detector on the wall, more than 12 inches from the ceiling, just above the “hazard” being protected. This has been used for elevator lobby recall in tall lobbies, and for protection of the fire alarm control panel. It both cases, the smoke detector placed on the wall ignores the effects of a fire that can be close to the “hazard”, and still not be close enough to have the plume impinge on the wall. Waiting for the smoke to fill the room, and bank down to wherever the smoke detector is installed, delays the response time of the detector, and could lead to the elevator opening onto a floor area with a developed fire. It is imperative to limit this code section only to non-required installations in order to ensure that base code forces required smoke detectors to be placed on or near the ceiling.

This change is a result of that task group's efforts. Additionally, the task group proposed a complete re-write of section 17.7.3.6.

Exception. For Low Air Pressure Dry Valves the High and Low pressure values shall be set per themanufacturer's installation instructions.


Some of the newer dry valves use lower air pressures in the area of 14-15 PSI only, instead of the traditional 40 PSI range. A plus or minus value of 10 PSI is not appropriate for these valves and may result in system discharge prior to the low air pressure supervisory signal. A value of 5 PSI plus or minus may be more appropriate but I believe that these values should be set by the valve manufacturer for these low pressure systems and not be required to abide by the current requirement. The current requirement does not allow for any deviation as it stated as a hard value of 10 PSI above or below the set point.

(B)

The off-normal signal shall be initiated when the pressure increases or decreases by 10 psi (70 kPa) or perthe dry valve manufacturers instructions .


The 10 psi change is for high differential dry valves. There are now low differential dry valves on the market that the installation instructions specifically state not to put more than 5 psi of pressure above the minimum pressure allowed.

(B)

The off-normal signal shall be initiated when the pressure increases or decreases by 10 psi (70 kPa) as setaround the dry valve air compressor settings for high pressure dry valves and have preset psi settings forlow pressure dry valves as determined and set by the manufactuer in order to provide ample notice inadvance of the pending off-normal state .



Victaulic_30.80.pdf Victaulic Dry Valve Low Pressure


Recently I can across a situation that addresses the need to amend the air pressure supervisory requirements as stated in NFPA 72 2016 paragraph 17.16.2.2.2 Dry Pipe Sprinkler Systems (B) that states that the off-nominal signal shall be initiated when the pressure increases or decrease by 10 psi (70kPa).

In the attached brochure you will see on page five that this cannot be applied here as well as with other manufacturers that make a similar type of dry fire sprinkler valve. New dry sprinkler valves work at much lower pressures and therefore they do not have such leeway in the pressure settings. This manufacturer’s stated required and working pressure is 13 psi (90kPa), the trip pressure is 7 psi, the low air pressure setting of by the manufacturer of the air supervisory switch is 10 psi with a high air setting of 22 psi (as stated to me in a telephone call to them). Only their supplied switch can be used since they are made/set specifically by the manufacturer to be used with this dry fire sprinkler valve because of the pressure settings. Perhaps this paragraph should now be changed as to state “as set and determined by the dry fire sprinkler valve manufacturer” without stating an exact number like now.

Please review my information and advise me if this change is of value and will be considered.

(B)

The off-normal signal shall be initiated when the pressure increases or decreases by 10 psi (70 kPa) amaximum of 50% of the differential between the low pressure setting and component trip pressure and/orwithin 10 psi of hi/low pressure settings .


Due to the introduction of Low Pressure and Extra Low Pressure dry valves and dry actuators many dry systems can now operate with air pressures set below 10 psi. With these valves and actuators with set pressures between 8 and 13 psi requiring a specific value of 10 psi increase or decrease is no longer appropriate and should be changed to reflect these new low pressures.

Total coverage requires that a fire above the suspended ceiling be detected. Detector spacing and locationfor above- ceiling spaces are addressed in 17.7.3.5.2. If that above-ceiling space is used as an air returnplenum, this detection can be provided either by smoke detectors placed in accordance with 17.7.4.2 orwhere the air leaves the smoke compartment in accordance with 17.7.5.4.2.2.

An example of a fire scenario in a computer room might be as follows.

The computer room is 9.1 m × 6 m (30 ft × 20 ft) and 2.8 m (8 ft) high. It is occupied 12 hours a day, 5 daysa week. The occupants are mobile and familiar with the building. There are no fixed fire suppressionsystems protecting this location. The fire department is capable of responding to the scene in 6 minutes,and an additional 15 minutes for fire ground evolution is needed.

Overheating of a resistor leads to the ignition of a printed circuit board and interconnecting cabling. Thisleads to a fire that quickly extends up into the above- ceiling space containing power and communicationscabling. The burning of this cabling produces large quantities of dense, acrid smoke and corrosive productsof combustion that spread throughout the computer suite. This causes the loss of essential computer andtelecommunications services for 2 months.

(1) Time expected for occupants to hear the alarm (due to sleeping or manufacturing equipment noise)

(2) Time to decipher the message (e.g., voice/ alarm system)

(3) Time to decide whether to leave (get dressed, gather belongings, call security)

(4) Time to travel to an exit
