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.

As applicable in the body of the code as well as any related annexes, all references to NFPA 70, TheNational Electrical Code, should be made to the entire document instead of a specific article unlesstechnically required.


Referencing a specific article in the NEC can lead to confusion and potential enforcement issues. For example many times only Article 760 is referenced leading some to believe that is the only part of the NEC that applies and not following or acknowledging the charging requirements established in Article 90-.

Add a new Annex as follows:

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

(CPSC) Guidelines for Fire and other Emergency First Response Personnel.

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.

Fire-warning equipment to be installed in residential occupancies shall produce the audible emergencyevacuation signal described in ANSI S3.41, American National Standard Emergency Evacuation Signal,whenever the intended response is to evacuate the building.

Carbon monoxide warning equipment to be installed in residential occupancies shall produce the T-4signal. After the initial 4 minutes of alarm, the 5-second "off" time of the alarm signal shall be permitted tobe changed to 60 seconds - 10 percent.

Exception: Where mechanically powered single-station heat alarms are used as supplementary devices,unless required by applicable laws, codes, or standards, such devices shall not be required to produce theemergency evacuation signal described in ANSI S3.41.


The Standards Council approved the consolidation of NFPA 720 and NFPA 72 and directed the current material that is within the existing NFPA 720 to be relocated into the next edition of NFPA 72. The Correlating Committee on Signaling Systems for the Protection of Life and Property appointed the 720/72 Consolidation Task Group to review and effect the necessary changes.

29.3.8

Notification appliances provided in sleeping rooms and guest rooms for those with hearing loss shallcomply with 29 18 . 3.8.1 and 29.3.8.2 , as applicable.

29.3.8.1 * Mild to Severe Hearing Loss.

Notification appliances provided for those with mild to severe hearing loss shall comply with the following:

(1) An audible notification appliance producing a low frequency alarm signal shall be installed in thefollowing situations:

(2) Where required by governing laws, codes, or standards for people with hearing loss

(3) Where provided voluntarily for those with hearing loss

(4)

29.3.8.2 * Moderately Severe to Profound Hearing Loss.

(1)


4.5.3.


Audible notification provided as a result of a smoke alarm activation (chapter 29) in sleeping areas should be held to the same standard as system audible appliances. This is a correlation issue. It is a technical issue in that several studies have PROVEN that low frequency appliances AWAKEN sleeping occupants. In apartment, hotel, motel, condo, and similar occupancies we have had to enforce TWO different standards which is hard to explain to anyone. Please correlate this requirement or at least recognize the findings from the technical studies! The requirements as written are VERY difficult to enforce. The occupants and their degraded hearing changes daily. It also changed from one occupant to another.

Public Input No. 318-NFPA 72-2016 [ Section No. 29.3.8.1 ]

29.3.8.1 * Low Frequency Smoke Alarms

Effective January 1, 2023, smoke alarms installed in sleeping areas shall be capable of producing afundamental frequency of 520 Hz ± 10 percent.

29.3.8.1 Mild to Severe Hearing Loss.

Notification appliances provided for those with mild to severe hearing loss shall comply with the following:

(1) An audible notification appliance producing a low frequency alarm signal shall be installed in thefollowing situations:

(2) Where required by governing laws, codes, or standards for people with hearing loss


(4) * The low frequency alarm signal output shall comply with the following:

(5) The waveform shall have a fundamental frequency of 520 Hz ±10 percent.

(6) The minimum sound level at the pillow shall be 75 dBA, or 15 dB above the average ambientsound level, or 5 dB above the maximum sound level having a duration of at least 60 seconds,whichever is greater.


The language currently outlined in section 29.3.8.1 requires a low frequency alarm signal in sleeping areas only when the occupant has mild to severe hearing loss. Code officials and AHJs have no way in determining during the design phase of a building if occupants will have mild to severe hearing loss. This makes this section as written unenforceable. There are many different occupancies outlined in the model codes that require compliance with NFPA 72 chapter 29; including but not limited to: hotel/motels, apartments, dormitories, and assisted livings, in addition to single family homes.

This change is intended to serve two purposes: 1. Give smoke alarm manufacturers adequate time to develop low frequency smoke alarm technology, have the smoke alarm listed by a nationally recognized testing agency, and on the market by 1/1/23. 2. It also is intended to provide clarification to AHJs that low frequency smoke alarms, based on research, are more effective at waking sleeping individuals than the 3000 Hz smoke alarm.

(3) A restraining means shall be used at the plug-in of any cord-connected installation unless the unitutilizes a secondary (standby) power source meeting the requirements of 29 .6 and loss of the ACprimary power source results in annuncaition of an audible trouble signal meeting 29.7.6.4.


(5) Operation of a switch (other than a circuit breaker) shall not cause loss of primary (main) power.Operation of a ground-fault circuit-interrupter (GFCI) receptacle shall not cause loss of primary (main)power. Smoke alarms powered by branch circuits protected by arc-fault circuit-interrupters (AFCI) orGFCI circuit breakers shall have a secondary power source.





The requirement for a restraining means appears to have been included when products were not required to utilize a secondary power source and loss of the AC power was annunciated only by the extinguishing of a visual indicator. The restraining means that case is warranted to preclude disabling the product via inadvertent dislodging of the plug or disconnecting the plug to plug in a different product. The annunciation of an audible trouble signal meeting 29.7.6.4 to alert the user when the plug has been dislodged or disconnected provides warning to reattach the plug to the receptacle and addresses the initial concerns.

This option also addresses newer receptacles which do not have a center screw for attachment of the receptacle cover. The variability in the construction of receptacles poses issues for manufacturers to provide a uniform restraining means. Rather than a mechanical means, less reliable restraining means are being proposed such as the use of double sided tape - some of which are only one time use.

(3) A restraining means shall be used at the plug-in of any cord-connected installation. Alternatively, amarking stating that the power source must not be unplugged may be used to discouragedisconnection of the power source.


(5) Operation of a switch (other than a circuit breaker) shall not cause loss of primary (main) power.Operation of a ground-fault circuit-interrupter (GFCI) receptacle shall not cause loss of primary (main)power. Smoke alarms powered by branch circuits protected by arc-fault circuit-interrupters (AFCI) orGFCI circuit breakers shall have a secondary power source.





Third-party certification labs including UL and Intertek have created internal Engineering Judgement documents that essentially require a mounting tab and screw for power supplies to satisfy this "restraining means" requirement. As a result, many manufacturer's installation instructions state that the power source must be secured using a screw in the mounting tab on the power source. New screwless wall plates do not include a screw as the standard and Decora wall plates do. Therefore, instructing an installer to use a screw to secure the power supply to a screwless wall plate could result in a severe safety hazard. If an installer follows the manufacturer's written instructions, a self-drilling screw or such could inadvertently be used to satisfy the manufacturer's installation requirement. Therefore, an alternative method should be permitted.The requirement for a “restraining means” originated back when the heavy “wall transformers” were used which were quite bulky and could be easily bumped and dislodged from the receptacle. The modern power supply designs available today are much lighter and narrower and much less likely to be accidentally bumped and dislodged from the receptacle, so a label identifying the function would minimize the inadvertent removal concern for the power supply. The NFPA 72 Handbook states that the reason for the requirement was due to “…accidental bumping of the plug or inadvertent removal…”. People should be discouraged from removing the power source from the receptacle. This can be accomplished using a marking on the power source. Although double sided adhesive could be used as a restraining means on a screwless wall plate, that becomes fairly permanent and the power source cannot be readily disconnected in the event of a catastrophic failure. Please consider allowing a marking as an alternative restraining means.

(Intertek has informally suggested they will adhere the same date.) As a result, it is not possible to expect the 2019 date to be met.The new edition of the standard(s) has hundreds of changes which will require redesign, testing, and certification of virtually every alarm and detector on the market. There is no way to know how long redesign will take nor when a majority of manufacturers will be ready to begin testing, nor how long it might take for all testing to be completed, giving the physical constraints of testing facilities. In addition, an anonymous survey of NEMA members suggested that more than half might not be ready to begin testing by the 2020 date.

The existing code language for 29.8.3.4(8) creates conflicts when it is physically impossible to locate smoke alarms and detectors 36 inche or more from the tip of a fan blade. The proposed change provides a means to be code compliant under these circumstances. The study by Elyse Gottuk (see attached presentation to SUPDET 2015, "Effect of Ceiling Fans on Smoke Alarm Performance") demonstrates that the proposed language should be acceptable without creating an unacceptable risk.

Effect of Ceiling Fans on Smoke

Alarm Performance

Elyse Gottuk

Dan Gottuk

Background

• Smoke alarms and smoke detectors shall not be installed within a 36 in. (910 mm) horizontal path from the tip of the blade of a ceiling-suspended (paddle) fan. [NFPA 72 – 29.8.3.4 (8)]

• Not always possible

Example of Potential Problem

4 ft

8.5 ft

8.5 ft2.25 ft

3.0 ft

Background – Safety Questions?

• Will a ceiling fan prevent smoke from getting to the alarm? Does the fan direction matter?

• Will a fan dilute the smoke and prevent or delay the smoke alarm from sounding?

• Will different alarm locations be better than the three foot requirement?

Objective

• To determine the effect of a ceiling fan on the performance of smoke alarms.

• To determine if the 3 ft requirement is valid or if closer distances can be used.

Approach

• Ran fire experiments in a 17 x 17 x 8 ft high room.

• 2 paper fire locations

• 8 ionization smoke alarms

• Fan conditions:

▫ Fan off

▫ Slow and Fast

▫ CW and CCW

Experimental Setup

Experimental Setup

Fires

• 100 grams of shredded paper in a 9x9 inch steel pan

Procedure

1. Set the fan on the predetermined speed and direction (ex. Fast, counter clockwise)

2. Turn the data acquisition system on for 60 seconds before igniting the fire

3. Light the fire, leave the room and shut the door4. Wait for all the smoke alarms to alarm and then

extinguish the fire

Ran each test condition 3 times (except no fan condition run once for each fire location)

Results – All Tests with Fire in Corner

Results – All Tests with Fire in Corner

Results – All Tests with Fire near Center

Results – All Tests with Fire near Center

Safety Questions?

• Will a ceiling fan prevent smoke from getting to the alarm? NO

• Does the fan direction matter? Generally NO, particularly for 3 ft and longer

Results – Fan Direction

Safety Questions?

• Will a fan dilute the smoke and prevent or delay the smoke alarm from sounding?

▫ Fan operation delays detection (typ~34 s with a range of 15-65 s).

▫ Fast speed ~25 s longer to alarm than slow speed.

Safety Questions?

• Will different alarm locations be better than the three foot requirement?

▫ For fires near the center, no significant difference in alarm locations.

▫ For fires in the corner, little difference for most, except a CW fast fan where 3 ft or larger had faster alarm times.

Results – Smoke Alarm Location

Conclusion

• Ceiling fans negatively affect smoke alarm performance. The faster the fan, the slower the response.

▫ Fan operation delays detection (typ~34 s with a range of 15-65 s).

▫ Fast speed ~25 s longer to alarm than slow speed.

• The direction of the fan does not typically matter.

Conclusion

• The location of smoke alarms only matters in a few scenarios.▫ For fires near the center, no significant difference in alarm locations.

▫ For fires in the corner, little difference for most, except a CW fast fan where 3 ft or larger had faster alarm times.

• Tests should be done with smaller rooms• The code requirement should allow for closer spacing when 3 ft is not physically possible.

The cooking nuisance test is now been defined in ANSI/UL 217 and ANSI/UL 268 and is required for smoke alarm and detector certification. All products certified by UL LLC must comply with this requirement by May 29, 2020. Therefore, inclusion of such a requirement in NFPA 72 is like stating that a smoke alarm shall be capable of detecting smoke or that a smoke alarm shall be resistant to surge immunity tests.

In addition, the installation location requirements in NFPA 72 for cooking/kitchen installations should be reconsidered to determine if these installation locations should remain, be revised, or be removed. In addition, should additional research be conducted to consider a modified installation location?

1104 of 1374 6/30/2016 11:10 AM

the word "Listed" in their certification mark. The use of "approved" in this context is not correct, since it is defined as being acceptable to the AHJ. The term "certification organization" is also more accurate than "testing laboratory", and covers both the testing and certifications aspects of the organization.

A.29.3.5

The use of the distinctive three-pulse temporal pattern fire alarm evacuation signal has been recommendedby this Code since 1979. It has since been adopted as both an American National Standard (ANSI S3.41,American National Standard Audible Emergency Evacuation Signal) and an International Standard (ISO8201, Audible Emergency Evacuation Signal).

Copies of both of these standards are available from either of the following:

(1) The web at asa.aip.org/map_publications.html

(2)

(3) Standards Publication Fulfillment, P.O., Box 1020, Sewickly, PA 15143-9998, Tel. 412-741-1979

For information about the Acoustical Society of America, or for how and why the three-pulse temporalpattern signal was chosen as the international standard evacuation signal, contact Standards Secretariat,Acoustical Society of America, 35 Pinelawn Road, Suite 114E, Melville, NY 11747, Tel. 531-490-0215,Email: [email protected].

The standard fire alarm evacuation signal is a three-pulse temporal pattern using any appropriate sound.The pattern consists of the following in this order:

(1) An “on” phase lasting 0.5 second ±10 percent.

(2) An “off” phase lasting 0.5 second ±10 percent for three successive “on” periods.

(3) An “off” phase lasting 1.5 seconds ±10 percent [see Figure A.29.3.5(a) and Figure A.29.3.5(b) ]. Thesignal should be repeated for a period appropriate for the purposes of evacuation of the building, butfor not less than 180 seconds. A single-stroke bell or chime sounded at “on” intervals lasting 1 second±10 percent, with a 2-second ±10 percent “off” interval after each third “on” stroke, is permitted [seeFigure A.29.3.5(c)].

The minimum repetition time is permitted to be manually interrupted.

A.29.5.2.1

Hazardous concentrations of carbon monoxide can accumulate in a residence, generally from improperlyoperating heating appliances, insufficient make-up air into the residence or space, or blocked chimneys orvents. However, there are many other potential sources of carbon monoxide within a home, including, butnot limited to, the following:

(1) Malfunctioning fossil fuel–burning appliances

(2) Wood stoves

(3) Fireplaces

(4) Idling automobiles in attached garages

(5) Portable equipment such as gasoline-powered lawn and garden equipment and electric powergenerators

(6) Barbecues

Carbon monoxide is odorless, tasteless, and colorless; therefore, its presence is undetectable by smell,taste, or sight. Carbon monoxide can be mixed and migrate throughout a residence through the HVACsystem. Carbon monoxide alarms meeting the requirements of ANSI/UL 2034, Standard for Single andMultiple Station Carbon Monoxide Alarms , and installed in accordance with this standard should provide asignificant level of protection against fatal carbon monoxide exposure.

The installation of additional carbon monoxide alarms could result in a higher degree of protection. Addingalarms to rooms where fuel-burning appliances are located could provide earlier warning of carbonmonoxide hazards caused by those sources. Additional alarms located in rooms normally closed off fromthe required alarms could increase the escape time, since the carbon monoxide concentration needed toforce the carbon monoxide out of the closed rooms to the alarms would not be necessary. As aconsequence, the installation of additional carbon monoxide alarms should be considered.

Carbon monoxide alarms or detectors are not substitutes for proper maintenance, inspection, and testing offuel-burning equipment. Fuel-burning equipment and appliances should be used, maintained, tested, andinspected according to the manufacturers' instructions.

Carbon monoxide detectors/alarms are cross sensitive to hydrogen, an explosive gas that can be given offby recharging lead acid batteries. Where households include recharging stations (e.g., for golf carts), thealarm should be located away from the recharging location.

A.29.5.2.1.1

Where sleeping areas are separated and the audibility of the alarm or detector to occupants within eachsleeping area could be seriously impaired, more than one unit could be needed.

At times, depending on conditions, the audibility of notification appliances could be seriously impaired whenoccupants are in the bedroom area. For instance, there might be a noisy window air conditioner or roomhumidifier generating an ambient noise level of 55 dBA or higher. The detection device alarms need topenetrate through the closed doors and be heard over the bedroom's noise levels with sufficient intensity toawaken sleeping occupants. Test data indicate that alarms with ratings of 85 dBA at 3 m (10 ft) that areinstalled outside the bedrooms can produce about 15 dBA over ambient noise levels of 55 dBA in thebedrooms. This sound pressure is likely to be sufficient to awaken the average sleeping person.

Alarms or detectors located remote from the bedroom area might not be loud enough to awaken theaverage person. In such cases, it is recommended that units be interconnected in such a way that theoperation of the remotely located detector or alarm causes an alarm of sufficient intensity to penetrate thebedrooms. The interconnection can be accomplished by the following:

(1) Installation of a system

(2) Wiring together of multiple-station alarms

(3) Use of line carrier or radio frequency transmitters/receivers

(4) Adding supplemental notification appliances
