WHAT'S NEW IN NFPA 72-2002? PART I
----------------------------------

Just when you thought you could remember where to find the answer
within NFPA 72, the chapters change. Three new chapters were
added in 2002, to bring it into conformance with the NFPA Manual
of Style. The word Appendix has been replaced with Annex. Metric
units have taken the place of English units, which now appear in
parentheses. The hyphen (2-3.4.6.1) has been changed to a dot
(2.3.4.6.1).

I'll outline each 2-digit article (1.1, 1.2, 2.1, 2.2, etc.) for
each chapter and include what I think are important changes. If
I leave the article blank then I feel that there is no change or
that the change is made to clarify existing requirements or that
exception language has morphed into enforceable language.
CAPS ARE MY COMMENTS.

Chapter 1 Administration
NEW CHAPTER

1.1 Scope

1.2 Purpose
1.2.4*  This Code shall not be interpreted to require a level of
fire protection that is greater than that which would otherwise
be required by the applicable building or fire code.
A.1.2.4  Some building and fire codes include requirements that
imply NFPA 72 requirements that do not exist. The intent of this
paragraph is to make it clear that the protection requirements
are derived from the applicable building or fire code, not from
NFPA 72.

1.3 Application

1.4 Retroactivity

1.5 Equivalency

1.6 Units and Formulas. Standard units in the Code are
International System (SI) of Units. Where presented, inch-pound
units follow the SI units in parentheses.

1.7 Code Adoption Requirements. This Code shall be administered
and enforced by the authority having jurisdiction designated by
the governing authority. (See Annex D for sample wording for
enabling legislation.)

Chapter 2 Referenced Publications
NEW CHAPTER

2.1 General

2.2 NFPA Publications

2.3 Other Publications

Chapter 3 Definitions
NEW CHAPTER

3.1 General

3.2 NFPA Official Definitions

3.3 General Definitions
3.3.18 Average Ambient Sound Level. The root mean square,
A-weighted, sound pressure level measured over the period of time
that any person is present, or a 24-hour period, whichever time
period is the lesser.

3.3.55 Effective Masked Threshold. The minimum sound level at
which the tone signal is audible in ambient noise.

3.3.117* Occupiable Area. The spaces of a facility that can be
occupied or used by the facility occupants as part of the
building function or to support building operations and
maintenance. This includes, but is not limited to, storage areas,
mechanical and electrical equipment areas, walk-in closets or
janitor’s rooms, restrooms, conference rooms, and individual
offices.
A.3.3.117 Occupiable Area. The space above a suspended ceiling
that does not have permanent walkways or in crawl spaces or
attics that do not contain building support equipment is not
considered an occupiable space. If a large attic or crawl space
contains building support equipment in one area only,
notification appliances would only be required in the area of
the building support equipment where the potential exists for
building maintenance personnel being present for equipment
maintenance.

3.3.124* Ownership. Any property or building or its contents
under legal control by the occupant, by contract, or by holding
of a title or deed.
A.3.3.124 Ownership. Inspection testing and maintenance is the
responsibility of the system owner or can be transferred by
contract. The system owner can include but is not limited to a
landlord, tenant, financing company, or an alarm company.

3.3.118 Octave. The bandwidth of a filter that comprises a
frequency range of a factor of 2. (That is, f2 = 2f1 as defined
in IEC 61260. For example, for an octave-band centered on 500 Hz,
the lower frequency is 353 Hz, and the upper frequency is 707 Hz).

3.3.118.1 One-Third Octave. The bandwidth of a filter that
comprises a frequency range of a factor of 2^1/3. (That is,
f2 = 2^1/3 f1 as defined in IEC 61260). The octave filter can be
subdivided into three  octave-bands.

Chapter 4 Fundamentals of Fire Alarm Systems
FORMERLY CHAPTER 1

4.1 Application

4.2 Purpose

4.3 Equipment and Personnel

4.4 System Fundamentals
4.4.1.5.3.1  Unless otherwise permitted or required by
4.4.1.5.3.1(A) or 4.4.1.5.3.1(B), the secondary power supply
shall have sufficient capacity to operate the fire alarm system
under quiescent load (system operating in a nonalarm condition)
for a minimum of 24 hours and, at the end of that period, shall
be capable of operating all alarm notification appliances used
for evacuation or to direct aid to the location of an emergency
for 5 minutes.
THE ENTIRE POWER SUPPLY SECTION HAS BEEN RE-WRITTEN. I ASSUME
THAT THE 60-HOUR SECONDARY POWER REQUIREMENT FOR REMOTE STATION
SYSTEMS WAS DRIVEN BY THE FACT THAT TROUBLE SIGNALS, INCLUDING
LOSS OF PRIMARY POWER, WEREN'T NECESSARILY TRANSMITTED TO A
CONSTANTLY ATTENDED LOCATION, HOWEVER, NFPA 72 REQUIRES THAT A
TROUBLE SIGNAL BE TRANSMITTED TO A REMOTE STATION (SEE NFPA 72-
1999 1-5.4.6.2, NFPA 72-1993 1-5.4.6.2, AND NFPA 71-1990 2-4.2.1)
(A) The secondary power supply for emergency voice/alarm
communications service shall be capable of operating the system
under quiescent load for a minimum of 24 hours and then shall be
capable of operating the system during a fire or other emergency
condition for a period of 15 minutes at maximum connected load.
THE UNENFORCEABLE LANGUAGE, TWO HOURS OF EMERGENCY OPERATION, WAS
REMOVED IN FAVOR OF THE ENFORCEABLE 15 MINUTE REQUIREMENT.
(B) The secondary power supply capacity for supervising station
facilities and equipment shall be capable of supporting
operations for a minimum of 24 hours.

4.4.1.6.1  The secondary power supply shall automatically provide
power to the protected premises fire alarm system within 10
seconds, whenever the primary power supply fails to provide the
minimum voltage required for proper operation.
THIS IS DOWN FROM 30 SECONDS IN NFPA 72-1999.

4.4.1.6.2  The secondary power supply shall automatically provide
power to the supervising station facility and equipment within 60
seconds whenever the primary power supply fails to provide the
minimum voltage required for proper operation.

4.4.1.6.3  Required signals shall not be lost, interrupted, or
delayed by more than 10 seconds as a result of the primary power
failure.
I INTERPRET THIS AS REQUIRING AT LEAST A MINIMAL BATTERY-SET TO
BE INSTALLED ON ALL FIRE ALARM SYSTEMS INCLUDING THOSE THAT ARE
PROVIDED POWER BY EMERGENCY STANDBY SYSTEMS.

4.4.1.8.1* Marking. Batteries shall be permanently marked with
the month and year of manufacture.
MARKING IS TO HELP ENSURE THAT BATTERIES ARE REPLACED WITHIN 5
YEARS OF THE DATE OF MANUFACTURE
(SEE NFPA 72-2002 TABLE 10.4.3 6(D)1.
A.4.4.1.8.1  Markings for month and year can be applied by the
manufacturer or in the field based on the manufacturer's date
code.

4.4.1.9.3 Secondary Power Supplies.
4.4.1.9.3.1 Protected Premises.
(A)  Engine-driven generators used to provide secondary power for
a protected premises fire alarm system shall comply with
NFPA 110, Standard for Emergency and Standby Power Systems,
Section 2.2, requirements for a Type 10, Class 24, Level 1 System.
Installation shall be in accordance with NFPA 70, National
Electrical Code, Article 700.
(B)  Where survivability of circuits is required by Chapter 6,
equal protection shall be provided for power supply circuits.
SURVIVABILITY REQUIREMENTS ASSOCIATED WITH EVAC SERVICE.
4.4.1.9.3.2 Supervising Station.
(A)  Automatic-starting, engine-driven generators used to provide
secondary power for a supervising station shall comply with
NFPA 110, Standard for Emergency and Standby Power Systems,
Section 2.2, requirements for a Type 60, Class 24, Level 2 system.
Installation shall be in accordance with  NFPA 70, National
Electrical Code, Article 701.
(B)  Manual-starting, engine-driven generators used to provide
secondary power for a supervising station shall comply with
NFPA 110, Standard for Emergency and Standby Power Systems,
Section 2.2, requirements for a Type M, Class 24, Level 2 system.
Installation shall be in accordance with  NFPA 70, National
Electrical Code, Article 702.

4.4.7.3.3*   Supervising station fire alarm systems shall be
arranged to delay transmission of primary power failure signals
for a period ranging from 60 to 180 minutes.
Exception:  Where delay of the signal is prohibited by the
authority having jurisdiction, delay of the transmission shall
not be required.
A.4.4.7.3.3  This requirement is intended to prevent all of the
supervising station fire alarm systems in a given geographic area
from transmitting simultaneous trouble signals (and overwhelming
the associated supervising stations) in the event of a widespread
power failure.
60 TO 180 MINUTES REPLACES 25-50%.

4.5.2 Completion Documents.
4.5.2.1* Preparation. The preparation of a record of completion,
Figure 4.5.2.1, shall be the responsibility of the qualified and
experienced person described in  4.3.3 and shall be in accordance
with  4.5.2.1(A) and  4.5.2.1(B).
THIS REPLACES THE STATEMENT THAT A RECORD OF COMPLETION SHALL BE
PREPARED FOR EACH FIRE ALARM SYSTEM.
A.4.5.2.1  The requirements of Chapter  10 should be used to
perform the installation wiring and operational acceptance tests
required when completing the record of completion.

4.5.2.4* Verification of Compliant Installation. Where required,
compliance of the completed installation with the requirements of
this standard, as implemented via the referring code(s),
specifications, and/or other criteria applicable to the specific
installation, shall be certified by a qualified and impartial
third-party organization acceptable to the authority having
jurisdiction.
PUTTING A FINER POINT ON 3RD PARTY VERIFICATION.
A.4.5.2.4  This section is intended to provide a basis for the
authority having jurisdiction to require third-party verification
and certification that the authority having jurisdiction and the
system owner can rely on to reasonably assure that the fire alarm
system installation complies with the applicable requirements.

4.6 Impairments
THIS IS A NEW SECTION TO BETTER DESCRIBE HOW TO HANDLE SYSTEM
IMPAIRMENTS.

CONSPICUOUS BY ITS ABSENCE IS CERTIFICATION AND PLACARDING
BECAUSE IT WAS MOVED TO CHAPTER 8 (SUPERVISING STATION FIRE ALARM
SYSTEMS) WHERE IT BELONGS.

Chapter 5 Initiating Devices
FORMERLY CHAPTER 2

5.1 Application

5.2 Purpose

5.3* Performance-Based Design.
PERFORMANCE-BASED DESIGN IS HEREBY OFFICIALLY RECOGNIZED. ALLOW
ME TO BE THE FIRST TO VOLUNTEER AS A PERFORMANCE-BASED TESTER.
A.5.3  Annex B, Engineering Guide for Automatic Fire Detector
Spacing, provides a detailed design guide for the implementation
of the performance-based design of fire alarm systems.

5.3.1  Performance-based designs submitted to the authority
having jurisdiction for review and approval shall include
documentation, in an approved format, of each performance
objective and applicable scenario, together with any calculations,
modeling, or other technical substantiation used in establishing
the proposed design’s fire and life safety performance.

5.3.2  The authority having jurisdiction shall determine whether
such identified performance objectives are appropriate and have
been met.

5.3.3  The authority having jurisdiction shall approve
modifications to or variations from the approved design or design
basis in advance.

5.6.2.3 Marking. Heat-sensing fire detectors shall be marked with
their listed operating temperature.
THE COMMITTEE SEEMS TO HAVE GIVEN UP HOPE OF GETTING
MANUFACTURERS TO PROVIDE THE RESPONSE TIME INDEX OF HEAT-SENSING
FIRE DETECTORS.

5.7.3.2.4(A) Solid joists shall be considered equivalent to beams
for smoke detector spacing guidelines.
THIS SIMPLE STATEMENT CERTAINLY CLEARS A LOT OF THINGS UP.
NFPA 72-1999 2-3.4.6.1 DID NOT ADDRESS HIGH JOISTED CEILINGS.

5.10.1*  The provisions of Section 5.10 shall apply to devices
that initiate an alarm indicating a flow of water in a sprinkler
system.
A.5.10.1  Piping between the sprinkler system and a pressure
actuated alarm-initiating device should be galvanized or of 
onferrous metal or other approved corrosion-resistant material
of not less than 9.5 mm ( in.) nominal pipe size.
WHAT APPEARED TO HAVE BEEN NFPA 13 LANGUAGE HAS BEEN MOVED TO
THE ANNEX.

5.12.5*  Manual fire alarm boxes shall be located throughout the
protected area so that they are conspicuous, unobstructed, and
accessible.
AN ELEGANT STATEMENT. NOW IF WE COULD COMBINE THE BEST ELEMENTS
OF THIS ARTICLE WITH THE BEST ELEMENTS OF NFPA 101-2000 9.6.2.3
A MANUAL FIRE ALARM BOX SHALL BE PROVIDED IN THE NATURAL EXIT
ACCESS PATH NEAR EACH REQUIRED EXIT FROM AN AREA...
A.5.12.5  Manual fire alarm boxes should be of contrasting color
to the background on which they are mounted.
ARCHITECTS ARE NOT GOING TO BE HAPPY ABOUT THIS CONTRASTING COLOR
REQUIREMENT.

NEXT WEEK I'LL COVER THE REMAINING CHAPTERS:

Chapter 7 Notification Appliances for Fire Alarm Systems
Chapter 8 Supervising Station Fire Alarm Systems
Chapter 9 Public Fire Alarm Reporting Systems
Chapter 10 Inspection, Testing, and Maintenance
