NFPA 72 National Fire Alarm Code

Tentative Interim Amendment
National Fire Alarm Code®
1999 Edition
Reference: 8.0,,,, 8.4.1,
TIA 99-1 (NFPA 72)
Pursuant to Section 5 of the NFPA Regulations Governing Committee Projects, the National Fire Protection Association has
issued the following Tentative Interim Amendment to NFPA 72, National Fire Alarm Code®, 1999 edition. The TIA was
processed by the Signaling Systems for the Protection of Life and Property Committee, and was issued by the Standards Council
on January 18, 2001 with an effective date of February 7, 2001.
Tentative Interim Amendment is tentative because it has not been processed through the entire standards-making procedures. It
is interim because it is effective only between editions of the standard. A TIA automatically becomes a proposal of the
proponent for the next edition of the standard; as such, it then is subject to all of the procedures of the standards-making process.
1. Add Section 8-0 (to be renumbered as 8-1 in next edition) as follows:
8-0 Scope. This chapter shall address the selection, installation, operation, and maintenance of fire warning
equipment for use within dwelling units. The requirements of other chapters shall not apply except where otherwise
2. Add new 8-1.2.5 to read as follows:
8-1.2.5 All devices, combinations of devices, and equipment to be installed in conformity with this chapter shall be
listed for the purposes for which they are intended.
3. Add the following as a last sentence to 8-1.2.2:
“Since hearing deficits are often not apparent, the responsibility for advising the appropriate persons of the existence
of this deficit shall be that of the hearing impaired party.”
4. Revise 8-1.2.3 by adding a new last sentence so that 8 -1.2.3 reads as follows:
8-1.2.3* Newly installed fire warning equipment for dwelling units (including self-contained devices) shall produce
the audible emergency signal described in ANSI S3.41, Audible Emergency Evacuation Signal, whenever the
intended response is to evacuate the building. The same audible signal shall be permitted to be used for other
devices as long as the desired response is immediate evacuation. Signals from notification appliances shall not be
required to be synchronized.
Exception: Fire warning equipment that is installed in accordance with provisions of this chapter in other than
dwelling units, unless required by another chapter.
5. Reword 8-4.1 to read as follows:
8-4.1 Fire alarms systems complying with 8-3.1 shall have two independent power sources consisting of a primary
source that uses the commercial light and power source and a secondary source that consists of a rechargeable
battery or standby generator that can operate the system for at least 24 hours in the normal condition followed by 4
minutes of alarm.
6. Add new 8-1.4.5 to read as follows:
8-1.4.5 Where more than one smoke alarm is required to be installed for new construction, they shall be arranged so
that the operation of any smoke alarm causes the alarm in all smoke alarms within the dwelling to sound.
Exception: This arrangement shall not be required for configurations that provide equivalent distribution of the
alarm signal as required by 8-1.2.2.
