NICET Fire Alarm Systems Level II
34006 EMERGENCY EVACUATION SIGNALS
----------------------------------

34006 is a Level II Special Work element.

34006 DESCRIPTION
Understand the recommended fire alarm evacuation signal, its
purpose, where it is used, the recommended sound pressure level
in various occupancies and modes, and how to determine the sound
pressure level needed. (NFPA 72, ANSI S1.4a 1985)

34006 DESCRIPTION BREAKDOWN:
"Understand the recommended fire alarm evacuation signal, its
purpose, where it is used, the recommended sound pressure level
in various occupancies and modes, and how to determine the sound
pressure level needed."

NFPA 72-1999 1-4 Evacuation*. The withdrawal of occupants from a
building.

NFPA 72-1999 A-1-4 Evacuation does not include the relocation of
occupants within a building.

NFPA 72-1999 1-4 Evacuation Signal. Distinctive signal intended
to be recognized by the occupants as requiring evacuation of the
building.

NFPA 72-1999 1-5.4.7 Distinctive Signals. Audible alarm
notification appliances for a fire alarm system will produce
signals that are distinctive from other similar appliances used
for other purposes in the same area. The distinction among
signals will be as follows:
(a) Fire alarm signals will be distinctive in sound from other
signals. Their sound will not be used for any other purpose. The
requirements of NFPA 72-1999 3-8.4.1.2.1 (ANSI S3.41, Audible
Emergency Evacuation Signal).
(b)* Supervisory signals will be distinctive in sound from other
signals. Their sound is not to be used for any other purpose.
Exception: A supervisory signal shall be permitted to be used to
indicate a trouble condition. If the same sound is used for both
supervisory signals and trouble signals, the distinction between
signals shall be by other appropriate means such as visible
annunciation.
(c) Fire alarm, supervisory, and trouble signals are to take
precedence, in that respective order of priority, over all other
signals.
Exception: Signals from hold-up alarms or other life threatening
signals are permitted to take precedence over supervisory and
trouble signals if acceptable to the authority having
jurisdiction.

NFPA 72-1999 A-1-4.7 (b) A valve supervisory, low-pressure switch
or other device intended to cause a supervisory signal sound when
actuated should not be connected in series with the end-of-line
supervisory device of initiating device circuits, unless a
distinctive signal, different from a trouble signal, is
indicated.

NFPA 72-1999 3-8.4.1.2.1 Distinctive Evacuation Signal. To meet
the requirements of NFPA 72-1999 1-5.4.7 (Distinctive Signals),
the fire alarm signal used to notify building occupants of the
need to evacuate (leave the building) will be in accordance with
ANSI S3.41, Audible Emergency Evacuation Signal.

NFPA 72-1999 3-8.4.1.2.2 The use of the American National
Standard Audible emergency Evacuation Signal will be restricted
to situations where it is desired that all occupants hearing the
signal evacuate the building immediately. It will not be used
where, with the approval of the authority having jurisdiction,
the planned action during a fire emergency is not evacuation, but
is the relocation of occupants or their protection in place as
directed by the firefighting personnel.

NFPA 72-1999 A-3-8.4.1.2 The use of the distinctive three-pulse
temporal pattern fire alarm evacuation signal required by
NFPA 72-1999 3-8.4.1.2.2 became effective July 1, 1996, for new
systems installed after that date. It had previously been
recommended for this purpose by this code since 1979. It has
since been adopted as both an American National Standard
(ANSI S3.41, Audible Emergency Evacuation Signal) and an
International Standard (ISO 8201, Audible Emergency Evacuation
Signal).

Copies of both of these standards are available from the
Standards Secretariat, Acoustical Society of American, 335 East
45th Street, New York, NY 10017-3483. Telephone 212-661-9404
ext. 562.

The standard fire alarm evacuation signal is a three-pulse
temporal pattern using any appropriate sound. The pattern
consists of an "on" phase (a) lasting 0.5 second " 10 percent
followed by and "off" phase (b) lasting 0.5 second " 10 percent,
for three successive "on" periods, which are then followed by and
"off" phase (c) lasting 1.5 second " 10 percent [see NFPA 72-1999
Figures A-3-8.4.1.2 (a) and A-3-8.4.1.2 (b)]. The signal should
be repeated for a period appropriate for the purposes of
evacuation of the building, but for 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, may be permitted
[see NFPA 72-1999 Figure A-3-8.4.1.2(c)].

The minimum repetition time is permitted to be manually
interrupted.

NFPA 72-1999 3-8.4.1.3.5.6.4 Loudspeakers. Each enclosed stairway
exceeding two stories in height is to be equipped with
loudspeakers connected to a separate paging zone.

NFPA 72-1999 3-8.4.1.3.6.1* Evacuation Signal Zoning. Undivided
fire or smoke areas will not be divided into multiple evacuation
signaling zones. 

NFPA 72-1999 A-3-8.4.1.3.6.1 This does not prohibit the provision
of multiple notification appliance circuits within an evacuation
zone.

NFPA 72-1999 3-8.4.1.3.6.2 If multiple notification appliance
circuits are provided within an single evacuation signaling zone,
all of the notification appliances within the zone are to be
arranged to activate simultaneously, either automatically or by
actuation of a common, manual control except where the different
notification appliance circuits within an evacuation signaling
zone perform separate functions for example, presignal and
general alarm signals, predischarge and discharge signals.

NFPA 72-1999 4-3.1.1 An average ambient sound pressure level
greater than 105dBA requires the use of a visible signal
appliance(s) in accordance with NFPA 72-1999 Section 4-4
(Visible Characteristics, Public Mode).

NFPA 72-1999 4-3.2* Public Mode Audible Requirements.

NFPA 72-1999 A-4-3.2 The typical average ambient sound level for
the occupancies specified in NFPA 72-1999 Table A-4-3.2 (Average
Ambient Sound Level According to Location) are intended only for
design guidance purposes.

The typical average ambient sound levels specified should not be
used in lieu of actual sound level measurements.

NFPA 72-1999 4-3.2.2 To ensure that audible public mode signals
are clearly heard, they will have a sound level at least 15dBA
above average ambient sound level or 5 dBA above the maximum
sound level having a duration of at least 60 seconds, whichever
is greater, measured 5 ft (1.5 m) above the floor in the
occupiable area except audible alarm notification appliances
installed in elevator cars are permitted to use the audibility
criteria for private mode appliances found in 4-3.3.2 (Private
Mode). If approved by the AHJ, audible alarm notification
appliances installed in restrooms are permitted to use the
audibility criteria for private mode appliances detailed in NFPA
72-1999 4-3.3.2 (Private Mode). If permitted by the AHJ, a fire
alarm system arranged to stop or reduce ambient noise are
permitted to produce a sound level at least 15dBA above the
reduced average ambient sound level or 5dBA above the maximum
sound level having a duration of at least 60 seconds after
reduction of the ambient noise level, whichever is greater,
measured 5 feet above the floor in the occupiable area. Visible
notification appliances will be installed in the affected areas
in accordance with NFPA 72-1999 Sections 4-4 (Visible
Characteristics, Public Mode) or 4-5 (Visible Characteristics,
Private Mode). Relays, circuits, or interfaces necessary to stop
or reduce ambient noise will meet the requirements of
NFPA 72-1999 Chapter 1 (Fundamentals of Fire Alarm Systems) and
Chapter 3 (Protected Premises Fire Alarm Systems).

NFPA 72-1999 Table 7-2.2 Test Methods.
14 Notification Appliances
a. Audible. Sound pressure level shall be measured with sound
level meter meeting ANSI S1.4a, Specifications for Sound Level
Meters, Type 2 requirements. Levels throughout protected area
shall be measured and recorded.
b. Audible Textual Notification Appliances to Convey Voice
Messages. Sound pressure level shall be measured with sound
level meter meeting ANSI S1.4a, Specifications for Sound Level
Meters, Type 2 requirements. Levels throughout protected area
shall be measured and recorded.
