33023 DESCRIPTION BREAKDOWN:
"Understand the basic principles of operation of ionization, ..."
NFPA 72-1999 1-4 Smoke Detector. A device that detects visible
or invisible particles of combustion.

NFPA 72-1999 1-4 Ionization Smoke Detection. The principle of
using a small amount of radioactive material to ionize the air
between two differentially charged electrodes to sense the
presence of smoke particles. Smoke particles entering the
ionization volume decrease the conductance of the air by reducing
ion mobility. The reduced conductance signal is processed and
used to convey an alarm condition when it meets preset criteria.

NFPA 72-1999 A-1-4 Ionization smoke detection is more responsive
to invisible particles (smaller than 1 micron in size) produced
by most flaming fires. It is somewhat less responsive to the
larger particles typical of most smoldering fire. Smoke detectors
utilizing the ionization principle are usually of the spot type.


"... aspiration, ..."
NFPA 72-1999 1-4 Air Sampling-Type Detector. A detector that
consists of a piping or tubing distribution network that runs
from the detector to the area(s) to be protected. An aspiration
fan in the detector housing draws air from the protected area
back to the detector through air sampling ports, piping, or
tubing. At the detector, the air is analyzed for fire products.


"... projected beam, photoelectric obscuration, ..."
NFPA 72-1999 1-4 Photoelectric Light Obscuration Smoke Detection.
The principle of utilizing a light source and a photosensitive
sensor onto which the principal portion of the source emissions
is focused. When smoke particles enter the light path, some of
the light is scattered and some is absorbed, thereby reducing
the light reaching the receiving sensor. The light reduction
signal is processed and used to convey an alarm condition when
it meets preset criteria.

NFPA 72-1999 A-1-4 The response of photoelectric light
obscuration smoke detectors is usually not affected by the color
of smoke. Smoke detectors utilizing the light obscuration
principle are usually of the line type. These detectors are
commonly referred to as "projected beam smoke detectors".


"... photoelectric scattering, ..."
NFPA 72-1999 1-4 Photoelectric Light-Scattering Smoke Detection.
The principle of utilizing a light source and a photosensitive
sensor arranged in a manner so that the rays from the light
source do not normally fall onto the photosensitive sensor. When
smoke particles enter the light path, some of the light is
scattered by reflection and refraction onto the sensor. The light
signal is processed and used to convey an alarm condition when it
meets preset criteria.

NFPA 72-1999 A-1-4 Photoelectric light-scattering smoke detection
is more responsive to visible particles (larger than 1 micron in
size) produced by most smoldering fires. It is somewhat less
responsive to the smaller particles typical of most flaming fires.


"... and cloud chamber smoke sensing fire detectors, ..."
NFPA 72-1999 1-4 Cloud Chamber Smoke Detection. The principle of
using an air sample drawn from the protected area into a
high-humidity chamber combined with a lowering of chamber
pressure to create an environment in which the resultant moisture
in the air condenses on any smoke particles present, forming a
cloud, The cloud density is measured by a photoelectric principle.
The density signal is processed and used to convey an alarm
condition when it meets preset criteria.


"... and the effect of stratification on response time."
NFPA 72-1999 2-3.6.1.4  Stratification.  The effect of
stratification below the ceiling shall be taken into account.
The guidelines in Appendix B shall be permitted to be used. 

NFPA 72-1999 A-2-3.6.1.4  [excerpted] Stratification of air in a
room can hinder air containing smoke particles or gaseous
combustion products from reaching ceiling-mounted smoke detectors
or fire-gas detectors.

Stratification occurs when air containing smoke particles or
gaseous combustion products is heated by smoldering or burning
material and, becoming less dense than the surrounding cooler
air, rises until it reaches a level at which there is no longer
a difference in temperature between it and the surrounding air.


"Lay out a system of smoke sensing fire detectors of line type, ..."
NFPA 72-1999 2-3.4.4.1 The beam length will not exceed the
maximum permitted by the equipment listing.
A projected beam-type detector is permitted to be used in lieu
of a single row of individual spot-type smoke detectors.


"... spot type, ..."
NFPA 72-1999 2-3.4.3.1 Spot-type smoke detectors will be located
on the ceiling not less than 4 inches from a sidewall to the near
edge or, where on a sidewall, between 4 inches and 12 inches down
from the ceiling to the top of the detector.

NFPA 72-1999 2-3.4.5.1.1 Smooth Ceiling Spacing of Spot-Type
Detectors. On smooth ceilings, spacing of 30 feet is permitted to
be used as a guide. In all cases, the manufacturer's documented
instructions will be followed. Other spacing is permitted to be
used depending on ceiling height, different conditions, or
response requirements. For the detection of flaming fires, the
guidelines in NFPA 72-1999 Appendix B is permitted to be used.

NFPA 72-1999 2-3.4.5.1.2 For smooth ceilings, all points on the
ceiling will have a detector within a distance equal to 0.7 times
the selected spacing. 

NFPA 72-1999 2-3.4.6.1 Flat Ceilings. For ceiling heights of 12
feet or lower and beam or solid joists depths of 1 foot or less,
smooth ceiling spacing running in the direction parallel to the
run of the beams or solid joists will be used and 1/2 the smooth
 ceiling spacing will be in the direction perpendicular to the
 run of the beams or solid joists. For beam over 1 foot in depth,
 spot-type detectors are permitted to be located either on the
 ceiling or on the bottom of the beams.
For beam depths exceeding 1 foot or for ceiling heights exceeding
12 feet, spot-type detectors will be located on the ceiling in
every beam pocket.
For solid joists, the detectors will be located on the bottom of
the joists.

NFPA 72-1999 2-3.4.7 Peaked. Detectors will first be spaced and
located within 3 feet of the peak, measured horizontally. The
number and spacing of additional detectors, if any, will be based
on the horizontal projection of the ceiling.

NFPA 72-1999 2-3.4.8 Shed. Detectors will first be spaced and
located within 3 feet of the high side of the ceiling, measured
horizontally. The number and spacing of additional detectors, if
any, will be based on the horizontal projection of the ceiling.

NFPA 72-1999 2-3.4.10 Partitions. Where partitions extend upward
to within 18 inches of the ceiling, they will not influence the
spacing. Where the partition extends to within less than 18
inches of the ceiling, the effect of smoke travel will be
evaluated in the reduction of spacing.


"... duct type, ..."
NFPA 72-1999 2-3.5.2.2 Detectors placed in environmental air
ducts or plenums will not be used as a substitute for open area
detectors. If detectors are used for the control of smoke spread,
the requirements of NFPA 72-1999 Section 2-10 will apply.


"... and sampling type, ..."
NFPA 72-1999 2-3.4.2 Air Sampling-type Smoke Detector. Each
sampling port of an air sampling-type smoke detector will be
treated as a spot-type detector for the purpose of location and
spacing. Maximum air sample transport time from the farthest
sampling point will not exceed 120 seconds.

NFPA 72-1999 2-3.6.4.2 Air-sampling detectors will give a
trouble signal where the airflow is outside the manufacturer's
specified range. The sampling ports and in-line filter, if used,
will be kept clear in accordance with the manufacture's documented
instructions.

NFPA 72-1999 2-3.6.4.3 Air sampling network piping and fittings
will be airtight and permanently fixed. Sampling system piping
will be conspicuously identified as SMOKE DETECTOR SAMPLING TUBE.
DO NOT DISTURB, as follows:
(a) At changes in direction or branches of piping
(b) At each side of penetrations of walls, floors, or similar
barriers
(c) At intervals on piping sufficient to provide ready visibility
within the space, but no greater than 20 feet

Sampling ports of an air sampling-type detector may be permitted
to be located above each aisle to provide coverage equivalent to
the location of spot-type detectors. The manufacturer's
recommendations and engineering judgment should be followed for
the specific installation.


"... including smoke detectors for use as area smoke detectors, ..."
NFPA 72-1999 2-3.4.4 Projected Beam-Type Smoke Detectors.
Projected beam-type smoke detectors shall be located with their
projected beams parallel to the ceiling and in accordance with
the manufacturer's documented instructions. The effects of
stratification shall be evaluated when locating the detectors.
Exception: Beams shall be permitted to be installed vertically
or at any angle needed to afford protection of the hazard
involved (for example, vertical beams through the open shaft
area of a stairwell where there is a clear vertical space inside
the handrails).

NFPA 72-1999 2-3.4.6.3 A projected beam-type smoke detector
shall be equivalent to a row of spot-type smoke detectors for
flat and sloped ceiling applications.


"... air duct smoke detectors, ..."
NFPA 72-1999 2-3.5.2.2 Detectors placed in environmental air
ducts or plenums will not be used as a substitute for open area
detectors. If detectors are used for the control of smoke spread,
the requirements of NFPA 72-1999 Section 2-10 will apply.

NFPA 72-1999 2-10.3.1  To prevent the recirculation of dangerous
quantities of smoke, a detector approved for air duct use shall
be installed on the supply side of air-handling systems as
required by NFPA 90A, Standard for the Installation of Air
Conditioning and Ventilating Systems, and 2-10.4.2.1.

NFPA 90A-1999 4-4.2 Location. Smoke detectors listed for use in
air distribution systems shall be located as follows:
(1) Downstream of the air filters and ahead of any branch
connections in air supply systems having a capacity greater than
2000 ft^3/min.
(2) At each story prior to the connection to a common return and
prior to any recirculation or fresh air inlet connection in air
return systems having a capacity greater than 15,000 ft^3/min and
serving more than one story.
Exception No. 1: Return system smoke detectors shall not be
required where the entire space served by the air distribution
system is protected by a system of area smoke detectors.
Exception No. 2: Fan units whose sole function is to remove air
from the inside of the building to the outside of the building.


"... and smoke detectors for door release service."
NFPA 72-1999 2-10.6.1 Smoke detectors that are part of an open
area protection system covering the room, corridor, or enclosed
space on each side of the smoke door and that are located and
spaced as required by 2-3.4 shall be permitted to accomplish
smoke door release service.

See NFPA 72-1999 2-10.6 for additional performance requirements
and installation guidelines including the figures found in
Appendix A.
