Introduction
Smoke and heat exhaust ventilation systems (SHEVS) create a smoke free layer above the floor by
removing smoke and thus improve the conditions for the safe escape and/or rescue of people and
animals and the protection of property and permit the fire to be fought while still in its early stages.
They also exhaust hot gases released by a fire in the developing stage.
The use of smoke and heat exhaust ventilation systems (SHEVS) to create smoke free areas beneath
a buoyant smoke layer has become widespread. Their value in assisting in the evacuation of people
from construction works, reducing fire damage and financial loss by preventing smoke logging,
facilitating fire fighting, reducing roof temperatures and retarding the lateral spread of fire is firmly
established.
Pressure differential systems are also available to assist in the evacuation of people, fire fighting and
the reduction of smoke migration.
For these benefits to be obtained it is essential that smoke and heat control systems operate fully and
reliably whenever called upon to do so during their installed life. A heat and smoke control system is a
scheme of safety equipment intended to perform a positive role in a fire emergency.
Components for smoke and heat control systems should be installed as part of a properly designed
smoke and heat control system.
Smoke and heat exhaust ventilation systems help to:
keep the escape and access routes free from smoke,
facilitate fire fighting operations by creating a smoke free layer,
delay and/or prevent flashover and thus full development of the fire,
protect equipment and furnishings,
reduce thermal effects on structural components during a fire,
reduce damage caused by thermal decomposition products and hot gases.
Powered SHEVS should operate based on powered ventilators. The performance of the powered
smoke and heat exhaust system depends on:
the temperature of the smoke,
the size, number and location of the exhaust openings,
the wind influence,
the size, geometry and location of the inlet air openings,
the time of actuation,
the location and conditions of the system (for example arrangements and dimensions of the
building).
SHEVS are used in buildings or construction works where the particular (large) dimensions, shape or
configuration make smoke control necessary. Typical examples are:
single and multi-storey shopping malls,
5
---------------------- Page: 7 ----------------------
OSIST prEN 12101-7:2004
prEN 12101-7:2004 (E)
single and multi-storey industrial buildings and warehouses; atria and complex buildings,
enclosed car parks,
stairways,
tunnels,
theatres.
Depending on differing circumstances and the situation of the building or construction works that can
affect their performance, powered or natural smoke and heat control systems or pressure differential
systems may be used.
It is specified in Parts 4 and 6 of this European Standard that powered and natural exhaust ventilators
shall not be used to extract smoke and hot gases from the same smoke reservoir.
Special conditions apply where gas extinguishing systems (e.g. according to EN 12094 or
EN ISO 14520) are used (see prEN 12101-4 and 6). It is the purpose of this standard to provide the
additional requirements for smoke control system ducts to operate in these hostile conditions.
A number of different system designs are commonly in use to fulfil this function and separate into
three distinct groups. These are:
i) natural dedicated smoke and/or heat control systems,
ii) powered dedicated smoke and/or heat control systems,
iii) powered smoke and/or heat control systems that are used during the day to day running
of the building or construction works and otherwise provide an environmental air
provision function.
Each can then be separated further into smoke and/or heat control systems that serve a single fire
compartment and those that, by the provision of smoke ducts, serve or pass through a number of fire
compartments.
When a system is to be provided, it is necessary to ensure that any components do not fail and cause
failure of the smoke and/or heat control system whilst working to control heat and/or smoke. Thus all
components are tested to meet the performance requirements of the smoke control system duct into
which they are to be installed following the principles described in this standard.
The components installed within a system are generally to:
allow access to the duct for cleaning and inspection of ancillaries (e.g. access doors/panels),
limit noise (silencers, attenuators),
control air distribution within parts of the smoke control system duct (turning vanes at bends,
volume control system ducts, etc.),
give air flow/volume indication, and
provide structural support to the system and control the direction of air/smoke movement at the
terminals of the system (grilles).

4 Applications
4.1 General
4.1.1 Functions and installation
Smoke control systems are designed to fulfil three basic functions. These are:
a) the extraction of smoke from a single fire compartment to the outside of the building,
b) the extraction of smoke from fire compartments of a building, using a SHEVS connected to one
or more fire compartments. The smoke control system duct may or may not pass through other
compartments of the building to reach the outside of the building,
c) the use of pressurisation to maintain smoke free clear areas.
Smoke control system ducts are commonly used in smoke and heat control systems as a means of
limiting the number of high temperature fan units. The ducts may serve single compartments or a
number of different fire compartments. The systems may be dedicated smoke extract or possibly a
combined environmental ventilation/smoke extract.
The smoke control system may remove smoke using either high temperature fans (in accordance with
EN 12101-3) or natural ventilators (in accordance with EN 12101-2).
Smoke control system ducts shall maintain their cross sectional area within defined limits.
NOTE It is not unusual for the velocity in this type of system to be from 10 to 20 m/s. It is recommended that
a velocity of 20 m/s should be the maximum considered.
4.1.2 Specific fire resistant duct types
4.1.2.1 Duct A
Vertical duct, which is able to resist the fire from outside as fully described in EN 1366-1.
4.1.2.2 Duct B
Horizontal duct, which is able to resist the fire from inside and outside as fully described in EN 1366-1.
4.1.2.3 Duct C
Horizontal duct, which is able to resist the fire from inside and outside as fully described in prEN 1366-8.
4.1.3 Single compartment smoke control system ducts
A smoke control system duct that is used for the extraction of smoke from a single fire compartment to
the outside of the building without passing through another fire compartment (see Figure 1).
4.1.4 Multi compartment fire resisting smoke control system ducts
A smoke control system
