Introduction
Smoke and heat exhaust ventilation systems 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. It contributes to the
protection of property and permits 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 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. For these benefits to be obtained it
is essential that smoke and heat exhaust ventilators operate fully and reliably whenever called upon to do so
during their installed life. A heat and smoke exhaust ventilation system is a scheme of safety equipment
intended to perform a positive role in a fire emergency.
Components for smoke and heat exhaust ventilation systems should be installed as part of a properly
designed smoke and heat exhaust ventilation 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 damages caused by thermal decomposition products and hot gases.
A powered smoke exhaust system can also be used for the realisation of the following purposes:
 creation of a negative pressure differential facing the direction of escape for the prevention of the spread
of smoke;
 local dilution of smoke within occupied zones.
Natural smoke and heat exhaust ventilators are devices fitted into the roof and /or upper walls of a
construction works to allow smoke and fire gases to be exhausted from the construction works when driven by
thermal buoyancy inherent in those gases. It is essential that they are able to open, and/or to remain open in
the event of a fire and to fulfil their function even when climatic and weather conditions are unfavourable.
Depending on the building geometry and siting of the building with regard to neighbouring buildings, and
design criteria, natural smoke and heat exhaust ventilators can be used instead of powered smoke and heat
ventilators.
This Technical Report sets down the testing requirements for the system when installed to ensure that it
operates in a safe and reliable manner. Commissioning, periodic maintenance and servicing requirements are
stated as well as the users’ responsibilities for ensuring that the system is always for use in case of fire.
Components of the SHEVS should be designed or chosen to meet the specific performance requirement of
the system.
Without proper installation of all of its components, the SHEVS could not operate correctly nor meet the
performance targets for which it has been designed.
Commissioning is necessary to check the SHEVS operates in accordance with its design. The system has to
be permanently available for operation. This can only be achieved when checked and maintained.

SIST-TP CEN/TR 12101-4:2007
CEN/TR 12101-4:2006 (E)
4.1 Smoke and heat control system which rely on the principle of the creation of a smoke
layer
4.1.1 Smoke layers exhausted by natural vents
The needed area of vents is measured by the free area for each zone. For efficiency of the SHEVS, the
2
maximum area of a smoke zone shall not exceed 1600 m .
Air inlets have to be provided to allow for the replacement of smoke by fresh air:
 with opening in roofs
The efficiency of the vents is measured by their aerodynamic free area: A m²
w
There shall be at least one ventilator for 200 m² of floor area.
 with opening in side-wall
The efficiency of the vents is measured by their aerodynamic free area: A m²
w
Wall mounted ventilators have to be installed on at least two different sides of the building and be monitored
by wind direction control system.
4.1.2 Layers of smoke exhausted by powered vents
Smoke and heat exhaust systems in buildings provide the possibility to remove the design amount of fire
gases from the building by applying an under pressure within the smoke compartments.
The efficiency of the powered vents is measured by the capacity of the vents measured in m³/s
The number of exhaust openings needed is determined as a function of the location and its geometry
Supply of air has to be provided to allow for the replacement of smoke by fresh air The supply air has to be
provided at a speed in accordance with the DEP and to match the needs of the largest smoke zone.
4.2 Smoke free areas by differential pressure systems
This system is taken care of by EN 12101-6, therefore, it is only given for information and not taken care of by
this Technical Report.
4.3 Air renewal of the room with fresh air by dilution of smoke
The efficiency of the sytem is measured by its capacity in m³/s.
NOTE This type of principle has to be considered to fight smoke and heat.
Nevertheless it is not an installed system, it is brought to the place in case of a fire, therefore it is not within
the scope of this standard which describes only fixed installed systems.

5 Description of the combination of products for construction of SHEVS
5.1 General
The basic input to define the SHEVS, which will be used to determine the combination of products for
construction of a SHEV, is the “detailed engineering plan” . The purpose and the containt of the Detailed
engineering plan are described in Annex D .

This is valid for any principle of smoke ventilation.

The detailed engineering plan (DEP) has to be approved by the jurisdiction having authority.

5.2 General requirements
The three principles of smoke control described in 4.1 to 4.3 shall not be mixed within one room.

In the case of the layer system, natural extraction shall not be mixed with powered extraction in one smoke
zone.
Before installation, there shall be a detailed engineering plan prepared in accordance with the design
requirements and regulations valid in the place of use of the SHEVS.
The performance, the position of the components, the height of the smoke barriers and of the air inlets in
regard to the level of the smoke layer are important factors, they shall be in accordance with the DEP.
A failure of a component shall only affect the operation of that component.
Any use of the smoke and heat ventilation system for a purpose other than the ventilation of heat and smoke
under fire conditions shall not prevent the smoke and heat exhaust ventilation system from performing its
design function when required. The ventilation of heat and smoke under fire conditions shall have priority on
any other use of the system.
It shall only be possible to reset a component from the fire position to the standby position by a manual
operation.
Where one or more devices form part of the control system, components shall only be controlled by signals
coming from that control system.
All components covered by a Part of EN 12101 shall be in accordance with the relevant Part. Smoke barrier
