Introduction
Objectives of pressure differential systems
Pressure differential systems offer the facility of maintaining tenable conditions in protected spaces, for
example: escape routes, firefighting access routes, firefighting lift shafts, lobbies, staircases, and other
spaces that require being kept free of smoke. It is necessary to determine not only where the fresh air
supply for pressurization is to be introduced into a building, but also where that air and smoke will leave
the building and what paths it will follow in the process.
The aim therefore is to establish a pressure gradient from the protected space to the unprotected space
(fire room) while the doors are closed, and an airflow while the doors are open.
Smoke control methods
The effect of the air movement forces, described above, are to create pressure differentials across the
partitions, walls and floors and can cause smoke to spread to spaces remote from the fire source. The
technique most commonly used to limit the degree of smoke spread, or to control its effects, is
pressurization.
System components
A typical pressure differential system will comprise three basic components:
a) components for providing supply air and to extract air;
b) components for controlling the pressure difference between the space with higher pressure and the
adjoining space with lower pressure;
c) components for releasing air flowing through the door between the space with higher pressure to
those with lower pressure (to prevent unwanted pressure build up in this space).
Installations of pressure differential systems (PDS) may comprise:
— fans (temperature rated) if necessary;
— air or smoke control ducts to provide a passageway for the transmission of air or smoke;
— ventilation openings to provide leakage of air (including dampers, active or passive controlled);
— power supply;
— connecting cables;
— means of activation;
— means of pressure control;
— control panel;
— smoke control dampers in branches from the ductwork where the ductwork is situated outside the
protected enclosure;
— grilles and diffusers;
— door closers.
The design of pressure differential systems is covered in EN 12101-13.
1 Scope
This document applies to pressure differential system kits and components, positioned on the market
and intended to operate as part of a pressure differential system. The purpose of a pressure differential
system is to prevent protected spaces from smoke spread by using pressure difference and airflow. This
document specifies characteristics and test methods for components and kits for pressure differential
systems to produce and control the required pressure differential and airflow between protected and
unprotected space.
