BS EN 12101-1:2006 – Smoke and heat control systems Part 1: Specification for smoke barriers
1 Scope This part of EN 1 21 01 specifies the product performance requirements, classifications and test methods for smoke barriers, which comprise the barrier itself, with or without associated activation and drive devices, designed for use in smoke and heat control systems. It covers only barriers installed in buildings, i.e. it does not cover barriers made of part of the building’s structure. This standard provides the test methods for, and evaluation of conformity of, the smoke barrier systems.

3 Terms, definitions and symbols
3.1 General terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN ISO 1 3943:2000 and the following apply.
3.1.1
active smoke barrier
smoke barrier which moves from its retracted position into its fire operational position automatically when called upon to do so
3.1.2
barrier movement
travel distance (e.g. height, drop) of an active barrier from its retracted position to its fire operational position
3.1.3
channelling screen
smoke barrier installed beneath a balcony or projecting canopy to direct the flow of smoke and hot gases from a room opening to the spill edge
3.1.4
consumable power supplies
any form of power that when not available will prevent an active smoke barrier moving to the required fire operational position
3.1.5
deflection
movement of a smoke barrier when subjected to the buoyant force of the hot smoke, the movement of air, air pressure, or any combination thereof
3.1.6
fail-safe
designed to return to a safe condition in the event of a failure or malfunction etc.
3.1.7
fire operational position
final configuration of a device e.g. a smoke barrier, specified by its designer to achieve and be sustained in the ultimate fire condition of the design
3.1.8
fitness for purpose
ability of a product, process or service to serve a defined purpose under specific conditions
3.1.9
free area
total area of all designed openings and clearance gaps in and/or around the perimeter of a smoke barrier
3.1.10
integrity
ability of a barrier to maintain its soundness for the purpose for which it is intended without the transmission of significant quantities of flames or hot gases to the non-exposed side
