EN 12101-1:2005 (E) 6 0 Introduction 0.1 General Smoke and heat exhaust ventilation systems (SHEVS) create a smoke free layer above the floor by removing smoke and heat, 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. 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 SHEVS operate fully and reliably whenever called upon to do so during their installed life. A SHEVS is a scheme of safety equipment intended to perform a positive role in a fire emergency. Components for smoke and heat exhaust systems should be installed as part of a properly designed smoke and heat exhaust system. SHEVS 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 and contents;  reduce thermal effects on structural components during a fire;  reduce damage caused by thermal decomposition products and hot gases. For the purpose of this European Standard, a smoke barrier is deemed to be any form of barrier to the movement of fire effluent. Smoke barriers control the movement of fire effluent within a construction works in the event of fire. Smoke barriers, when used within a smoke and heat control system, become a critical element of that system. If smoke barriers are not in their fire operational position, the system will not perform as designed. However, even in the event that other elements of the SHEVS do not function, smoke barriers in the fire operational position will provide essential smoke containment and channelling. This European Standard applies to smoke barriers used within smoke and heat control systems, which include other equipment e.g. natural smoke and heat exhaust ventilators (EN 12101-2) and powered smoke and heat exhaust ventilators (EN 12101-3). Smoke barriers perform within specific time/temperature ranges. 0.2 Function of smoke barriers The function of smoke barriers is to control the movement of fire effluent within construction works by forming a barrier. The functions of active or manually deployed smoke barriers are identical to those of static smoke barriers, but they also have the ability to be retracted and concealed when not in use. Typical functions of smoke barriers are:

EN 12101-1:2005 (E) 7  to create a smoke reservoir by containing and limiting the travel of the smoke;  to channel smoke in a pre-determined direction;  to prevent or retard smoke entry to another area or void. 0.3 Applications of smoke barriers The primary applications of smoke barriers are listed below. However, as their application becomes more widespread, it is inevitable they will be put to a wider variety of uses. It should be noted that, within the scope of this standard, smoke barriers can contain smoke and gases in excess of 600 °C but are not intended to perform the same function as fire barriers, smoke control doors which show conformity with (or are tested against) EN 1634-1 and –3, unless they meet the additional temperature requirements found in Table 2. Typical applications for smoke barriers are:  smoke reservoir boundaries;  channelling screens;  void edge screens;  void sealing screens;  corridor containment;

 shop unit containment;  escalator containment;  stairwell containment;  elevator well containment. 0.4 Types of smoke barrier Construction works elements can be used to create static smoke barriers, and they can be augmented by smoke barriers covered by this standard. This European Standard applies to the following types of smoke barriers:  static smoke barriers: (SSB),  active smoke barriers: (ASB). A wide range of different materials may be used to create smoke barriers. Typical materials used for static smoke barriers include fabric, glass, metal, fire-resisting board, fibreglass and mineral wool or any impermeable material capable of resisting the smoke at temperatures required by the design. Typical examples of active smoke barriers include roller, pleated, folding, hinged or sliding, using the types of material as described for static smoke barriers. Static and active smoke barriers are categorized by type and performance in Clause 4. In addition an ASB product is deemed to include all controlling equipment etc. This does not include external controls, for example a fire alarm or a sprinkler flow switch.

EN 12101-1:2005 (E) 8 1 Scope This part of EN 12101 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.

EN 12101-1:2005 (E) 11 4 Product requirements 4.1 General NOTE The smoke barrier requirements are intended to provide the SHEVS designers with smoke barriers which fulfil the system design requirements. Compliance with EN 12101-1 does not necessarily, by itself, ensure fitness for purpose for an application, as defined in ISO/IEC Guide 2:1996. The system design parameters will dictate the minimum classification and performance of smoke barriers which can be used in any particular application. The criteria for the correct choice of smoke barrier shall take into account the total system, function and location requirements without hindering the means of escape or endangering the occupants. 4.2 Barrier types 4.2.1 General Smoke barriers shall be defined as one of the following types:  static smoke barrier - flexible material;  static smoke barrier - rigid material;  active smoke barrier - flexible material;  active smoke barrier - rigid material. 4.2.2 Static smoke barriers (SSB) Static smoke barriers shall be fixed in their fire operational position at all times and according to their design classification. NOTE Static smoke barriers are used as alternatives and/or additional to the elements of the construction works which could act as permanent static smoke barriers. 4.2.3 Active smoke barriers (ASB) Active smoke barriers shall move to the fire operational position upon external initiation and according to their design classification. Active smoke barriers shall be defined according to their application, e.g. life safety protection or property protection, method of operation and external initiations. NOTE 1 Active smoke barriers are used as alternatives and/or additional to elements of the construction works which could act as permanent static smoke barriers. Active smoke barriers shall be categorized as follows: ASB1: Smoke barriers which fail safe in/to the fire operational position (not lower than 2,5 m above the finished floor level or in any location hazardous to occupants or objects), in a controlled manner (see 5.4) when all consumable primary and auxiliary power sources are removed, in the event of wiring or system corruption, or any combination thereof. ASB2: Smoke barriers which move to/stay in the fire operational position (not lower than 2,5 m above the finished floor level or in any location hazardous to occupants or objects), in a controlled manner (see 5.4) upon external initiation but requiring a consumable power source in order to move to or be maintained in the fire operational position. ASB3: Smoke barriers, conforming to type ASB1, which can be deployed to any height (see 5.4).

EN 12101-1:2005 (E) 12 ASB4: Smoke barriers conforming to ASB2, which can be deployed to any height (see 5.4). In the majority of applications active smoke barriers shall fail safe. But if it is necessary for the smoke barrier to remain retracted, even in the event of fail safe, the system shall be so designed and tested. NOTE 2 ASB1 and ASB3 do not require fire rated cables or cable systems. NOTE 3 Active Smoke Barriers without the fail safe facility i.e. those requiring a power source to drive them down (ASB2 and ASB4), require fire rated cables or cable systems in accordance with prCEN/TR 12101-4. NOTE 4 In certain applications smoke barriers are used for life safety applications where types ASB1 and ASB3 may be more fit for purpose. 4.3 Auxiliary power supply If batteries are used as the primary or auxiliary power source (types ASB2 and ASB4), batteries shall be submitted to an active battery test at intervals not exceeding 60 min. During this test the connected load shall be at least 110% of the normal motor current and shall be powered solely from the battery set. A fault indicating signal shall be given as a volt free contact and as an optical indication on the control panel upon:  battery set insufficiently charged;  faulty battery set (e.g. short circuit);  battery set not connected to load (e.g. open circuit). Upon detection of a fault signal the active smoke barrier shall move to the fire operational position. Other stored energy systems shall have an equivalent level of monitoring and shall be capable of moving the barrier to its fire operational position upon detection of a fault signal. Power supplies shall comply with regulatory requirements valid in the place of use. 4.4 Smoke (fire effluent) leakage 4.4.1 Openings, gaps and/or perimeter spaces The free area through and around the complete system, materials and joints inherent in the product design shall be stated by the manufacturer. All gaps in and around all types of smoke barrier shall be minimized to maintain the smoke barrier containment efficiency as defined in 5.5. Deflection of a smoke barrier may occur due to pressure differences or air movement. This may increase edge gaps or reduce effective smoke reservoir depth. The system design shall take this into consideration (see 5.5.2). NOTE 1 Care should be taken to ensure that any adjacent surfaces which form part of the barrier
