EN 12094-6:2006 (E) 5 Introduction It has been assumed in the preparation of this European Standard that the execution of its provisions is entrusted to appropriately qualified and experienced people. All pressure data in th
29、is European Standard are given as gauge pressures in bar, unless otherwise stated. NOTE 1 bar = 105N m-2= 100 kPa. EN 12094-6:2006 (E) 6 1 Scope This European Standard specifies requirements and test methods for non-electrical disable devices for CO2, Inert gas- or Halocarbon gas fire extinguishing
30、systems. Examples are: a) an isolating valve in the pipework to the flooding zone or in a pneumatic pilot line; b) a device blocking the actuator at the bank of containers or the container valve in single-zone installations or the actuator of selector valves in multiple-zone installations. 2 Normati

34、h-pressure installation fire extinguishing installation in which the CO2is stored at ambient temperature. For example, the pressure of the CO2in storage is pabs= 58,6 bar at 21 C 3.4 CO2-low-pressure installation fire extinguishing installation in which the CO2is stored at low temperature, normally
35、19 C to -21 C 3.5 disabled state state of the non-electrical disable device, when operated and disabling the release of the extinguishing agent into the flooding zone EN 12094-6:2006 (E) 7 3.6 Halocarbon Gas extinguishing agent that contains as primary components one or more organic compounds contai
36、ning one or more of the elements fluorine, chlorine, bromine or iodine 3.7 Halocarbon Gas installation fire extinguishing installation in which the Halocarbon Gas is stored at ambient temperature 3.8 Inert Gas non liquefied gas or mixture of gases which extinguish the fire mainly by reducing the oxy
37、gen-concentration in the protected zone, such as Argon, Nitrogen or mixtures of these gases with CO23.9 Inert Gas installation fire extinguishing installation in which the Inert Gas is stored at ambient temperature 3.10 non-electrical disable device component that prevents any kind of unintentional
38、release (automatic or manual) of fire extinguishing systems during maintenance work in the protected room or object, without disabling the fire detection and alarm functions 3.11 operational state state of the non electrical disable device, when not operated and not disabling the release of the exti
39、nguishing agent into the flooding zone 3.12 quiescent condition condition when the system is ready to operate 3.13 working pressure pressure at which the component is used in the system 4 Requirements 4.1 General design 4.1.1 Disable devices except seals shall be made of metal. All mechanical parts
40、of the actuator shall be made of metal. Operating moving parts shall be manufactured of stainless steel, copper, copper alloy or corrosion-protected steel (e.g. galvanised steel). All materials shall be resistant to media with which they come into contact. 4.1.2 The non-electric disable device shall
41、 isolate either the mechanical and/or pneumatic release triggering or the flooding of a single zone. NOTE Guidelines for planning and installation may require that each flooding zone can be disabled separately. If the design of the non-electrical disable device prevents the disablement of each flood
42、ing zone in multi zone systems separately, the manufacturer shall limit the use of the component to single zone systems only. 4.1.3 The disabled and the operational states shall be clearly indicated. This indication shall be given at the non-electrical disable device itself. EN 12094-6:2006 (E) 8 Th
43、e non-electrical disable device shall be lockable in the disabled and operational states. 4.1.4 The non-electrical disable device shall not affect the fire detection and pre-warning alarms. The requirement is fulfilled, if compliance is made possible by the design. NOTE Guidelines for planning and i
44、nstallation may require that fire detection and pre-warning alarms are not affected, when the non-electrical disable device is in the disabled state. 4.1.5 The test sample shall comply with the technical description (drawings, parts list, description of functions, operating and installation instruct
45、ions) when checked in accordance with 5.3. 4.1.6 The component shall be specified by the manufacturer either for installation on walls only or for installation on both walls and machinery. 4.1.7 The non-electrical disable device shall be able to be reset from the disabled state to the operational st
46、ate, when the system is in the quiescent condition, and also when the system is in the activated condition. 4.2 Disabling valves Pilot line disabling valves shall vent any pressure from the pilot line to the atmosphere between disabling valve and the actuator when in the disable position. This may b
47、e done by using a 2-position, 3-port ball valve. NOTE Standards for planning and installation may require monitoring of the status of isolating valves. For valves in the pipework to the flooding zone and in pilot lines the requirements of 4.1, 4.4, 4.5 and Clause 6 of this European Standard and the
48、applicable clauses of EN 12094-5 shall apply. Applicable clauses of EN 12094-5 for selector valves covering the requirements and the relevant test methods shall be as follows: General design; Connection threads and flanges; Function and ambient temperature (requirements for opening and closing time
49、are not relevant); Internal pressure and leakage; Resistance to bursting; Operational reliability; Flow characteristics (only for valves in the pipework to the flooding zone); Corrosion; Stress corrosion; Vibration. 4.3 Disable devices other than valves 4.3.1 Connection threads Connection threads shall comply with European or International Standards for threads, e.g. ISO 7-1 and EN ISO 228-1.
