This document (EN 12094-1:2003) has been prepared by Technical Committee CEN / This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2003, and conflicting national standards shall be withd rawn at the latest by April 2006.
This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.
This European Standard is part of a series concerned with gas extinguishing system components.

Introduction
It has been assumed in the preparation of this standard that the execution of its provisions is entrusted to appropriately qualified and experienced people.
All pressure data in this European Standard are given as gauge pressures in bar, unless otherwise stated.
NOTE 1 bar = 10 5 N m' 2 = 100 kPa. 1 Scope
This European Standard specifies requirements and test methods for electrical automatic control and delay devices (e.c.d.) for use in combination with automatic fire detection and fire alarm systems and CO 2 -, Inert Gas- or Halocarbon Gas-Fire Extinguishing Systems installed in buildings.
The standard specifies compulsory functions which shall be provided on all electrical automatic control and delay devices and optional functions (options with requirements) which may be provided.
Additional functions associated with fire extinguishing can be provided, but are not covered by this standard.
