Foreword
This European Standard was prepared by a joint working group of CLC/TC 205, Home and Building
Electronic Systems (HBES) and CEN/TC 247, Building Automation, Controls and Building Management
(BACS).
The text of the draft was submitted to the Unique Acceptance Procedure and was approved by CENELEC
as EN 50491-2 on 2010-03-01.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
The following dates were fixed:
– latest date by which the EN has to be implemented

at national level by publication of an identical

national standard or by endorsement
(dop) 2011-03-01

– latest date by which the national standards conflicting

with the EN have to be withdrawn
(dow) 2013-03-01
As a result of the discussions at the CLC/TC 205 meeting on 2004-10-5/6 concerning the structuring of
their standards in general parts and open system parts (see CLC/TC 205/Sec0413/INF) the following new
parts of EN 50491 under the generic title “General requirements for Home and Building Electronic
Systems (HBES) and Building Automation and Control Systems (BACS)“ under the task of the JWG
CEN/TC 247-CLC/TC 205 are proposed:
Part 2 Environmental conditions;
Part 3 Electrical safety requirements;
1)
Part 4-1 Functional safety requirements (for non safety related systems);
