Revised Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (First Revision) which is identical with ISO 8201 : 2017 ‘Alarm systems - Audible emergency evacuation signal - Requirements’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Functional Requirements in Buildings Sectional Committee and approval of the Civil Engineering Division Council.

This Indian Standard was first published in 1993, which was identical with ISO 8201 : 1987. This revision aligns with the latest version of ISO 8201 and supersedes IS 13735 : 1993 ‘Audible emergency evacuation signal ? Specification’. Therefore, IS 13735 : 1993 is withdrawn with the publication of this standard.
