scope:

This part of IEC 62851 specifies the requirements and tests for manually-activated trigger devices forming part of a social alarm system.

This International Standard only applies to manually-activated trigger devices that transmit the alarm triggering signal to a local unit or controller via cable or wire-free radio transmission, i.e.

a) push button fixed; b) pull switch fixed;

c) push button portable;

d) pull switch portable.

This standard also gives guidance on automatically-activated trigger devices. For the requirements and tests applicable to such trigger devices, references are made to appropriate ISO/IEC standards for fire alarm, gas alarm and intruder alarm system components.

This standard does not specify EMC emission or electrical safety requirements. These are covered by other standards.
