Alarm systems – Part 2: Electromagnetic compatibility – Immunity requirements for components of fire and security alarm systems - Edition 1.0
 N 62599-2

Annotation

This part of IEC 62599 for immunity requirements applies to the components of the following alarm systems, intended for use in and around buildings in residential, commercial, light industrial and industrial environments:

– access control systems, for security applications;

– alarm transmission systems2;

– CCTV systems, for security applications;

– fire detection and fire alarm systems;

– intruder and hold-up alarm systems;

– social alarm systems.

The tests and severities that should be used are the same for indoor and outdoor applications of fixed, movable and portable equipment.

The levels do not cover extreme cases, which may occur in any location, but with an extremely low probability of occurrence, or in special locations close to powerful emitters (e.g. radar transmitters).

Equipment within the scope of this standard should be designed in order to operate satisfactorily in the environmental electromagnetic conditions of residential, commercial, light industrial and industrial environments. This implies particularly that it should be able to operate correctly within the conditions fixed by the electromagnetic compatibility levels for the various disturbances on the low voltage public supply system as defined by IEC 61000-2-2. The immunity tests in this standard only concern the most critical disturbance phenomena.
