Alarm systems - Intrusion and hold-up systems - Part 8: Security fog device/systems

IEC 62642-8:2011 specifies the requirements for security fog systems as a part of an I&HAS. It covers application and performance and also gives the necessary tests and trials to ensure efficiency and reliability of such obscuration devices. It also gives guidance on the criteria for design, installation, operation and maintenance of security fog systems.

Systèmes d'alarme - Systèmes d'alarme contre l'intrusion et les hold-up - Partie 8: Systèmes/dispositifs générateurs de fumée

La CEI 62642-8:2011 spécifie les exigences relatives aux systèmes générateurs de fumée dans le cadre d'un système d'alarme contre l'intrusion et les hold-up (I&HAS). Elle couvre l'application et les performances et fournit également les essais et mises à l'épreuve nécessaires pour garantir l'efficacité et la fiabilité de tels dispositifs d'obscurcissement. Elle donne par ailleurs des lignes directrices sur les critères de conception, d'installation, de fonctionnement et de maintenance des systèmes générateurs de fumée.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
