Note:
The frequency of maintenance checks could vary depending upon local codes and standards and
the environment of the installation.
Caution:
While a VESDA Zone is isolated, no fire warnings will be issued by the VESDA VLP detector
and any fire will go undetected. Prior to any maintenance or testing:
l
Inform appropriate supervising authority about the risk associated with isolating a VESDA Zone.
l
Check to see if the VESDA VLP detector is also being used by third party
l
Ensure that any ancillary devices dependent on the VESDA VLP detector are enabled by the isolation
before work is begun.
Attention :
Lorsqu'une zone VESDA est isolée, aucun avertissement de feu ne sera émis par le détecteur
VESDA VLP et aucun incendie ne pourra être détecté. Avant tout entretien ou essai :
l
Informez l'autorité compétente du risque associé à l'isolement d'une zone VESDA.
l
Vérifiez si le détecteur VESDA VLP est également utilisé par une tierce partie.
l
Vérifiez que tous les équipements auxiliaires dépendants du détecteur VESDA VLP sont activés par
l'isolation avant le début des travaux.
