Caution: While a VESDA Zone is isolated for maintenance, no fire warnings will be issued by
the detector and any fire will go undetected. Prior to any maintenance or testing:
Inform appropriate supervising authority about the risk associated with isolating a
VESDA Zone.
Check to see if the detector is also being used by third party.
Ensure that any ancillary devices dependent on the LaserSCANNER detector are
enabled by the isolation before work is begun.
