WARNING
Danger of reignition if devices are not shut down!
In order to prevent reignition, it is imperative that there is an energy shutdown of
the devices within the protected enclosure when the extinguishing system is
released.
● Use the floating contacts (Fig. 19/1 to 3) for the device shutdown that is to be
realized by the operator.
● If shutdown upon release is not guaranteed, it is necessary to make sure that a
manual fire fighting or shutdown measure, which
– prevents reignition, is completed within the hold time of the extinguishing
concentration,
or
– that an automatic shutdown of the devices is completed in order to prevent
reignition.
