CAUTION
Danger of injury from faulty release!
Checking the fire detector when the system is not blocked can result in a faulty
release. A faulty release may cause injuries and significant property damage.
● Block the system prior to checking the fire detector. To this end, switch the
blocking switch on the back of the system to the
Ⅱ
"Agent disconnect [blocked]"
position.
● Switch the blocking switch (Fig. 44/arrow) on the rear side of the system to
"Agent disconnect [blocked]". In this way the release mechanism for the propel-
lant cartridge is deactivated.
