NOTICE
Faulty release due to removal of the blocking!
Premature removal of the blocking can result in a faulty release and thereby cause
property damage.
● Do not stop blocking the system until there are no red LEDs lit up and there is
no fire alarm shown in the display.
5.3
Installation and commissioning of additional electrical devices
Following proper installation and commissioning, additional electrical devices can be
connected to the system.
NOTICE
Damage due to alarm release!
The alarm can be released during installation/start-up of an additional electrical
device. This can cause significant property damage.
● Shut down external system controllers (e.g. activation of further extinguishing
systems or transmissions via floating contacts) prior to connecting additional
electrical devices.
● Block the system prior to the function test for additional electrical devices. To
this end, switch the blocking switch to “Agent disconnect [blocked]”. The yellow
“Failure” LED lights up continuously.
● Check that no alarm message (red LED “Extinguishing system triggered”) is
displayed prior to removing the blocking. The extinguishing process is other-
wise initiated immediately.
