Checking networking
After complete construction of the network, a failure message must be generated on
each of the systems that are networked in order to check data transmission. This is
displayed at the Master if functioning correctly.
For networked systems, a failure message can, for example, be generated by
actuating the blocking switch.
L
CAUTION
Faulty release due to activated system!
Checking networking using the blocking switch can result in a faulty release and
thereby cause injuries and property damage.
● Only use the blocking switch to check networking if there are no red LEDs lit up
and there is no fire alarm shown in the display.

Reading out the state of the respective systems
The display for the current state of the system is at the Master (active extinguishing
system DET-AC III Master or EFD III). The messages of the networked devices with
the identification
“Z2”
to
“Z5”
are shown on the Master display.
