26 Group control
Group control (see Fig. 3)
Group control applies for the individual devi ce and also for
all the devices connected via the data line (D and –). It is
activated by closing an external switch (see Fig. 1, Pos 2).
The devices connected via the data line are divided into
"master" and "slaves". The control module which initiat ed
group control is automatically the master. The outputs o f
all the devices deliver the output signal specified by the
master. The functions set on the master are adop ted by
the slaves, except for reset and self-test. The master a nd
slave can be operated by all the pushbuttons.

Ending group control

Group control is ended by placing the switch 2 on the
master in the "off" position. If there is a faulty signal
transmission between the master and slave, the connecte d
"slaves" switch off and return to individual control.
