INTEGRUS | Installation and Operating Manual | System description and planning
Caution: Turn the delay switches carefully
to a new position until you feel that it
clicks into position, to prevent that a
switch is positioned between two
numbers, which would result in a wrong
delay setting.
Note: When a master-slave configuration
is used for rooms which are always sepa-
rated, the delay switch positions can be
determined per system and the delay
caused by transmission from master to
slave transmitter can be ignored.
Figure 1.28, table 1.1, table 1.3 and table 1.4 illustrate
the calculation of the extra master-slave signal delay.
