Activating auxiliary devices with Tekna S Plus monitors:
Continued overleaf
Auxiliary device activation requires the use of an SAR-12/24 relay unit. If the feature is shared by all monitors,
connect their A1 terminals; if, however, each monitor has its own feature, use an SAR-12/24 relay for each one
and do not connect their A1 terminals.
This function is activated when button
is pressed on the monitor at any time and regardless of the position of the
handset.
The most common applications are activating the stairway lights and opening a second door.
