Detection and control via two wires
In local security networks, detection and control functions
are performed via the LSN line. This means additional
primary lines in the control panel are not required for
control procedures.

Optional KR 100 LSN relay module for LSN expanders
The KR 100 LSN relay module for LSN expanders is intended
for use in the NNK 110 LSN and NVK 100 LSN.
The KR 100 LSN is installed if the high power requirement
of the connected control elements results in these
becoming impossible to actuate directly by the LSN
expanders, or in order to enable zero-potential switching.
Up to four KR 100 LSNs can be installed per NNK 110 LSN
or NVK 100 LSN. One solder distributor is supplied per two
KR 100 LSNs.
