1+n technology
Configuration
The wire-saving 1+n system is based
on an installation with a common
core and a call core ãn“ for each
user which links the bell button at
the front door directly to each in-
house telephone. Using these two
cores, all the functions are imple-
mented, i.e. ringing, speech, door
release and switching functions. Up
to door 8 door stations can be oper-
ated in parallel without the need for
any further accessories.
At each in-house telephone, a storey
call button can be connected which
allows direct calls to be placed to
the apartment door. Actuation of
the door release always takes place
for the door station from which the
door bell was pressed. There is one
speech channel available within the
1+n system; The number of speech
channels can be increased by adding
further controllers.
In the plans, the joint core is laid
to terminal 1 and the calling core
ãn“ to terminal 7. Both cores must
be routed within the same cable.
Terminal 7 is supplied with power
in its idle status via the call button
module with direct voltage. As long
as the call button remains depressed,
the voltage continues to rise to its
full value.
No programming is required for the
basic functions ringing, speech, door
release.
Mounting, installation and servicing
work on electrical devices may only
be performed by a suitably qualified
electrician. Failure to observe this
regulation could result in the risk of
serious damage to health or fatal
injury due to electric shocks.
• When working at the device,
observe the remarks relating to
mains cut-off.
• Observe the DIN EN 60065
standard! When establishing the
electronic connection, observe the
requirements of VDE 0805 or
EN 60950.
• The building installation
must
include an all-pole mains switch
with a contact separation of at least
3 mm.
• Ensure maximum fusing of 16A for
the mains connection in the building
installation.
• When planning large-scale
(complex) systems, the distributor
space required for the switch panel
mounting devices must be taken
into consideration in the distributor
planning process.
• No external voltages >30 V AC/DC
may be applied to system users.
Devices with 230 V connection
In accordance with DIN VDE 0100
part 410, section 411.1.3 attention
must be paid to ensuring a safe
separation between system lines and
the mains voltage; i.e. system and
mains cores must not be permitted
to touch! The system line cable
(extra-low safety voltage) must be
stripped back by the minimum pos-
sible.
