3.1 Functional description and components
3.1.1 Function
The comfort handle functions as a door latch, handle
lever monitor and visual LED status display. A 40mm
semi-cylinder to DIN 18 252 serves as the master key.
This can be used to open the handle in an emergency.
If the lever handle is closed, the latch mechanism inte-
grated into the comfort handle locks automatically.
The handle can be incorporated into the CMCIII
system. This requires a CMCIII Access Control
(DK7030.202) which is attached near the door in
conjunction with a base system. An example of a
base system might be a CMCIII Processing Unit
(DK7030.000), a CMCIII Processing Unit Compact
(DK7030.010), a Rittal IoT Interface (SK3124.300)
and a Rittal PDU (DK7979.xxx, except PDU basic). In
such cases, the handle can be released via the base
system or using additional optional systems such as a
coded lock (DK7030.222/.223) or transponder reader
(DK7030.232/.233). The comfort handle has an identi-
fier enabling it to be detected automatically by the base
system.
Alternatively, the opening of the comfort handle can
also be controlled via an external controller. In such
cases, the external controller provides both the supply
voltage and the signal for opening the lever handle via
the PLC interface.
Note:
In the following text, the designation
"CMCIII Processing Unit" refers to the
"CMC III Processing Unit" variants and also
to the base systems. All text passages that
apply only to a specific variant are identified
accordingly.
