Technical Information - DETEWE OpenCom 510 User Manual

The "Doorline" actor can be op-
■
erated only when the speech
channel is open at the same
time.
The "Doorline" intercom system
■
can be connected to any a/b
port. However, you can use only
one "Doorline" with the
OpenCom 510.
For details on installing and config-
uring the "Doorline" intercom sys-
tem, refer to the product user guide.
The intercom system should be in-
stalled by qualified personnel only
as sensor/actor contacts will need to
be connected for this procedure.

Technical Information

The a/b ports have been imple-
mented as RJ45 sockets. Each of the
devices listed above can be con-
nected to the a/b interface by means
of a two-wire 1:1 cable.
A two-wire cable connected to an
a/b port can be up to 6500 m long,
provided it is a 0.6 mm twisted-pair
cable, or up to 3000 m if a 0.4 mm
twisted-pair cable is used.
The 50 Hz/40 V AC ringing voltage of
the eight interfaces is supplied by
the interface card.
