•
Operation using the primary multiplex connection S2M
is not possible.
• The AT 2000 TSN ISDN communicator for danger alarms
must be connected to the S
0
bus as the first device.
With this connection, it is possible for the
AT 2000 TSN ISDN to send a message even in the event
of tampering or damage to the bus wiring.
ISDN PTP
•
The "constant monitoring" layer 1 feature is present by
default for system access.
• The max. cable length from network termination NT via
the UAE 8/8 box to the TK system or to the end unit is
1000 m.
ISDN PMP
• The "constant monitoring" layer 1 feature is also
required with a multi-system connection.
•
The max. cable length between network termination
and TK system or end unit is 150 m.
GSM transmission
•
The GSM network can also be used alone for a message
transmission (without ISDN).
• For application according to VdS, only backup path
transmission from D1 to D1 or D2 to D2 is permissible.
Antenna planning
•
The antenna selection depends on the measured field
strength. The antenna and the cable must be selected
so that the measured attenuation on the AT 2000 does
not exceed -87 dB.
•
If the antenna is placed near an automatic fire or
intrusion detector, the distance of the antenna to the
detector must be at least 1 m.
•
We generally recommend the use of a radiator (rod
antenna for exterior and interior areas). If the reception
level implemented with a radiator is insufficient, beam
antennas (planar or exterior antennas for exterior and
interior areas) should be used.
• With the installation of antennas outdoors, the relevant
DIN VDE provisions, especially DIN VDE 0845 part 1 and
VdS 2311 appendix F (protection against lightning)
must be adhered to! The ground connection isolator
and the lightning protection set (optional) are designed
for this.
•
Make measurements precisely where the antenna will
be mounted. The measurement results must remain
stable for a period of 10 minutes.

• If necessary, the pre-configured cables must be
shortened in order to avoid unnecessary attenuation.
• The Aircom Plus cable must be used if the low-
attenuation standard cable achieves no level better
than -87 dBm.
• Applications must strictly adhere to the bending radius
of at least 55 mm.
