mini B) or configuration only (RS232).
Ground
Earth/ground connection
Battery
12 V battery, 1.2 Ah, is connected to terminal
block C. (Please note! Not connected ex works!)
Slot for GSM or LTE interface PCB
An interface PCB can be retrofitted here to con-
nect the dialling unit via GSM or LTE instead of a
landline (on A/B). In the AT6-GSM, AT6-4G, AT6-
GSM Mini and AT6 4G-Mini models, the circuit
board is already pre-assembled. (Please note!
A SIM card, which is not included, is required to
operate an interface PCB. Before modifying the
dialling unit, disconnect it from the mains and
from the battery!)
overvieW of the At6 diAlling unit
Telephone line (a/b)
Connection for trunk line (landline or exten-
sion of a telephone system) optionally via
RJ12 socket or terminal block A. (Please note!
Connection must also be secured for one hour
in case of power failure)
Bus unit
Requires four wires to transmit power, voice and
data. Here, up to six bus units are connected to
the same bus via the travelling cable. (Please
note! Observe the maximum power length for
the respective cable diameter)
Relay
Relay 1 and 2 (on terminal block E) can be
programmed independently of each other. Cf.
chapter "Relay function".
Optional inputs and outputs
There are a 12 V output, 2 configurable inputs
(filter, LMS message, emergency call button, call
delay), an output for the alarm horn (200 mA
max.) and a supply output for the emergency
light (500 mA max.) on terminal block D.
Power connection
The supply voltage (via terminal block F) of the
dialling unit must be fed through an all-pole
mains switch in accordance with EN81-20.
(Please note! The ground connection cable must
have a cross-section of at least 1.5 sqmm)
