5.3 Installation lines
5.3.1 Ethernet
Network cable with RJ45 plug, Line requirement: CAT.5 E or higher quality.
5.3.2 Power supply of the reader
For short distances of up to 20 meters max., a single cable may be used for the power
supply for the reader and data line. A separate power supply cable needs to be pro-
vided for longer distances.
Recommended cable: 1 x 2 x 0.6 mm or 1 x 2 x AWG 24.
In case of long lines, the voltage drop due to line resistance will have to be consid-
ered.
5.3.3 Data line to reader/subterminal
Connection to the readers is performed via partyline, a 2-wire RS-485 interface. For
this connection, you may choose a star topology or a bus topology.
No further signals or voltages may be transmitted via the data cable to the reader,
for example door-opener activation, door-frame contact, etc. (exception power sup-
ply up to a line length of 20 m).
The shielding of the data line is generally connected on both sides.
The complete bus network (master lines and stubs) may be up to 1,200 m long. One
stub must not exceed 100 m.
Line requirements:
Shielded line with twisted wire pairs. Cables with wire diameter from 0.25 mm
2
to 1
mm
2
can be used.
Recommended cable:
CAT.5 S/UTP 4 x 2 AWG 24 or AWG 22 (according to EIA/TIA568).
5.3.4 Line to the door opener, the door opener key, and the door contacts
Line requirements: Cable diameters from 0.5 mm to 0.8 mm.
Recommended cable: CAT.5 S-UTP 4 x 2 AWG 24 or AWG 22 (according to EIA/
TIA568) or higher.
5.3.5 Coaxial cables to registration units
Registration units are connected to the access manager via coaxial cables The coaxial
cable transfers the HF signals from the RFID antenna, keyboard data and trigger data
for the optical and acoustic signal generators.
Line requirements: Coaxial cable 50 ohms, type RG174/U.
Maximum cable length: 30 m
Recommended cable length: < 10 m
5.3.6 Line to the Wiegand reader
Line requirements: Shielded line 6 x 0.6 mm (0.34 mm
2
) or 6 x 22 AWG
Maximum line length: 10 m
Length and technical design of the line must comply with the requirements speci-
fied by the reader manufacturer.
