Installation
It is recommended not to install the device on metal surfaces, as this
may reduce the quality of communication. If placement on a metal
surface is necessary, use a reinforced plastic mounting base
(not included with the device).
Wiegand connection
The length of the communication line through the Wiegand interface
must not exceed 328 ft (100 m). This interface is not immune to
external sources of interference. We do not recommend running it in
parallel with power cables or near other sources ofinterference
(fluorescent lights, etc.). It is recommended that the Wiegand link be
run at least 1.64 ft (0.5 m) away from any power cables. If the link
length exceeds 16.4 ft (5 m), a UTP 5E cable is recommended.
OSDP connection
This device's OSDP uses an RS-485 interface designed for long-
distance communication. The communication cable connecting
OSDP-enabled readers can run up to 3,280 ft (1,000 m) in length.
The OSDP communication line should be laid as far away as
possiblefrom power cables and electric lights . A UTP 5E or FTP 5
twisted pair cable should be used as the OSDP communication line. If
possible, ground the shield at one end. To ensure reliable system
operations, it is best to use one power supply for the controllers and a
separate power supply for the actuators. The power supply line wires
for the reader should be kept as short as possible to avoid a
significant voltage drop across them. After cabling, ensure that the
power supply voltage to the reader is at least 12 VDC with the locks
switched on.
