Mounting guidelines
The reader is suitable for indoor and outdoor use. Mount directly on the wall or use a "standard f.m.
socket". The electronic unit that is completely protected against humidity is inserted in the back of
the housing and locked into position with the housing front (replaceable). Communication with the
AC central control unit is via the moulded (fixed) 12-core connecting cable.

In masonry with S6 plug:
E.g. semi-circular wood screw with slot 3.5 x 60 mm
-
In wood, depending on type: Semi-circular wood screw with slot 3.5 x 45 to 3.5 x 60 mm

When mounting, feed the connecting cable, if possible, from the back through an empty pipe
allowing sufficient spare cable.
To mount, lift the housing front at the bottom and unhook at the top.
The housing back has two 60 mm boreholes for wall and f.m. sockets. To fix securely, use screws that
are suitable for the mounting surface in question.

Fillister head screw M3 x 30 mm (min.) with washer
On the standard s.m. socket
Semi-circular wood screw with slot 3.0 x 40 mm and washer
(see 4.1). Choose the correct screw length for
the mounting surface.
In order to operate and read the keypad optimally, install the reader at a
above the floor.
When used outdoors, do not expose the reader to the weather. If necessary, use the plastic shield
(weather/view) Item no. 023501.
When installing the housing back,
remove the electronics to avoid damage.
For additional fixing, the third borehole can be used
height of 130 to 140 cm
If the reader is to be used outdoors,
the cable bushing must be sealed

When mounting on an f.m. socket or
on a cavity wall, install the socket so
that the fixing holes are horizontal
(see illustration).

Interfaces
The reader has the interfaces
and
that can be used alternatively. When started
up, the reader automatically identifies the interface that is in use.
To ensure reliable functioning, ensure that a possible extension of the 6 m connecting
cable does not exceed 40 m. A JY(ST)Y 6x2x0.6 mm cable can be used for extension
purposes.
The reader can be used remotely at a distance of max. 1200 m. We recommend
using a Cat 5 connecting cable.
If the reader is the last user on the RS-485 module bus, a distributor with a 120 Ohm
terminating resistor (from A to B) must be installed in front of the reader.
For further information, refer to the description of the corresponding central control
unit.

RS-485:
A plug has been soldered to the cable of the reader at the factory especially for test and
premounting sets. For the final installation, it usually has to be cut off.

Synchronization
(RS-485)
In order to prevent densely packed readers from affecting one another, they must be connected to
one another via the "Synchronization" line (black). Up to 4 readers can be synchronized in this
manner.
Synchronization is required at a distance of
(approximate value).
The transponder that is identified first has priority during the read process. The other readers
involved are inactive. After a period of 5 sec. they are reactivated.
