Jantar REX K-1-7 Manual

REX K – STANDALONE OR ACCESS CONTROLLER
The Rex is a controller with built-in proximity card reader and
keypad. It is designed for residential and business buildings,
offices, shops, etc. In various operation modes, the controller
allows access for up to 500 users (1 master card + 500 user cards
or codes). The controller can have 125kHz or 13.56MHz reading
frequency.
As a standalone controller, the entire set-up procedure is carried
out with master card or code. User cards and codes can either be
registered or deleted.
As an access controller, the entire set-up procedure is carried out
with the software.
The controller signals normal operation with lit red LED. It can also
be used as a Wiegand 26-bit reader.

Power supply
The controller need's external power supply to operate. The Spider
W40 power supply is sufficient to power two controllers and two
12V electric strikes or two 12V magnetic locks (0.5A). If you use it
as a standalone controller and low consumption electric strike
(0.25A) you can use power supply Spider W5.
Voltage drops and cable signal interferences
When you connect the controller, use cable with a diameter of at
2
least 0.22mm . If the cable length exceeds 25m, use one twisted
pair of UTP cables for the positive (+) pole and one for the
negative (-) pole. The cable length between power supply and the
controller should not exceed 50m.
Take into consideration that a 0.22mm
approximately 9 ohm per 100m. The power supply at the end of
cable should be a minimum of 9V. If you are using el. strike, it is
highly recommended that the voltage drop is calculated. At greater
distances, a thicker cable of 0.5mm
wherever possible.
If the load is, for example, 0.5A (with el. strike) then, on the
2
0.22mm cable voltage drop will be 4.5V at 100m. For the device
with 60mA consumption, the voltage drop is 0.5V.
Reading distance depends on where the controller is installed. The
presence of metal or interferences can significantly reduce the
reading distance. DO NOT install the controller directly on metal
surfaces and/or cover it with a metal cover.
It is not recommended to install controllers closer than 30cm
from each other in any direction. Otherwise, it may result in
inaccurate readings or, indeed, in the controller not reading at
all.
For the Rex K-3-7 to comply with EMC directives (CE), you
have to put ferrite core on the cable as close to the Rex as
possible, making two turns!
Inputs, outputs and environment
Inputs:
Inputs are realized with opto-isolators. The input is active, when
pulled to ground with an open collector transistor or mechanical
switch, which is connecting the input pin of the controller to the
Ground.
Outputs:
Output has a pre-installed protection diode for an inductive load. It
is also protected from current overload. The best way is to use a
0.25A el. strike or a 0.5A el. magnet, which has to be connected to
the same positive pole (+) as the controller. Connect the negative
pole (-) to the door strike output (wire 3). When the output is
active it is pulled to ground. This can be changed with function 5 –
negate output (for el. magnet).
Environment:
The controller has IP65 protection, but you must assure good cable
joints, protected against moisture, otherwise corrosion may
damage the controller. Damage in such cases is not covered by the
warranty.
Rex K-1-7 reading range:
The controller has a program algorithm that, at power start, sets
parameters based on the installation environment, so as to ensure
an optimal reading range. DO NOT install the controller directly on
metal surfaces and/or cover it with a metal cover; it may stop
working/reading. If you plan to test the controller and move it onto
different surfaces, then you have to reset it (power off/on) on each
surface.
