LOKUS A-4 – STANDALONE RF CONTROLLER /
RECEIVER
The Lokus A-4 is a controller with built-in RF receiver. It is
designed for residential and business buildings, shops, etc.
In various operation modes, the controller allows access for up to
34 users (1 master 34 user buttons on remote
controllers). The entire set-up procedure is carried out with
master remote controller Remo. User Remos can either be
registered or deleted. The controller signals normal operation
with flashing red and green LED.
It can also be used as a
Wiegand 26-bit reader, if needed.

Power supply
The controller needs 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 the 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
least 0.22mm
2
. 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 the power supply and
controller should not exceed 50m.
Take into consideration that a 0.22mm
2
cable has a resistance of
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
2
or more should be
used wherever possible.
If the load is, for example, 0.5A (with el. strike) then, on the
0.22mm
2
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 installation site. The proximity of
metal or EM interference significantly reduces reading distance.
Installation of Lokus A-4
A special holder, provided with the controller, is needed for its
attachment to the wall. Two screws are enclosed in the box. After
the holder has been affixed, put the controller onto the holder
and press – after you hear the click, it is fixed.
If you want to remove the controller from the wall, put the
screwdriver under the controller’s casing (as close as possible to
the holder’s attachment points) and turn it gently.
If you will install two controllers closer than 50m from the place
where the remote controller will be used, than both controllers
can receive the code. Dont install the controller directly on metal.

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 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.
