Control
Controller inputs function on a short to ground basis.. Any mechanical button (not a switch) will
activate the controller after a short press. One end of the button should be connected to the controller
input, and the other should be grounded ((-) of 12V). All the above diagrams show this solution.
You can also run the controller with other elements or devices, including motion sensors. Motion
sensors can be found in two versions: a voltage of 230V voltage and a voltage of 5 or 12V. Do not
connect the sensor directly to the input of the controller, because, especially in the case of 230V
sensors, it will cause (at best) incorrect performance of the controller, and at worst the controller can
be completely damaged.
Before mounting the sensors, set their parameters. The most important is the length of the
impulse (the time for the sensor to start), which should be set to a minimum and should not exceed
15 seconds (preferable time about 1-5 seconds — this should be checked before purchase). The
second parameter which can be set on the sensor is the sensitivity and range of the sensor. This
parameter should be set experimentally in order to enable a steady connection at the proper time.
In some sensors you can choose between various modes of operation. The triggering mode should
be turned off, because in this mode the sensor provides the impulse continuously when someone is
within its range - and the impulse becomes too long in respect to the requirements of the controller.
Sensors operating at 230V network require the use of relays to separate the 230V circuit from
the controller inputs. Low voltage sensors will almost certainly need a special adapter, matching the
sensor signal to requirements of the controller. The following diagrams and descriptions explain how
to connect the most common types of sensors. If you need to use a different type of sensor, please
contact the manufacturer to establish how to connect the sensor.
We recommend that buttons (such as door bell ones) are installed on the top and bottom of the
stairs, besides motion sensors,.
Motion sensors with a voltage of 230 V
A typical motion sensor (230V) is
a standard size module and is con-
nected to the installation box. It has
regulatory elements (time, sensitivity,
etc.) and usually three contacts for
wires. Two are plugged into a 230V
network, and the third wire is used to
power the receiver (the lamp) and is
marked with an appropriate symbol.
Before installing the sensor, carefully
read the instructions.
Some motion sensors have a built-in additional twilight sensor. Depending on the sensitivity set-
tings it can be inactive in strong light. Thus, illumination of the stairs does not turn on during the day.
However, this may cause problems - if it rains, the twilight sensor will lighten the stairs. By adjusting
the sensitivity, you can try to prevent this. We can recommend our 230V sensor CRN-5491, modified
to work with our controller:.
The next diagram is one of a typical motion sensor (230V) connected to the controller. Relays
must be used! Relay coil voltage must be set at 230V, because this voltage is supplied from the
motion sensor. Connect input 1 or 2 and (-) of 12V to the contacts of the relay NO (normally open)
and CO (common),. We recommend the assembly to be done very carefully. If the connections are
made erroneously, the controller will be damaged.
