These motion sensor-activated LED stair lights switch on automatically to light up your stairs when
you reach the top or bottom step.
Control unit SCR2 switches each step individually, giving a sweeping motion up or down the staircase,
then turns off the lights together, by gently fading out.
This document explains how to install and operate your control unit.

Incorrect connection of the motion sensors, lights and the power supply can damage the controller!
DIY tips and safety advice
•Personal protective equipment. Make sure that you are equipped with suitable and
sufficient personal protective equipment. This could include eye protection, face mask,
protective overalls, safety footwear and gloves.
•Consider your safety! Think about the potential risks and dangers of the work and the
steps you should take to avoid them.
•Ensure that the work area is sufficiently illuminated.
•Check that the tools you will be working with are in a good operating condition.
Electrical work safety advice and tips
•Ensure that a 220-240 V AC power source is available.
•An appropriate protective device e.g. fuse or miniature circuit breaker should be
installed at the consumer unit. We recommend a 6 A type B MCB for this purpose. If
the supply circuit to the stair lights is not dedicated, your electrician can advise on
protection arrangements.
•Before undertaking any electrical connection work, ensure the circuit is isolated at the
consumer unit by turning off the MCB and, if practicable, locking it in the OFF position.
Working live can cause injury and can damage components of your Intelligent Stair
Lighting.

1) Decide on the location for your control unit and power supply. Both are designed to fit on a
DIN rail (optional) for ease of installation.
2) Choose the instruction that matches your lights.
a) LED strip lights with profiles: Attach the profile to the stairs, according to your chosen
profile. Note that profiles can be cut shorter if necessary.
Profile type
Standard
Angular
Recessed Slim
This profile can be fitted
underneath treads or to
risers, depending on your
particular installation
requirements.
End cap adds 1.5 mm in
length to each end of the
profile.
This profile can be fitted
underneath the bullnose of
each stair or in the corner
where the treads and risers
meet.
End cap adds 1.5 mm in length
to each end of the profile.
This profile is designed to sit
in a groove underneath the
treads of an open staircase.
Make a channel of the
required depth and length
using a router or other
suitable tool.
End cap adds 15 mm in length
at the top and 8 mm on the
under-side to each end of the
profile.
If necessary, cut LED strips to length. N.B. only cut LED strips where indicated with the scissors
(✂) symbol
All profiles are fitted by removing the diffuser, drilling the aluminium at suitable points
(depending on your installation site) and screwing the profile to the stairs.
Important note!
While cutting, drilling or making recess for the screwheads for the profiles, a small amount of
metallic chip and debris will remain in the profile. This can cause small short circuits over
days/weeks/months and can result in the LEDs on the strips to fade out or stop working.
Therefore, it is very important to thoroughly clean the profiles, before placing the LED strips
inside.

c) Surface-mounted/ Flush-mounted spotlights: The spotlights are suitable for surface-mounted
and flush-mounted installation
The surface-mounted frame can be removed if the lights are flush-mounted.
The dimensions of the surface or flush-mounted can be seen on the diagrams below.

3) Position the motion sensors at the top and bottom of the stairs so that the person entering the
staircase crosses the beam. The height of the motion sensor can be chosen to suit the installation
site. Low sensors are discreet; placing sensors higher allows pets to pass underneath the beam so
that they do not activate the lights.
We recommend installing the motion sensors on the baluster side and directing the signal
towards the wall. The motion sensors are designed to have a range of 1 m –1.3 m, though this
can depend on factors such as temperature and humidity. Special attention should be paid
when positioning the motion sensors to ensure they are not triggered while walking past the
stairs. Fit your sensors according to their type:
Flush mounted
Surface mounted
Baluster mounted
Prepare a suitable recess and install
the back box using screws. Clip the
sensors in place on the front of the
box. The face plate can be painted
or covered over as long as the hole
in the centre remains uncovered so
the beam can operate properly.
Dimensions:
●Faceplate: 7.2 cm
●Depth: 4.8 cm,
●Tube 6.3 cm
Stick your sensors in place using
double sided adhesive tape or glue.
Dimensions:
●Height 4.5cm x width 1.5cm x
thickness 1.6cm
Insert each sensor into a recess of
the correct diameter and fix it
securely using adhesive tape,
glue, or an alternative method of
your preference.
These sensors can be filled over
as long as the hole in the centre
Page 8of 19
remains uncovered so the beam
can operate properly.
Dimensions:
●Diameter 4cm, thickness
1.4cm
Motion sensors are interchangeable so it doesn’t matter which goes at the top and bottom of
the stairs. We provide 10 m of cable with each motion sensor, giving you flexibility on how you
install your stair lights. These three-core cables can be extended if required, by making an
appropriate joint.
Incorrect connection of the detector wires may damage them as well as damage the
controller.
4) Once motion sensors have been fitted to the staircase, they should be connected to the control
unit.
This action must be performed whilst the unit is disconnected from the power supply!
The detector placed at the top of the stairs should be connected to the top of the controller in the
"GÓRA / UP" section, while the detector placed at the bottom of the stairs should be connected
in the "DÓŁ / DOWN" section. Note that motion sensors are supplied with tails of three-core
cable, coloured red, black and green. For the first motion sensor, insert each core of the cable
into the terminal of the corresponding colour (with due regard to which terminals are for the top
sensor and which are for the bottom) and tighten the terminal screw to grip the wire securely.
After connecting the first motion sensor, test it by temporarily connecting the power supply,
according to instructions 5) to 8)
OPTIONAL: If a twilight sensor is used (the sensor is an additional option) its coloured wires should be
connected to the corresponding, coloured slots of the LUX section.

This action must be performed whilst the unit is disconnected from the power supply!
OPTIONAL: If the stair lighting set is connected to the switch on the wall (remember that for the set to
function properly it must be a bell switch (also known as momentary switch or push switch), connect
it in the place indicated in the photo below.
This action must be performed whilst the unit is disconnected from the power supply!
5) Using two core flex, connect the power supply unit (DC 12V - 24V) to the control unit, matching
the + and –terminals on both units. Note that:
Page 10 of 19
•terminals on the control unit are located on the top left, labelled + and -
•terminals on the power supply unit are located on the top right, labelled V+ and V-.
There are two sets of terminals; only one V+ and one V- should be used
6) To test your installation, you need to connect one light to the control unit. Note that only the
linear LED light strips supplied by us come with tails of two-core cable, coloured red and black.
Insert the black wire into the terminal at the bottom of the control unit marked “1” and tighten
the screw to secure the wire. Insert the red wire into the terminal marked + on the top of the
driver and tighten the screw to secure the wire.
MINUS (-)
Connect the negative terminal of each LEDs to these numbers.
The numbering from 1 to 20 corresponds to the steps from the bottom of the stairs.
PLUS (+)
Combine all the positive terminals together. Then connect combined positive
(common plus) to the "+" in the upper section of the controller.
