AS-225D
12-channel
cascade controller
The AS-225D controller is designed for cascade control of
12÷24 V staircase lighting, which allows to achieve the effect of
light following a person walking up or down the stairs.
»Control of cascading multi-point lighting system;
»The ability to set the number of controlled light points (from
3 to 12);
»The ability to connect controllers in series to increase the num-
ber of controlled circuits;
»Additional control inputs:
permanent light switching (for example during houseworks);
light switching lock (for example brightness sensor signal);
»Control of light using a variety of setters including bell buttons,
motion sensors, optical barriers, pressure sensors, etc.
»Adjustable "soft start"feature – soft brightening and dimming
of lighting;

Do not dispose of this device in the trash along with other waste!
According to the Law on Waste, electro coming from households free of charge and can
give any amount to up to that end point of collec� on, as well as to store the occasion of
the purchase of new equipment (in accordance with the principle of old-for-new, regard-
less of brand). Electro thrown in the trash or abandoned in nature, pose a threat to the
environment and human health.

The "soft start"feature requires dimmable light
sources.
»"Night light"feature – the ability to set the brightness level
when off, so that the stairs are never completely dark;
»Installation of the controller on a DIN rail;
»Built-in thermal protection.
The operating parameters of the AS-225D controller are set
using the knobs on the front of the unit. The operating status is
indicated by LEDs,
Operator panel

Func-
tion Description
OUT
Set the number of controlled output circuits.
Setting range from 3 to 12. The first controlled
circuit is always OUT 1 (when the DOWN button
is pressed, the cascade will start from OUT 1). The
setting of this knob determines which controlled
circuit will be the last So if, for example OUT is set
to 9, the last output to be controlled will be OUT
9 (when the UP button is pressed the cascade will
start from OUT 9).
TIME
Switch-on duration of a single output.
Setting range from 3 to 30 seconds.
Warning! This is the minimum switch-on duration
of the output. If the UP or DOWN input is trig-
gered for a long time, it will increase the output
switch-on duration accordingly.
DELAY
Delay between switching on subsequent outputs
of the controller. The setting range (0÷100%) re-
fers to the set time of switching on of the output.
So if, for example, the switch-on duration of a
single output is set to 15 seconds, then:
Delay 0 %: The next segment will switch on as
soon as the previous segment is switched on.
Delay 50 %: The next segment will switch on 7.5 s
after the previous segment is switched on.
Delay 100 %: The next segment will switch on 15
s after the previous segment is switched on.

OFF
LEVEL
Brightness level in the off state. Setting range
from 0 to 25 %. This parameter enables the "night
light" feature - setting a non-zero brightness level
will cause the lights to glow gently all the time,
and only when the cascade is triggered will they
light up to full brightness.
Warning! The "night light" feature should be
combined with an external brightness sensor
connected to the OFF input. Such will cause the
controller and the "night light" feature to work
only at the actual low brightness level.
LED signalling
U Controller power indication
OUT Output circuit power indication
OVER-
TEMP
Signalling that the acceptable temperature inside
the controller is exceeded.
Warning! The AS-225D controller is equipped
with thermal protection to prevent excessive
overloading of the output circuits.
If the temperature limit is exceeded, the pro-
tection starts to work and limits the maximum
brightness level first. It is only when the tempera-
ture continues to rise that the controller outputs
are completely disconnected.

light
State Description
Off Normal operation
Slow flashing
Warning temperature exceeded, output
brightness level limited to 1/2 the maximum
value.
Fast flashing Alarm temperature exceeded, output bright-
ness level limited to 1/8 the maximum value.
On Persistent exceeding of the alarm temperatu-
re, controller outputs turned off.
If the thermal protection is tripped, normal operation is
restored automatically as soon as the temperature falls
to a safe level.

Power
supply
Power supply of the controller
Warning! Maintain proper power
supply polarity as indicated on the
enclosure.
Warning! If the simultaneous load of
the controller exceeds 12÷16 A, con-
nect two independent power wires "–"
to the first and second terminal of the
controller and lead them to the power
supply unit.
+
DOWN Control
input
A short press on the DOWN button
starts the cascade moving from the
bottom to the top. The circuits will
be switched on starting from OUT 1,
OUT 2, OUT 3 and so on until the last
controlled output is reached. Each of
the outputs will be switched on for the
time TIME (set by the knob on the con-
troller). The delay between switching
on subsequent outputs is set on the
controller with the DELAY knob.
Warning! If the DOWN button remains
pressed the lights remain on for the
duration of the pressing. The shutdown
sequence of each output will begin
when the DOWN button is released.

UP Control
input
A short press on the UP button starts
the cascade moving from top to bot-
tom. The last circuit controlled will be
switched on first, then the penultimate
circuit, and so on until the first circuit
OUT 1 is reached. Each of the outputs
will be switched on for the time TIME
(set by the knob on the controller). The
delay between switching on subsequ-
ent outputs is set on the controller with
the DELAY knob.
Warning! If the UP button remains
pressed the lights remain on for the
duration of the press. The shutdown
sequence of each output will begin
when the UP button is released.
ON Control
input
Triggering the ON input causes simul-
taneous activation of all controlled
output circuits of the controller. The
circuits remain switched on as long as
the ON input is triggered. In this mode,
the operation of the DOWN and UP
inputs is locked.

- 9 -
OFF Control
input
Triggering of the OFF input (for example
by an external brightness sensor)
switches off all controlled output
circuits. The lights in this mode are
completely off, regardless of the OFF
LEVEL parameter setting. Operation of
the DOWN and UP buttons in this mode
is also disabled.
OUT1

OUT12
Output
circuits
Outputs for connecting light sources.
Pay attention to the order of connec-
tion and the power of the light source.
Connect the "–" wire of the lights to
the OUT terminals, and connect the "+"
wire directly to "the "+" of the power
supply (according to the installation
diagram above).
The maximum current of a single lamp
shall not exceed 4 A, while the total
current of all lamps switched on at the
same time shall not exceed 24 A.
Warning! Provide a power supply unit
of sufficient capacity to guarantee
proper powering of both the controller
and all operating sources. Overloading
the power supply usually results in a
power cut, which will interrupt the
controller operation.

Output
circuits
Warning! It is possible to split the
power supply of the output circuits to
several power supply units.
In this case, you should:
»divide the output circuits into a
required number of groups and con-
nect the wires ("+") of the group to
the chosen power supply unit,
»connect the power supply of the con-
troller ("+" and "–") to one of the po-
wer supply units,
»the wires ("–") of all power supplies
should be connected with each other
and with the terminals ("–") of the
AS-225D controller.
Starting another cascade while the previous one is run-
ning will not interrupt the work of the first one, but will
start the next one in the set direction. The exception
here is the situation described in the next comment.
If during the cascade execution the last light is already
switched on and at the same time an input (DOWN or
UP) is triggered at the end of the cascade, the control-
ler will interpret such action as the first person leaving
the staircase and therefore will not trigger the cascade
of lights in the opposite direction.
Cascade control

- 11 -
When the number of controlled output circuits exceeds
12, the system can be expanded by connecting several
AS-225D controllers in series. A sample wiring diagram is
shown in the figure below.
Example of cascade control
According to the above scheme, any number of control-
lers can be combined.
