Controller operation

The intelligent stair controller S19 Premium is the heart of the intelligent staircase LED WAVE lighting system. Its basic function is impressive, smooth lighting switching on for a specified time. In the standby mode of the controller, the lamps can be off or slightly illuminated. When activated by any stair sensor, the full lighting is switched on sequentially, lamp by lamp (LED WAVE). After the set lighting time, lights are automatically switched off or dimmed to the set backlight value.

Some other functions include: dimming, warning when the lights are to go off, prolongation of lighting, permanent lighting, operation of the Master lamp, blocking the lighting during the day.

The controller operation can be adapted to the user’s preferences by changing the configuration settings (18 parameters) with the use of built-in configurator (see the CONFIGURATOR tab).

The controller has 2 modes of operation: MAX and DAY, switched automatically by dusk switch.

The controller can support both dimmable and non-dimmable lamps. In the case of dimmable lamps, switching on and off of each lamp is smooth (gradual change of brightness), and in the case of non-dimmable lamps – sharp.

The direction of the LED wave depends on the place, where the controller activation is originated: it can go up (when the controller is activated at the bottom of the stairs) or down (activated  at the top of the stairs).

Basic properties and functions of the S19 stair controller:
  • Automatic switching lamps off after set time
  • Switching on/off style: successively lamp by lamp (LED WAVE)
  • True LED light wave, with the effect of “blur” (subsequent lamps may begin to gradually light up before the previous ones reach maximum brightness)
  • Adjusting the smoothness of dimmable lamps switching on/off (7 levels of smoothness)
  • Backlight of all lamps in standby mode
  • 2 user-configurable operating modes: DAY and MAX, automatically switched with built-in dusk switch or external device/switch/pushbutton connected to the DIS input
  • Warning function before the lights go off
  • MASTER lamp function for ceiling/wall lighting or handrails
  • Dimmer function (separately for MASTER lamp)
  • Light prolongation function
  • Permanent light function
  • Switching on/off of non-dimmable lamps
  • Built-in dusk switch + light probe for indoor or outdoor installation
  • 3 control inputs for connecting motion sensors and / or buttons
  • Possibility of cooperation with any Smart House installation
Impressive and smooth LED light wave

Sequential, smooth switching on/off of lamps with the effect of “blur”
Gradual, smooth brightening or dimming of each lamp. When switching on, the next lamps may begin to light up before the previous ones have reached their maximum brightness. The wavefront is brighter than its tail. The LED wave runs smoothly along the stairs – up, down or both directions from the mid-floor. Switching off is the opposite: subsequent lamps may begin to gradually dim before the previous lamps reach the set backlight value.

Light wave parameters

  • smoothness (a choice of 7 levels of the speed of changing the brightness of a single lamp – from a sharp change to a very gentle)
  • brightness
  • duration of switching on, lights-on and switching off phases
  • switching on/off characteristic (step type): accelerating, decelerating or with a constant step
  • switching off direction (the same as switching on or reverse)
LED light wave
Built-in dusk switch with light probe
  • Function: blocking of switching on lamps during the day
  • 10 brightness thresholds (selectable) for the light probe
  • Mounting of the probe: outside or inside in the area of the stairs (the controller is intelligent – it does not react to light which it turned on itself; this is an important advantage over external twilight switches, whose light probes must be installed outdoors, in a place not lit by artificial light). The light probe should be connected to the DIS input of the controller.

ATTENTION: Instead of the light probe, another device (e.g. a switch or astronomical clock) or potential-free output of any Smart Home system can be connected to the DIS input.

Hermetic light probe (sensor)
Built-in configurator

Possibility to configure up to 18 controller parameters:

  • Installation parameters: Number of lamps (3-19), Master lamp (none, dimmable, non-dimmable), Active inputs level (zero, one), DIS input (lock, unlock, flip, S1-S10 (brightness thresholds for the light probe)), extended input filtering (no, yes)
  • Dimmer parameters: Brightness (10% -100%), Backlight lighting (0% -90%), Master brightness (10% -100%), Master backlight (0% -100%)
  • Light wave parameters: Smoothness (0-7), Turning-on time (0s-24s), On time (0s-240s), Turning-off time (0s-24s), Step type (slows down, steady, speeds up), Off direction (backwards, compatible)
  • Warning function parameters: Number of warnings (0-7), Warning type (blink, piko, nano, micro, mile, rocking, swing), Warning time (0s-24s), Waiting time (0s-24s)

The installer sets the parameter number and its value using the buttons: SET. “+” and “-“. More information in the S19-Premium stair controller User Manual (see the DOCUMENTATION tab)

Sensor properties

DELTA is a digital diffuse optical sensor which, due to its unique properties, can work as a high-quality stair sensor, in cooperation with smartLEDs LED lighting stair controllers. The sensor works by sending narrow beams of infrared invisible light and measuring reflected values returning to the sensor.

The basic operating mode of the sensor is the distance mode, which is used to detect objects within a fixed distance from the sensor. The sensor has an adjustable range of 30-200 cm, so it can be used both for typical stairs 100 cm wide, as well as for wide stairs and passages up to 230 cm. Thanks to the ability to set the range and narrow detection angle, the sensor does not react to people passing nearby the stairs, which is a great advantage compared to popular PIR sensors. Due to the one-piece structure (the receiver and transmitter are located in one housing), the sensor can be used for open stairs (openwork or built-up on one side only).

When switched to motion mode, the sensor works well in the case of closed stairs, with bright wall reflecting light at the opposite side. In motion mode, DELTA sensor detects a change in the signal reflected from the objects moving within set distance from the sensor. The sensor utilizes microprocessor signal processing algorithms ensuring increased immunity to interference, light fluctuations and changes in operating conditions.

Range adjustment, change of operating mode

Changing the sensor mode and range adjustment is carried out in a convenient way with the help of a small potentiometer located under the removable cover on the front of the sensor.

  • Range setting indication: red LED
  • Object detection indication: green LED
  • Range adjustment – multiturn potentiometer
  • Change of operating mode: multiturn potentiometer and red LED

Follow the user manual (see tab DOCUMENTATION).

Easy electrical mounting of the sensor

The outputs are located on the terminal block at the back of the sensor:

  • +12V – power supply voltage (+8VDC – 24VDC)
  • GND – power supply ground (0V)
  • OUT – OC type digital output (NPN)

Mounting methods for sensors

The small dimensions of the sensor (diameter without cover 35mm, depth 25mm) allow discrete flush mounting.

  • Discreet installation in stair railing poles in the 35mm diameter hole e.g. in a stair baluster
  • Discreet flush mounting in smartLEDs mounting box
  • Flush mounting in standard 60mm electrical boxes using the smartLEDs flush installation box adapter.

It is recommended to install sensors at a height of 80-100cm

smartLEDs mounting box

It is a flush mounting box.

It is recommended to fix the mounting box in the wall and then to put the sensor into it. Because the dimensions of the flush mounting box match those of the sensor, the sensor fits into it quite tightly and does not require additional fixing. The sensor cover covers the flush box at the front.

smartLEDs 60mm flush installation box adapter

The 60mm flush installation box adapter enables the aesthetic installation of a stair sensor in a Φ60mm standard installation box.

The adapter consists of two elements: the adapter socket (black element) and the adapter cover (color to choose). The adapter cover is made of ABS plastic, which can be painted.

To mount the sensor:
(1) Remove the sensor cover and insert the sensor (without sensor cover) into the adapter socket,
(2) Screw the adapter socket into the 60mm flush installation box
(3) Latch the adapter cover on the adapter socket. (To remove the adapter cover, lift it slightly at the top.)
