Digital potential-free sensor module

The digital potential-free sensor module allows you to connect maximum three sensors equipped with an NO contact or an NPN transistor output to the Niko Home Control installation. The connected sensors should be suitable for applications with safety extra-low voltage (SELV). Typical applications include twilight switches, smoke detectors, motion detectors, door communication systems or contacts used in locks, telephone interfaces and alarm installations.

Digital potential-free sensor module for Niko Home Control

Reference code
550-00210

This module is used to connect sensors with an NPN or digital contact output and safety extra-low voltage to the Niko Home Control installation, for example, twilight switches, smoke detectors, motion detectors, door intercoms and videophones, etc.

Specification description

Digital potential-free sensor module for Niko Home Control. The digital potential-free sensor module allows you to connect up to three sensors to the Niko Home Control installation. The sensors must be suitable for use in applications with safety extra-low voltage (SELV). Examples are: twilight switches, smoke detectors, motion detectors, door communication systems or door lock contacts, telephone interfaces, alarm installations, etc.

When a connected sensor is activated, the module sends the address to the controller, which then activates one or several pre-programmed actions. The contact can be temporarily closed manually by pressing the button to simulate a particular status. The real input will in that case be deactivated for two minutes.

The distance between the sensors and the module should not exceed 50 m. A maximum of three sensors can be connected per module.

When the module is functioning properly, the STATUS LED will light up in TEST mode only. If one or several errors occur, the LED will blink to indicate the error code of the error with the highest priority.

Suitable for SELV sensors with an N.O. contact or an NPN transistor output

Connected controller for Niko Home Control II

The connected controller is the central module of every Niko Home Control installation for bus wiring. This module contains firmware that can only be programmed with the Niko Home Control programming software 2.1.1 or higher. It covers all basic functions on which a Niko Home Control installation is built. The basic functions include: • The intelligence directing the logic to the installation. Through the configuration software, the logic is saved locally on the controller. • The power supply module providing an input voltage of 26 V to the bus, the cabinet modules and the controls. Depending on the size of the installation, separate power supply modules can be added. • The connection to Niko Home Control IP devices such as touchscreens and external video units. A built-in router allows the user to connect up to 3 devices directly to the controller. With an extra switch, this number can be increased. • The connection to the internet. This enables the user to control the installation both indoors and outdoors (via mobile networks such as 3G, 4G, GPRS or WiFi hotspot) using mobile devices (smartphones and tablets with iOS or Android). The module has a TEST button to verify the proper functioning and status of all other modules. The SERVICE button allows you to perform waiting Niko upgrades. Each installation must consist of one connected controller. After registration on https://mynikohomecontrol.niko.eu, your installation is connected, enabling control through the app via your smartphone and tablet, and you can enjoy the Niko services for upgrade or diagnosis of the installation.

Touchswitch, connected customisable control screen for Niko Home Control, 24 V

Touchswitch is a completely customisable control screen for Niko Home Control with an extremely user-friendly interface featuring clear symbols. The screen is automatically activated when your hand comes near. That way, you can switch or dim your lights, set moods, set ventilation modes, adjust blinds and sun blinds to the desired position, in one operation. In short, all possible Niko Home Control control types are available. Do you have a Niko Home Control thermostat (ref. 550-13050)? Then you can easily set the temperature with the touchswitch. With the Niko Home app not only can you choose which controls are displayed or where they are displayed on the screen, but also the way you navigate through your control screens. You can download this app for free in the app store or play store. The screen can be easily mounted in any standard flush-mounting box and is powered by a separate 24V DC supply (e.g. 340-00050) The screen communicates via your wireless home network with the rest of your Niko Home Control system. You need an active internet connection to activate the screen. This internet connection ensures that your screen and Niko Home Control installation are always up-to-date, and have the most recent functionalities.

Power supply

The power supply, in combination with the connected controller, provides an extra input voltage of 26 V to the bus, modules and controls. An extra power supply is only necessary in installations for which the power of the built-in power supply of the connected controller is insufficient. Up to 2 extra power supplies can be connected to installations with a connected controller. The MASTER button is not used, as the built-in power supply of the connected controller is always the master. For more information on the required number of power supplies, you can consult the installation manual.
