Safety and security features in a Real Smart Home don’t only mean protecting the occupants and the building itself, but it also means that the installation itself needs to be safe and secure. Loxone devices are designed and built to last. We are of the view that a Loxone system should last as long as a typical electrical installation – not needing to be replaced every couple of years as would likely be the case with off-the-shelf devices.

No Gimmicks, Real Smart Homes –
Loxone the 360° solution

The installation of a Real Smart Home for your customers is not only about features but also needs to offer peace of mind that the devices used are of a high quality and built to last. By installing Loxone components, you’re not only delivering a feature-rich, future-proof Real Smart Home for your customers – but you’re also delivering a system that is safe and reliable.

In this blog, we’ll take a look at some of the behind-the-scenes devices and components that you should be using and information you should be considering so that both you and your customer benefit from a reliable installation.

Einbruchschutz

A safer installation with Loxone products

All Loxone products are designed to last. The devices in Real Smart Home are not like many other general consumer goods you can buy off the shelf that will likely need replacing after a few years as they become outdated or even obsolete. Loxone components are intended to last as long as the electrical installation of a home, if not longer. To ensure this level of reliability, our products include a number of safety features.

Safety features of the Loxone product range:

Verpolungsschutz
Reverse polarity protection

The majority of hardwired Loxone products work off 24VDC SELV.

In order for you, as a Loxone Partner, to be able to guarantee a reliable and error-free installation, we’ve put a lot of thought into reducing room for error in the installation itself.

Each hardwired Loxone peripheral device is equipped with reverse polarity protection so that if you accidentally swap the 24V and Ground pole, you don’t risk damaging the actual device.

Netzteil
Short-circuit protection

Another way in which using Loxone components offers a reliable and safe installation is that our power supplies have short-circuit protection. This means that if you were to accidentally switch the plus and minus connection, neither the Loxone device or the power supply itself will be damaged – this is because the power supply itself automatically shuts off in the event of a fault.

Temperaturmanagement
Temperature management

As we develop all Loxone lighting products in-house, we’re able to give more attention to individual elements such as a built-in temperature management system. This feature plays a very important role on several fronts. Firstly, it aids a long lifespan of the LEDs – which is a very important part when it comes to our Partners delivering a reliable installation for their customers.

If the temperature of an LED bulb is too high, this not only hinders the life of the LED, but also affects the colour of the light it produces. That’s not a worry though, as this will not happen with Loxone lighting products.


You need to ensure that your installation meets regulations. As Loxone spots are not fire-rated, you should determine if a fire hood is needed. Chat to our support team or your Partner Consultant if you need more information on this.

Weitspannungsbereich
Built-in voltage regulators

The Loxone lighting products can all be operated in so-called wide voltage range. This means that variances in the supply voltage of between -10%  and 5% will not affect the quality of light or the lifespan of the LED itself.

A safer installation with Loxone products

All Loxone products are designed to last. The devices in Real Smart Home are not like many other general consumer goods you can buy off the shelf that will likely need replacing after a few years as they become outdated or even obsolete. Loxone components are intended to last as long as the electrical installation of a home, if not longer. To ensure this level of reliability, our products include a number of safety features:

Betriebsspannung
Operating voltage protection

The operating voltage of components in a Loxone Smart Home is 24VDC which comes under the category of Separated or Safety Extra Low Voltage (SELV). Even though SELV is considered to carry a low risk of dangerous electrical shock it is still addressed in the regulations and therefore care should be taken to ensure a compliant installation. The use of fuse terminal blocks is a good way of reducing the risk of overloading cables from a fault in the installation. They so provide a perfect landing board for terminations in the panel.

We recommend using terminal blocks for all cables being brought back to the cabinet in a Loxone installation.


We recommend that you have separate 24V power supplies – each on its own protected circuit – for the controls (Miniserver and Extensions), the peripherals (Touch, Motion Sensors, etc), and the Loxone LED lighting.

Blitzschutz
Lightning protection

Even if you’ve installed the best equipment and followed all the standards and regulations, your customer’s home is still at risk if Mother Nature decides to strike. Offering a reliable installation means also taking this into account and including components (such as surge or overvoltage protectors) that mitigate the potential damage a lightning strike could cause by dissipating the surge.

Although you can’t completely protect a house from lightning, the above is still good practice to follow. This is one of the reasons that a true Loxone installation only uses SELV power supplies.

In many installations, however, the GND of the Loxone 24VDC SEcannotly can not be prevented from being connected to PE by external devices.

Normally devices such as patch panels, PCs, routers, access points or similar IT equipment causes this. In order to prevent a potential current flow (compensation current or, in the event of a fault, a fault current) through the Miniserver, PELV cabling should be used.

We recommend that the planning and installation of a Loxone Smart Home are carried out by a trained Loxone Partner. Qualified electricians may be required for parts of a Loxone Smart Home installation.
Brandschutzschalter
Fire protection switch

In compliance with wiring regulations, all circuits must be protected by an RCD and appropriately rated MCB. However, this protective measure on it’s own won’t be able to identify fault arcs.

Fault arcs can be caused by unsafe or exposed contacts or damaged wiring or cable insulation. We therefore recommend that the electrical installation in a Loxone Smart Home also has external electrical fault detection equipment (e.g. arc fault detectors). As Loxone, we don’t sell Arc Fault Detection Devices (AFDD) but using such a component in a Loxone Smart Home is best practice.

When it comes to fire alarm systems, you can already connect a fire alarm switch to the digital input of a Miniserver or Extension to trigger alerts through a Loxone Smart Home in the event of a fire.

We’ve taken it a step further. Using AFDDs for fire protection has long been standard, if not mandatory in industrial installations. Even though a Loxone system is designed for domestic installations, our system can now specifically take a signal from an AFDD and trigger a fault arc notification. You’ll find a dedicated Input (If) in the Fire and Water Alarm Function Block in Loxone Config.

Tree Sensorik
Tree sensors

The way our Tree Technology has been designed allows for Loxone Partners to easily connect sensory peripheral devices in a Loxone Smart Home. All communication between security-sensitive Tree products is fully encrypted – offering peace of mind for both you and your customers.


Connect any Tree components that are installed outside the home (such as the garden, driveway or patio) to a separate branch on the Tree Extension. This aids in the reliability of operation due to separation from external variables.

CAT 7 Kabel
CAT 7 Cable

We recommend that all Loxone Smart Homes installations are done with CAT7 for maximum functionality and in the interest of future-proofing.

The CAT7 cable is ideal for Loxone Tree devices. With four pairs, each of which is double-shielded, better protection from sources of interference is afforded, and with the thicker cores of a CAT7 less volt-drop will be experienced. It is typical that the requirements of a customer and the way they use the different rooms in their home will change over time. This, as it gives greater flexibility for programmable changes in the future, is another reason why you should be using CAT7.
