1.When more than one phase is used for your electrical system, it is necessary to couple these phases for the Marmitek X-10 signals. For coupling you can use FD10 Phase Couplers/Filters. You only need to install a Phase Coupler/Filter when your wall outlets and light switches are divided over more than one phase (more than one group is no problem). For bigger buildings or longer distances we advice you to use an active repeater instead of passive FD10’s.

2.It is possible that Marmitek X-10 signals are attenuated by devices and lights which are connected to the power line. In a normal home situation this effect is negligible (the Marmitek X-10 system is using active gain control to eliminate the effects). However, it is pos- sible that a particular device in your house is attenuating the signals so much that the range of Marmitek X-10 signals is decreased significantly. When you have range problems, it is wise to try to locate the device which is attenuating the signals simply by unplugging devices from the power line, and testing the differences in range for your Marmitek system. When e.g. your conclusion is that e.g. your computer monitor is attenuating the signal, you can use a FM10 Plug-in Filter between the power line and the monitor to eliminate the effects.

Known devices which can cause attenuation are:

PC Monitors

PC’s with heavy internal power supplies

Old Televisions

Copiers

Fluorescent Lights

Gas Discharge Lamps (Energy Saving Lamps)

3.Some (old) devices are able to disturb the signal by transmitting noise on the power line. Because the Marmitek X-10 signals are transmitted on 120 kHz, only noise on or near this fre- quency will have influence on the range. When you use a FM10 Filter to connect this device to the power line, the noise will be filtered.

4.The Marmitek X-10 protocol has several mechanism to avoid modules to be switched on or off by other sources than your Marmitek X-10 Controllers. However, it is possible that the Marmitek X-10 signals are disturbed by e.g. baby phones which are in TALK mode (continu- ous transmission). When these kind of signals are present on the power line it is possible that the Marmitek X-10 signals will not come through.

5.The mains do not stop at the front door of your home. Everything that is attached to mains nearby your home can have influence on Marmitek X-10 signals (e.g. heavy machinery). If you think that your system is influenced by devices out of your house, it is advisable to install FD10 Phase Coupler/Filter on each phase entering the house. These filters will block signals coming into or going out of your house, but will also match the impedance for the mains. The FD10’s will not only filter but will also couple the phases (please see 1).

FAQ

What is the reason for modules to switch on/off spontaneously?

It is possible that a Marmitek X-10 System is installed at one of your neighbours using the same House Code. To solve this problem try to change the House Code of your system, or have FD10 Phase Coupler/Filter installed at your incoming mains.

My modules will not respond to my controller.

Make sure that the House Code on all Modules and Controllers are set to the same House Code (A .. P).

LM15 specifications

The Marmitek LM15 is an advanced solution in the realm of home automation, specifically designed to improve the convenience and functionality of audio and video distribution. This innovative device serves as a versatile remote control system, allowing users to operate various electronic devices seamlessly from a single point. Its power lies in its ability to integrate multiple technologies, ensuring a streamlined user experience.

One of the standout features of the Marmitek LM15 is its compatibility with a wide range of devices. It supports infrared devices, enabling users to control everything from televisions and audio receivers to other home appliances that operate via IR signals. This extensive compatibility makes the LM15 a one-stop solution for managing multiple devices in a smart home setup.

The LM15’s learning function is particularly noteworthy. It can learn from existing remote controls, allowing users to consolidate their remote devices into a single interface. This feature not only saves space but also simplifies the user experience, eliminating the need to fumble through multiple remotes every time one wants to change a channel or adjust the volume.

In terms of design, the Marmitek LM15 is user-friendly. Its intuitive layout and clear display make it accessible for individuals of all ages. The device is compact and lightweight, ensuring that it can fit comfortably in any living space without adding clutter.

Another key characteristic of the LM15 is its advanced transmission technology. It uses RF (radio frequency) to communicate with devices rather than relying solely on line-of-sight infrared signals. This allows users to control their devices from different rooms or even behind obstacles, enhancing the versatility of home automation.

Security is also a crucial feature of the Marmitek LM15. With built-in encryption, data transmitted between the remote and the devices it controls is protected from unauthorized access. This level of security is essential in a world where smart home technology continues to evolve and integrate more deeply into everyday life.

In conclusion, the Marmitek LM15 is a powerful and flexible remote control solution that can significantly enhance home automation. With its compatibility with various devices, learning capabilities, user-friendly design, advanced transmission technology, and security features, it stands out as a reliable choice for anyone looking to streamline their home technology experience. Whether for entertainment systems or other electronic devices, the Marmitek LM15 helps create a more integrated and enjoyable living environment.
