Yes, you can use more than one Transceiver in your home when the range of your remotes is not sufficient. The Transceiver is using so called collision detection to prevent signals to be disturbed when more than one Transceiver is transmitting. Transceivers will wait for a quite power line before transmitting their data. To prevent your Marmitek X-10 System to become slow or to prevent dimming from becoming less smooth, make sure that the units are placed as far away from each other as possible.

Yes you can. Turn ON the LM15 by the mains switch will put it back to the state before it was powered OFF.

If the unit was in the OFF state before it was powered off, it can be turn ON by flipping the mains switch on/off 3 times. Each ON time must not be more than 30 seconds, otherwise the 3 time counter will be reseted.
If the unit was in the ON state before it was powered off, it will be put into the ON state everytime it was powered ON. Only the remote controller can put it to the OFF state.

Yes, The LM15 responds to the ALL LIGHTS ON command, and to the ALL UNITS OFF command. However, the LM15 cannot dip the lights.

LED lighting can be controlled by all X-10 receivers, except the AM12 (this is equipped with an autosense function. LEDs continue to be slightly illuminated because of the autosense current.) and the LW12.

LEDs cannot be controlled by the dimmer modules if their total power falls under the minimum load of the relevant module.

Low voltage LEDs (which are controlled via a transformer) and 230V LEDs which often have internal capacitive conversion to low voltage must also be taken into account. These influence the strength of the X-10 signal and can, therefore, cause interruption to the lighting network. In practice, the LED lighting can usually be switched on but cannot be switched off. This can be solved by using an additional FM10 or FD10 module.

The module will retain the same position until it gets a command to change position. If the module was in the ON position, it will return to the ON position after a power failure.
