Thread: x10 repeaters/amplifiers

    Default x10 repeaters/amplifiers

    Hello All,

    I've installed some powerflash's on some PIRs in an outbuilding which is 100m from the house via 2 fuseboxes. I can pick up the signal from the powerflash in the house on some sockets and not others. I'm guessing it's the distant and most probably a bit of noise from the house which to date hasn't effected anything because the signals have always been strong enough..

    So, was looking at repeaters/amplifiers and wondered if anyone had any experience with them and what makes/models are good or bad?

    Would a marmitek coupler/filter be the first step or should i go for something like the XTB-IIR??

    Thanks

    You should always use an X10 filter such as an FD10 in the consumer unit. This stops noise and possible X10 signals from entering the house, and your X10 signals from leaving the house.
    As for the others I can't comment. But a repeater would possibly be a good idea. Most X10 signals have a maximum wire distance of about 40m to 50m before they degrade sufficiently to start causing real problems. Saying that some of the newer modules are much better than the older ones, and can transmit over greater distances.
    Do you have any other X10 modules in you house. Just thinking about address collisions etc. Also What house code do you have set. House codes such as M and N seem to be more prone to noise than others.

    thanks Toscal.. I unplugged all my other X10 modules in the house and still get the same, so from what you say, distance is most probably the problem as I've moved the powerflash to the house and all works ok. I'm surprised it works atall really as the cable length must be well over 120m(but it is a whopper of a cable!). The commands from my CM15 reach the outbuilding fine and never miss(they are X102 modules from HK), so I'm going to look at the XTB-IIR, but as you suggest, I'll fit an FD10 first.

    On the plus side my PIRs and relays work a treat!

    thanks again.

    IF you are using a CM15 then why not get is to send commands over RF via a macro then just buy a TM13 to plug in to a socket in the out building. Mind you I think once again you may run into distance problems. As the RF works to about 50m or so before you can run into reliability issues.
    Though if you are handy with a soldering iron you can mod the cm15 to improve its RF range.
    Where is the Cm15 plugged into. The closer this is to where the cable goes from the house to the out buildings the better.
    Let me know how you get on.

    Good idea Toscal.. Problem is my house is made of 14 inch flint walls which seem to block most signals which is a pain!

    After a weekend of trawling the web and emailing Jeff(the chap who makes the XTB) I've come to the conclusion that i need an FD10, a few filters and an XTB-IIR. With any luck i'll have it up and running(or not) in a couple of weeks and will let you know the outcome.

    fingers crossed!!!!

    Update as promised:

    I recieved the XTB-IIR this morning and it took me a few minutes to install. Without adding any filters what so ever everything now works perfectly without fail. What a great piece of kit - I highly recommend it
