Hello, I got broadband recently. I also have Eircom Phonewatch. From previous threads I was under the impression that I had to get an additional splitter installed to prevent the broadband interfering with the Phonewatch monitoring service. So, I ordered a sevice call from a Phonewatch technician to install which they are schedule to do this week. Anyhow, I left my house yesterday and turned on the alarm as a matter of habit. 10 minutes later I got a call from Phonewatch saying that the alarm had gone off. (It was a false alarm, I had left conservatory windows open). Now my computer and broadband were turned off at the time. How did Phonewatch receive the signal? I haven't had their splitter installed yet. Is there no interference issue when broadband is turned off? The Phonewatch lady told me that sometimes the system works with broadband and sometimes it doesn't but it would be better for me to get the splitter installed as its more consistant? This sound very strange to me. So, my question : if I'm happy to turn off my PC and broadband when I leave my home, do I really need this additional splitter at a cost of ~€90?? Thanks.
