re mixing -- I would only guess that you CAN'T use these things with a Niles system. The Niles sensor outputs are not a "bus" signal. They need to be processed through the input of a Niles box...in other words, you can't put them in parallel. Also, Niles says you can't use more than one sensor in a room, also making them different from other brands I have run into.
A good answer is easier with a clear question giving the make and model of everything. "The biggest problem in communication is the illusion that it has taken place." -- G. “Bernie” Shaw
