I've been a little busy minding my X10 store on Ebay (Big John's Place) but I did have a chance to range test the KR32A AND KR10A remotes with both consoles.
I won't give you any distances because that will vary according to any individual install and the construction of the building but I will say that the new SC12A and the KR32A have a little better range than the DS7000/PS561 even without an antenna. I can hit the SC12A from the street with either the KR32A or the KR10A. The KR32A will activate the DS7000 from the same distance, the KR10A will not.
I can activate the SC12A or the DS7000 from inside my vehicle on the driveway with the KR32A but not with the KR10A.
The KR15A "big red button" will not activate the SC12A as it does the DS7000 console. Also,the SC12A will not transceive the KR15A like the DS7000 did.
I should note here that the KR15A will work ONLY with the DS7000/PS561 OR an RR501 OR TM751's from 2001 (blue box) or earlier. They simply will NOT work with newer TM751's, the CM15A or the new SC12A console.
I'll be tackling the DS12A door sensor next. I likely wont be able to use them in my system because of my door mouldings but I'll test them for comparable range. I presently use recessed mag switches in two doors instead of the surface mounted variety.
The terminals for an additional sensor are in series with the built-in reed switch so ONLY an ADDITIONAL magnet/contact set can be used unless one either glued a magnet to the builtin reed switch or soldered a jumper across it.
Would have been nice if they would have provided an either/or jumper so you could either add a switch or use an external one like I would have to do.
More later on this weekend.
