This list of part numbers may help you. As Dan indicated most of the modules where OEM from X10. The Black and Decker ones where also but not on the list.
http://www.x10pro.com/pro/crossref.html1) Is a security type motion sensor. Did you get any of the Added AHP programs like On Alert as part of the kit?
http://kbase.x10.com/wiki/Motion_Sensors3) PHH02 is the X10Pro version of the X10 SC546 or the retail packaged RSC15A Chime Module.
4) TM751 is a transceiver that can receive RF commands from things like the X10 Motion Sensors [not the security ones] hand held remotes etc.
It has no power line receiver in it so the CM15A can not control it by power line. I believe AHP could be set to send an RF signal to control it.
Since the CM15A also can receive the X10 RF signals it may not be needed.
5) HR12A Palm Pad can send an RF X10 command to the CM15A as it can receive those signals. On point. AHP defaults to Auto Tranceive all house codes. You may have to go into the hardware configuration and pick the tranceived house codes.
What version of AHP do you have and did you get any of the added software add ons?
