TM751 vs PAT03. I must be missing something - weird behavior

(1/6) > >>

DCUNY:
Hello everyone,

I've gotten some great help here in the past and really appreciate it.  I'm attempting to refine my setup by replacing the TM751 (which when turning on using address A1 makes a loud click) with the PAT03 which has the switch on the front for the unit code.  My understanding is if I set the unit code to 9 then there will be no click when an A1 "on" command is sent.

For context, here is a link to my original post:

I unplugged the TM751 & plugged in the PAT03 into the same outlet where the TM751 was plugged in. 

The problem is the PAT03 is not recognizing 2 of my 3 MS16A motion sensors.  It seems like if I fuss with the antenna on the PAT03 they sometimes are recognized. 
If I unplug the PAT03 and replace it with the TM751 all 3 sensors work flawlessly.  But the loud click!!!  I'm trying to get rid of the click by using the PAT03.

What am I missing here?  Is it possible I got a defective PAT03 module?  It looked like it was new out of the box but who know. 
Is there something about the PAT03 that would cause this behavior?

Should I be trying something else to eliminate the click from the transceiver? 

Thanks in advance for your help.

Setting the code dial to 9 doesn't affect the clicking in the PAT 03.
Setting the dail to code 9 means the outlet on the PAT 03 responds to the house set and unit 9 not 1

If you set the Unit code switch  to 9 on the PAT03. It will not click the outlet switch for the outlet control if the MS16A is using the default A1. If you set the Unit Code switch to 1. Then it will click the outlets switch just like the TM751 does.

If you temporarily set the PAT03 to unit code 1. Do all three MS16A sensors control the PAT03's internal switch and clunk?
It does sound like the PAT03 maybe not as sensitive to the X10 RF signals from the MS16A sensors.

Thanks for your response.  When I set the unit code to 1 on the PAT03 all three sensors don’t switch it on.  The sensors are only about 10 feet from the PAT03 and I’m astounded it isn’t working. 
I inspected the PAT03 closely and there is a piece of plastic sticking out of the case near where the antenna assmbly is located. 

Would it be better if I tried the RR501?  Maybe I have a bad PAT03...

Thanks

Sorry I miss under stood the OP.

I sounds like it's bad, it should have better RF then the TM751 from my understanding.
