Is there a way to replace UM506 with something with quieter relay?

[Tuicemen]

I had forgotten about the PAT03 https://www.x10.com/pat03.html this has the quiet relay.
I actually tested this module and it performed very well seeing remote signals even from the weak credit card remotes which my old tm751 would not.

Thank you everyone for your ideas.  I'm truly a newbie at this .

Given the urgent level of family dissatisfaction with the noise of the UM506, I decided to start by ordering the Insteon 2450 I/O Linc module.  It will be here tomorrow at the latest.  I downloaded the detail manual and am confident I can program the X10 capabilities in the module.

Once I have the 2450 up and running I'll probably replace the TM751 transceiver with the quieter PAT03 (thanks Tuicemen).

I will advise when I have the 2450 working.

Thanks again,
Denis

However the TM751 should only click on a unit #1 signal of the house code it is set to you shouldn't be using this unit number for this operation.

@Tuicemen, I'm not knowledgeable enough yet to understand your comment above.  Does this mean if I reconfigure the MS16A sensor to a unit number other than 1 then the TM751 won't click?

If I change the configuration on the MS16A does that change survive a battery change when the AAA batteries go dead?

thanks,
Denis

Yes the TM751-PAT02 is hard coded to Unit Code 1 and the House Code set on the front dial. If the MS16A is not using Unit Code 1. It will not click On and Off. The output on the bottom would not go On and Off. So if  you are using the output on the bottom. It has to click for the output to work.

If it is a RR501-PAT01-PAT03 it could be set to 1 or 9 for the Unit Code with a slide switch and House Code on the front dial.

The Motion Sensor may revert to A1 if the battery goes dead.

Also X10 Motion Sensors also have a Dusk-Dawn sensor. It will send an On when its Dusk and an Off when its Dawn. To the next highest Unit Code above the motion unit code. So your MS16A is sending an On and Off to Unit A2 if the sensor is on the default A1. Unless you disable it with some of the button pushes and LED flashing sequences.

Thank you Brian for the detailed explanation on how the sensor works. 

The IO/link module should be here tomorrow. 

Right now the TM751 is in the garage and not bothering anyone.

Thx,

Update for everyone who has helped me with this.  I installed the 2450 I/O Linc unit.  The click is almost silent.  Very good!   

I’m going to see how this goes.  I’m not sure if I’ll try the PAT03 to see if I can get the transceiver unit out of the garage.

Thanks to everyone who helped me out with this.

Thanks for the update and the 2450 I/O Linc worked well for you.
