You are welcome.
The fact that the Date Code 2005 works for you. Gives me more information on how different versions are working.
When yours gets here. I will have another clue.

I really want to get at least one more from x10 but not knowing for the fact that it will work like your or not.

The new ones may not work like the 2005 one I exchanged with you.

I have a X10 PH508 Date Code 10L52 and an X10Pro PSH01 Date Code 10F25. Both bought in the last month from independent X10 dealers on EBay. At a very reasonable cost.
Both of them didn't make any noise when the console was armed away or home.
They did not work exactly the same when an alarm was set off.
They would take about ten seconds to sound.
Then sound for four High/Low tone cycles.
Stop for about ten seconds.
Then sound again for four High/Low Tone cycles.
Alternated between four sound cycles and ten second pause as long as the alarm was sounding.
Now if X10 has done things in the 2011 Date Codes. I can not say what a brand new one would do.

Most folks may find the intermittent sound cycles OK but definitely not ideal.
Guess it is better than sounding with an arm on the console.  ;)

Received the Date Code 09A03 PH508 today.
I can verify it does sound two Hi/Low Tone cycles with a SC1200 console "Arm Home" Function and Arm with the KR32 KeyFob Function.

I have not formed an opinion on it when used with a SC1200A.
More tests will be done.

All it takes is one On/Off cycle or All Lights On/All Units Off to trigger it. Older ones need four or more one second cycles to trigger them. The newer 2010 ones also needed more cycles.

How is the volume level? As loud as the old ones?

Well I don't have a sound level meter, but my ancient ears say all the new design one are not as loud.
I know the 2009 and 2010 ones I have are not as loud.
Maybe vlong can give us his thoughts on the 2005 I swapped to him for the 2009.

I am not surprised the 2005 I sent was louder. The older ones have a real audio output stage with a transformer driving the sounders. The new ones look like a pair of push pull transistors driving the sounder directly. I saw no audio output transformer in any of my 2009 or 2010 units.

I played with the 2009 today and compared it to both of the 2010 ones.
Both 2010 units have a firmware sticker of. P11021C PCB:042010=12014B
2009 unit firmware sticker P11021B PCB:042010=12014A
Can't read the values on the surface mounted resistors and caps so I don't know if there are different components between them.

Yeah, general purpose transisters are cheaper than transformers. I think those piezo alarms are high impedance, I wonder if the transformer acted as a step up xformer.

I made an error.  :'
I was thinking of the SH10A that has the output transformer.
I just looked at an old PH508 and it didn't have any transformers for sound output.
It does have a plus and minus 30 volt power supply with reference to common.
