Title: Do RR501s fail after years of use?
Post by: Dan Lawrence on December 22, 2010, 10:52:53 AM
I have 2 RR501s, one in the Living Room that is on housecode A and one in the Breakfast Room on housecode F.  Yesterday the RR501 in the BR stopped  receiving signals from the Stick-a-Switch in the Room, which now suddenly sends signals to the RR501 in the Living Room and turns off/on lights in there - from the Breakfast Room.  I presume the RR501 has failed.

Check the battery in the Breakfast Room Stick-A-Switch.
A weak battery could have made it default to A which is the code in the Living Room.

Replaced the battery, It seems the RR501 has failed. Since AHP has the timers, and can reach to the Breakfast Room/Kitchen and control the modules, I'll order a couple of RR501s from Automated Outlet after New Years.  I tried the RR501 in 4 other outlets, its dead.   Oh,well, life ain't perfect.

Try switching the House addresses and locations of the living room and Breakfast Room RR501's.

The contacts on the code wheel may be dirty.
Try rotating the Housecode wheel a few times, and see if that makes any difference.
You might also want to try using a PalmPad, and seeing if it will respond to an RF commands (try different housecodes, just for good measure).
Is it "dead" in both the "Unit 1" and "Unit 9" positions, on all housecodes?

I took out one a year ago with a static zap to the antenna.  The internal relay still responds to powerline commands, but the RF is dead.

What, YOU couldn't figure out how to fix it? ;-)

I figure the RF input transistor was fried.  It is in the queue of things to do if I ever have some spare time.  Of course, there are much higher priority items in that queue, such as replacing the bake ignitor in our GE stove.  Repaired myself for $31 and half an hour, compared with an estimated $200 service charge.  That buys a lot of RR501s.

I repaired a power supply in one myself.

Seems the zener diode they used is close to its full rating and got warm. The PCB actually started to show blackening and the solder looked flaky.
I used two of half the original voltage in series to replace it and for good measure did the two electrolytic caps also. Using a slightly larger voltage and capacity.

Tried that, when it did it the Living Room lights would not respond to the SS13, but the kitchen lights responded as they did before.  So I've ordered 2 from Automated Outlet.  One goes in the Breakfast Room (the original RR501 is back in the Breakfast room), the Living Room RR501 is back.

Now, how do you reset a SS13 "Stick-a-Switch?  The new RR501 is in the Breakfast Room but the SS13 is still stuck and sending RF signals to the Living Room RR501.  Remove the battery from it?  For how long?

Not sure if removing battery will force the Slim Line Switch to A1 like a motion detector. I just changed button cell in one of mine and it retained the programming.   :)%

I took a spare and set it to B1 from the default of A1 for the top button.
Removed the battery like I was changing it and then installed the battery back it still was on B1.
Test 2. removed battery and held a button for maybe ten seconds. Then reinstalled the battery. It was back on A1.
I don't know how long the electronics's would need to discharge alone but the button pushing made it happen faster.

You could also just use the button push sequence to set the House and Unit Codes to what you want. From where it is now.

One has to ask, why the heck didn't X10 put the same "battery change-code retention" cap in the xxxxEye motions sensors?

I found the schematic on the FCC web site.
I don't see a external cap to hold the voltage up.
Though I don't have much data on the EM78P153 IC it uses. It may have some short term memory not sure.

I've gotten disgusted.   I took the battery out of the Breakfast Room SS13 and let it set for 32 hours.  Tonight I put the battery back - and the (censored thing STILL won't see the RR501 All X10 units in Breakfast Room and Kitchen are on Housecode F (Food) and AHP can control all 3 units.

Do I toss it in the trash and get a new one?

Try setting one of the RR501s to House Code:A and see if the SS13A reverted to House Code A.
If it did reprogram the buttons to the needed House Code.
If it can't be set to the House Code you want maybe it did fail.
Side note here. I have read that the only X10 module using sticky foam tape that sticks well and damages paint when removed is the SS13A.

How do I reset buttons on the SS13?  I never set them when I first created the F housecode.  The three buttons on the SS13 were F1, F2 and F3 until this merry-go-round started but I never set them.  Now that the SS13 has "reverted" to housecode A, I have TWO SS13's controlling A1,A2 and A3 which are Living Room lights.

I am surprised the SS13A with the F House Code was not reset from A. As that is the default.
The House Code is set with the Top On button. The First Unit Code with the Top Off button.
The button sequence is in the setup sheet shipped with the SS13A.
ftp://ftp.x10.com/pub/manuals/ss13a_is.pdf

Hold the Top Button On section. The LED will flash a few times then go out. Keep holding it .If it is on A it will then flash one time.
Push the Top On button six times for F. Holding the button on the sixth push until it flashes back the present setting. It should flash six time if the F setting took.

Brian, THANK YOU!!!!!!!!!.   Finally got the SS13 to F.  Thanks for the .pdf link, it's now in my X10 folder.

Just out of curiosity, why did the SS13 default to A when the old RR501 died?

Are you sure the RR501 is dead? If you look at the beginning of this thread it sounds like the battery in the bedroom SS13 simply discharged to the point the switch defaulted to the A house code, and remained on A1 after the new battery was installed.

It was dead.  The RR501 address is F1 and when the problems began, Neither the SS13 or AHP could see it. In AHP it was there, but would not respond.  I ordered 2 new RR501s and that's when the SS13 problems began.

Everything works the way they are supposed to now.  Each RR501 gets only the RF signals they are set for and each local control (SS13) works the way they supposed to.   

My view of X10 is it's to make life easier, not I'm there to serve it.

Sounds like two separate occurrences.
The RR501s did fail and the battery got so low it went to default House Code A Unit codes 1-3.

That's exactly what happened.  First the RR501 died (at least the RF part) so the SS13 could not find it and defaulted back to Housecode A.  Ordered 2 new RR501s, when they arrived,  set one to House Code F, but then had to use what you linked to get the .pdf instructions, reset the SS13 to House Code F and everything works the way they always did.
