I connected my Piezo Buzzer to my Alarm Panel Add-on board as shown on the "Wiring a Piezo Buzzer for Door Chime" installation instructions.  At first, I believe I was hearing a sound when I opened my door.  To test the range of the sound, I started walking around the house and pressing the beep button on the SmartApps panel to trigger the sound.  It was working like that for a while but then there was no sound when I opened any door.  At first I had it wired to the OUT and GND pins on the board.  Then I moved it to the OUT and GND on the terminal block and then onto terminal 4 and GND.  Nothing was helping.  Now, I can't even get the beep sound when I put it back on the OUT and GND pins on the board.

I'm still getting signals when I open or close any of the circuits but the buzzer is not working at all.  I did enable the Low Level Trigger via the SmartApps and verified the buzzer is still functioning.

Not sure what else I can share in this message but any help would be much appreciated.

  • I have the buzzer working successfully.  Attaching screenshots from my SmartThings app to help anyone that has been unsuccessful.


    I have 2 boards, and the buzzer is connected to my add-on board using the female-female cable connected to the instructed pins.


    1. You will need to configure the buzzer using the "Alarm/out" on the board setup screen.  I set this as a "Momentary Switch"

    2. Add a new routine

    3. configure the routine to "turn on" the piezo when "something opens". I set this to beep on my less frequently used doors/windows so that it is not constantly beeping with the heavy traffic entry points.

    4. On the "Things" listing screen, find your piezo and click the name (don't turn it on), and you will get the screen to configure the pulse/pause.


    Hope this helps

  • I'm having the same issue. I've connected the piezo to the 6 zone alarm panel to zone 3, have it set in routine to beep 3 times when front door is triggered and still get nothing. 


    I'm starting to think that the add - on board would have been the better option. Or have that as the standard board. In his video 5:45 sec he clearly has it demonstrated but never really shows how he programmed it to work.

    anyone else have the same issue on the regular alarm board? 


  • Followed Benjamins example however the only option I get is to set the delay.


  • I have tried all of the above. I have successfully added the new routine, but when I try to add the buzzer as a thing nothing shows up during search. As I went ahead and purchased an add on board solely for getting this to work I have two buzzers now and have tried connecting them to multiple spots, but they simply will not discover. Any ideas?

  • I have had it working for over a year.  Every time a zone opened with would toggle the buzzer.  One day it just stopped working.  I have tried everything and I can not get it to work again.  I might try resetting the boards and starting from scratch.  I wish someone would post a step by step of getting it working.

  • There is really not a clear cut answer to this post. Here is my problem: Looking for some help with buzzers. I have a 2 story house with panels upstairs and down. When I hook up buzzers behind both panels the buzzer sound seems to fade to the point of not achieving desired effect. Does the multiple buzzers drop voltage too much for sound or do I need some louder buzzers? Right now I have 2 small buzzers similar to V2 kit buzzer wired in parallel using the Add-On board output pins alongside 5V output. Would splitting a buzzer to another output help? I have the last output terminal on the Add-On board and Zone 1 on the Main Board open for use. Any suggestions would be appreciated.
