I have the original system. Yesterday my smoke alarm activated there, was no detectable smoke in the house (got call promptly), my wife and I do not smoke and we were not cooking. After trying to silence the alarm to no avail I replaced the battery that quieted the alarm and reinstalled it. Today we now notice a yellow light is on which was not on before except when it alarmed yesterday. .

Going past the click to get to the bump did the trick. Did not read this in the written installation instructions. Many thanks
