Why does the wireless doorbell ring without someone pushing the button?
April 24, 2014 3:40 PM Subscribe
My office uses a RCWL210A
portable wireless chime as a door bell. The push-button part of the system is glued onto the wall next to the security keypad by the door. Sometimes, just entering the keycode to open the door will set off the chime, even though they are not connected at all and nobody pushed the actual doorbell button. Sometimes just raising your hand towards it to key in the code will set it off. What is going on, and how can I stop it doing that?

- The door bell is a completely separate system - it has nothing at all to do with the security keypad, we just glued the push-button part next to it because it makes sense there.
- There are no other similar chimes in our building, and the button/chime pairing code is changed to a non-default. It never goes off by itself, only if someone is using the keypad.
- It has only happened once to me, but it happens often (though not every time) to one of my colleagues. Sometimes he just has to move his hand up to the keypad, and it will set the chime off despite him not touching anything.
- Pushing on the keypad unit, banging on the wall, pushing on the plastic housing of the push-button part - none of those actions sets the chime off, so it's not that it gets jostled somehow.
- I can't reproduce it, despite quite a few tries, which is why I'm at a loss.
Thoughts we have had: static electricity buildup, some sort of interference from a watch or ring, moisture on your hands... But in general we have no idea, and my online searches have been fruitless, so I thought I'd see if anyone had a theory.
Yes, I know this is a trivial issue. But if the chime goes off when someone with the keycode is coming in, I still have to get up and walk out of my office to the foyer in an attempt to answer the door. It interrupts me for nothing, and makes my colleagues feel bad that they made me get up.
