I purchased the alarm system with a second keypad, so I'm wanting to know if it can be mounted in the master bathroom. I'm not sure if the moisture from the spa tub and shower would affect the keypad or not.
I wouldn't think it would have a problem with it unless it was in the bathroom. It would not work in a high humidity area for long. But I don't think your bedding is damp, so affecting the keypad should not happen.
