Our smoke/fire detector nearest the kitchen has a twist lock mount, very easy to take off and put back on. The only problem is that we will sometimes forget to put it back on. Taking the battery out could pose a simular problem. I like the suggestion of Frank Martin, to use a shower cap ...I might add a hanging colorful ribbon strip as a
reminder of not being protected until that shower cap comes off.
Thanks Frank for telling us about the shower cap.
