I wasn't sure if you counted the "E" as part of the word count. I chose "SNOOZE". But now I think of it, this would've been far to easy to answer. I'm a little confused about the context of the question with that said.
Are you asking for a 5 letter word that is ON A STANDARD AMERICAN ALARM, the thing that wakes you up? Or an alarm you might pull or set of during Fire or Burglary?
And asked partially prior, are you looking for another word for alarm and is it in ENGLISH?
Some of these questions may appear odd but since you have no answers, it's worth a shot to ask what you mean.
