Query: Works too well!

As soon as I attached the alarm to the bracket, it activated...and began to go off. The Hush button did not stop it. Taking it down and sealing it in a box did not stop it. And there is no way to take out the battery. This is the zombie alarm, IT CANNOT DIE. (Okay, judicious use of a hammer did shut it off) Seriously, on a unit where you can't remove the battery the Hush button *HAS* to work. On the one I got it did not.
