Query: False alarms, and this unit CANNOT BE SILENCED!

The silence button on this unit rarely works. Most times you press the hush mode button, nothing happens. Sometimes pressing it will result in it saying "hush mode activated" . Other times it will say "Hush mode cancelled" and it will continue to beep at you. About 90% of the false alarms, pressing the button does not stop the beeping. What a horrible piece of crap. Pressing a button marked hush should IMMEDIATELY SILENCE THE ALARM. It does not for this unit. It is excruciatingly painful trying to take this unit down and yank the batteries because I burned dinner. Then when I put the batteries back in again, it runs through a 30 second test of the alarm which cannot be silenced. Most annoying fire alarm ever. Save yourself the frustration and DO NOT BUY THIS WORTHLESS PIECE OF CRAP!
