<div><br></div><div>This will be my choice. I hope because its hard to find one for the deaf that dosen't cost me my arm and both my legs. I still have to email them about the silence thing. I have to make sure I can shut it off altogether. No sense in scaring the wee jees out of the neighbors....you know what I mean? I don't know if I need the smoke part but I can always shut it off if I'm cooking something. I believe this can be run on batteries but it only says back up so I have to be asking them that too. Unless somebody here knows?</div><a href="http://www.hearworldusa.com/product...Alarm-with-Battery-Backup-&-SL177-Strobe.html" target="_blank">http://www.hearworldusa.com/product...Alarm-with-Battery-Backup-&-SL177-Strobe.html</a>
