But it stopped beeping, and did not flash or give any other noticeable indication that its batteries were low. There was no way to determine which smoke detector it was. (Or at least, none that I could figure out at 2:00 am.)&lt;p&gt;Any possible action was useless (I had no batteries handy), so I went to bed.&lt;p&gt;Thirty minutes later, same thing again. Awakened, couldn&amp;#x27;t tell by which smoke detector. I could think of nothing to do other than to remove all the batteries in all of my smoke detectors.&lt;p&gt;Bad UI.</text><parent_chain><item><author>brudgers</author><text>Ambulances don&amp;#x27;t play cello sonatas.

If the current design of smoke alarms causes people to disable them - irrespective of whether or not they &lt;i&gt;should&lt;/i&gt; - then the design can be improved.</text><parent_chain><item><author>brudgers</author><text>Ambulances don&amp;#x27;t play cello sonatas.
