Question:
WCLT 1430 reports a fatal house fire, where there were 3 smoke detectors but none of them had batteries.

They do not go on to explain Type II errors, namely if the damn things keep going off when there is no fire, you take the batteries out. Nothing is more common. That's why, when a house burns down, you often find no batteries in the smoke detectors.

The obvious improvement needed is a smoke detector that bursts into flame if you take the battery out, as a safety measure. Your house can't burn down if it's already burned down.

Failing that, a smoke detector with a snooze alarm.

Answer: Maybe you've not tried to sleep with seven of them, powered w/battery backup, daisy chained together, going off randomly for a few cycles at a time. The closest two 6' and 12' from the bed. And the power source not noted on the electrical panel (local inspector likes it that way). And not enough 9V batteries in the house to replace them all. If it happens again, I will remove all of mine and replace them with battery units, just so I *can* remove the batteries.

Snooze alarm is a good idea, for cooking disasters and breaking in gas fireplaces.
