How a smoke detector works

[Richard O'Neill]

  Chill out, Chip, it's just another example of the media's ever present 
nanny state mentality, reminding us that we can't hope to survive 
without their daily mandatory advice.

  In my youth firemen visited local schools each October to teach 
children the dangers of fire. We also had evacuation drills. Do schools 
still do that?

  As for smoke and CO detectors, I check my detector batteries at the 
start of each heating season to avoid being wakened in the middle of a 
long cold night by a 'low battery' alarm beep. With detector redundancy 
throughout the house I could safely wait for a telltale beep but who 
wants to be disturbed in the middle of an erotic dream? As usual, YMMV :-)
