    Let's get it right here...the fault probably lies on UL Labs shoulders,
    for probably quickly approving the smoke detector for roach motel
    builder lick it and stick it applictions.

    AC powered smoke detectors have always been a bad idea IMHO. Low current
    smokes like the alarm industry uses, would reduce, or even eliminate
    that issue.

    Maybe it was the AHJ, or Fire Marshal who looked at the pretty smokes
    mounted 8 to 12 feet up, and saw a nice blinking light, and was happy
    with that as an inspection. Then, you never hear from these bozos ever
    again. If there is no financial gain, they could really care less. Let's
    be honest about it.

    They first required smoke detectors in the hall to adjoining bedrooms.
    Split bedroom plans required a smoke in each hallway. Now they require a
    smoke detector inside each bedroom, Heat Detectors in the laundry room,
    kitchen area, the boiler, the hot water heater, the air handler, the
    attic, the basement, the garage...CO Detectors, NG detectors, Flood
    detectors, fart detectors, This & That detector, only to increase the
    chance ten fold that of one of these devices may be faulty, or what say you.

    Yet the statistic haven't changed. Homes burn down just as quickly, and
    people still die of smoke inhalation, with or without these devices in
    place. I have no AC powered smokes in my home. In fact, I have Ademco
    wireless smokes & heats, and I also have 9v lithium powered smokes as a
    standby. One set has built in escape lights, and temporal sync sounders.

    Overall I would say that you are far safer with smoke detectors than without
    them, the chances of one of them failing and actually causing a fire is in
    my opinion, notwithstanding the link I posted, close to zero. I'd have to
    agree that the more smoke detectors you install, the more likely one is to
    fail, but then again the more there are the less likelihood there is of all
    of them failing. I certainly don't think AC smokes are inherently
    dangerous, anymore than an AC light fixture is inherently dangerous. The
    danger as I see it is the cheap smokes typically sold at the big box stores
    and installed by builders and homeowners alike, these things seem to alarm
    if someone cuts the cheese in the next street, IMO the sheer number of false
    activation's cause people to disable them to prevent nuisance alarms.

    There is one thing that we dont know...

    is it the 110 volt wiring that created the fire of the detector itself..

    We have to remember that poeple do remove there 110 olt detector from time
    to time and reconnect them after the steaks are done..

    One posibility is that the 110 volt alive wire could have been stuck between
    the electrical box and the smoke detector, and after some time , it shorted
    just enough to creat heat but not enough to trig the breaker..

    But I do agree with you, our low voltage detector would never cause a fire..

    In almost every case, the smoke detectors are disabled where the
    stove has no vent to the outside. It is a barefaced lie that stoves
    with charcoal filter fans are sufficient. Nonsense. It should be a
    crime to build a house with a stove that does not vent directly to the
    outside. Every disabled smoke detector I have seen is in homes where
    the stove fan does not vent outside. I don't even recall seeing a
    disabled smoke detector in a home where the stove fan is vented.

    Actually, IIRC the use of smoke detectors in homes has cut the
    fatalities in residential fires in half

    Could be they were 20 years old and never cleaned either.

    You dated yourself. Vacuum tube TVs with tens of thousands of volts
    and plenty of heat were routinely chock full of dust. Dust was not
    harmful and did not create fires. Dust remained because nobody wanted
    to stick their hand in there. Dust would not start a fire. So it was
    left inside hot, high voltage TVs.

    I've seen dust burst in fire in Ham radio linear lamp amplifier, Small fire
    that never did any wrong, but its because most of those amplifier were built
    in metal case to prevent RF from leaking out too much.. Lets think about a
    wooden case...what would happen...

    Yeah right, next you'll be telling us that no pigs are killed or harmed in
    the manufacture of ham radio's.

    LOL... You should go on the road Doug. :)

    Again, TVs running at tens of thousands of volts and that sometimes
    arced were chock full of dust AND routinely housed in wooden
    cabinets. Did you see dust start the fire OR see something else start
    a fire that also burned dust?

    That's tens of thousands of volts that arced in much heavier dust
    concentrations. The smoke detector had far less dust and only 120
    volts maximum. Dust did not start that fire.

    The dust bursted in flame after arcing of RF power....

    Most of those linear amp used a push pull configuration of 2 large tube...
    the voltage on the top of the tube is almost always 600 volt dc or more ,
    but the current is a lot more then what is in any TV..if you output 1000
    watt RF at the last stage of amplification that mean that you have at least
    2000 watt of power to produce it.. now at 1000 volt ,it mean 2 amp of
    current.. if this arc, there is more then enough current to start a small
    fire in the dust, but it clear itself in a few second cause dust dont burn
    much... so there was a puff of smoke a flash of light then all ways gone by
    the time you look at the linear..
