So, do they fit under normal light fixture covers, or not?

wootgoat wrote:You know... as ironic as this may sound, if these can last forever, they could prove quite useful. No more of those annoying beeps when there is a low battery, that's for sure. Even if it only lasts twice as long, that feature alone make it well worth it in my book. :-)

Possible solution: Put in an electical box next to an existing light fixture, and mount a smoke detector that works off the house wiring.

I picked up a pack of these at my local home improvement store. They seem to work fairly well for a while (but I have never had a house fire), but I have had some problems with high wattage bulbs meling the plastic case.

Thanks for those reviews- my husband instantly wanted these but needed to be reassured.

Now he's trying to decide if a smoke alarm is a good Christmas gift for people so he has an excuse to buy more.

?

Garage, laundry room, less finished spaces tend to have these types of fixtures. Most newer homes have recessed lighting but if you basement is unfinished you likely have some of these, or may have one in some kind of utility space.

Don't think it can be used in a Recessed Light either.

As the packaging says, this would work to protect "high-risk areas" such as laundry rooms, garages, furnaces and workshops -- typically places with bare bulbs.

Apparently not intended for the living portions of your house.

do these work with those energy efficient bulbs? (hope so)

or do they require a special bulb? (hope not)

I doubt it, since it's before the bulb: if the switch is on, and it works, this should get power. If it's defective or uncharged, I would suppose that the light bulb wouldn't work.

Hah. By "going off," I think spyderman4g63 meant whether the alarm will be activated (as in the sirens will sound). It's an interesting question since incandescent bulbs actually may actually burn out with a puff of smoke. Would that activate the alarm?

Ionization or Optical technology?

What if the fire starts at the lightbulb and fries the detector? Did someone already ask this?

lol I know what you mean- that definitely would have happened to me today.

OK- From the prod manual-

Test Your DuPontTM Smoke Alarm to Ensure
Correct Operation
a) Go to the light switch that operates the light
fixture into which you have installed your
DuPontTM Smoke Alarm PS-131. Ensure the light
has been turned on.
b) Turn the light off then on twice in rapid
succession (2 flips).
c) Your PS-131 will give out an audible (85db at
10 feet) test signal for approximately
10 seconds.

Also this is really only good for bare bulbs- garages, basements etc- where there is no shade- I am in for two- I have a few places I can use them- and I will wrap a few up for stocking stuffers for my kids as they have basements and garages also...thinking ahead

This idea just won't work for me; the smoke is unlikely to be detected in the glass globe around my lights, and it's already a tight fit in there with the compact fluorescents.

Lowerone wrote:Not so sure on that, unless you have 3 prong outlets on your ceiling. You know... where the smoke would be.

Not a very timely smoke alarm of it is placed vertically and two feet of the floor.

Unless it were in one's attic and the attic had no barriers between it and the rest of the house... and the airflow from the fire would lead directly to said attic...


What would happen if you screwed all 3 of these (in the set) into each other? Would they be louder (or rather, based on some scientific law - Ohm's maybe? - the one at the bottom of the set would be quieter since less electricity getting to it) or just more alarming?
I wonder if there's a way to tweak the frequency/pitch/sound of the alarms so they sound different in different areas of the house or for different owners... High pitches aren't as alarming to me, and my dad can't even hear some of them, whereas my mom goes ballistic at anything 2 octaves above middle C""

I actually own one of these.... They're pretty handy. I put one in the socket to the light in our washroom. I did so for two reasons: 1) Because we use that light all the time whenever we do wash and 2) In case the lint trap/exhaust pipe gets backed up with lint and catches fire.

I would only suggest you buy these if you plan on putting them in a socket to a light that you use often (otherwise it'll lose it's charge and beep at you.) Though all you have to do is leave the light to it on for like 10 minutes straight and it'll be ok for awhile.

Buy multiple ones, and make different chords out of them. Then add the switches and you've got a musical smoke detector!

NotGoddess wrote:Seems like a good idea, but all my ceiling lights have covers to hide the bulb- I don't see how one could use a cover with these so you would have a bare bulb sticking out.

Great for highest risk areas in your home such as laundry rooms, basements, furnace rooms and storage areas

Since they come 3 to a pack shouldn't we get 2 packages to make it a true 2FER?

terraguy wrote:Anyone know how long it takes to charge the battery in one of these things?

According to the manual, the light needs to be on 2 hours a week to keep it fully charged for a month, so to me that says 8 hours to initially charge it. Not bad.

MaureenJ8 wrote:These actually sound like a great idea, but is anyone familiar with how sensitive they are? I had to get rid of my last smoke detector because it went off every time I opened my oven (even with the fan on).

sounds like more of a problem with your cooking than with your smoke alarm to me... ;-)

So basically these need to be used somewhere with an exposed light bulb/socket --- and that light needs to be turned on for some period of time at least once each month to ensure the battery is recharged and ready to sound the alarm if there is smoke.

While that may work well in the basement, I don't turn the light on often enough in the attic to effectively recharge the battery.

Sort of... I was going the other way - literally - but it's still a good valid question.

ItsAaronnnn wrote:So how do they work when the fire burns the wiring leading to your home before it gets inside the home?

The device charges while the wiring is connected, and will hold a charge for at least 30 days disconnected...so unless you have an extremely slow-burning fire, I think you'll be safe-ish.

:D

Exactly. Alarming to everyone!

...and then the neighborhood dogs can join in, and everyone can join in the fun!

Awesome in concept. Useless for most apartment dwellers. No ceiling light fixtures anywhere except the hall way really. But I'm debating a set for my parents house. They have a few rooms it would be good in. And I think giving something like this as a gift shows you care about the person. Right? RIGHT??

drewy813 wrote:That looks pretty cool. But how long does that charge last on it?

"up to 30 days"

geo8rge wrote:Possible solution: Put in an electical box next to an existing light fixture, and mount a smoke detector that works off the house wiring.

In general, smoke detectors need to be high -- no more than 4" from the ceiling. So when you say light fixtures, make sure you're talking about ceiling lights, not sconces, etc.

On the other hand, you're more likely to notice a fire in a place you're in more often... so unless one lives in a garage or their laundry room, etc, it's a good place to have a bit of a warning so you can get clear of any danger.

How awesome would it have been for Sellout.Woot to have had fire extinguishers today? Unless they were refurbs, that would defeat the awesomeness.

gwaki wrote:Remember:

So can anyone tell me why I can't put this in a lamp that is on 1/2 the day? I know smoke rises and near the ceiling would be ideal for a smoke detector but wouldn't a lamp be better than nothing? I hardly ever turn the ceiling ligts on due to the ceiling fans. They don't have separate switches. Let me know your thoughts!

naclark wrote:Ionization or Optical technology?

To answer my own question: From the manual

Sensor Technology
Your DuPontTM Smoke Alarm PS-131 uses an ionizationtype
sensor to detect the presence of smoke. Ionizationtype
smoke alarms are generally more effective at
detecting fast, flaming fires, which consume combustible
materials rapidly and spread fire quickly. To increase the
level of protection you should also install photoelectrictype
smoke alarms that are more effective at detecting
slow-burning fires, which can smolder for hours before
bursting into flames.

Bumber I was hoping for optical as all my detectors are already Ionization.

looking at the picture the contacts for the screw in bulb are not continuous. I would guess it can only charge if the current flows through the bulb. A burned out bulb would interrupt the charging circuit. If the battery were charged, it should function but not recharge until the burned out bulb was replaced

Yes. Or you were so unimaginative in your gifting ideas that you found an excuse to buy something off woot just to "share"... Like last-minute Christmas shopping at Walgreens/CVS/SuperD (or whatever 24-hour pharmacy you have): you put the least amount of effort into thought, but the things you got tend to be useful, if not appropriate for "gifts".

Do any owners have an answer on this one?

Cool, these can save lives :D
