Smoke detectors - Ionization vs. photoelectric

[Wayne02]

I need to replace the smoke detector in my house and the one in my RV, and as usual these days there is not just one type to consider.

As near as I can tell the ionization type is better for detecting 'invisible' smoke such as that which would come from a fire that is rapidly consuming combustibles. Something like waste basket burning rapidly or a kitchen grease fire. Ionization types are less expensive and more prone to false alarms.

Photoelectric detects visible smoke and is better for detecting slow burning smoldering fires.

And they probably make detectors with both.

Seems like the kitchen would be a likely area for a fire to originate from, eh? Especially with my cooking.

So what type do you have?

Ioniation detectors work quite well and are the lesser expensive of the two.

I'd avoid putting one in the kitchen as you most likely WILL set it off repeatedly, thus if there is ever an actual fire, it will be like the Boy Who Cried Wolf. That (and much worse) you will take it down when cooking and forget to put it back.

Don't forget about a fire extinguisher, as well. These need to be replaced about every six years, depending on the type.

Just my .02.

If you live in Iowa the problem will be solved for you courtesy of the government!
As of 10/01/09 all smoke detectors, new and replacements, must be the dual source type.

In typical government action it was to occur on 10/01/08, but has been set back several times.

The government is here to help you!
All choices are to be made for you!

I just replaced 6 fire detectors, hell I am not sure what they are, just used the firex replacement, that plugs in, and uses the same mounting bracket

I don't know what the difference is, but when you buy one for the RV, don't forget a CO detector. Some units detect both smoke and carbon monoxide, so you only have one set of batteries to change. I have one in the truck, but I have no idea what kind it is.

Just like with shooting, placement is key with either kind of smoke detector. Be sure to follow the instructions on where to mount them.

While smoke rises, CO is craftier. It basically goes wherever the air currents take it. Sometimes that means it rises, sometimes it means it sinks. Not a bad idea to mount an extra CO detector or two a few inches off the ground. There are good CO detectors that plug into outlets. Since there are usually outlets down low on walls that's a good place.
