I searched Amazon.com over &amp; over and I see no mention if the smoke alarm is either the 'photo-electric' or the 'ionization' type! Which is it? Thanks

According to the instructions, this device is ionization. I believe a photo would cost more as well.

No it does not. I use my grill frequently and have never had an issue with smoke alarms.

Sorry dont no about that,cause we just drilled holes and put it in a different place than our smoke alarm.we never owned one of these before..sorry couldn't help

Absolutely, we replaces Kidde 1275's with the replacement number and bought the contractors pack which gave us one more smoke alarm [6] than we needed [a spare?] The new model looks slightly different and the flange that goes in the wall is larger. So....we left the old flange [it is almost hidden by the new alarm] and just unplugged the old and plugged in the new; tested them and they are working. The contractor's pack of 6 is a savings over buying them individually. ALSO, they come WITH Lithium batteries that are expensive so AMAZON is a great deal for these smoke detectors. I searched other sites and stores for months.

It's not a smoke alarm, it's a carbon monoxide alarm.I can tell you I know mine worked because at 4am when me and my girlfriend were sleeping the alarm went off and saved our lives. Also when the fire department showed up the sensor gave the same reading as the sensors they brought. I went and bought 2 more the next day.

All the test button does is check the BATTERY. It does NOT check the smoke sensor. They all say to test the sensor by using a can of 'smoke detector test aerosol'. Why not the real deal like real life smoke/fire I do not know nor understand at all! I find it worrisome.

the 2 old units I replaced were Lifesaver Model 1255 - I think most units are standardized to communicate over the 3rd wire so all alarms connected together sound when any one goes off. If you don't require that feature, I think any standard 2 wire unit can replace any other. See this link to help in deciding if you want photo or ion (or the combo unit I bought) https://www.nfpa.org/safety-information/for-consumers/fire-and-safety-equipment/smoke-alarms/ionization-vs-photoelectric

it does not set off the smoke alarm,the Oxy or C dioxide or mono alarms.There does is an aroma with it, which I have found is not that bothersome when I burn a candle.This is I guess that 1% that is note, it does say "I think" 99% ventless, I do love mine as using it does reduce the overall heating cost, on med it heats most of the 3 bedroom house.The blower works good and I am happy with it.....

In our home we have a group of 6 smoke alarms, 2 of them being carbon monoxide detectors. They connect up to the wiring all the same, any way the ones I have replaced do, the smoke alarm/carbon monoxide detectors just preform more function.

It acts as a switch for the circuit in your panel. When it detects smoke/heat it will close the circuit permiting line voltage to set off your alarm.

Jim, I'm not totally sure what you are asking, but the unit is all safe contained and is powered by a 9v battery. The same battery that is in smoke alarms.

You need an exhaust fan or run it outside. I tried running it inside and set off all the smoke alarms lol. Now I put it outside.

This is a hard-wired alarm w/ battery backup. For a dual alarm powered only by battery, look for First Alert SA320CN Double Sensor Battery-Powered Smoke and Fire Alarm

These are designed to connect to each other not to other brands and types of alarms. We have other existing units which will be triggered their own by smoke but will not chain react with the kiddes. The units are bought of same brand and set up to trigger each other from a different part of house or close houses , garages or sheds...So a garage unit could alarm in your home to notify you if as soon as a fire was causing smoke and before your car burned up.

any high quality, i.e. duracell or energizer alkaline battery, just remember to replace it before it starts to beep. When you wait for it to start beeping, you usually pull the battery and don't immediately replace it, which defeats the purpose of a smoke detector. I change mine with fall daylight savings time.

You have to reset the main panel if this device detects smoke/heat. It is not a standalone unit that can be used without an alarm panel.

Specifically for the Kidde p12040 the sensitivity is 2.28+/-1.08%/ft.If you are asking what the numbers mean, the detector measures smoke by detecting how obscure the air has become. Perfectly clear air is 0% a wall is 100%. For this detector, you should expect that if a light is 22' away from you when it goes off, you'll see only half (50%) of it's normal light output. This detector is photoelectric type, ionization type detectors are more sensitive (0.8 - 1.35%/ft). However, this ' better' sensitivity does not always translate into faster detection of all fires. A good choice would be to pick a combined unit that uses both ionization and photoelectric technologies, especially in kids bedrooms.
