Answer: 
Yes. As long as the batteries are the same voltage (1.5v) as regular AA batteries. They should last longer.

Answer: 
It is not recommended because lithium batteries have a fast fall off rate at the end of their life and may not trigger the low battery warning on the alarm.

Answer: 
Short answer is no, it might work but you shouldn't do it.
The low battery detect will only work correctly with the alkaline batteries. When a lithium battery reaches the low battery voltage limit, the lithium is dead. The alkaline still has about 1 week of power left.

I do not know how the wireless feature is setup but the lithiums batteries do put out a slightly higher voltage and the wireless transmit may turn off because of that. I know of a Dell remote for their projectors that do this.
The batteries listed in the instructions were tested with the unit and are know to work with it. Read Less

Answer: 
Yes, BUT; There are different voltages of lithium batteries even at the AA size, so we can't say that lithium will or will not work in general. Specifically, the Energizer Lithium AA batteries run at 1.5v, just like alkaline AA's. Those will work great and last longer. Those are generally found in retail stores.

How susceptible to nuisance triggering are these alarms?

This question is from Battery Operated Wireless-Inter-Connectable Smoke Alarm
Asked by
Coeur d'Alene, ID

March 29, 2015
Most smoke detectors I have experience with tend to have a lot of nuisance alerts - a bit of smoke from cooking a meal, steam or aerosols from the bathroom, etc. In a multi-family dwelling, having everyone's fire alarm sound each time someone takes a shower would result in people disabling the detectors...

Ours go off for no reason at all - no shower, no cooking, frequently dusted. The false alarms result in skittish kids and frustrated, sleep-deprived parents, as they seemingly always go off at night. Maybe moonlight is the culprit?

If they do trigger you have the ability to temporarily hush the unit for a short time while things clear out. I have never put one in a kitchen or bathroom. We have them installed in hallways and bedrooms on each level as well as our dining area which is adjacent to the kitchen and basically the same room. However it is about 35 feet from the stove. We have had no nuisance alarm from this location. Our master bath is directly connected to the master bedroom. Our smoke alarm is just a few feet away from that door in the bedroom and we have never had it trigger from steam off the shower. Good location choices will help keep those nuisance alarms to a minimum. Read Less

Hello. In reference to your question, Smoke alarms are designed to minimize nuisance alarms. Combustion particles from cooking may set off the alarm if the alarm is located close to the cooking area. Large quantities of combustible particles are generated from spills or when broiling. Using the fan on a range hood which vents to the outside (non-recirculating type) will also help remove these combustible products from the kitchen. Kidde Wireless Battery Powered Smoke Alarm (model RF-SM-DC) has a HUSH® button that is extremely useful in a kitchen area or other areas prone to nuisance alarms. If the alarm does sound, check for fires first. If a fire is discovered, get out and call the fire department. If no fire is present, check to see if your alarm is in a location to be avoided as this may have caused the alarm. In rare occasions, interference from other electronic devices may cause nuisance alarms. There are certain locations to avoid to avoid nuisance alarms. You will want to avoid putting the alarms in the garage. Products of combustion are present when you start your automobile. Avoid putting your alarm in an area where the temperature may fall below 40ºF or rise above 100ºF, such as garages and unfinished attics. Aviod dusty areas. Dust particles may cause nuisance alarm or a failure to alarm. In very humid areas, moisture or steam can cause nuisance alarms. Insect-infested areas can also cause nuisance alarms. Smoke alarms should not be installed within 3 ft (.9m) of the following: the door to a kitchen, the door to a bathroom containing a tub or shower, forced air supply ducts used for heating or cooling, ceiling paddle or whole house ventilating fans, or other high air flow areas. Normal cooking may cause nuisance alarms. If a kitchen alarm is desired, it should have an alarm silence feature or be a photoelectric type. Avoid putting the alarms near fluorescent lights, amateur radios, electrical equipment or other devices known to transmit an RF signal. Electronic “noise” may cause nuisance alarms. Avoid large metal surfaces and bundles of wire. The best way to avoid nuisance alarms is to clean them at least once a year. To clean your alarm, remove it from the mounting bracket. You can clean the interior of your alarm (sensing chamber) by using compressed air or a vacuum cleaner hose around the perimeter of the alarm. The outside of the alarm can be wiped with a damp cloth. After cleaning, reinstall your alarm, verify the green LED blinks every 10 seconds and test your alarm by using the test button. If cleaning does not restore the alarm to normal operation, please call us. For more information, you can call us at 1-800-880-6788. Thank you for your interest. Read Less

You have the ability to have multiple devices all interconnected. When an alarm is sounds, how do you determine where the alarm originated or which device you should go to first?. Example: It could be in your garage, but you go to the basement, you could then be going from place to place to determine what has to be done, and could be too late.

Answer: 
First, exit the house. That is most important. Get everybody (and pets) out and call the fire department before you try and figure out which alarm is sounding. The initiating alarm will flash it's Green LED. Receiving detectors will flash their Red LED. It might be best to let the firemen figure out which is alarming if there is any smoke evident.

All the alarms will sound together, the red LED always flashes in conjunction with a sound. However, the green LED will flash every second (instead of every ten seconds) while the alarm is sensing smoke. So those alarms sensing smoke flash their green LEDs and the others don't.

Furthermore, after the alarm condition is over, the unit(s) that caused the alarm will continue to flash until the test\reset button is pressed. That can be useful for troubleshooting false alarms or intermittent conditions.

These devices will not notify you of the area alarming. To know the area that is alarming you will have to install an addressable system. These devices are mainly found with a security system in a residential setting and a stand alone fire system in a commercial setting.

Rated 4.8 out of 5 by 78 reviewers.
Rated 4.0 out of 5.0 by Good Product with Disappointing Feature Easy to install, but has an LED that flashes frequently to indicate it is OK. That's very annoying in the bedroom. Really? They needed that feature? How about a button to test if it's working? Oh, wait, it has one of those already, so the LED is totally unnecessary. Had to go low tech to solve it - covered the LED with two strips of duct tape. The LED is only mentioned in the middle of the instruction booklet so there is no way you would know it was there from the packaging in the store - really bad marketing/advertising. So good unit, but recommend not putting it in sleeping areas. August 30, 2016
Rated 5.0 out of 5.0 by Great idea these smoke detectors Back in March of this year there was a fire in my basement. My bedroom is two stories above the basement. I had a working smoke detector outside my bedroom door. When the smoke detector went into alarm, I could not hear it. My wife however did. Think about it, how long a fire two stories below, how long it had to smolder and burn before smoke got up to the 2nd floor. My wife and I were displaced for over 4 months. While displaced, I noticed the extended stay had a hard wired interconnected smoke & fire protection system. I wondered if there was such a system for residential use, but only wireless. I did my research and found that yes there is and they were available at Home Depot. Now I have one detector on each floor level, and one in each bedroom. In the event any of the interconnected detectors goes into alarm, they all sound an alarm. August 9, 2016

Rated 5.0 out of 5.0 by Wireless Smoke Detectors work great! We paid over $1000 to hard-wire three smoke detectors in my son's condo - not to mention the drywall damage we had to repair - so when we purchased an older home that had NO smoke detectors in it - we cringed. This was a perfect solution and only cost us $249 for 10 with the promotion! They were relatively inexpensive and VERY easy to install. When triggered they ALL go off as if they were hardwired together. We highly recommend this product! January 6, 2015

Rated 5.0 out of 5.0 by Very Nice I installed 5 of these and 1 hardwired one ( to replace my existing 10 year old hardwired unit ) . Easy to install and they all work as they should. I see a few reviews of false tripping and/or chirping. I'll just wait and see what happens. I can't remember ever having my old one or the one before that every going off unless I was testing them with smoke !! Optimistic ( Tip: Using the supplied plastic anchors,::I almost never use a drill to make the holes. I use a sharp awl to start the hole then locate the proper diameter Phillips screwdriver and twist it in to the drywall to make the hole) You do all this gently to avoid maybe hitting a piece of romex, water pipe, fire sprinkler pipe etc..
