Product description

The First Alert SA511CN2-3ST Interconnected Wireless Smoke Alarm with Voice Location features an 85-decibel siren and voice alarm that tells you where the danger is located. A photoelectric sensor detects smoke while minimizing false alarms from cooking or shower steam. Interconnected smoke detectors in different locations are designed to work together, with one alarm triggering the other alarm during a fire, helping to provide the earliest warning for your family.

From the Manufacturer

In the event of a fire every second counts. If a fire were to begin in your basement and the alarm there sounded, you may not hear it right away if you're sound asleep two floors up. With traditional battery-operated alarms, you lose valuable time waiting for the smoke to rise to another alarm, on another level, before the alarm on your floor sounds. But with First Alert ONELINK alarms, if one detects danger, they all sound. This can alert you sooner, and it increases your chances of getting out safely. Until now, alarms that could signal each other were only available in homes with hardwired alarms requiring installation from an electrician. But First Alert ONELINK alarms communicate without wires. ONE Link-with Voice Location Smoke alarm is programmable with up to 11 locations in your home - when alarm sounds it will tell you the location of the smoke. The wireless feature allows multiple alarms to talk to each other - when one alarm sounds, they all sound. The wireless network operates on 914 MHZ 3 channels and will not interfere with other electronics. The ONELINK smoke alarms uses photoelectric sensing technology which is environmentally friendlier and which reduces nuisance alarms, making it ideal for cooking areas. It is also great for sensing slow smoldering fires quickly. A low battery signal alerts you to replace the battery. The test/silence button both silences a non-threatening alarm or low battery warning and allows you to test the unit's functionality. The AA batteries are easy to install in the convenient pullout battery drawer. Two AA batteries included.

• Help keep your family safe with these battery operated smoke alarms that wirelessly interconnect with each other and other First Alert enabled alarms so that all sound when one is activated, creating a home safety network; comes in a pack of 2 alarms
• Voice alarm with 11 programmable locations tells you where the danger is so you can choose the best evacuation route; Loud, 85-decibel siren sounds to alert you to danger
• Equipped with photoelectric smoke sensor optimized to detect larger smoke particles produced by smoldering fires; Helps minimize the number of false alarms
• Battery powered alarm requires no rewiring for installation and provides continued monitoring even if there's a power failure; use with Polaroid AA batteries for best results
• Wirelessly connect upto 18 first alert enabled alarms for the maximum in whole home protection; includes test/silence button, low battery warning, end of life timer
• First Alert has been the most trusted brand in home safety since launching the first residential smoke alarm in 1958 (Based on a First Alert Brand Trust Survey in February 2018)

User questions & answers

Question:	is the wireless signal constant or only during an alarm
Answer:	No, they are battery operated. The 9 volt batteries are included with the alarms.
Question:	Can i pair these smoke detectors with the co/smoke detectors of the same brand (firstalert). i don't need everywhere co detectors which cost more
Answer:	No, they are battery operated. The 9 volt batteries are included with the alarms.
Question:	What is the max distance the units can be apart and still communicate with each other
Answer:	I bought one in 2012. I have changed the batteries once, about five years ago. Thought it was due for a change now but it has reached the end of its ten-year "life" after seven years. To be fair, the sticker indicates it was manufactured in April of 2010, so it was on a shelf for two years, making it nine years old.
Question:	If i buy three of these double packs will they all connect
Answer:	I’m using these to replace the wired units from the same manufacturer. They fit the same mount. Two units never worked right, and a third less than seven years old just stopped working. I don’t know if they were wired properly or not to begin with, so I’m going with these ones.

User questions & answers

Question:	Is there a way to get the power supply to also hardwire these
Answer:	I suppose the battery life would depend upon how often it is used. I open my safe rarely but some might do it daily, thus affecting battery life. On the outside of the lock, there is a rubber-covered set of contact to which a 9-volt battery can be applied. This will allow the mechanism to be activated should the internal batteries be depleted. The key, by the way, is used as an additional lock but is optional. The electronic lock must be used. The key cannot be substituted instead of the electronic lock. The electonic lock is always in effect. The key is additional locking and if locked, the electronic lock alone will not open the safe.
Question:	Works on 220v
Answer:	Metal.... great safe, holds a lot - we purchased another tray for small iteams and it did not hinder the space at all...
Question:	Why does it say in the Technical Information that batteries are not required
Answer:	Yes, I too found the safe puzzling to open.
Question:	I do not see onelink anywhere on the unit. will this link with my older first alert onelink units
Answer:	My recollection is that the factory code is unique per safe. I'd suggest contacting the company. They may be able to help.

User questions & answers

Question:	My entire home is equipped with BRK smoke detector (4120 B) and Carbon Monox Det (CO50120B). They need replacing. Will new BRK fit extant casings
Answer:	Yes all the wired Nest Protect needs is the 120V hot (black) and neutral (white) wires in the electrical box connected to the plug-in pigtail that comes with the Protect. If your house has multiple detectors now you will usually also find a red wire in the electrical box that interconnects your old detectors so that if one goes off they all sound. That wire is no longer needed with the Protect so you just cap it with a wire nut.
Question:	can these be connected together so if one is set off they all go off
Answer:	Yes, but only if you are connected to the internet and then only for the last ten days, and only if the level rises above the heads up level (which is 70ppm and rising for around an hour or a shorter period if over 150ppm). To counter what someone else's answer was - Carbon monoxide does NOT sink. It is in fact lighter than air (CO has an atomic weight of 28 versus Nitrogen (N2) which is also 28 - but marginally heavier (by 0.003 amu due to heavier isotopes), Oxygen (O2) which is 32 and Argon which is 40. However the weight is similar enough in the air in your house that it tends to distribute as a fluid and is measurable anywhere in a room; it really depends upon how air moves through the space. The levels tend to fluctuate rapidly as CO distributes and any outside air mixes in and additional CO is added. Overall, there is no perfect way to measure the CO levels with one device in one place, but this is as good as most people need.
Question:	How does the Alarm Latch feature "easily identify initiating alarm"? This is major problem with false alarms on my existing Kidde/Firex dual alarms
Answer:	I just checked this for you. I unplugged my wifi router and started a test. All detectors alarmed as expected. So, yes, the system works even without active wifi.
Question:	Can a BRK Model 92120B smoke detector directly plug in and replace an old BRK Model 4120B smoke detector (without an adapter
Answer:	I think very few here understand the question. National code requires interconnected smoke detectors as of 2004, there is an extra wire in the circuit and all smoke detectors are on that wire for 'signal'. When one alarms they should ALL alarm. If I am reading the answers correctly, NEST does not comply with the signal wire. However, it looks like it does set up its own wireless network to act like they are all interconnected. To be honest, after paying for the extra wire behind the wall, why would I want to by 6-8 nests at $100 each when the originals are 20-30 each? This way there is one smart point to notify if any detector is going off. Nests way 6-9 smoke detectors, 6-8 login, 6-8 ip address. Ugh, what a nightmare!

User questions & answers

Question:	How do these talk to each other? Are there wifi frequencies or radiation
Answer:	Nothing can turn it off. Ours went off at 4am for no reason and wouldn’t turn off for anything. There was no heat, no smoke, we held the button, took our battery. Still trying to find instructions online and can’t find anywhere.
Question:	When hardwired, will they all announce their location or only the room that triggered the entire system
Answer:	The instructions firs said to place it on the ceiling, but later mentioned using a wall. The mounting plate has a screws as well as a sticky pad that is magnetized on the other side to attach the alarm to. The sticky pad was not strong enough to hold, so the screws are necessary as well.
Question:	If there are two - living room and bedroom. does the bedroom one say "fire detected in living room" or is it local only for voice location
Answer:	Not to my knowledge
Question:	Do the voice models have alarm and voice? Or just voice
Answer:	Complies with California state fire marshal (CSFM)

Product description

The First Alert SCO5CN Combination Smoke and Carbon Monoxide Alarm features dual sensors to detect both smoke and carbon monoxide in a single device. A photoelectric sensor detects the smoke most often produced by smoldering fires, and minimizes false alarms from cooking smoke or shower steam. Additionally, the advanced electrochemical CO sensor detects carbon monoxide leaks from multiple sources, such as faulty fuel burning appliances, blocked chimneys, and generators running inside or too close to homes. A loud, 85 decibel siren alerts you to the threat; unique alarm sounds and indicator lights on its face distinguish a smoke warning from a carbon monoxide warning. This carbon monoxide and smoke detector is battery operated, so you don't need an electrician for installation. Requiring just two AA batteries and featuring an easy access battery compartment for quick changes, this smoke and carbon monoxide detector has a single button that allows you to silence a false alarm or test the unit.

Carbon monoxide (CO) is the leading cause of accidental poisoning deaths in America, yet many people don't know they are suffering from CO poisoning until its too late. Since symptoms of CO poisoning are like the flu, you might not even know you're in danger at first. That's why a carbon monoxide alarm is an excellent way to protect your family. It can detect the CO you can't see, smell or taste in the air.

The First Alert SCO5CN carbon monoxide and smoke alarm uses an electrochemical carbon monoxide sensor-the most accurate technology available. The alarm uses photoelectric smoke sensing technology which is environmentally friendlier and which reduces nuisance alarms, making it ideal for cooking areas. It is also great for sensing slow smoldering fires quickly. The permanent sensors last the lifetime of the alarm. The test/silence button both silences a non-threatening alarm or low battery warning and allows you to test the unit's functionality. A low battery signal alerts you to replace the battery and end-of-life alarm of three chirps alerts you to replace the unit. Two AA batteries are included. 5-year limited warranty. UL listed. Not available for sale in Massachusetts.--Bree Norlander

User questions & answers

Question:	pack is $30, 2 pack is $90. Why is a two pack so much? I thought the idea was to incentivize more product at a lower cost. This is halarious
Answer:	I no longer live in the apartment where I replaced the old smoke alarm, but you will love this one. It's so nice to flip the battery holder down and not have to remove the battery from the unit.
Question:	Advice on false alarms? Goes off every week or so. It's in our kitchen/living room, but goes off even when we are not cooking. Goes 1 min then stops
Answer:	No
Question:	I have these througout my house and rental unit. Installed them about 7 years ago and many malfunctioning. Any durability mprovments since 7 yrs ago
Answer:	The instructions that come with the unit duplicate what I have read from several Fire Department sources: you can place your unit on the ceiling, but AT LEAST 4 inches (10cm) from the wall. If you want to mount it on the wall, mount it MORE THAN 4 inches (10cm) BELOW the ceiling, but NO LOWER than12 inches (30cm) below the ceiling. It has to be high enough up the wall to "smell" the smoke, but that 4 x 4 inch (10cm x 10cm) area where the wall meets the ceiling can sometimes harbor a "dead zone" of still air where the smoke would NOT reach the detector quickly enough during a fire to warn you in time. Thus, do NOT mount your detectors too close to where the wall meets the ceiling.
Question:	How long do batteries last
Answer:	Ionization type. I actually looked at at manual to be certain.

Product description

Battery Operated Wireless Smoke Alarm, Quickly & Easily Install An Interconnected Alarm System, Includes Ionization Sensor, not available to members in Oregon. This product adds a great value. Product is highly durable and very easy to use. This product is manufactured in China.

The Kidde 0919-9999 Battery-Operated Wireless Smoke Alarm allows for the easy installation of an interconnected smoke alarm system without the high cost and hassle of rewiring your home. The alarms are wirelessly linked so that when one alarm is triggered, all alarms will sound. This alarm can also be placed in a detached workshop or shed and linked into the home's interconnected system.

Experts recommend interconnected alarms, because when one sounds, they all sound, providing an early warning against fire by dramatically increasing your ability to hear an alarm anywhere in your home, regardless of where the fire starts. Newer homes are required by code to have interconnected alarms. Wireless technology now enables any home to have an interconnected system.

This alarm uses ionization sensing technology. Ionization sensing alarms may detect invisible fire particles (associated with flaming fires) sooner than photoelectric alarms. Photoelectric sensing alarms may detect visible particles (associated with smoldering fires) sooner than ionization alarms. Kidde strongly recommends that both ionization and photoelectric smoke alarms be installed to help insure maximum detection of the various types of fire that can occur within the home.

Choose the Right Wireless Alarms for Your Home

Kidde offers two wireless product options: a Battery Powered Smoke Alarm, and an AC Powered Smoke Alarm. These products enable you to customize your system based on your specific needs. Read below to see which Kidde wireless smoke alarms are best for your home.

Getting Started with Wireless Interconnect in Three Easy Steps

Step 1 - Determine the type of smoke alarms currently installed in your house.

1. Battery Powered

No wires; runs only on batteries.

Most older homes have battery-powered smoke alarms. These alarms have no protruding wires and are battery powered.

2. Hardwired

Runs on your home's electricity and may have battery backup. Only one alarm sounds when test button is pressed.

If your home was built in the last 20 years, you probably have hardwired smoke alarms. If only the alarm that you test sounds, then you do not have an interconnected system.

3. Interconnected

Runs on your home's electricity and may have battery backup. All alarms sound when one test button is pressed.

Homes built in the last 15 years may have an interconnected smoke alarm system. If all alarms sound when you test, you have an interconnected system.

Step 2 - Decide how many alarms you need in your home.

The NFPA recommends at least one smoke alarm on every level of the home and in every sleeping area.

Step 3 - Based on your home's current alarm set-up, decide which Kidde Wireless alarms to purchase.

1. If your home has only battery powered alarms:

Purchase enough Kidde Wireless Battery Powered Smoke Alarms (0919-9999) to replace all of your current smoke alarms. You will also have the ability to add Kidde Wireless Battery Powered Alarms in additional rooms for expanded coverage.

2. If your home has only hardwired smoke alarms:

Purchase enough Kidde Wireless AC Powered Smoke Alarms (1279-9999) to replace all of your current smoke alarms. You will also have the ability to add Kidde Wireless Battery Powered Alarms in additional rooms for expanded coverage.

3. If your home has interconnected smoke alarms:

Purchase one Kidde Wireless AC Powered Smoke Alarms to replace one current smoke alarm. Kidde Wireless Battery Powered Alarms can then be installed in additional rooms.

Interconnectable for Improved Safety

Fire and consumer experts recommend interconnected alarms for added protection. According to the National Fire Protection Association (NFPA), most Americans feel they are more at risk of being a victim of a tornado than of a house fire. Actually the opposite is true. Fires are more common than any other disaster that strikes a family at home, and can become deadly in minutes.

You have on average less than three minutes from the time you hear a smoke alarm to escape a fire. The sooner you hear an alarm, the sooner you can get out safely. Smoke alarms that link together so that when one goes off, they all go off, are called interconnected alarms. These alarms provide more warnings in more places, giving your family more time to escape a house fire. Houses built after 1993 are required by building codes to have interconnected alarms that are wired into their electrical system.

Trademarked Hush Feature for Convenience

By pressing the Hush button, you can easily and safely silence nuisance alarms caused by non-emergency situations, such as overcooked dinners.

This alarm's Smart Hush feature has the capability of temporarily desensitizing the alarm circuit for up to 8 minutes. This feature is to be used only when a known alarm condition, such as smoke from cooking, activates the alarm. The smoke alarm is desensitized by pushing the Test/Hush button on the smoke alarm cover. If the smoke is not too dense, the alarm will silence immediately. The red LED will illuminate for 1.5 seconds every 8 seconds while in hush. This indicates that the alarm is in a temporarily desensitized condition. The smoke alarm will automatically reset after approximately 8 minutes and sound the alarm if particles of combustion are still present. Smart Hush can be used repeatedly until the air has been cleared of the condition causing the alarm. Pushing the Test/Hush button on the alarm will end the hush period.

3-AA Batteries, Indicator LED, and Test Feature

Because a smoke alarm only helps protect you if it's working, this unit features a red LED that flashes every 10 seconds to indicate that it is operating correctly. For additional peace of mind, the alarm also contains a test/reset button that enables you to periodically test its circuitry and horn.

The alarm's 3-AA batteries provide continuous protection against smoke and fire hazards, even during power outages. The unit offers a low battery warning that issues a brief chirp every 30 to 40 seconds for at least seven days before losing power, letting you know that it's time to change the battery.

This alarm is UL listed, so you can be confident of its quality, and it is backed by a 10-year limited warranty that lasts the life of the alarm.

From the Manufacturer

There are only minutes to escape a house fire. The sooner you hear the smoke alarm, the sooner you can get out safely. Kidde interconnected Ionization smoke alarms provide early warning against fire by linking together the smoke alarms in your home, dramatically increasing your ability to hear an alarm anywhere, regardless of where the fire starts. The Kidde Wireless Smoke Alarm enables families to quickly install an interconnected smoke alarm system throughout their home without the mess of rewiring or cost of labor. Interconnected smoke alarms provide an earlier warning to fire because they link together so that when one alarm sounds, they all sound. This provides more warning in more places, and gives families more time to escape. This battery-powered alarm links with other alarms and components of the Kidde Wireless System to create a customized, advanced fire protection system. It even can be placed in a detached workshop or shed and linked into the home's system. Install UL listed smoke alarms on every floor of your home, in hallways, inside bedrooms and outside of sleeping areas. Replace smoke alarms every 10 years. Ionization sensing alarms may detect invisible fire particles, associated with fast flaming fires sooner than Photoelectric alarms. Studies show both types will effectively detect either type of fire. For optimal protection, install both smoke alarm technologies in your home.

• Enables quick and easy installation of an interconnected smoke alarm system without messy wiring or labor. Temperature Range: 40 degree Fahrenheit to 100 degree Fahrenheit
• When one alarm sounds, they all do: wireless technology uses radio frequency to both transmit and receive messages about a hazard in the home
• Battery power enables homeowners to install interconnected alarms without rewiring
• Smart touch button quickly and temporarily silences nuisance alarms
• Wireless alarm can be installed in a detached workshop or shed. Humidity Range-up to 85% relative humidity (RH)
• Low Battery Indicator – Smoke alarm will chirp in the event of a low battery.

User questions & answers

Question:	Kidde strongly recommends & my fire code requires installing both ionization and photoelectric detectors. Is there a compatible photoelectric one
Answer:	I was thinking, if you do find a wireless photoelectric detector, especially one by Kidde, it should work perfectly as you can adjust frequency on each alarm, obviously so a neighbors doesnt match yours as well as for reasons of interference. If you find one, I suggest purchasing one to begin with to test the compatibility. The communications shouldn't be any different in them. Im not sure if you found one already and are just not sure of the compatibility or you simply can't find anything of the sort.
Question:	If there are several Kidde wireless smoke alarms that are tested, do each alarm have to be reset individually
Answer:	No, resetting one will reset all of the others you have in your house.
Question:	Does Kiddie (or anyone) have battery interconnected dual (ionization and photoelectric) smoke alarms? If yes, who
Answer:	There is a company that sells the highest tech smoke alarm,I've seen them they are interconnected,longer lasting,patent protected technology,but very costly,approx $ 600 per head,I called the company to get them to lower there price and save more lives,didn't happen try this web: www.homefiresafety.com or 1-800-825-5880
Question:	do you need to wire it
Answer:	No, these are wire.less units running off AA batteries. You just screw he substrate to the wall/ceiling, install the batteries, setthe channel and you are doe. The included directions are very easy to follow.

Answer:	They are white with a red plastic dust cover. The red plastic dust cover is for use when you are painting or remodeling to prevent particulates from entering alarm and setting it off.
Question:	The photo for this product indicates that this is a dual alarm (both p and i are shown on front of unit). Just supposed to be just photoelectric
Answer:	Yep, they are showing the wrong picture. This is a photoelectric model only. The dual ion/photoelectric hardwire detector is BRK 3120B. I realize your question is old....I'm answering it for others...
Question:	I have 20 year old First Alert alarms with incompatible wiring. Does this unit come with a new wiring harness to connect to the AC line

Smoke Alarms

Place at least 10 feet from kitchen/stove, and on the ceiling or high on a wall, no more than 10 inches from top.

Carbon Monoxide Alarms

Carbon monoxide alarms can be placed anywhere, not just the ceiling or high on a wall. They should be replaced every 5 to 7 years.

Fire Extinguishers

Keep in the kitchen and garage, but make sure to have the right grade for the type of fire that might occur.

Escape Ladders

Have at least one if your home has more than one story. Each room needs 2 escape routes; in most bedrooms it's the window, so have a ladder nearby.

User questions & answers

Question:	Is this the unit that was recalled for not detecting smoke
Answer:	so after fighting with it, i believe the answer might be smoke alarms? the octagonal shape with sides that are parallel to the battery case appear to fit into smoke alarms while the hexagonal (also on Energizer) do not. particularly First Alert/Intertek model SC9120B
Question:	how long do the batteries last
Answer:	Duracell components and batteries are produced at several locations in the U.S. and abroad, including Europe and China. If you have additional questions please contact our Customer Relations team at 800-551-2355 between the hours of 9am and 6pm EST.
Question:	Why can't this be shipped to area code
Answer:	Usually a 2 year lifespan from the date of manufacture. I have always had good luck with Duracell lasting the longest, more than the bunny claims!
Question:	does it have a siliene button
Answer:	It's the date usually found on the btry. On my last purchase of Duracell 9v coppertop btry's MAR 2015 is printed on the btry. The package, while it has no good to date on it says it is guaranteed fresh for 5 years. On this packaging you can not see a good to date on it until you open it and look at the btry. Therefore since it is gtd for 5 years I believe the manufacture date was 2010. Using a top rated btry like Duracell we change smoke alarm btrys every 2 years contrary to the suggested 1 year time frame of replacement. We also check the alarm function every month. We also use these 9v btry's in our garage door openers. Hope this answers your question. LR
