User questions & answers

Question:	What is the manufacture date on these items
Answer:	Hello. Yes, but not the way you mean. When the alarms go off, there is always one alarm going off and setting off all of the others. This alarm will have a green light flashing every second as well as the red light. You have to identify that alarm and either put it in HUSH mode or unplug it and take it down to stop the others. This is intentional so that if you are not leaving the house then you are identifying and investigating where the smoke situation is and if there is danger. The HUSH mode will make the alarm require more smoke to go off and for a small amount of smoke will stop it for about 8 minutes If there is too much smoke, the HUSH mode will not stop the alarm for going off.
Question:	If the alarm goes off, how can you tell whether it's due to CO or fire if there is no voice alert
Answer:	Hello. Yes, this alarm comes with a wiring harness connector.
Question:	Because its a combo alarm where is the best place to install it since smoke rises and carbon monoxide doesn't
Answer:	Hello. The answer is no, the battery is only a temporary back up. If you want an alarm that is battery only, you will want our KN-COPE-D.
Question:	Why does this model contain the radioactive part? I am sure you are going to tell me that it is a trace amount and that it has all approvals
Answer:	Hello. When plugged in AC power, it is supposed to have a solid green LED light. When running on battery alone, it should have a green light that flickers every 60 seconds. If this is not what is happening, call us when you are on location with a ladder at 1-800-880-6788 so we can figure out what is going on and how we can resolve this.
Question:	When these are interconnected with other units, can hushing one of them hush all of them? Some of mine are in places that are hard to get to
Answer:	I paid FOR for 6 and only got 4. It’s listed as 6. I had to buy two more from Home Depot. DO NOT BUY THIS ITEM.
Question:	does it come with the hardwire connector
Answer:	Does not connect to hard wire. Only battery
Question:	Do you have to hardwire it in? Can it run on just the battery
Answer:	I just checked 2 of them, and am unable to locate that information.
Question:	How do you tell if it is working properly. Is it supposed to have a constant light
Answer:	The back cover comes off install battery and replace

User questions & answers

Question:	Can these be used for a pool alarm
Answer:	Both but first it send the SMS then it will call
Question:	Can buy six of these, or a single one plus the five pack
Answer:	Both first it will send SMS then it will Call you.
Question:	The pictures are very misleading it says it comes with 5 what shows 12 in the description it also says it comes with a keypad but doesn't show it in t
Answer:	Yes. There are various delays you can set via the "programming codes" listed in the manual. I know you can set an "alarming" delay (basically an entry delay). As for the other respondent that returned it because you can disarm without a code, that's the default behavior but can be changed using another "programming code" in the manual. Admittedly, the manual is not easy at all to understand but after a bit of tinkering, it looks to work like most other alarms except only requires $5/month text only service vs. $15-30 service to get notified about alarms. It was the only option that used 12v, GSM, and very little power and therefore I plan to utilize on my RV off of 12v battery power to protect it while stored.
Question:	Do they work independently? Meaning are they linked to each other
Answer:	Hello. This main panel have back up battery. If someone cut the power. Still can use 10 hours

Product description

The First Alert SC7010B Hardwired Combination Photoelectric Smoke and Carbon Monoxide Alarm with Battery Backup delivers both smoke and carbon monoxide detection in a single unit. Equipped with a photoelectric sensor and Optipath 360 technology, the alarm detects smoke produced by smoldering fires while keeping false alarms to a minimum. The unit also features an advanced electrochemical sensor that detects carbon monoxide leaks from multiple sources such as faulty fuel-burning appliances and blocked chimneys. If a threat is detected, the alarm emits a spread spectrum horn tone that is designed to be heard by people with age-related hearing loss. Made to be hardwired directly into the electrical system of your home or facility, this 120-volt hardwired smoke detector features a backup battery that helps keep the alarm functioning even in the event of a power outage. The alarm's perfect mount system allows for easy installation and alignment, while its low battery latch gives a visual indication if the battery is running low.

User questions & answers

Question:	How often do these need to be replaced because of "end of life" warning? I feel like we are constantly replacing them and don't know what's normal
Answer:	The installation instructions for this unit notes that it can be wall mounted, "If allowed by local building codes," (check with your Buildings Department - since several codes are in use in various localities) - with the proviso that the top of the mounted unit must be between "4 inches and 8 inches" below the wall-ceiling meeting, to avoid dead air space.
Question:	Will this First Alert unit plug into my existing BRK 3-wire pigtail connector, or do I have to buy a BRK unit? Thank you
Answer:	Off-white.
Question:	Does anyone know if this smoke/carbon monoxide alarm is compatible with a house full of First Alert 9120Bs (smoke only)? Want them all connected
Answer:	Nor sure about that particular standard, but box states that it complies with ANSI/UL Standards, California state fire marshal, FHA, HUD, and National Fire Protection Association.
Question:	I have Model No. SC7010BV. Is the same replacement without the "V
Answer:	The beep is effective. It always seems to start in the middle of the night. I twist the unit off the ceiling and do a battery swap and have it back on the ceiling in less than a minute, craw back into bed before really waking up. It's not a pain to replace the batteries, it's very easy. Simply slide the tray out and pop new ones in. The batteries fit snuggly in the compartment and there are tabs that allow you to push the batteries out by applying pressure with your thumbs from the back side. There is an optional screw hole to make the battery compartment tamper resistant. This prevents people from easily taking the batteries to power their remote controls or whatever. When fire marshals inspect fire related deaths it's not uncommon to find the smoke and fire detectors had no batteries installed. This simple, optional, screw might seem like "a pain" to some people, but it's an easy way to save your life. This is a great unit. I have 6 in my house and I highly recommend them to everyone.

Question:	Will this pick up my dog at night

The trick is can your received decode the digital signals and that depends on your receiver or scanner capability. My SDS-200 is a software controller scanner and with the addon module it can follow digital trucked signals or other digital transmissions. Most public services are switching to digital since patrol cars have laptops and then piggy back their send/receive on the digital radio frequency so both voice and data can be sent over the same band.

Product description

The Kidde KN-COEG-3 AC powered, plug-in CO and explosive gas alarm protect you and your family from two deadly threats. The KN-COEG-3 includes 9V battery backup that provides protection during a power outage, when AC-only units cannot provide protection. By pressing the Peak Level Button you can see the peak CO level recorded by the alarm since it was last reset or unplugged. The continuous digital display shows you the level of carbon monoxide (if any) the unit is sensing as well as if gas is present. The gas sensor is a metal oxide sensor designed to detect natural gas (methane) or propane. Temperature range- 40 degree Fahrenheit to 100 degree Fahrenheit.

Protect your family from the dangers of carbon monoxide (CO), methane, and propane exposure with the Kidde KN-COEG-3 Nighthawk Plug-In Carbon Monoxide and Explosive Gas Alarm. The Nighthawk is an easy-to-install unit that provides reliable protection against the dangers of CO and explosive gas. The digital display shows if gas is present indicates CO levels in parts per million, allowing you to see if, how, and when levels change.

Advanced Technology in an Easy-to-Install, Plug-In Design

Designed for home use, the Kidde KN-COEG-3 Nighthawk is a UL-listed, A/C-powered, plug-in alarm that utilizes sophisticated electronic components and sensor technology to protect you and your family from the dangers of CO, methane, and propane exposure. It plugs directly into a standard A/C outlet and includes a 9-volt battery backup that provides continuous monitoring--even during power outages.

The Dangers of Carbon Monoxide, Methane, and Propane Exposure

The leading cause of accidental poisoning deaths in North America, carbon monoxide (CO) is often referred to as the silent killer because it's odorless, tasteless, and invisible. Carbon monoxide poisoning can come about via a number of sources, including everyday items and appliances in your home or office. And because symptoms of CO poisoning mimic the flu or other common illnesses it can often go undiagnosed.

Likewise, methane and propane gases are commonly used in homes for cooking, heating, and water heating. Although it happens rarely, gas leaks can sometimes occur inside the home, increasing the risk of fire or explosion.

Audible Alarm Pattern Alerts you to Elevated CO and Gas Levels

When placed on every level of your home, alarms like the KN-COEG-3 Nighthawk can help protect everyone in the house by giving you an unmistakable signal when gas levels have reached an unhealthy point. If unhealthy levels of CO are detected, the alarm will emit four quick audible beeps every five seconds until either levels decrease or the reset button is pressed. If methane gas or propane gas is detected, the alarm will emit beeps every other second with "GAS" shown in the display.

Easy-to-Read Digital Display Shows CO Levels

The KN-COEG-3 Nighthawk is preferred among traditional CO and explosive gas alarms because of its digital display. This display clearly shows levels of CO that the unit has detected and stored-- from 30 to 999 ppm--and it updates every 15 seconds to indicate any abrupt changes or alarming trends. The display also shows the peak CO level recorded by the alarm since it was last reset or unplugged. The continuous display also shows if gas is present.

LED Shows Sensor Status

With the KN-COEG-3 Nighthawk, you never have to wonder if the sensor is functioning properly. A blinking dot in the lower right-hand corner of the display denotes normal operation, so you can trust that it's working. In addition, you can test alarm function by pressing the test/reset button at any time to verify that the horn and electric circuitry are operating properly.

Convenient Mounting Options

The KN-COEG-3 Nighthawk has a low-profile design that makes it suitable for any room in your home. The detector can be plugged into any standard A/C outlet; it's plug can be snapped into the back of the unit and can be rotated so the alarm remains vertical, independent of whether the electrical socket is mounted vertically or horizontally. In addition, the alarm comes with a 6-foot extension cord, so the unit can be plugged into the wall outlet and then placed on a table or shelf. For the most thorough protection, place an alarm on every level of your home.

The UL-listed Kidde KN-COEG-3 Nighthawk has a seven-year life and is backed by a five-year limited warranty.

User questions & answers

Question:	What is the sound level I need one for basement and need to hear on ground floor
Answer:	Dear cutomer, excuse that this prodcut Y301 can't detect hydrogen gas, it's mainly sensitive for methane and propane. thank you very much
Question:	is this an explosive gas and carbon monoxide detector? it only says "carbon monoxide detector" on the actual product
Answer:	Don't worry, it's normal, the large moisture change can affect the sensor performance, and may lead to false alarm, but the data on display only switch to 1,2 or 3, but won;t trigger the voice and light alarm. If the data become 5 or more than 5, voice and light alarm will be triggered. Thank you very much and best regards.
Question:	No manual included. Do I just plug it in and test it? What does it display if gas is detected? Thanks fellow Amazoners
Answer:	HI Niran, it's sensitive to methane and propane. We think it can't used to monitor and detect CO. thank you vey much
Question:	I smell natural gas in my house, and am wondering if that is the same as explosive gas? Will it detect natural gas
Answer:	Dear Karen, temporarily the Y301 doesn't get UL certification, it passed CE, FCC, EMC and RoHs. We are applying US ETL certification which is equivalent to UL certification. Thank you very much and best regards.

User questions & answers

Question:	I see there are air holes in the back, so if it is placed against a surface, won't it impede the airflow into the detector
Answer:	According to the company's website, the unit should be placed on its back (display facing upwards), on a flat surface, at breathing-level height, and away from windows, doors, air vents, etc. See https://support.airthings.com/hc/en-us/articles/115003370189-How-do-I-place-my-Home-radon-detector-to-obtain-correct-measurements- Or as their FAQ answer states: "You can just lay it flat on a table or a shelf. The air flows into the Radon chamber as usual." https://support.airthings.com/hc/en-us/articles/115001097069-Can-I-just-lay-the-unit-flat-on-its-back-side-
Question:	what is the shortest amount of time you can do a test with this device? a home inspection last only a few hours..will it have to be left over night
Answer:	Professional testers need to be used for a 48 hour test. For this home unit, it should run at least a week to be somewhat accurate. A month would be better. It will have a 20% deviation for a 48 hour test. 7 day test should be around 10% deviation and 2 months around 5%. Right now, mine has about a 30% deviation compared against professional 48 hour testers. I'm contacting support now for help. I've owned it for about 6 months.
Question:	Are we positive the readings are accurate? I have now tested the first floor of the house and am getting a reading of 7.5 pCi/l
Answer:	We have two older (15+ years) Safety Siren meters that read 2.3 & 2.4 for both long and short readings and seem stuck even after a reset/retest in our radon mitigated basement. The new Airthings 223 started a little over 2.0 and slowly dropped to 1.8. Yesterday I resealed the sump pit covers to the floor and the Airthings 223 1-day average already (
Question:	how often does the tester need to be calibrated and how much does it cost to calibrate
Answer:	My answer has nothing to do with radon concentration in the tested environment, but incorrect terminology being used on this discussion thread. Resetting the radon sensing instrumentation means system initialization to factory calibration, as the unit is not user calibrate able. Calibration implied by this question is to a standard, and it must have been done with the prototype designs when tested against known radon concentrations in chambers...using perhaps master instrumentation. I think this device can give you values within some level of confidence like 95%...but the measure value of any unit like this is not to be taken with 100% confidence.

Long and short term trends help you stay on top of radon levels.

Monitor your air quality.

Radon gas is in the air all around us and levels fluctuate daily. The good news is that a digital radon detector warns you when levels are getting high. Simple fixes around the home can dramatically improve your air such as increasing ventilation or sealing cracks in floors or even installing radon mitigation systems and radon fans.

Continuous, long-term monitoring

21,000 deaths are attributed annually to radon gas in the US alone. This and other radon side effects can be prevented by monitoring.

Remember to monitor for radon daily so that you can make small adjustments to improve the quality of your air.

Odorless, colorless, tasteless

Radon is a naturally occurring, radioactive gas that comes up from the ground and can accumulate to unsafe levels in the home. It is odorless, colorless and tasteless.
