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.

FIND GAS LEAKS AT HOME:

Find the location of any natural gas, propane, LP or fuel leaks by running sensor probe along a gas pipe, fuel line, or fittings near any gas smells. Pinpoint fuel leaks from your lawnmower or car. Gas leak is found when alarm sounds and LEDs light up. Don't pay a technician's $100+ diagnostic fee when you can find a gas leak anytime with this propane & natural gas detector.



STEPS/TIPS ON USE: (see video at https://www.amazon.com/vdp/17873f5854174d4db2087794a60238be)

-To detect leaks while minimizing false alarms, turn the sensitivity dial upward toward (+) until the device begins to alarm away from any gas leak. Turn sensitivity dial downward (-) slightly until alarm stops and 1st LED just turns off. Now, any small increase of gas level (as from a leak!) will cause the alarm to sound.

-If alarm sounds prematurely, sensitivity needs to be decreased to prevent false alarms.

-Each leak varies in leak rate and background gas concentration, so adjust sensitivity level to find any leak.

-Allow device to warm up sensor for 10s until yellow “Warm Up” light turns off.

User questions & answers

Question:	is it precise
Answer:	Yes ours came with the headgear
Question:	Is any detection of gas harmful? My apartment supposedly just fixed its gas leak, but this is still showing the first level red light within my apt
Answer:	Don't know the max size. I wear a 7 3/4 hat and this fit fine. There is a minimal amount of adjustment left.
Question:	Do I need to replace the sensor after 2 years to keep this working? Or, is the unit useless after about 2 years? I read the sensor tip has a lifespan
Answer:	These type of hard hats is varies but it is fiberglass though. The color can be light to mid dark brown. They ship me with a light brown one. I was surprised it was very light, it was thin. Just be careful when buying from Warehouses. They say they will give you a new ratchet suspension but they never did. So be aware of that and if it happen they won't ship you a new one, they will ask you to reship it back and buy a new one, hopping you will receive the hard hat with the suspension but NO GUARENTEE. But to answer your question, yes it does look like that, but remember it varies on the seller because it come from a warehouse.
Question:	I don’t understand after it warms up how to detect gas ? Do I move the button until it stops ticking and no alarm? I move + and alarms sounds
Answer:	Front brim, ball cap style.

Techamor Portable Gas Leak Detector/Sniffer - Y201

The Y201 portable sniffer is an easy-to-use device that provides sound and visual alarm in presence of methane, propane, such as LPG, fuel and natural gas.

It’s mainly used to find and locate exact gas leak point along gas pipeline, around fittings or connectors at home & VR, and other similar applications. Helps to save hundreds of diagnostic fees from technician or plumber, and makes it's possible to debug gas leakage anytime by DIY.

For 24h gas monitor and detection, refer to Y301 and Y302.

2.1 Warm up process: around 10s

The speaker will always have “di didi…” until we turn off device, except one moment in step 2.2. At warm up period, ticking noise frequency is slow: around 2~3 times/s.

The knob is used to adjust sensitivity of detector after finish 10s warm up process, during the process, no matter how to adjust the knob, the device won't have any reactions.

2.2 Rotate the knob to adjust sensitivity

If the alarm sounds prematurely and LED lights are on after warm up, need to decrease sensitivity to prevent false alarm (dial downward "-", shown as red arrow) .

Rotate the knob to adjust sensitivity until the first bottom LED turn off or at the threshold of lighting up, and the moment that ticking sound stops. This is the best status.

But if it's inconvenient to get the best status, we can just make the first bottom LED be on and have slow ticking "di di...." sound. Because once encounter leakage, all the rest 4~5 LED will be triggered on together at just one moment.

2.3 Ready to sniff or trace leakage

Move the probe along pipeline or around the suspected leakage points, such as fittings, connectors and switches, once encounter gas leakage, all 5~6 LED lights will be triggered immediately and the low frequency (2~3 times/s) ticking will change into piercing sounds (frequency 6~7 times/s, too fast and human ears cannot distinguish one time by one time) .

3. Different Usage Pictures Collection from Lovely Customers

4.1 Could tell more related to use?

1) Easy to understand video will be good choice, refer to “How and where to use the Y201 gas leak detector” around pictures area at beginning . 2) Get service support, engineers on staff from factory online will help to answer any questions related to leakage if above video can't help to understand.

4.2 Why always has ticking sound?

The design of ticking sound has two purposes: 1) Indicates the device is working.For some cases, we need to extend the probe to the area that we can't see LED lights, customers could judge thru the sound changes. The green power LED light is also used to indicate the device is working. 2) Represent different levels of gas leakage. Low frequency (around 2~3 times/s) means warm-up period or no leakage, if changed into high frequency (around 6~7 times/s) during detection process, means encounter leakage issue.

Notes: above is based on we set sensitivity well, because if we rotate the knob at anti-clockside too much, even there don’t have any leakage, all the 6 LED will be triggered on and sound will become piecing high frequency.

4.3 Some batteries only use 10~15 minutes, then low battery indicator is on.

According to our experiment data at lab for different batteries brand, usually last from 15 minutes to 4 hours. Different brand batteries have very different quality. Indeed, the device is hungry for batteries. The sensor in the probe needs large power for micro burning process and we can feel a little warm if we use finger to hold the probe. Another reason maybe product itself, components (resistor, capacitor......) tolerance or damage on the PCB board may also lead to large power consumption, but the rate is very low.

Usually when we find customers from home inspection company, we will suggest purchasing rechargeable Li-batteries, because their technicians or plumbers use the device frequently and Li-batteries will help to save some batteries cost.

4.4 Is it normal or safe if get 1 red bar when move to high moisture room, around connectors or simply blow on probe?

Don't worry, it's normal, the large moisture change and CO affect the sensor performance, and may lead to false alarm by 1~2 LED red bars, but only last for 1~3s (very short time) if we move probe away. If we encounter leakage along the pipeline or connectors, all 5~6 LED bars will be triggered on at one moment, light and piercing sound alarm will last at least for 6~8s.

4.5 what's best distance between probe and pipeline/ranges/connectors.... during check process?

Recommend 1~10cm, if too far, concentration will become smaller as distance increase from leak point, and maybe not enough find and locate tiny leakage.

4.6 How about bubble method to check leakage compared with Y201?

Bubble is very good way and can be used to check all kinds of gas leakage while Y201 is mainly used for combustible gas. But for very tiny leakage and very strong leakage, bubble method maybe not good enough: 1) too tiny leak can't blow up bubble, too strong will blow the liquid away and can't have bubble, 2) some areas we can't extend to apply bubble liquid, 3) need good luck and skills to control the bubble liquid concentration if DIY bubble liquid, 4) in some case, liquid contact may lead to equipment or device damage.

The best way is: use both methods for double confirm if allowed, since bubble is more visible.

Question:	I have a 30-442 no p no -wt will this work the same or is their a compatable replacement? is this from the mfg
Answer:	For sure will be able to hear it.7 out of 10 sound level .
Question:	So i have a pre tell 2 in a 98 rv. it checks for leaks when turned on and won't allow gas to flow until the test is complete. does this model do that
Answer:	you may own Kidde 900-0076-01 KN-COPP-3 which looks similar but only detects carbon monoxide.
Question:	IS this a replacement for a Miti SA-8 propane detector
Answer:	download the manual from online http://www.manualslib.com/manual/111161/Nighthawk-Kn-Coeg-3.html
Question:	Is this ok to use in a regular kitchen (i.e. in a home not RV)? If yes, what do I need to buy to convert regular AC power to the 12V this unit uses
Answer:	As someone who went through firefighter 1 and 2 and got certified, yes. Natural gas will be detected by an "explosive gas detector." These detectors detect when natural gas or propane is approaching a percentage of the "Lower Explosive Limit", the percentage of the gas that needs to fill the airspace for combustion to occur. Since the two gases are different but are usually detected by the same sensor, they will go off for the gas that has a lower LEL for safety. If it goes off, leave your house imediately and call 911 for the fire department. Yes Natural gas has additives that make it smell like rotten eggs, but you can get used to this smell or it can be scrubbed entirely from the gas by dirt/soil. The latter is the cause of unexpected explosions in neighborhoods you may have periodically heard about in the news. Only way to know for sure is a detector.

1.3 Natural Gas (Methane) VS LPG (Propane)

Natural Gas is typically supplied through a main utility line connected to your home, which is comprised of methane gas and much lighter than air. If leakage, natural gas rises towards ceiling and accumulates in areas near ceiling, mount your detector around 30cm (12 inches) away from the ceiling and 1.5~3 meters away from gas supply to ensure the earliest opportunity to detect methane leak.

Propane is typically supplied to homes via delivery truck in liquid form and stored near the home in propane tanks, and much heavier than air and will collect at lower levels. Mount detector around 30cm (12 inches) away from the floor and 1.5~3 meters away from gas supply to ensure the earliest opportunity to detect a propane leak.

2.1 Step 1: Enter into 180s Warm-up period

• 180s for warm-up process when power on.
• During warm up process, short press TEST Button can switch language, default is English.
• Don’t apply gas to test during the warm-up process because the gas won’t be detected.

2.2 Step2: Normal working

• Periodically observe the detector to make sure the Green Power Indicator is on. Press the TEST button, the three lights flash and there’s a voice prompt.
• Test your alarm with butane from a cigarette lighter or propane source to make sure its function, recommend at least 1 time per 3 months.
• Ocassionally, the data may skip into 1, it's maybe enviroment humidity lead to the sensor tolerance. Don;t worry, it's normal and will recover to 0.
• Don't paint, don't apply abrasive solvents or other cleaners. Chemicals can permanently damage or temporarily contaminate the sensor inside.

2.3 Step 3: Alarm level ranges from 1% LEL (500ppm) to 20% LEL (10000ppm)

• Pre-Alarm set point is 5 (= 5% LEL, 2500ppm).
• The detector will give out a voice prompt and Red Alarm Indication flashes when the gas concentration is equal to or above 5.
• Visual and audible alarm will continue until ambient gas concentration falls below alarm set point (5% LEL, 2500ppm).
• When the gas concentration is more than 20 (=20% LEL, 10000ppm), the number on digital display will be changed into letter A.
• Press the TEST button can mute/silence the Alarm noise, but red Alarm light will continue flash until gas concentration drops to normal status.

2.4 Step 4: Get after service support when Yellow Fault Indicator Flash on or ERR

• If the Yellow Fault Indicator flash on or Digital Display will show ERR (abbreviation of error), which means sensor has lost efficacy and can’t finish data collection.
• Engineers on staff from factory help to answer any questions you have related to products usage of natural gas, propane, methane, and sewer etc.

User questions & answers

Question:	Will this run directly off a usb connection. For example in a vehicle usb port? Or is the charging brick connect to 120v required
Answer:	It's for combustible gases, like methane, propane, natural gas. It is not a CO2 detector.
Question:	Does the light remain on at all times
Answer:	I do believe R22 and 410a are refrigerants, thus not combustible gases. So this detector would not work for detecting a gas leak of that nature.
Question:	Se puede conectar a 220v
Answer:	No
Question:	Is this product compatible with Homekit
Answer:	you will have to call them. 1-800-553-4676. I was unable to find any info. methane, butane and propane and others* but that doesnt say H2S specifically.

User questions & answers

Question:	when were these manufactured ? how old are these ? where can you find the date of manufacture on this item
Answer:	If you go to the kidde.com website and find support for this model, select the "Documents" tab and both the information sheet and manual are available for download.
Question:	Where can i pull up a copy of the owner`s manual for kiddie model kn-coeg
Answer:	The manufacturer's technical specifications for this unit indicate that the unit is designed to detect natural gas and propane, which are the two most common type of gas used in heating and cooking in residential settings. Hydrogen gas is not a part of the specification.
Question:	Will it detect hydrogen gas (as in a battery bank charging
Answer:	Virtually all explosive gas monitors employ a heating element as part of their design. Because of this, such devices must be plugged into a household outlet. If they are unplugged or there is a power outage, the battery will typically allow the unit to run for up to a day or two (depending on the make and model), but then the battery will die. So the answer is no. This unit in particular will only last about one day on battery power, at which point the unit will stop working and the battery will have to be replaced. In addition, many devices, including this one, must have a good battery installed for backup or they will not operate. Hope this helps.
Question:	can they be run on battery only??? and not plugged in
Answer:	For a light rod the line is 2-6 pound test. For the medium rod it is 8-20 pound test line.
