User questions & answers

Question:	When I unplug this device the green light goes off even though the batteries are installed as a backup. Is that normal
Answer:	It's about 5 1/2 in from hinge to hinge ~ 14.5 cm. It does provide full cover. The foam is flush with my face without being uncomfortable. It however is not waterproof. The foam has air slots so it can breathe. I've used these for Chemistry lab as well as wood working, and they work great.
Question:	When I try put battery in or plug it in, the alarm goes off! Does that alarm sound stop? It's brand new
Answer:	They stay on surprisingly well! I use them for my dog grooming business. They are light weight so that works good for me. They might be a bit too light for sports. If you got hit with a ball they would probably crack and potentially cut you.
Question:	How do you turn on the "low battery hush
Answer:	Yes, it should do a good job to keep out drywall dust. However, I ended up removing it due to condensation buildup while using it
Question:	What is the location of the wall plug on the device? Will it cover the entire outlet
Answer:	yes they can fit over Rx glasses but I don't recommend because they became blurring and you will not see very well

User questions & answers

Question:	Would this device work in a 6' x 6' hunting blind with a Mr. Heater heating unit
Answer:	Not for sure but wife read that rhey can fluxiate between 0-3 with no problems mine does it also
Question:	your cob b lcm coc allarm is 15$ 6 is 99$ . why does quantity coct more
Answer:	When I used the digital gas detector to test it worked fine.
Question:	How far apart are the mounting holes
Answer:	There are two possible causes. The unit was not zeroed out upon activation or you do have a very low level of gas in your home atmosphere, with the first being my best guess. Unplug and move and re-check the reading. If this does not resolve the issue send it back for a new one. Mine has worked well for 6 months so far.
Question:	Why is the 2 pack more than 2 times the price of the single detector
Answer:	I returned these detectors. They don't have any information printed on the case - no manufacturer name, no instructions, no UL approved indicator, etc. These were made in China which is usually okay but I am not comfortable in relying on them to protect my family. I will be researching further and looking for better detectors that can be trusted.

About Carbon Monoxide: The Silent Killer

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.

Audible Alarm Pattern Alerts you to Elevated CO Levels

When placed on every level of your home, alarms like the KN-COPP-3 Nighthawk can help protect everyone in the house from CO exposure by giving you an unmistakable signal when levels have reached an unhealthy point. If unhealthy levels are detected, the alarm will emit four quick audible beats every five seconds until either levels decrease or the reset button is pressed.

Easy-to-Read Digital Display Shows CO Levels

The KN-COPP-3 Nighthawk is unique among traditional CO 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.

LED Shows Sensor Status

With the KN-COPP-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-COPP-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-COPP-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.

Answer:	Is this your question: How can I tell of my water heater and furnace are emitting CO (carbon monoxide, a dangerous byproduct of combustion) improperly? If so, here are two replies: 1) this device can detect if CO is present in lethal amounts in a *closed* space and 2) the only way you can determine if a water heater or furnace is vented properly such that no CO is released into the area in which they are located is by through physical inspection by a licensed individual. (Gas pipes also must be inspected.) CAUTION: This device would be of no value in a garage as a garage is not a "closed space." (These detectors are installed in *living* areas.) Furnaces and water heaters should be inspected at least yearly for broken elements and leaking vents and flues.

Features

The KN-COB-IC is an essential device to help warn you and your family of dangerous carbon monoxide levels in your home. This alarm measures the exposure to carbon monoxide over time; it is designed to sound at 85 decibels at 10 feet when it detects 70 ppm (parts per million) of CO for 60 to 240 minutes, 150 ppm for 10 to 50 minutes, or 400 ppm for 4 to 15 minutes. The added benefit of being able to interconnect this unit with up to 23 other Kidde devices—such as other CO alarms, smoke detectors, and heat sensors—all on one wiring network delivers extensive protection against fire and carbon monoxide (as well as peace of mind). The 9-volt battery backup provides continuous security if the power goes out. An LED lighting system on the unit signals power levels and sourcing: The green LED is steadily on when AC power is present and will flash every 7 seconds when in battery-only mode; the red LED will flash in unison with the sounder pattern for both a smoke or CO incident, and it will flash once per 30 seconds if the alarm needs service or be steadily on if the alarm is in error mode; and the amber LED will illuminate if the unit is the originating alarm in a CO incident. This device has an expected 7-year lifespan and comes equipped with a 5-year manufacturer’s limited warranty.

User questions & answers

Question:	Can you run this on battery only
Answer:	Yes almost certain it’s same 3 wire plug on back of kidde detectors. (Worst case they can be spliced. have to splice anyway to any detector)
Question:	How long will it run on battery if the power is out
Answer:	There is a 5 year warranty on this device. Usually the fire department says to change out your smoke alarm every 7 years, and change the battery every year. They recommend marking your calendar, for the same time every year, so to be sure you have a good working device in case of a power outage and can still hear the audio alarm.
Question:	What is the difference between this kidde model kidde kn-coeg-3 and the kn-coeg-3 nighthawk besides price
Answer:	i would believe if your system is a 120 volt hard wired system with three wire connection s, this will operate. The red wire connects to send alarm signal to additional detectors and all should sound.
Question:	Where is best place in home to install
Answer:	It can be interconnect with compatible smoke detectors but does not work as I expected. The smoke alarm alert sounds on the CO alarm but the CO alarm alert does NOT sound on the smoke detectors. To me this is not interconnect.
