12 best tools more carbon monoxide detectors

Product description

The Kidde i12010SCO is a hardwired combination smoke and carbon monoxide alarm that contains a 10-year, sealed battery backup. This alarm uses breakthrough technology to offer a fast response to real fires, including smoldering and fast-flaming, as well as protect you from carbon monoxide and dramatically reduce the chance of nuisance alarms. The Intelligent sensor technology combines the detection capabilities of an ionization smoke sensor – which is more likely to detect smaller, less visible fire particles, like those produced by flaming fires – with that of an electrochemical sensor, which is used to detect CO. Since carbon monoxide is present in all fires, having both detection chambers work together in one alarm is a breakthrough in the fire safety industry. When either sensor notices a potential hazard, it will communicate with the other. Depending on what is detected, the alarm will adjust its smoke sensitivity in order to better discriminate between a real hazard and a false one. This constant communication enhances the alarm’s overall performance in all fires, and significantly reduces the potential for a nuisance alarm. Peak Level Memory-Announces “CARBON MONOXIDE PREVIOUSLY DETECTED” if alarm has detected CO level of 100ppm or higher since it was last reset. Humidity Range - 10%-85% non-condensing relative humidity (RH).

• Provides protection from two hazards - Fire and CO in one unit with 10-year sealed lithium battery backup.
• Sealed-in lithium battery backup - No battery replacement required over the 10 year life of the alarm. Eliminates worry about removal or unauthorized deactivation of alarm.
• Voice warning system - Verbally announces “Fire” or “Warning, Carbon monoxide” to help distinguish between threats. Audio alarm: 85 dB at 10 feet
• Ionization sensing technology - Ideal for detecting fast flaming and other types of fires. Temperature Range: 40 degree F (4.4 degree C) to 100 degree F (37.8 degree C)
• Hush feature - Temporarily silences nuisance alarms for approximately 9 minutes and will not allow hush mode unless the unit is in alarm mode. Interconnects - Up to 24 Kidde devices (of which 18 can be initiating).Flashes once every 60 seconds to indicate battery only mode
• Compatible with Kidde, FireX, code one and sentinel products

Product description

Kidde Monoxide Alarm.

From the Manufacturer

The leading cause of accidental poisoning deaths in North America, Carbon Monoxide is odorless, tasteless and invisible. It is a silent killer. Kidde CO alarms include the most accurate sensing technology available, the patented Nighthawk electrochemical sensor. This unit combines a Carbon Monoxide and Ionization Smoke Alarm, providing two important safety devices in a single unit. This alarm includes a voice warning system that announces "Fire, Carbon Monoxide, Low Battery or Smart Hush Activation." The voice alarm eliminates any confusion and clearly warns you and your family of a smoke or carbon monoxide danger, or if your battery is in need of replacement. This unit is hardwired and will work with many interconnected systems. This combination alarm has battery backup, protecting you and your family even during a power outage when many incidences occur. Install at least one CO alarm on every floor and in sleeping areas. Make sure CO and Smoke alarms are at least 15 feet away from cooking or heating appliances to prevent false alarms. Replace CO alarms every 5 to 7 years to benefit from the latest technology upgrades. 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.

• Smart Interconnect-Interconnects up to 24 Kidde devices (of which 18 can be initiating), Battery Backup (2-AA batteries included)-Provides protection during power outages. Front Loading Battery Door-Replace the backup batteries without disconnecting from mounting bracket
• Humidity range: 10%-95% relative humidity, non-condensing. Battery Lockout System-The battery door will not close unless the batteries are properly installed, Alarm Tamper Resist-Helps deter from tampering and theft, Adjustable Mounting Bracket-Makes installation fast and easy. Works with existing smoke and combination smoke and CO mounting brackets.
• Peak Level Memory-Announces “CARBON MONOXIDE PREVIOUSLY DETECTED” if alarm has detected a CO level of 100ppm or higher since it was last reset, HushTM Feature-Silences nuisance alarms for approximately 9 minutes. (Smoke must be present before HushTM is activated)
• Ionization Sensor Technology-Ideal for detecting fast flaming and other types of fires, est Button Functions: – Tests the unit for proper operation - Peak Level memory - Resets the Carbon Monoxide alarm
• Green LED-Illuminates to indicate the unit is receiving AC power. Flashes once every 60 seconds to indicate battery only mode. Flashes once per second during alarm to indicate initiating alarm. Flashes once every 16 seconds to indicate smoke or CO previously detected. Flashes every 2 seconds while the alarm is in HUSHTM mode
• Red LED-When a dangerous level of smoke or carbon monoxide is detected the red LED will flash. If the unit malfunctions, the red LED will flash and the unit will chirp every 30 seconds
• Talking alarm announces the hazard type detected, helping to speed up reaction time

Product description

Featuring a low profile, contemporary design, the First Alert PRC710 Slim Photoelectric Smoke and Carbon Monoxide Alarm with 10 Year Battery provides the same protection as a standard smoke alarm while taking up only a fraction of the space. This slim, battery operated smoke detector requires no hardwiring for installation, making it an ideal solution for those who want to enhance fire safety without hiring an electrician. It features a built in 10 year lithium ion battery that provides continuous power for up to a decade. Equipped with an ultra reliable photoelectric sensor, the smoke alarm detects smoke from slow burning, smoldering fires while keeping false alarms to a minimum. A patented smoke entry system further enhances the detector's reliability by providing a direct path to the smoke sensor. 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. The simple twist lock mounting system installs easily onto a wall or ceiling, while the tamper resistant locks help prevent removal of the battery to keep the alarm secure. Half as thick as a standard alarm, the smoke detector has a sleek, slim design that blends in seamlessly with most decor. A loud 85 decibel alarm sounds when smoke is detected, and a convenient test/silence button lets you easily check alarm function and mute false alarms. TROUBLESHOOTING STEPS: Activating the battery. Mount alarm to mounting bracket to activate. Once unit is activated, it cannot be turned off. NOTE: After you activate the battery, the power indicator light may flash. (If the unit alarms, the light will blink rapidly, and the horn will repeatedly sound 3 beeps, pause, 3 beeps.) Once the Smoke Alarm is on the bracket, you can rotate the Alarm to adjust the alignment. Clean the Smoke/CO Alarm at least once a month; gently vacuum the outside of the Smoke/CO Alarm using your household vacuum’s soft brush attachment. A can of clean compressed air may also be used. Follow manufacturer instructions for use. Test the Smoke/CO Alarm. Never use water, cleaners or solvents since they may damage the unit. If the Smoke/CO Alarm becomes contaminated by excessive dirt, dust and/or grime, and cannot be cleaned to avoid unwanted alarms, replace the unit immediately. DO NOT LOCATE THIS SMOKE/CO ALARM: In garages, furnace rooms, crawl spaces and unfinished attics. Avoid extremely dusty, dirty or greasy areas. Where combustion particles are produced. Combustion particles form when something burns. Areas to avoid include poorly ventilated kitchens, garages, and furnace rooms. Keep units at least 20 feet (6 meters) from the sources of combustion particles (stove, furnace, water heater, space heater) if possible. In areas where a 20-foot (6 meter) distance is not possible – in modular, mobile, or smaller homes, for example – it is recommended the Smoke Alarm be placed as fa from these fuel-burning sources as possible. The placement recommendations are intended to keep these Alarms at a reasonable distance from a fuel-burning source, and thus reduce “unwanted” alarms. Unwanted alarms can occur if a Smoke Alarm is placed directly next to a fuel-burning source. Ventilate these areas as much as possible. Within 5 feet (1.5 meters) of any cooking appliance. In air streams near kitchens. Air currents can draw cooking smoke into the smoke sensor and cause unwanted alarms. In extremely humid areas. This Alarm should be at least 10 feet (3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher, laundry room, utility room, or other source of high humidity. In direct sunlight. In turbulent air, like near ceiling fans or open windows. Blowing air may prevent CO or smoke from reaching the sensors. In areas where temperature is colder than 40˚ F (4.4˚ C) or hotter than 100˚F (37.8˚ C). These areas include non-airconditioned crawl spaces, unfinished attics, uninsulated or poorly insulated ceilings, porches, and garages. In insect infested areas. Insects can clog the openings to the sensing chamber. Less than 12 inches (305 mm) away from fluorescent lights. Electrical “noise” can interfere with the sensor. In “dead air” spaces. See “Avoiding Dead Air Spaces”.

User questions & answers

Question:	This gets such terrible reviews...What are better choices for a 10-year smoke/carbon detector
Answer:	I have no idea if any of the brands available are any better than this.
Question:	how to silence
Answer:	There is a reset/silence button on the front cover of the detector. Push it and it should reset. If not you battery is no good and you need anew detector!
Question:	Do you ceiling mount this fore/co2 alarm? doesn't co2 settle to the ground first
Answer:	This is a CO alarm, not a CO2 alarm. CO2 is what makes your soda fizzy and is in in chained cylinders at restaurants... CO is an odorless, tasteless, colorless gas. The ONLY way to detect it is by detector. It is generated by any gas-powered appliances like dryers, stoves, snowblowers, cars, etc, and by burning like fire places. CO is BARELY lighter than air (about .96 to air being 1 for vapor density), and will mix and collect like normal air does, with drafts and normal air movement. CO detectors can be mounted at just about any height, though many manufacturers (somewhat arbitrarily) picked 5ft or chest height as the ideal mounting height. Smoke and heat rise, so smoke/heat detectors are required to be mounted within 12" of the ceiling. Combination detectors are common, and need to be mounted within 12" of the ceiling for the smoke function to operate properly.
Question:	Does it use the same ceiling mounts as previous first alert detectors
Answer:	The ceiling mount is different, but the screws are in the same place. Just loosen the screws, swith mounts, and tighten back up.

User questions & answers

Question:	If there is a false alarm, can I turn this off from my i-phone
Answer:	I open back back forgot I had installed alarm, I have a keypad by back door. When alarm sounded true keypad, nothing. I ran to unplug. Duh, battery operated then run to phone. Phone stopped everything. I didn't even get a call. That happened December 30 2018.
Question:	How long does the battery last
Answer:	At first my batteries were reporting 85% after 6 months, and again about 85% after the second 6 months. Then I helped my neighbor in the condo next to me setup a zwave system. Suddenly my batteries are only lasting 4-6 weeks. In other words, your signal strength will have a lot to do with how long the batteries last.
Question:	Will this, if wired to an existing system, trigger a notification if a non-z-wave Alarm goes off (can I buy just one or do I need to replace all
Answer:	I don't think this can be wired to an existing system? It doesn't have the receptacles on the back like the wired units do. So, as far as I can tell, you'd have to replace them all. As an aside, I left my wired system in place (4 detectors) and just installed 2 of these. I figured if we're home the wired system will alert us inside the house. If we aren't home the zwave alarms will trigger eventually, but potentially not as quick (depending on source of smoke) without the same number of detectors.
Question:	are they hard wire? (120v with battery backup) and do they have an interconnect wire
Answer:	No, thus they are not code compliant in most jurisdictions since interconnect is often required.

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.

User questions & answers

Question:	Does this product have to be mounted
Answer:	The turrets on the E1 will not feature a true "zero stop". They have a resettable numbered collar that you can align with zero when you are done making adjustments.
Question:	Can anyone tell me how far apart the screw holes are in the back? Trying to find one that matches what I have
Answer:	No bikini cover, no caps.
Question:	What is the detector life time? Is it 10 years? When was this batter made
Answer:	Yes this will fit with a low height rings on a Remington 700! I have one mounted on a Remington 700 bdl
Question:	of 5 product photos on this listing are of a mini-fridge, not a CO deterctor? Does not give me much confidence in seller if listing is not correct
Answer:	Me owning both a 44mm and a 50mm I’d say if you want one for lower light go 50mm. I’ve heard that it doesn’t matter but like I said i have both.. the 50mm you can see earlier in the morning and later into the night.. only down side is if your facing a sun rise or a sun down the 50mm absorbs to much light causing a glare.. you can buy a screw in extender that takes care of that tho.. hope That helped
Question:	How often does it need calibration and what is the cost? Thanks you
Answer:	This is an amazing scope. Like the others have said handling a 416 rigby and a 338 win mag itll hold up to the 7.62x39 for sure. I know ur thinking probably about the continual jarring of a semi automatic but this scope holds up just fine. Best thing is u cant go wrong with vortexes warranty. I have two a 2-7x32 on my 375 HH, and a 3-9x40 on my .30.06, and only had one issue on the 3-9x40 from a shooting trip after i got it home i guess it got knocked around too hard and there was like dirt inside of the glass. I called vortex they sent me a sgipping label and said well fix it ir replace it and in a week or two i got my scope back good as new. I love vortex the scopes are great, and the customer service cant be beat.
Question:	What is the accuracy
Answer:	The scope does not come with flip up scope covers. I purchased Butler Creek ones and they work great. For the eye piece go with size 14-15-16 (their sizing is weird) and for the objective go with 13-15. They work great and I have no complaints.
Question:	Can this test flue stack co
Answer:	FriendThe scope attaches to ar15 and any other W/ 22mm Rail Mount Picatinny Rail.Usually it will fit your gun, if your AR-15 556 has an elevated front sight you may need to purchase a piccany riser to elevate the scope or remove the front sight. I hope this answers will help you.
Question:	What is the life of the sensor
Answer:	Buy an elevator rail and you can see sights need 1.5 inch. Measure first I got 1" not enogh. Scope is awesome.

Product description

This 6 pack of First Alert hardwired smoke alarms includes a 9 volt battery backup that continues to protect you in the event of a power failure. The detector features an ionization sensor for detection of smoke and fast flaming fires, as well as a loud, 85 decibel alarm. One button silences any nuisance alarms, and also tests detector functions, while lights indicate if the alarm detects smoke. The latching alarm indicator automatically identifies which unit initiated the alarm, even after the conditions that set off the alarm have subsided. And an end of life signal enhances your safety by letting you know when it's time to replace the unit. Connect it to compatible BRK or First Alert alarms within a single family residence. When one alarm is triggered, all connected alarms will sound.

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:	Hello. No. Our current alarms do not work with First Alert alarms and they are not compatible. They will either need to be all Kidde or all First Alert.
Question:	can these be connected together so if one is set off they all go off
Answer:	Yes
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:	Up to 12 smoke or smoke + CO alarms can be connected, along with up to 6 non-alarm devices, such as strobes and horns. This is per the manufacturer's website.
Question:	Can a BRK Model 92120B smoke detector directly plug in and replace an old BRK Model 4120B smoke detector (without an adapter
Answer:	Hello. While the alarms are going off, the alarm setting off all of the others, the red LED light and then the green LED light will blink, every second. The other alarms will just have the red. If they stop on their own, the alarm that set off all of the others will have a red and amber LED light flashing one second each every 10 seconds. If you are getting nuisance alarms, we would recommend going ahead and blowing out all of the alarms around the back side edges very thoroughly with a can of compressed air like a can of keyboard cleaner. This will go a long way to avoiding nuisance alarms. Feel free to call us at 1-800-880-6788 with the problem alarm in hand if this doesn't help.
