## Description

The Kidde 0230UK is a battery-operated carbon monoxide (CO) alarm that uses the patented Nighthawk electrochemical carbon monoxide sensor to help protect you and your family from the dangers of carbon monoxide. The Kidde 0230UK is easy to install, and the digital display shows carbon monoxide levels in parts per million, updating every 15 seconds. When the Kidde 0230UK is operating, if hazardous carbon monoxide levels are not present its LED will flash green every 30 seconds. In a carbon monoxide emergency, the red LED pulses, and an 85 decibel horn sounds at specific intervals until the carbon monoxide threat is eliminated. The unit is powered by AA batteries that come included in the kit. This model also comes complete with an alarm function that informs you when the batteries are running low and need changing.The Kidde 0230UK is able to provide continuous monitoring of carbon monoxide levels, even during power outages--it runs on batteries, not a mains power supply. For peace of mind, a test/reset button allows you to test that alarm is functioning correctly, plus a peak-level memory keeps track of the maximum carbon monoxide levels detected between resets. The 0230UK is covered with a five-year manufacturer’s warranty and replacement is recommended after seven years.

Review: Excellent little alarm. Loud, clear, and offers peace of mind. - So far so good. The unit is operating and the alarm sounds very loudly. I hope I never have to use it, but it's there if the need arises. PROS: 1. There is a small display which shows how much carbon monoxide can be detected wherever the unit is placed. Mine reads '0' and this is very reassuring to see. 2. A large test button allows you to check that the unit operates a should. It emits a series of loud beeps, so even if you were asleep at the time, this unit would almost certainly wake you up. 3. Clear instructions. The instructions were very easy to follow. There are a few places where this unit should not be placed, and so having this explained clearly is very important. 4. Batteries included. The unit came with quality batteries (Duracell) which is nice. Often alarms come with an obscure brand of battery, but these are good quality. 5. The unit is wall mountable. It even comes with plugs and screws. CONS: I can't fault this alarm at all. I trust that it works well, and offers me peace of mind. Overall, I would recommend this alarm to anyone who doesn't have one. carbon monoxide can be a killer, and for the price of a takeaway meal, you should protect yourself and your family.
Review: Simple to use. Perfect! - This unit comes with batteries and full instructions. Plug in the batteries and it switches on. Press the test button and it takes a reading of the current levels. The instructions also list the levels you should be aware of and the unit will bleep in various manners to alert you to the danger of CO (Carbon monOxide). At any time you can press the button and it will display the highest reading taken. This allows you to monitor levels and take the appropriate action. The unit lifespan is over 5 years. You just need to replace the batteries. The batteries supplied are eco-friendly. Two screws and wall plugs are also supplied so that it can be mounted on a wall. Directions for selecting the best location are supplied with the instructions. I loved the price.

## Questions & Answers

**Q: At what level of CO does it give an alert and the nature of this alert**
A: Hi, alert is a red flashing LED and it emits an on/off high pitched beeping like a smoke detector. The display shows a reading between 30 and 999 indicating CO concentration in PPM (parts per million). Readings below 50 are ok but need looking into, anything between 50 and 100 should be investigated urgently and anything over 100 is potentially dangerous.  I have CO detectors in the kitchen, living room and hallway, they pretty much always read zero (meaning less than 30 PPM) despite gas hob/oven, gas c/h boiler and two log burners.  The only thing that raises the reading is the gas lights which are just inherently dangerous so we use them sparingly.  According the the instructions, the alarm won't sound below 50 PPM; at 50 PPM it will sound within 60-90 minutes; at 100 PPM it will sound within 10-40 minutes; at 300 PPM it will sound within 3 minutes.  Accuracy is +/-30% - readings are affected by temperature/humidity/air pressure. Hope this helps, dave.

**Q: can this product be usedwith a log fire**
A: Yes, this is why I brought one. I also have a fire alarm to.I'm assuming when you say log fire you mean log burner. Normal fires wouldn't give off co2 fumes (although don't quote me on that), but we never had a co2 with open fires as the fumes can escape.Log burners that burn wood or multifuel stoves have the capability to give off co2 when the are shut down (although you should never completely shut them down).It's a good product, I'd buy again.

**Q: will this operate on rechargeable batteries**
A: A new non-rechargeable alkali battery is about 1.6 volts.  3 of these in series give nearly 5 volts operating voltage when new.
Re-chargeable batteries are only about 1.2 volts fully charged, so 3 of these would only give about 3.6 volts.
As this device is design to work with a 4-5 volt supply, re-chargeables would not be suitable. ( unless you could squeeze 4 in !!!)

**Q: Why does the Peak Level button only display number (eg 12) after numerous successive button pushes, only displaying 0. first few times it's pushed?**
A: When you press the peak level display it shows the last reading of carbon monoxide (between 11-999ppm), so in your instance it has detected 12ppm of carbon monoxide on the last reading. The peak level memory is cleared to zero, if, whilst holding the peak level button, the test
reset button is pressed and released before releasing the peak level button.

### ⭐⭐⭐⭐ Nice looking, as they go...
*by T***E on 2 December 2012*

I didn't feel I could give an alarm 5 stars simply because it's an alarm. No other reason. So, what does it do? Well, if you press the 'test' button it makes a hell of a noise. Apart from that it just sits there and a green light flashes every now and again. Ours has '0' in the LCD window, which I believe is a good thing. It looks good and feels weighty and robust. It's a neat, small unit. However I don't believe that any of these have any bearing on it's functionality. I hope I never hear it when I shouldn't, in which case it's done it's job. Or rather, it hasn't. If you see what I mean. However, if at some time in the future it saves my life I will consider it an absolute bargain. I have smoke alarms too, which do a similar thing, but they're different. So you need both. Buy them. They could save your life and the lives of those closest to you, saving your family the hell that follows needless tragedy.
