Kidde Night Hawk 5DCO /0230 NHDCO Carbon Monoxide Alarm with Digital Display

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.

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.

We've recently moved into a new house which has a wood burner and a boiler of 1980's vintage . Although the boiler has been thoroughly checked and has been found to be working perfectly, there is a bit of me that is worried that things could go wrong so for the first time I have bought a CO monitor/alarm. Similarly I have read stories of leaking flues on wood burners causing deaths. The previous owners of the house had left a CO alarm behind but it bore a date in 2006 as its expiry date.This unit is simple to install & operate, and is neat & unobtrusive. I like the ability to check background CO levels. I did this religiously at first but do so less frequently now that I am more confident that we aren't being gassed. The alarm is extremely loud when tested so if the worst happens we should be alerted in time. Apparently the unit will give a warning when it gets to the end of its life after seven years so we won't make the same mistake as our predecessors. We haven't had any false alarms - the instructions contain information about where to site the alarm and, just as importantly, where not to site it. We have installed one unit in the hall between the boiler room and the room with the wood burner, and another on the landing. The one in the hall is close enough to the sources of potential CO poisoning to provide reassurance but not so close that the alarm goes off all the time.

These are an invaluable piece of kit that provides a level of detection from carbon monoxide. In the past I have viewed these products but like many others, I have found the price prohibitive. So it was good to see at long last that a safety item such as this, has arrived at what I think is a reasonable price.So what is it like? The alarm is slightly larger than some of the older wall mounted central heating controls. It has a digital display that advises you of any amount of C M that comes into contact with the alarm; therefore I would read this as a possible early warning system that tells you something may not be right in the house, but, I could be wrong. It is portable and can be moved around the house and one of the adverts I have seen, says it can be taken on holiday.The downside; the instructions I found are not the easiest I have read and at I times I found them in my opinion to be a mixture of providing basic safety information with technical information that I didn't have a clue about. Therefore, if you do not understand the instructions for where to place these items, then do what I did, get someone qualified who does, you may also find that you may well need more than one alarm.Also, Kidde claims that these alarms will only last 7 years, they do have an `end of life' warning system and you will have to replace them before that time, but, for 4.3 pence per week what do you expect.The bottom line is this; there really isn't an excuse not to have these detectors in your house, the choice is yours.
