5.0 out of 5 stars Fireangel CO-9D Carbon Monoxide Alarm 17 Dec 2011
Verified Purchase
The wife and I wanted a CO detector to replace the old one we bought 10 years ago. Out of interest, these units should be replaced every 6-7 years, some sooner. We have a portable gas fire plus a log burner. We wanted protection in case of a flue leak, or problems with the gas fire. The unit arrived, well packed, easy to use. There are no user-replaceable batteries, so the unit is designed to last the warranty without any intervention, which I think is a good idea. The first thing we did was activate it by removing the plastic pin - this is very easy, and the unit sprung into life. The large button on the front "tests" the sounder unit, and you can switch between room temperature and Carbon monoxide level. The display is large and very clear. The sounder is very loud - sufficient to wake anyone. Next, I ran a full test of the actual unit to see how quickly it would detect dangerous emissions. You can do this by pressing the large button until the spanner icon comes up, then the unit is in test mode. You do not need those canisters or real smoke; I used an incense stick, and held the unit above it. Perhaps you never realised that incense sticks give off potentially dangerous smoke, but don't worry, the quantities here are very small, less than a gas grill, so there is no need to worry! Within about 1 minute you could see the ppm reading rising in the display, and as soon as it reached the trigger level of 50, the alarm went off. In normal use the trigger level is 200 ppm, but the test threshold is deliberately lower, to make it easier to test the unit safely.

In summary, I found it to be an excellent unit, and I know some people have had issues with some CO detectors to trigger off without reason, scaring them, but there was certainly no false triggers with this unit.

4.0 out of 5 stars worth every penny 24 May 2012

I was weary of spending more on this detector than the others available, but when you work it out, over a 7yr period, it's negligible. The peace of mind knowing they are there is priceless. This is a high quality product. They are guaranteed for 7years too. Then you have to replace them as the sensor only lasts that long and the battery dies. The battery is a sealed Li-on, lasts the 7yrs, so no need to replace it. I bought two for up and downstairs. I tested them both and they do alarm @ +50ppm. I didn't get any false alarms. One of them did get a 99-error, but it went when I took it out of test-mode. They have been working fine the last few months.
They are also guaranteed for the 7 years which is a credit to FireAngel. If they don't last that long, you can send it back for a replacement.

One thing I will say, the alarm isn't as loud as I thought it would be. Maybe it's just me. I don't know whether it would wake me from a deep sleep. So I've kept one of them just outside my bedroom. The other is in the kitchen. You can wall mount them, or leave them to happily sit on any flat surface slightly tilted, which is a nice touch. Comes with wall fixtures too. The green LED blips every minute to let you know it's working away too.

It is aesthetically pleasing, and the option of temperature display is good to have, but you can't have both reading on at once, it's one or the other, which is a shame. The digital readout is very easy to read. It gives real-time reading in ppm and a 28day peak history too. I like the fact that when you press the button, you're testing the alarm at the same time. Recommend it!

5.0 out of 5 stars Peforms well and looks smart 9 Jun 2012
By Paul Madge #1 HALL OF FAME TOP 10 REVIEWER VINE VOICE
Verified Purchase
We bought this carbon monoxide (CO) alarm to replace a much more primitive version that had reached the end of its 6 year lifespan. This Fireangel unit arrived promptly and was well packaged together with very useful and clear instructions - it's well worth reading them in detail. There are no batteries to install as the unit is sealed for its seven year life - it uses a non replaceable lithium power cell. To start the detector you remove a small clip which activates it. You can easily replace the clip if you are transporting the unit, for example, to use on a camping holiday etc. avoiding accidental activation in transit. The unit can be wall mounted (a template is supplied) or use its base to stand on. The alarm is very loud indeed.

The design is modern with a large LCD screen that offers the bonus of displaying the room temperature rather than CO ppm if you prefer (this does not affect the functionality of the alarm). The display will also tell you if there has been a dangerous peak reading whilst you are out by displaying an icon. Another feature is a bar graph which, in the event of a gradual CO leak, will build up visually until the alarm sounds giving you an early warning of problems. You can also select a peak reading for carbon monoxide over the past month which is reset by testing the unit. A green LED flashes once a minute to confirm that the unit is operational.

There is a test function which allows lowers the alarm threshold so you don't risk poisoning yourself during the test cycle - you can use a cigarette or incense stick as the CO source. A monthly test is recommended in the instruction booklet.

Don't buy a cheap, unknown brand of CO alarm and all CO alarms should be certified to the European Carbon Monoxide Alarm Standard BS EN 50291:2001.
