Mains powered combined CO and smoke detector

[Hibbo]

Do they exist? I'm sure I saw one online sometime last year, but I can't find one now. I've seen battery powered combined units, but not mains.

Anyone know of such a thing?

Cheers.

YOu can get them but, i cannot remember who stocks them, try SDfirealarms

Or just start with the websites of the likely suspects, Kidde, Aico......?

Hibbo - you should also consider the following:

1) Is the location that's best for a CO detector also the best for a fire one, and vice-versa?

2) Is the type of fire detector in the combined one (heat/photo-electric/ionisation) the best sort for the location where the potentially CO producing item is?

3) If there's a hush facility, does it leave the CO part working?

4) Does the alarm give off two distinct alarm tones so that you can react appropriately for whichever event triggers it?

5) If it has an interlinking capability will either event cause it to trigger the other alarms?

Thanks for the pointers ban,

If I can find such a unit, I will place it in the hallway of my flat, where it will be with 1.5 metre of the kitchen, both bedrooms and living room doors (it's an L shaped hallway). The only (potential, hopefully!) sources of CO will be the combi boiler and gas cooker, both in the kitchen. I think this position is ideal for a smoke alarm too - central in the flat and close to all habitable rooms.

Most of the battery powered combined detectors have two distinct tones for smoke and CO, so I'd hope that a mains one would be the same.

I'd not considered the hush situation - I'll check that (if I find one). How long is the 'hush' normally active for, until the smoke clears (literally!) or is it timed?

I'm not planning on interlinking, as I think one unit will be enough for my small property.

Hmmm, found this one here http://3in1combinedalarm.yolasite.com/, but it needs an AC adapter, so is not quite the 'mains powered' I was looking for. It also come with a wall-wart type transformer, so not really ideal for mounting on a ceiling.

Also that "review" was written by the guy who sells them...

Maybe some other people here can recommend other known and reputable brands.

"Detection Gas: LPG, LNG, CO & Smoke"

Hmmm, now unless my chemistry escapes me, smoke rises.

CO, like CO2 sinks, LPG definatly heavier than air, sinks, guessing LNG is liquified natural gas, not sure on the one, but think it sinks.

so how is a combined detector going to be of use seeing as you can't ever put it in the ideal location for detecting all the gases??

just my 2p

CO, like CO2 sinks

No - at room temperature CO is lighter than air. Not by much, I grant you, but it is lighter.

I stand corrected on CO then...
