Smoke/Heat/Co2 Alarm Recommendations

padstar · 17 Jul 2022

Got everything wired over the weekend. All heads wired and linked. Will be using the combine co heads rather than stand alone ones for the extra cost I thought sticking with the same brand heads everywhere was best especially.

Got the identifier switch installed as suggested so hopefully it gives a decent robust system that will last for several years.

What would be nice would be if Aico did a combo that combined both sensors (heat & smoke IIRC) of the 3028 with CO. I'm fitting a separate CO head so as not to lose either of the smoke detectors of the multi-sensor head.

You can't mix and match different manufacturers in a linked system. At best it's not supported, it probably won't work, and there's a real chance of damaging the detectors which is a quick way of negating any savings.

AICO...... end of discussion

Thanks for all the recommendations. Glad I went with Aico. Have only heard good things about them. Also the test switch is a great idea. All fired up last weekend and working fine.

Do you need CO in the kitchen if there is a Ha supply in there?

Ha supply ?
If there's a fuel combusting appliance other than an oven or hob then it's needed (legal requirement). But I'd fit one anyway even if there's only a hob - as is the case in one of our properties.

Sorry gas supply not Ha.

I have a gas supply into the kitchen but capped off not being used currently as everything is electric.

Do Co sensors detect gas leak? If not then is there any point in having the co sensor in there

SimonH2 · 12 Nov 2022

If no gas appliance (and I assume, no solid fuel or oil) then no need for a CO detector. CO detectors only detect CO from incomplete combustion of hydrocarbon fuels, they don't detect gas leaks.
A periodic inspect & test of the gas installation and any appliances (mandatory each year for rented properties) will detect any leaks and unless fiddled with, new leaks should not occur. If one did, the stench agent added should alert your nose long before it becomes flammable - I believe it's detectable when the gas is still at only about 1/4 of it's lower combustion limit, but I wouldn't want to depend on that as a safety mechanism
