smoke - heat - carbon alarms

[tazz]

Always been that standard on part 6...you can argue, there would be led drivers, led lamps etc, on the lighting circuit, as well as tv`s, computers etc on the ring main circuit. Down to you to check before conducting test.

Either way you just unclip the smokes etc from their bases before testing, it's not like you can't easily see where they are is it. They don't get buried behind ridiculous furniture like sockets and sw/fuses do

yep ...good point

I'm sure I read on the aico mi that co2 detectors can only be interlinked with smokes if a locator switch is fitted. Could be wrong though?

Its a CO detector, and comes under a different BS standard 50292......In domestic dwellings, it easier to wired into the smoke detection circuit, as what better, than having 3 or more sounders for early warning...there is no rule to say a locator or indicator should be fitted, but again it does make sense to show weather its a fire or CO contamination.

You would be correct. The reason is because the CO2 alarms should have a differing tone than the fire when in alarm, but they don't and Aicos way around this is to have a silence switch/control which then tells you if it's fire or CO2. It's in the install guide book thing.

Personally I don't think it complies but something is better than nothing.

Can we please get this correct it is a CO detector as in Carbon monoxide ....a CO2 is Carbon Dioxide....
Simlec, I would say the same, there is no reg, as it is combined with a fire detection system, so knowing what has set off the system, can only be a bonus, and aid quick detection.

 

[Simlec]

Sorry yes red wine regarding Co2
yes carbon monoxide and it's page 36 part 6 and states in Aico book that a controller must be used if mixing smoke alarms and carbon monoxide

 

[tazz]

It only advisory...but a think its good advice to fit. Problem here as stated before is we are dealing with 2 different BS standards, but in the real world, they are being used together within a system.
Sometimes I think Aico have a lot to answer for.

 

[Simlec]

It does say must in Aico MI

This is the bit I love in BS5839 pick any part..

"Use of this document
This British Standard takes the form of guidance and recommendations. It should
not be quoted as if it were a specification and particular care should be taken to
ensure that claims of compliance are not misleading.
Any user claiming compliance with this British Standard is expected to be able to
justify any course of action that deviates from its recommendations."

This again is the problem....fire/smoke alarms are BS5839 part 6 in a domestic dwellings...CO alarms are BS 50292, Aico have decided to combine the both in one system...so in this situation we can only follow both BS regs, and make a common sense approach, being some form of indication is needed to show fire or co. I think the conclusion is to indicate the difference

surely everyone here that does an ir on an unknown circuit first tests at 250 between (L+N) to E

Tin hat on.....can smoke ,heat and carbon detectors be all inter linked on sme circuit. Is the carbon sounder different from the smoke heat sounders.

 

[tazz]

yes, no reg saying the cannot be all linked.....but as we have pointed out in earlier posts, its a good idea to have a locator switch, so you can identify which detector has been activated

Will look up what is a locator switch.
