Smoke alarm problems

[euphoricmess]

Will try this, but how would i go about gently vacuuming.

Also, the head units both work fine downstairs, but not in the upstairs?

sounds to me like a crossed interconnection. remove head, then unclip cover over terminals. check that the same colours ( brown, black, grey ) are connected the same way round in both detectors. one detector will also have a T/E ( brown/blue) in L and N.

The instructions on my customers unit said hoover using a "soft brush head" but they didn't have one so I simply put the hoover "hose" near to the smoke alarm and let the suction do the job.

If this doesn't work, maybe you should get another sparky in - where are you based?

 

[euphoricmess]

Is this something a none skilled person should attempt, or am i better waiting to get someone who has experience in doing this?

Obviously to void from liability if i chose to do it, it would be of my own doing and not what someone suggest yada yada

If you have the instructions, taking off the detector part is straight forward.

Here's a picture of what you should see

as long as you islate before touching connections. first check if they are correct . it's just L - L, N - N, Link - Link.

The one downstairs, that i think is right looks just like that

The one upstairs has brown in brown, black with a thicker brown insulation in the middle one, and grey in the last one that should be blue. There is no blue wire upstairs at all

in the one downstairs there are two grey fat wires, that split into the relevent ones.

Upstairs there is not, there is only one fat wire that splits into the relevant ones.

yes. its just that you have to make sure that the brow/black/grey are in the same order on both. the brown sleeve is to identify the black as a "live". the grey , strictly speaking shoud be sleeved blue. generally it's brown =L, black=link, grey=N.

I have attached pictures. The first two are of the one downstairs, the second two are of the one upstairs.

Ignore the bad painting....

From the pics there may be a clear issue, but i dont want to prejudice your minds with it...

 

[telectrix]

i give up. are the grey and black the same way upstairs as down?

 

[Octopus]

looks like one has the grey and black in the incorrect connections!

 

[telectrix]

that's what i thought from the pics. if so , he's not read my previuos posts.

 

[euphoricmess]

Sorry I have read them, I just am wary of making any changes before i absolutely know what im doing.

I apologise if im coming across thick, im not, i just dont want to make any errors and am unsure of the affects any errors could cause.

So by that its clear the colour wires are not matching up.

So as I know the downstairs one works, im to change the one upstairs to match that of the one downstairs?

I'm guessing to say it's probably connected to the lighting circuit so make sure you isolate the circuit before you touch it.

Shame the installer didn't use "blue" sleeve on the "neutral" like they should have done

It has its own switch on the electricity fuse board thing, but before i try touching it i will turn whole switch board off. Is there anything else i have to do, earth myself or something?
