Smoke alarm

[aaelectric]

Have 3 smoke alarms in a house which are supposed to be interlinked but are not. The red light flashes every minute or so. Would this be because they are not interlinked. Green light is constant and are all new alarms?

 

[telectrix]

think you'll find that the red flashing every minute is either normal or a sign of weak battery, depending on the make and model. usually, however a weak battery will give an audible warning. suggest googling for makers instructions.

Try the test button. If the all go off simultaneously, then you know they are interlinked.

You can get raadio link bases to give you the interlink facility, an important function in my book that shouldnt be overlooked

 

[ezzzekiel]

could be radio with the flashing led (aico do this) press the link button to pair

If they are FireX smoke alarms, a red blink indicates that they are OK.

What make and model are they?

 

[aaelectric]

They are aico and are not interlinked as they are using two core t&e

 

[PC Electrics]

Where are you seeing t&e?
At the board? That'd be normal.
At all bases? Someone used the cpc as interlink?

Get the leccy back and get some radio bases installed if no link

do you have to use micc or fp200 to install smoke alarms in a house ?

Depends on the category of alarm required. Generally not in a house.

If they are Aico's check for radio link bases if there's t&e in everyone. If there is not any, shouldn't be hard to fit.
I've got a feeling the red light is battery low, but not flat as it will beep then. They also flash red to say they have been activated but silenced.
Best check the manufacturers instructions.

standard mains connected smoke alarms, so can i use 1.5mm t&e

 

[rich.250]

What size is the property?

 

[th3pony]

3 bed semi quite small

From what you've said I would probably say 1mm or 1.5mm t&e interlinked with 3c&e. Dependant on the requirements of the installation method.
