Ei141 still beeps after battery replacement

Hi Thomas

I contacted Aico, as I could not think of any solution for you. They came back with:

'As the customer has done everything we would suggest and the Alarm is outside the 5 year guarantee he would need to get the Alarm s replaced. The new Alarms he would need is the Ei141RC & Ei144RC. They will still fit the same bases that are already there. I have attached the Data Sheets'

Not good news but at least you have an authoritative answer.

There are dedicated replacement heads available for the Ei140 smoke alarm family

Thankyou for your quick reply.

I feel kind of silly now but I was checking the batteries to make sure they matched the type mentioned in the sheets. The batteries were knockoffs, they said duracell on the battery itself but in unbranded cheap packaging. I bought some real batteries and the alarms are now good again.
