I have a similar problem to Seona, I have 3 x Ei141 smoke alarms, two of them work fine, constant green light and 1 x flash red light every 40 secs.
The third is bleeping - the time interval varies but can be as much as once every 15 secs to once a day. The red light is also flashing at irregular intervals, when silent, once every 40 secs, when playing up, can be every 10 to 15 secs. I have had the vacuum cleaner on it and thoroughly cleaned the side vents/slots - it seemed very clean before I started.
The sticker says replace 2018 - which suggests the heads are 6 years old (assuming a 10 year life span). The battery has been replaced with new Duracell. Can I still return this unit for inspection, even though it is 6 years old??
Thanks Elliot
