Fire Angel Smoke Alarm

I doubt it as all manufacturers recommend vacuuming it out at regular times and if the filters were 100% effective this would not be necessary.

Smoke alarms very rarely false alarm, as yours has done so twice in less than 12 hours and it was only installed just under 3 months ago I would get in touch with fire angel, It should be covered under the fire angel 5 year warranty.

Hello: Can you kindly advise if there is a known problem with this alarm (batch: 17110-17326J).  Supplied/fitted by a Brigade c one year ago, it's intermittently sounding full alarm (replace end Jul 2028), with no evidence of smoke and no other smoke/carbon monoxide alarms in the house sounding (inc another identical model - two were supplied).  After the first false alarm it has been vacuumed of dust but is still sounding intermittently.  This is NOT the low battery signal.

Tom: Thanks; FireAngel replaced under warranty.  I guess it's faulty - just surprised about the spontaneous alarm.  I don't know whether these are totally 'fly'-proof (midgies et al around in the summer)...

I had a Fire Angel ST750 fitted by the fire service in June and today it has sounded approximately 4 times (not the sound of a diminish8ng battery). There is no smoke that I am aware of although I'm not sure how much smoke is needed for it to be activated? The first time it sounded was at 7:30am and again 10 mins ago (4.15pm). Could something be smouldering?

I have exactly the same problem. It was fitted in 2019 and has been fine since but now keeps sounding a full alarm until I turn it off. I’ve had to take it down. Will replace battery if I can and see if that works.

I think you have taken the correct action contacting the manufacturer and I would contact the fire service they may fit a replacement.
