Rated 5 out of 5 by from Good fire alarm Seems good and easy to fit. I did want an all white exterior but the outer edge casing is moulded in grey rather than white plastic. OK but the description should make that clear.

Is the flashing light on this prominent?

Hi, is the flashing LED on this subtle enough that it could be placed on a bedroom ceiling? I'm looking for an alarm with a power light which isn't too distracting at night. Thanks.
Asked by: Gazbelfast
The FireAngel ST-621R Thermoptek Smoke Alarm can be located in a bedroom without disturbance. Due to the British Standarts, all smoke alarms are required to have this LED flash feature every 45 seconds.
