Looking for a FireAngel ST-620 smoke alarm replacement?

Replace your end of life ST-620 alarm with a FireAngel FA6615-R Optical Smoke Alarm with 5 year replaceable batteries or FireAngel FA6620-R Optical Smoke Alarm with 10 year sealed for life battery, without requiring a new base plate or leaving unsightly holes in your ceiling.

When fixing your alarm to the baseplate, it’s important to turn it as far as possible to ensure it is engaged and secure. If the ‘lugs’ at the rear of the alarm can be seen, then the alarm will be secure and can be installed. However, if you’re unable to turn the baseplate enough for these to be seen then we can offer an alternative baseplate.
