Replacement Alarm for FireAngel SI-610 10 Year Sealed Battery Optical Smoke Alarm - UltraFire ULLS10

Replacement Alarm for FireAngel SI-610 10 Year Sealed Battery Optical Smoke Alarm - UltraFire ULLS10

Q: Are these also compatible with the discontinued SO-610?

Thank you for your question. The FireAngel SI-610 and FireAngel SO-610 are identical but for the technology they use to detect smoke. The base plates are therefore the same so this replacement would be compatible with both.

Q: I have attached the new alarm to the standard plate in error. Can it be removed?

We had a problem fitting our new alarm so phoned FireAngel direct. They were extremely helpful even though we bought the alarm from Amazon.

Q: Does this have a light to illuminate hall / stairs in case of emergency please?

Fortunately, my alarm has not needed to operate in an emergency, so I can't say from experience, but no light comes on when I test the alarm, nor does the product description mention such a light. Indeed, the seller answers an identical question as follows: "Thank you for your question. The Ultrafire ULLS10 we provide does not feature an escape light, only an LED light that indicates operation and activation. " So I say no!

Q: Can you unscrew the standard plate once it is on?

I bought these as it said on ad that they replaced Fire Angel ,which is true, the new plate fits the old fitting so I don't have to make new holes for new fixing plate. They will unscrew from the old fixing plate but takes some time and know where to press.
