Direct retrofit for two existing i240C models that were originally installed when my house when it was first built, but expired in 2016 and none of the previous owners had changed them! It comes with the whole assembly and wiring but you shouldn't need it as it the existing mains wiring and existing plate will fit just fine. Interestingly, the listing says it doesn't come with batteries but these did (Duracell 9V), just with the pull tab needing to be removed before seating the battery. Good for 10 years! Bonus is my previous models had yellowed quite a bit on the plastic, these are plain white and will be much nicer on the ceiling!

Bought these two replacements for old 4870 models. New KF10’s fitted straight on to existing baseplate and connected onto wiring already in place for 4870’s, although new baseplate and wiring supplied in box. Nice bright green illuminated test button gives off quite a bit of glow in the dark ( a kind of emergency lighting ). Overall a good product at a good price.

Bought these as replacements for 10yr old models, slightly different ceiling fix but overall, good quality replacements and exactly the same inline electrical fixture with others around the house. Very satisfied with the product, and the supplier.

Bought as a replacement for a similar model which reached it's 10 year replacement date. I was delighted that the mains connector was the same as the old unit's so didn't need to mess about with the mains wiring. I highly recommend the product.

These are good plain and simple. Easy to fit, I used a (large) junction box to split the feeds required in all directions and a similar/separate arrangement for the physical interlink. it makes adding on for the future a lot easier. The only annoying feature is the larger than average hole (40mm) one has to make in the ceiling to accomodate the upright plug arrangement at the back of the unit - why can't it just lay flat so only a small hole would be required for the wires? Battery is included, which saves you a couple of quid!
