I'm wanting to replace the wired smoke detectors in the house for Nest protect ones.
The wiring is as follows on the original
The plug that connects to the actual alarm has a brown, white and blue on. This connects to a chocky block to red, blue , white/grey, and yellow as follows.
Brown---red (x2)
White---yellow
Blue---blue & white/grey
Now I know there is 3 (Delta 530sca?) and they use the interlink between them. The Nest protect only needs power as it's uses WiFi for communication between them etc.
So I expect red 2 are live, the blue is neutral, but what is the yellow and the white/grey?
What happens if I do these one at a time and disconnect the interlink will it alarm?
Thanks for any help
