Thank you for your reply, no not replacing the bell but adding an extra bell chime and the 8v 1a isn't adequate in the cu so bought 12v 1.5a as advised to replace it
Thanks again, yes i spoke to friedland supplier and he said i needed the 12v 2a (e3539n) unfortunatly its out of stock but he said while I was only using two chimes a 12v 1.5a (e3538n) would be ok.I need to take the 8v 1a transformer off the din rail and replace it with the 12v 1.5a transformer. Just asking for guideance with replacing ie switching RCD and mains switches off hopeing wiring straightforward.
Hi thanks for your reply, I spoke to Friedland bell chime suppliers they said that I could use a 12v 1.5a Transformer as the 12v 2a was out of stock, I have now replaced the 8v 1a with the 12v 1.5a and connected new bell chime in dinning room to the existing chime in the lounge and it works perfect. Thanks again
There are two ways.
1 Getting it to work.
2 Getting it to work within the parameters required by the regulations.
Unless you get permission from the consumer unit manufacture you can't fit anything to the unit. It is type tested and fitting any unauthorised part will invalidate the type testing.
You can fit a Friedland transformer in an enclosure but not in a consumer unit unless it is made by Friedland.
My door bell was designed to take an extra speaker remote from main one and a second door push which worked with a different sound to main one and was designed to run off either 6 x AA cells or a transformer. And there is no way that used even 1/2 an amp at 8v. I would say if the Friedland bell needs a 1.5A transformer then it should go in the bin and one should get a good one instead. Nearly said modern but mine has been working for 20 years so not really modern.
