RF Doorbells - Replacement Transmitter or Bell-Push

Postby Alvin Wyllie » Mon Sep 23, 2013 6:08 pm

Friends of ours who have a house on three floors and use a 3-receiver RF door bell have had their transmitter/bell-push stolen 3 times. Does anyone know if there's a multi-receiver RF system available where one can connect a simple bell-push (at £2 to £3) connected by twinflex to the transmitter which is situated on the inside of the door??

Simply Build It

I have used RF door bells for some time and I have tried to find replacement door pushes when the water has got in without are real luck. If you buy expensive ones like "Friedland" then you can buy replacement transmitters and you can alter the bells or buttons to match each other.

However cheap ones from Lidi or Aldi etc are a pain even when they are done again likely slightly different. I tried to transmit on the 70cm frequency shown on packet with every sub tone the radio could be set to in order to find the correct tone required but failed to set off the bell. Or it was other way around and locking car would ring door bell.

As a result I would not expect to find any universal door push.

I bought three cheap door bells from Lidi and set them all to ring off the same door push so I have two spares.
