The correct and professional way to wire the door bell and make it lasts years and years is using 4 wire. If you are using 2 wire means you risks electricity shock when pressing the door bell because 230 V is passing through the door bell button.
With the 4 wire method only an AC current of less than 16 V is being is being send to the door bell switch.
Even better use the telephone wire to carry the 16 volt from the door bell to the door bell button.
This is the best of the best way of installation saving you years of worry and money.

Yes boss. What can I help you.  tongue.gif

This wire pening pening. rclxub.gif
Kalau tak salah saya, dalam pic ni memang 4 wayar doorbell. Tapi kena cari keluar yang mana L, N dan 2 wayar untuk suis. Dalam 3 wayar hitam ni, mungkin salah satu ialah L. 

Ni ialah doorbell 2 dan 4 wayar pasang.

Dalam pic kalau 4 wayar,  jalan mungkin begini. Kalau 2 wayar doorbell, pic wayar agak keliru.

Apa yang perlu buat sekarang ialah guna multimeter cari keluar wayar2 ni yang mana satu dari switch, L dan N. Baru boleh pasang.

Cari electrician tolong kalau tak pasti.
