LOL

get a wireman to help you for goodnes sake

last time online purchase a wired doorbell (not wireless) 1. turn out that it's DC hence cannot use. so now buy AC type. so must be work.

previous thread here: https://forum.lowyat.net/index.php?showtopic=3204283&hl=

why didnt u just get a wireless door bell instead and save from the wiring hassle?


anyway, it'ss 1 neutral, 1 earth, and 2 live - 1 of them is common

whatever you do.. Use test-pen to test all wiring (all green/red/black wiring). Make sure no current before do anything.. Your wiring maybe messed up by previous wiring man..

ohh, because the condo i'm staying already have a doorbell point. existing wiring come out from wall. so just fully utilize it. outside also already have a press button. just that without the chime.

no mess up, it is a new condo.

If you know nothing about electricity, it is strongly adviced that you do not DIY. There is a chance of injury and death, while you're fiddling. And if you install it wrong, to the people who use your door bell.

you just need to find out which 1 is L and N ....

normally Red and Black .... and do check the polarity at the door bell ... for suis no need ... check with multimeter if you have 1 ....

Try. If no fireworks then u are good to go.

4 wire door bells not connected like that.

That's for 2 wire door bells.

any model number? wiring diagram?

this is the diagram

ic, there is 4 connectors at the chime. will study through the link u given and see if i understand. no idea which colour to which connector?

I think i get it. Those 3 cable bundled together are Blue = Live, Black = Neutral and Green = Earth. Take a test pen and check if there is any voltage coming from the RED wire. If the test pen light up, dont do anything. If the test pen light doesnt light up, screw it on the E1 and E2 terminal. Blue and Black wire goes to the terminal down there marked with <AC 230V>. Green cable, screw it on the metal part of your doorbell. About the red cable, the best is to check for voltage first, if there is no voltage, separate them and do continuity test on them by using multimeter. Put the multimeter tester pin on each of the red cable, and press the door bell switch. If the meter goes up when you press it, then its confirmed the RED cable is the switch wire. If you wanna do them, turn of the main breaker before doing the work, thats because of the "loop" at the 3 cables bundled together with the connecter. If you somehow cut the Neutral that is from some other source, if might electrocute you. So be careful of the broken neutral . Its more dangerous then the Live wire because you cant see it coming

each colour of wire come in 1 pair. mean total got 8 wire. need to utilize 8 wires?

Red wire to E1 and E2. 2 Blue goes into 1 terminal marked AC 230V. 2 Black goes into ANOTHER terminal marked AC 230V. Green goes to metal parts of your doorbell unit, or screw it into the designated earth terminal screw if there is any.

Aisey, every doorbell comes with installation diagram leh. Just follow the diagram.

The usual will be :

2 cables for incoming 240v supply.
2 cables running to the switch and from the bell to connect and activate the bell. So u push the switch, shorting both cables activates the bell and ting tong loh

Kaotim.
