To illustrate the door bell that I was referring earlier... I wonder why there are 4 holes?? Upon closer check, every 2 holes at the bottom and at the top connecting to the same copper plate in it...

You just need to connect to 1 hole top and 1 hole bottom. Those are extra.

I think you better ask somebody experience to help you. Electric can kill. You need some basic knowledge to do.

Learn how to read the symmetric diagram. It already tell you from the symmetric diagram on the switch. Did you see the image on the switch?

So just connect to either one right?

I don't know of any door bell that run direct 240v circuit. Most of the door bell I seen are 4 wires, the Live (240v) and Neutral from the incoming are connect to one side of the transformer, another two wires is connect to the external switch (your outdoor switch), when the switch are press it will complete the circuit and your door bell will rang.

If you are unsure, better ask someone with electricity know how to help you.

Yes, I will not be the one installing but I am purely asking more. Too dummy in this area.

Anyway, for the external door bell button, if I install with a waterproof lid, I wonder will it be ok then?

I bet your outside wall is rough finish. So this cover will not able fully to seal the wall side. Water will sip in.

If you want to listen to the forumner advice here, go get a 4 wire door bell. It won't cost you must.

I know you won't going to press the bell. But you don't want kill your friend either.

But I just wonder why my friend house has been using this too for ages... Same model, as door bell at outdoor?

So this 240v will be sufficient to kill a person? Sorry ah side way a bit... I also saw those outdoor switches...Will it be safe then? I have some at the side

The finishing of the outdoor gate pillar is flat btw...

Because house door bell are run on lower Voltage. The switch do not pass high voltage.

So my switch above can pass thru standard voltage? In another words, both door bell button and door bell I got are rather alien here? I got them when I went Taiwan

Your switch can handle standard voltage (240v you mean?) But is crazy to use 240v for door bell switch. No matter how you water proof it, water will pass-through sooner or later.

Dunno... It says 10a 250v behind from the photo attached earlier??

But I saw my friend's house having the same unit like what I bought. It is a Panasonic-branded door bell model EBC700.

Tomorrow I go open up its case n see if it has just 2 or 4 connectors...

looking for Wireless Door Bell

I have then bought a Legrand-branded one with built-in transformer

I have learnt the hard way... Spent extra unnecessary... LoL!

Just wonder if I can actually add the transformer like 12V one to this 220v doorbell and this 220v door bell will still work?

Nope, that will not work. You need to made another circuit to drive the original circuit.

hi guys,

need ur help.. i just bought this door bell @ houz depot.. but confused with the wiring.. i have Red + Black + 2x White wire from the wall.. I know that the white wires are for the switch, and red and black wires for the power.. but how should I wire it to the door bell.. no proper instruction is attached with the door bell package..

attached is the DB pix:


Thanks!!

Try to check around the bell casing or box for an electrical diagram. And post it here. There is only 3 connection in your door bell. If can't find. Better go back to the shop and ask for a manual. Probably missing the manual.

just found out I bought the wrong door bell Schneider Model 99AC220 with 2 wirings after read thru this forum. Haiz waste of money oredy. Does anyone know where can I get the Schneider door bell with 4 wirings? Please share here.

Just found out that this is supposed to be the diagram.. in upside down.. haha.. didn't realize it earlier.. now need to figure out which one is for the L & N wire..
