Hi, I have a question. The developer door bell wiring has 4 wiring meant for the attached door bell photo.

However, the door bell I bought only has 2 contact point. I tried connecting it myself, one to live wire and one to neutral wire and installed it to a plug, it will ding when I press the switch and dong when I depress the switch.

How to make it work on developer wiring? Sifu pls help...

Or I bought the wrong one ???

If your house is land property and the switch is outside, do not use this type. You have to get the 4 wire type.

This type will connect the 240v to the switch. Which is dangerous.

If for condo, than connect as follow

My house is landed... So how do I connect? Is it that 2 wires are from the button and 2 are from the DB box, one is live and one neutral? So I joint live and one wire from the button onto the door bell while the neutral one together with another wire from the botton onto the 2nd wire connector?

About the 4 wire type is it has a built-in transformer to draw lesser voltage (assuming that is a 12-v door bell)? While the wiring will be 2 wires from the button at two connectors on the door bell while live / neutral on the other two connectors on the door bell?

4 wires is inside your house?

Mean 2 are to power the bell, 2 wires are the switch. When it short bell will ring.

4 wire door bell have 2 lower voltage connector joint to switch wire. Another 2 wire from DB to power the door bell. Get this if house is land.

2 wire door bell, just follow the picture. Live to the door bell. Neutral joint together with 1 of the switch wire. Than put a condom on it. Another switch wire direct to the door bell neutral side connector. So total is 4 wire connection.

Because I saw my friend house using the same model (2 connectors in it) so I bought the same type. Now if I want to use, how do I connect? I remember seeing 4 wiring on the wall in the house? 1 Live and 1 Neutral from the DB box and another two are from the button???

Later I go snap a photo to confirm... Is it usually 4 wires?

Put a condom on it. I like this Condom - safety, against pregnancy, against STD and against AIDS and now against electrocution. But how long can the condom last? Condom instruction said is one shot only

He.... Actually it call wire cap. Because it look like condom and provide safety joint too. So I called it condom lah.

It look like this.

Thanks guy... So for my wiring to be done is like

Live goes to one of the door bell connector
Neutral joint with the switch wire together with the wire cap (condom)
The other switch wire goes to the other door bell connector

The above will complete the circuit?

So if it is in the case of 4-connector door bell
2 lower voltage connector goes to the door bell switch
Live / Neutral from the wall goes to the other two connectors on the door bell

Am I right?

Get the bell that use the same wiring. If you have neutral outside, raining time + your outdoor switch leak your bell will continues ring. Worse if someone press the switch maybe electrocuted.

Weikee, dont frighten him la but that's a real good piece of advice.

Actually doorbell can be misused by thief. They press the bell ting tong ting tong............and no one answer, they know nobody at home and they come in for their business

Is mine the same wiring? I also have the door bell button ready with leak proof lid that protects from water going in... Will that suffice??

One more thing, I notice that the door bell button has two connecting holes up and two down. Why is it so? I that just need to connect 1x neutral.. What is the other for??

Will alarm with infrared sensor help?

Forget about door bell. Nowadays due to what i said no one want to install doorbell. Imagine you are in condo. Tingtong, noone home, they get in wait for you at the kitchen. When you come home they jump on you with a parang. Money, sex or life....It could be all of it...if you have no money. Not what I say, everyone think so.

So, how? no door bell? Today unlike yesterday your mobile phone is the door bell la. No need for door bell. How often people visit you? Once a month? Once a year?

Prevention is better than cure. Besides no door bell, just buy a dummy big to be seen camera at the door front as though you have a state of art cctv alram system. They choose another unit/house instead of yours. Similarly if your car has a visible steering lock at your parked car steering, they dont bother about your car. There are so many other cars.

Unless they know you are so rich and got so much money at home, once they target you are finished!!!! They cut wire to your alram, they take your recorder for the cctv...etc

Imagine the switch are wet, and someone press it, the body will flow current to the earth.

Get a correct bell, of all you know after few years your kids are playing the bell switch, if its configure via neutral is very dangerous.

Then what kind of door bell is not configured through neutral completing circuit?

Noted on this... My front will have 3 camera, of each sending emails to phones should it detects something... Hope it helps...

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..

No need to worry about the L vs. N connection.
No specific orientation, just ensure the AC 240V connected to the input of the step down transformer.
Refer to this post for further details.

If you compare the doorbell owned by psyntium vs. sw.boutique, the two are entirely different design.
However, the doorbell with two wires design still backward compatible with existing wiring (4 wires type).
It's just a matter of connections. For further assist, post the picture of the doorbell.

And please makesure your live wire RED and BLACK don't have supply or electric. Before you do the joining.

OFF the breaker to the wire or RCCB/main breaker if you don't no which 1. Pay attention to the safety.

oh tqtq.. thanks for the guidance!.. managed to get it work now..

I managed to take the photo of the door bell internal as per attached.
Please help to confirm whether I can use it for double storey house in return. If not any way to make the modification?

Here you go...
Conversion from 4-wires type to 2-wires type doorbell.
No major modification needed. Just add one terminal block connector.



Please take note of this type of doorbell design weakness!
If your doorbell switch located at outdoor and exposed to rain water, make sure you use the outdoor rated switch.
Non-outdoor rated switch will give you headache due to short circuit caused by water.
Short circuit will lead to nuisance MCB tripping.

Please don't do this kind of wiring, can kill the person pressing it when wet.

Yup, warning already given about the potential short circuit hazard!
That's the reason why there's a another variant design with step-down transformer.

I have a feeling this may not be an outdoor design door bell, or not made for Malaysia market.

Pros and cons...

Transformerless: Simple, reliable and low-cost. Suitable for indoor application like apartment.
Step-down transformer: Safer due to transformer isolation. However, the system always on standby mode and consume electricity.

Yup, this door bell I actually bought from Thailand. I buy this door bell mainly of the brand name and sound i like BUT very unfortunately you guy mentioned this is not suitable for outdoor. If u go to Schneider Malaysia website you may found they sell the weatherproof door bell switch BUT just cannot find this door bell sell in their Malaysia website.

Waterproof switch don't last forever chances it fail before your door bell, and may lead to leak.

I have change 2-3x the door bell switch for over 16yrs. Due to the degrade of the plastic and switch mechanism spoil. Mostly cause by the UV sun. While the indoor door bell last till now.

So when the switch mechanism spoil, the internal contact is expose. I cannot immediately get a new 1 and change. That is dangerous when somebody press the switch. But the switch is no longer there. His finger is going to touch that 240v contact inside. Specially at night.

I have to get a pvc tape to temporary seal the hole. While go and buy a switch. But lucky my door bell switch contact is not 240v or 2 wire bell.

I found this outdoor enclosure box for doorbell switch at lelong.com.my.
If you really like it, just go ahead install your doorbell. Ensure proper weather sealing for the switch.

Few months later you see lots of small friends inside.

Anyone knows how to modify the two wired door bell to four wired door please share. I was thinking to add step down transformer BUT don't know how to connect the wiring diagram. Appreciate ant sifu can help here.

You can't add step-down transformer to a doorbell system that required AC 240V as input power source.
Just buy the weatherproof switch to solve your problem.

How about a step down transformer plus a relay? Will it work?

Speaking of weatheproof switch and it's a bit off topic but just to ask if anyone installed outdoor switch sockets?

Is not the safest and convenient choice.

Why have to do all these trouble? Get one with 4 wires will do

You mean 3 points plug socket? I have one outdoor but is not expose. Have to switch off from inside when not use.

Yes, I have 2 3point plug socket outside but not exposed, currently have weatherproof cover-the plastic type. I believe one socket is for the future mini water feature outdoors. But don't know why need one more 3 point plug socket.

After seeing the concerns over weatherpoof cover etc, makes me wonder whether I should ensure extra protection.

I have a doorbell switch under Pieno range by schneider but not sure if also need to have cover?

If you are running low voltage door bell, don't need to have cover. Or if the switch are design for outdoor weather resistance. Even if you need I am not sure you have a direct fitting cover for that switch. Usually are universal and is slightly bigger.

This one is something solid

http://www.tlc-direct.co.uk/Manufacturers/...roof/index.html

Door Bell is 10A 250V. That link you provided looks solid but need transformer right?

The 3 point plug socket is 13A 250V

Door bell can handle that but you don't need that amount current. Most Important is it design for outdoor for 230v? If it leak out during raining someone pressing the door bell may get electrocute.

This one I am not sure? What should I do then?

Since you like and desperate for that doorbell.
Here you go...



Referring to above schematic:
● The doorbell switching done by AC relay.
● Relay energized by step-down transformer power supply.
● Outdoor switch running on low AC voltage.

Thanks for your schematic diagram.
As far as I know the 230v AC to 12v AC step down transformer is small enough to keep in the door bell box. BUT how about the AC relay? does it small enough to keep inside the door bell as well. I heard the AC relay need power supply, is it true?

Relay need power supply to energize the magnetic coil.
I think the transformer and relay can be fit into the casing.

Could you remove the small black plastic cover and provide me the picture of the circuit?
If you refer to first post (two-wires type) by TS, you can see the circuit of the unit.
I have another idea to modify the circuit to let the switch run on low voltage.

any wireless doorbell recommended for landed house (waterproof)?

I tried to use a wireless doorbell for landed house, but it failed miserably.

Not due to waterproof issue.

I sealed the button press unit with glue and it is waterproof as far as I can see.

But the problem I had was the battery. After using for a while, the dry cell voltage got out of operating range for the remote. I suspect it's due hot sun, the battery loses too much liquid and therefore the circuitory refused to work. When I open up the remote unit and change the battery, it works again. Multimeter the battery shows the voltage too high. It's not a case of voltage too low.

oh ya... battery really is the issue when explore under hot sun. I think we should go for this type--->Battery-free Wireless Doorbell

Never tried that before. Not sure if it is reliable.

The other thing to consider is the signal range. For landed, the distance between the remote and the receiver is normally much further than a condo unit.

why a hassle buying door bell ?

1) your hse should supply 5 wires , 2 wire ( from outside switch )
2) 3 wires ( L / N / E )

then

u buy legrand bell(build in transformer) . has 4 connection. 2 input for L/N (polarity does not matters here and it is used to convert 240 to 12V dc ) and 2 input for switch ( for connectivity )

legrand bell vs door bell, what's the difference ? Is it legrand bell a door bell too ?

Why you consider door bell a "hassle" ?

I Just bought from Tao Bao yesterday at only RM70/set. once I receive I will try it and let you know:)

Good good good ! I want to know.

Interesting...thus far I have not encountered any problem with cheapo wireless door bell (RM30). Obviously, the battery need to be changed from 3-6 months time (depending brand).

Maybe you are right.

Could be I happened to use a lousy battery which cannot withstand the heat from the Sun ?

But 3-6 months changing battery, I think it's too often already.

I think I decided not to put a doorbell. Mine is hardwired. Push switch is already in place. Wiring for the doorbell also in place. The problem is I cant find a wired doorbell that is not the two tone "ding dong" type.....

anyway mine is an apartment. I should not have anyone ringing my doorbell since nobody can come up anyway.

Yeah, really strange that nobody is coming up with wired door bell with electronics which play more choices of sound.

For ages, people still stuck with the electro-magnetic ding dong boring design.

legrand is a brand of door bell.

door bell is not a hassle but it become a hassle for some ppl here

I have no idea what you are talking about. Looks like you are only interested to promote legrand. LOL.

Guys..

My door bell wiring system as follows:

Bell (inside) - 2 red 2 black 1 green 2 naked wires
Switch (outside) - 1 red 1 black 2 naked wires (red and black are wired to the switch)
Door chime - built in transformer. 2 port for switch & 2 port for 220v

Can you please assist me on installing this wired door chime?

You need to know where is this switch wire go in the house. Is the switch wire have supply?

240v is dangerous but switch is not 240v, we based it on 6A. power socket is 20A. Hence, 6A is like ant bite

I don't care the switch is 20A or 100A. It is not important.

What I care is the safety. When 240v with outdoor, makesure it waterproof, weatherproof or whatever proof. To makesure it don't kill you.

Safety first.

u still dont get it. dont u.

I don't understand what you try to said.

You try 240v 6A, see got ant bite. even 1A of 240 enough to kill you. 240v AC with small amount of Amp will be enough to kill you. even with 0.5A

I m waiting what he try to explain here. Seems like we miss understand what he try to tell here.

My condo already have the switch outside for doorbell but no bell inside. The wiring for bell has 5 wires. 3 blue, 1 green, and 1 black. From post here, there are only 4 points for doorbell. So which extra wire i dont connect or should i get doorbell with 5 wires? Thanks in advance.
