We have a garage door (Conqueror brand) that came with a keypad, you enter the code into the keypad and its sends a signal to the door and it opens. Picture below.

Its never worked well and seems to drain the batteries (I think). After a fairly short period of time when you push the buttons instead of beeping on each push (beep) you get the error tone instead (boop-beep) no matter what button you push and entering the code doesn't work. Generally when this starts happening I change the batteries and it seems to be OK again. Now its not even lasting 1 month between battery changes, so its time to get a new one.

Are these something standard that can be picked up anywhere, or would they be specific to our particular garage door unit.

I can of course ring Conqueror and try and buy one, but if it turns out they are standard items I can get anywhere then we'd probably be able to save some $$

EDIT: looks like they no longer trade, so we HAVE to find it somewhere else.

Is it wired or wireless??

Assuming its wired would one of these work?

It is wireless.

On the inside wall of the garage, coincidentally in approximately the same place, there is a button wired all the way back to the unit that when pushed opens the door from the inside. Perhaps @cyril7 's product could merge into that? Although how exactly to do this could be beyond my ability. And it would need to be merged, as we'd still want the button.

Getting a wireless one will be a PITA if its out of production and using a protocol your don't know...

I would look at getting a waterproof wired keypad drill a hole from the other side and look at piggybacking it off the other switch wiring....

Hi, so you say there is a button immediately behind the noted outdoor unit, that if momentarily pressed also opens the door? If so simply wire Relay1 Common/NO contacts across the button (assuming its also NO) and away you go, the installer manual explains how to add codes, it also can accept RFID cards. The catch will be that you need to provide 12-24VAC to power it, not too sure how hard that is for you.

Edit: if you provide more details as to layout and existing wiring it might help

If that is the case, some of the doors actually have a 12-24 supply at the door motor itself used to power a beam set, so you could use that if you door has these, you would just need to possibly replace then 2 core cable to the button with 4core to get the power to the keypad.

Another alternative for a keypad would be, this one from Aero NZ or this one from Jaycar

OK so its starting to sound like I may have some options that are in my capability zone. I will take some pics of the door motor unit and post when I get a chance.

If no 12-24V supply in the unit then I assume I would need to source the power from something like on of the power plugs in my garage (perhaps via an extension cable) and use some form of transformer. This might be beyond my skill level (or not legal), but if the unit doesn't have 12-24V I might explore this option with you all too.

Thanks for the help so far.

@cyril7 @sparkz25

Dumb question. My current bell switch has 2 wires going into it from the motor unit. I assume that when you press the button it must create/cut the circuit and that triggers the motor to start/stop.

If I get one of the keypads you pointed me to, do I wire the 12v wires into the 12v power input sockets in the keypad and that's it, or do I need to then send a wire back out again from one of the other sockets and back to the motor unit somewhere. I guess I am asking if the keypad mimics the way the bell switch behaves, or if it is more clever than that and uses an outgoing wire to carry the signal. The later sounds more secure to me, a bad guy cannot just pull of the external unit and connect the 12v wires together.

Probably a really dumb question, but this is all new to me.

I have taken a photo of the inside of the garage door unit. The cover was really difficult to get off, and unfortunately now the display seems to have stopped working. Doh, I must have broken something.

The wiring showing in the photo comes from a 2 wire button/bell switch on the inside of the garage, pushing it opens/closes the door. It is the white wires on the right, and they go into PB (P8?) and GND.

What I am needing to know is how to wire up one of the keypads suggested by other contributors. I am not into electronics so am a complete noob, but I am hoping someone can tell me what wires would go where. For example some like [and this is totally made up] "put the x wire from the keypad into GND, put the y wire from the keypad into 24v, put the zz wire from the keypad into PB"

EDITED FOR CLARITY

All help appreciated.

*bump*

This is still something I am interested in solving, I just got sidetracked.

Anyone able to help? I pretty much need hand holding which I understand can be a bit of a pain.

I've done what you are wanting to do for our setup at home.

WARNING: Please turn off the garage door unit before attempting anything and I am not qualified provide to advice.

First question is do you have a multimeter? If not, i suggest you get one. They are pretty cheap and will help you sort things more easily.

Second, i will make an assumption in the picture you have provided of the garage door unit that a 24V circuit will made between the +24v terminal and the GND terminal.

Powering the keypad

Assuming +24V and GND makes a circuit then this will power your keypad (CPT-DH16A-10T) that was linked in year earlier post. The installation manual says it is the red and black terminals on the keypad. Wire these with the wires (+24V and GND) that come from the garage door unit. Your key pad should now have power.

Now for the switching

Just think of the key pad as an automated push button. Push button normally activates when you close the circuit by pushing on it. So in this case we can assume that the circuit is NO or normally open.

We are going to use Relay2 on the keypad. But you could also use Relay one if you wanted. There will be 2 terminals on the key pad you need. RL2NO (normally open) and RL2COM. These are coloured blue and Purple. Or you could use Relay1 RL1NO and RL1COM. I don't think it should matter in this case.

On the garage door unit you are going to run wires to the same place that the white wires currently are. PB and GND on the board. You also want to keep the white wires as I assume they are used for the internal pushbutton. So there will be one wire that runs from Blue on the keypad to PB on the door unit and one wire that runs from Purple to GND. If it doesn't work this way you can run the Blue to GND and the Purple to PB. I'm pretty sure that the polarity doesn't matter on these.

Checking it works

Once you are comfortable with the wiring turn the main garage door unit back on.

Once you turned on the door should only activate once the relay is activated. This happens once you enter the correct PIN on the keypad, or press the internal push button. There will be a default PIN included in the instructions so once you have entered that you door.

Hopefully this gives you enough to work it all out. As I said earlier owning a multimeter makes this much easier, they are check and easy to use.

EDITED FOR CLARITY.

Thanks shim99, that is exactly what I wanted.

Quick question, what do I need the multimetre for? Would I be checking if I do have 24v across the +24V and GND on the garage door unit, and if so and once connected to the key pad checking that I get a voltage/current across the blue and purple on the key pad if the correct pin is inserted.

Or something else? As mentioned previously, I am a total noob at this stuff.

Yes, worth checking

You get 24V across +24V and GND, keypad can only be powered on 12-24V.
Check the voltage you get across PB and GND when someone presses the button. Relay on keypad can't take more than 30V.
Check the relay creates a circuit between NC and COM when activated.

You could wire it all up without a multimeter, but as a self described noob these are worth having and help you figure stuff out more easily for future projects.
