We are missing the remotes for a Doorworks GDC12 garage door. According to the Doorworks documentation, this uses a 433MHz fixed code remote. I tried programming the door to work with a couple of cheap 433MHz fixed code remotes I had, but this was unsuccessful.


An off-the-shelf momentary relay switch is much cheaper than buying the original remotes, so I thought I would just add that instead, and connect it to the fixed button wiring.


The unit has four connectors for the 'photo eye', which presumably supply power for the sensor. Can anyone confirm if this supplies a usable DC voltage and if this is available with the photo eye jumper disabling that feature? I live 40km away from the property where this would be installed, but hopefully someone would have looked into this for automation purposes already.


I'm not looking for any smart device integration. Just a simple remote. Security isn't a major concern... there are still plenty of doors out there with 8-bit DIP switches and criminals haven't got smart enough to exploit those.

I haven't been able to get any usable power from the photoeye terminals on a very similar gdo12 unit. I ended up getting the backup battery option, and connecting a shelly device to that, and then using the dry relay contacts of the shelly to control the door.

Ge0rge: I haven't been able to get any usable power from the photoeye terminals on a very similar gdo12 unit.


The GDO12 seems to be sold under different brand names. Comparing this with the Doorworks equivalent, RD2, it appears the Doorworks does have a 24V DC pin on the roller door version, but not on the sectional door opener where the second pair is also used for the IR sensor. It doesn't specify which end to connect to the emitter and receiver, so I'm hoping it's DC on both and pulled low when the signal is broken.

I checked with the multimeter this morning and there is 24V on both of the IR pairs.


I've ordered a cheap relay board which takes 5-60v DC, so we'll see how that goes.
