need some overhead door opener help

[s_ontario]

I have a 32 year old doorlec door opener works as good as it did when new i want to add remote control e-mailed doorlec and they don't have electrical diagram going back that far but said a 3 wire 24v receiver will work

can any of you look at the photos and give me any idea where wires would go

Thanks

You have a door-bell style button on the wall with two wires? If you do, then it is trivial to make a remote setup for it. (Modules, receiver and a couple of remote transmitters, can be bought many places.

If you have some other type of switch, post an image of it.

Its three button 4 wires up/down/stop commercial door opener 1/2hp 115v
bought a 3 wire 24v liftmaster security+ reciever as doorlec suggested

I wired the liftmaster to the 3 button on the wall and remote worked but door didn't stop I mean its wanted to go way past open postion to end of track against bumpers
removed the liftmaster receiver and door works as usual

sounds like it has not limit switches, or they are not adjusted correctly.

With the switch setup you describe, going wireless may be difficult.

its has up and down limit switches also has obstruction switch

but when i wired the receiver into the push button control it seemed to defeat the limit switches

wonder if its because the liftmaster receiver sends a continuous signal ? and not just a pulse to open pulse to close

But i know it needs to be wired into the opener control box not the push button control
