How do you program it to an opener? I can’t find information anywhere. I just bought a home and the receiver is on both Allister Century 710 door control system.
The American 3800 only has 5 volts and from what I can tell will not power it. Can I add the external controller along with the wall mount 888lm to the red and white where you indicated?
I believe your best option when using an American model is to install the backup battery into the unit & then you are able to get 12 V from the charge wires of the battery.
hey! do you know which terminals are for door sensor...i need to connect magnetic sensor which actually gives "short" when door is closed so i need to brick a wire between 2 terminals...cant find any schematic anywhere.thank you
Depends where you are in this world :) Look out for 850LM or 860LM If outside installed or look in Europe for 860EV. Combine your search with LiftMaster and the part number
