John would like to know: Can I use the GTO-FM136 with the Apollo 633 Gate controller? Will it work with the 635? If so, I think it would work with the 633. If it will work with the 633 controller, how do I wire it to the controller?
Answer: Yes John, you may either purchase a GTO-Pro Receiver or you can hard-wire it directly to the “open” input on your 633 board per the instructions outlined on the operators installation manual. Have questions regarding our products?
