Wireless Receiver Kits
#1

I have 4 overhead doors. Can i buy 2 remote kits from Amazon and have button A on all remotes operate 1 door.

remote 1 button A - door 1
remote 2 button A - door 2
remote 3 button A - door 3
remote 4 button A - door 4

Also, will you be selling spare remotes through Amazon anymore? They have been unavailable for a while now.

#2

Each door is controlled by seperate relay, so yes.
You can program different buttons to different relays.

The next batch spare remotes is on the way to warehouse and should be available soon.
Thanks.
