remotes per relay

I am interested in giving a number of employees remotes. How many transmitter’s codes can be stored per relay?

Hello Tim,
Our 202U can support up to 510 Transmitters per receiver.

How do I go about getting the two remotes to operate one relay. I want to use a garage door opener with two remotes. Do I have to wire both relays in parallel or can a single relay respond to two separate remotes. Please advise as the easiest way to accomplish this. Thanks

You can use two remotes to control one relay.

Just program the remotes to the relay you want to use, it will naturally work.
