I am using a 202U and my remotes to open my garage door (rollup) and my front gate. All of them are connected to the N-O terminals and make use of the momentary closure trigger.
The main issue is that if I accidentally push the button for my rollup garage door, and I’m on my way into my house, I might not notice it opened, and now the garage gets left open.
I’d like to add some custom programming to require me to press-and-hold one of the buttons for 2 seconds before the trigger occurs – this would prevent accidental openings of my garage.
I see, so this is to prevent accidental button press.
Our transmitter doesn’t have the 2-second delay to transmit function.
An alternative is to use combination key activation, for example, you can program button B+C to activate relay (so relay will only activate if pressed buttons B+C together).
Or you can use our relay to trigger a timer module (that activate after several seconds), and use that module to control your door.
