My uncle told me to always use a 22/4 wire for keypads, even on short runs.
I listened for a job in a small office building and ran into signal drop issues with a 200 foot run to the main panel. Turns out he was thinking of old analog systems, and for modern digital you really need to check the spec sheet for each panel. What's the longest run you've done with standard 22/4 before needing to step up the gauge?

Honestly, 200 feet on 22/4 for a keypad? That's pushing it, but I've seen worse work. The spec sheet is just covering their butts. I did a 175 foot run for a basic digital keypad on a cheap panel last year, same wire, and it's fine. People act like you need a perfect signal, but most of the time it just works until it doesn't. Your uncle wasn't totally wrong, he was just used to stuff that actually needed the thicker wire.

Got burned on a 300 foot run once... had to pull 20/4 to fix it. Now I just check the panel's spec sheet first, saves a headache later.
