TCAS is programmed not to give alerts below 500 feet above ground.

One reason is that, to keep the system simple, TCAS resolution advisories only ever say to go up or down. That close to the ground a regular resolution advisory would tell one aircraft to dive into the ground--so the advisories are suppressed.
