6150 to 6160 Fault

Switched out a 6150RF for a 6160 Keypad and now getting a “FAULT 100 RF RECEIVER”. Is there something that needs to be reconfigured and if so how?

The 6150RF doubles as a wireless receiver. Do you have wireless sensors using that as a receiver?

Are you using a 6160RF to replace it or just a regular 6160?

If you have wireless sensors and you are just looking for programming access using the alphanumeric keypad, you could reconnect the 6150RF, then just wire in the 6160 near the panel housing as a separate keypad for programming.
