Maybe MQTT on each pi, one publishes a "topic" when button pressed; the other "subscribes" to that topic and when received it rings the bell.
Python scripts can be used on both, uisng paho mqtt library.
OR set up passwordless SSH access between pizero and Pi3 so that pizero can run commands (to ring the bell) on the Pi3.
(can be done from a python script using subprocess.run)
