Can the CADDX wireless receiver be connected back to a keypad or does it have to be mounted at the panel?

The Caddx NX receiver must be connected to the special "Aux Data Bus" connector on the M1 Control board. This requires an ELKWO35A wiring connector (sold separately). It cannot connect to the M1 data bus or keypad wiring.

NOTE: While the cable assembly is only 18 inches long, it is possible to remote the receiver up to 200 feet away using four conductor wire.
