Compatibility
The RF RIO is compatible with Galaxy Control Panels 3-144 and 3-520.
Connecting the RF RIO
The  RS 485 (AB) line of the RF RIO must be wired in parallel (daisy chain configuration) with the RS 485
(AB) line of the keypad connected to it. The RF RIO requires 12 V d.c. (range 10.5 to 16.0 V) and 55 mA.
This can be supplied from the control panel power supply or from a remote power supply if the distance
causes a large voltage drop on the cable.
