Remote Input Output (RIO)

Galaxy RIO's can be added to the RS485 Bus on the Galaxy 2 Series control panel. Each additional RIO
expands the system by eight zones and four outputs.

Addressing the RIO

The Galaxy RIO must be given a unique address before it is connected to a power supply (see Table 8. RIO
Addresses).The address is selected using the 16-way Rotary Address Switch (SW1).

Connecting the RIO

The RS485 (AB) line of the Galaxy RIO must be wired in parallel (daisy-chain configuration) with the RS485
(AB) line of any keypads connected to the system. The RIO requires 12 Vd.c. (range 10.5 to 16.0 V) and
40 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.
NOTE: A 3 Ampere Smart PSU can be fitted in place of a RIO.
